Empty space isn't empty. It hums with energy baked into the laws of physics — and a small group of researchers think they've found a way to tap it. Here's everything: the real physics, the devices, the controversy, and the missing experiment.
Heisenberg's uncertainty principle says you can never know a particle's position and momentum exactly at the same time. A consequence: energy can never be exactly zero. Even at absolute zero temperature, every quantum system retains a minimum "ground state" energy it can never lose. That's zero point energy.
It isn't theoretical — it's measured. The Casimir effect, a tiny attractive force between two uncharged metal plates placed nanometers apart in a vacuum, is direct experimental proof. Measured by Lamoreaux in 1997 to 5% accuracy.

The Humming Floor
A completely empty room at absolute zero still has a vibrating floor. You can't stop it — it's built into physics. ZPE is that vibration.
🌊
The Ocean Surface
Even on a perfectly calm day, the ocean is never flat. Constant tiny ripples, everywhere, always. The quantum vacuum is that ocean. The question: can you put a paddle in it?
📡
The Noise Floor
Every electronic circuit has random voltage fluctuations even when nothing is plugged in. ZPE is the universe's noise floor. The Casimir chip tries to run on that noise.
One-Sentence Summary
"Empty space isn't actually empty — it has a baseline hum of energy baked into the laws of physics, and these researchers are trying to build a chip that taps into that hum the way a solar panel taps into sunlight."
The Core Mechanism
The Casimir Effect — Live Demo
Place two uncharged conductive plates close together in a vacuum. The gap is too narrow to support long-wavelength vacuum fluctuations. More modes exist outside than inside — the outside pressure pushes the plates together. This force has been measured precisely since 1997.

In Plain Terms
Vacuum energy outside the gap pushes the plates together — the closer the plates, the stronger the push, growing 16× every time you halve the distance.
The Device
The Casimir Chip — Layer by Layer
The device Moddel's lab built and Harold White's Casimir Inc. is commercializing is a Metal-Insulator-Metal (MIM) diode paired with a Casimir cavity. Tap any layer for details.
☀ Gold Mirror (Top)100nm Au
Reflective top surface of the Casimir cavity. Suppresses ZPE modes in the gap below. Must be flat to <10nm to maintain precise cavity spacing. Deposited by e-beam evaporation, patterned by wet etch (KI/I₂).
↕ Casimir Cavity Gap ↕~200nm vacuum
The key innovation. ~200nm vacuum gap suppresses long-wavelength ZPE modes inside. More modes exist outside — creating an energy asymmetry. This asymmetry is what drives current through the MIM stack below, even at zero applied voltage. Created by etching a sacrificial germanium layer with H₂O₂.
⚛ Palladium Electrode (Upper)20nm Pd
Upper metal electrode. Palladium work function: 5.22 eV. Different from Nickel (5.01 eV) — this asymmetry rectifies tunneling current into net DC output. Must be thin enough for hot carriers to reach the insulator. Deposited at 0.3 Å/s.
▪ Aluminium Oxide Insulator2nm Al₂O₃
Critical layer. Exactly 2nm — thick enough to block classical current, thin enough for quantum tunneling (electrons cross in ~1 femtosecond). Deposited by Atomic Layer Deposition: exactly 20 self-limiting cycles of trimethylaluminum + water. Must be pinhole-free. If any check fails after deposition, strip and restart.
⚛ Nickel Electrode (Base)50nm Ni
Base metal electrode. Work function 5.01 eV — 0.21 eV lower than Pd. Creates built-in asymmetry in the tunneling barrier. Deposited by e-beam evaporation at 0.5 Å/s. Surface roughness must be <0.5nm Ra — any roughness creates pinholes in the 2nm insulator above.
Silicon Substrate4-inch wafer
100nm SiO₂ thermal oxide on p-type Si provides electrical isolation. RCA cleaned (SC-1 + SC-2 + HF dip) before deposition. Diced to 10mm×10mm chips. Every layer above patterned by electron-beam lithography at sub-100nm resolution.
Active area: 0.1µm × 0.2µm · Total stack height: ~400nm
Tap any layer to expand details
Moddel's lab measured ~70 W/m² output. Harold White's Casimir Inc. reports 1.5V / 25µA from a 5×5mm chip — about 37.5 microwatts. Enough to power an IoT sensor indefinitely. Not enough to power your phone.
In Plain Terms
Think of it like a sandwich. The bottom bread is nickel, the top bread is palladium, and the filling is a layer of aluminium oxide so thin it's only 10 atoms thick. Electrons can quantum-tunnel straight through that filling in a trillionth of a second. The gap above the sandwich creates an energy difference between inside and outside — like a pressure difference — that nudges more electrons one way than the other. That tiny imbalance is the current.
The Physics Problem
5 Paths Around Thermodynamics
The second law says entropy in a closed system at thermal equilibrium cannot decrease. Both conditions matter. Researchers aren't trying to violate the law — they're operating at its edges.
1
Geometric Non-Equilibrium
The Casimir cavity suppresses ZPE modes inside the gap but not outside — ZPE energy density inside ≠ outside. A solar cell doesn't violate thermodynamics because the sun creates a temperature gradient. Moddel's Casimir geometry creates an equivalent mode density gradient in the vacuum field.
Moddel / White approach
2
Non-Equilibrium Ratchet
Feynman proved a mechanical ratchet at equilibrium does zero net work. But Astumian and Hänggi showed that a ratchet driven by asymmetric noise produces net directed current — this is how molecular motors in biology work. If the Casimir cavity makes vacuum fluctuations asymmetric, the MIM diode becomes an Astumian ratchet.
Brownian motor framework
3
Fluctuation-Dissipation Theorem Exceptions
The FDT — every fluctuation paired with equal dissipation — only holds at global thermal equilibrium. It breaks down in systems with spatial asymmetry or separated fluctuation/dissipation channels. Daniel Sheehan (peer-reviewed, 2014) demonstrated physical systems where FDT fails measurably.
Advanced thermodynamics
4
Stochastic Electrodynamics (SED)
In the SED framework (Boyer, Puthoff, de la Peña), ZPE is a real classical electromagnetic field. Electrons reach ground state by balancing ZPE absorption and emission. Alter the ZPE field geometry with a Casimir cavity → shift that equilibrium → net energy flow becomes possible. Cole and Puthoff published this in Physical Review E.
SED / Puthoff / Boyer

Quantum Fluctuation Theorems
The Jarzynski equality and Crooks fluctuation theorem show that in small systems, individual thermodynamic trajectories can extract work beyond classical limits. At the scale of a MIM diode (0.1µm × 0.2µm, tunneling in femtoseconds), you're in exactly this regime.
Jarzynski / Crooks / small systems
⚠ The Honest Caveat
None of these paths are proven for this specific device. Moddel's 2021 data shows continuous current with 8 artifact tests passing. White's chip shows measurable output. But no independent laboratory has replicated either result. The cryogenic 4K test — ZPE is temperature-independent, thermoelectric artifacts are not — has not been published.
In Plain Terms
The second law of thermodynamics says you can't get energy from nothing — but it specifically applies to systems in perfect equilibrium. Researchers aren't claiming to break that law. They're claiming the Casimir cavity creates a subtle imbalance — like a slight slope in an otherwise flat surface — that lets energy flow in one direction more than the other. Whether that imbalance is real and large enough to be useful is exactly what's being tested.
The Formal Limit
Ford-Roman Quantum Inequality — How Long Can You Borrow?
Larry Ford and Thomas Roman showed in 1995 that negative energy density (energy below the vacuum level) can only exist for a limited time. The more energy you borrow, the shorter the window.
|ΔE| × Δt ≤ ℏ | More energy borrowed = shorter time window
Visible photon (2 eV)
~0.3 femtoseconds
MIM tunneling time
~1 femtosecond
X-ray photon (10 keV)
~6×10⁻²⁰s
Thermal fluctuation (kT)
~25 femtoseconds
The MIM tunneling time (~1 femtosecond) is right at the boundary of what the Ford-Roman inequality permits for visible-light energy scales. Each individual tunneling event can interact with vacuum fluctuations. Over many events, the statistical average returns to zero — unless the Casimir cavity creates a systematic asymmetry that breaks the statistical symmetry. That's Moddel's argument.
In Plain Terms
Physics has a rule: you can borrow energy from the vacuum, but only for an incredibly short time — and the more you borrow, the faster you have to pay it back. It's like a credit card with an instant due date. The MIM chip tunnels electrons so fast (one femtosecond — a millionth of a billionth of a second) that it's operating exactly within the window physics allows. The Casimir cavity's job is to tilt the odds so more borrows succeed than fail.
Why DIY Circuits Fail
The Frequency Problem: kHz vs 7 THz
The most common question online is "how do I build a zero point energy harvester circuit?" The answer is: you can't — not with coils, not with antennas, not with any circuit you can buy parts for. Here's the exact reason.
Electromagnetic frequency spectrum
DIY Coils Hz–kHz
Radio MHz
Microwave GHz
ZPE Peak 7+ THz
1 HzMHzGHzTHz
🔌
What coils actually do
A coil circuit harvests ambient radio frequency energy — stray EM radiation from power lines, WiFi, radio stations. That's real ambient energy harvesting. It's not ZPE. The energy comes from man-made transmitters.
⚡
Why ZPE needs THz
ZPE energy density peaks in the far-infrared / terahertz range (~7 THz and above). A circuit element needs to switch at that frequency to interact with it. Standard inductors and capacitors are many billions of times too slow.
⚛
Why MIM diodes work
Quantum tunneling has no "switching time" in the classical sense — an electron crosses the 2nm Al₂O₃ barrier in roughly 1 femtosecond (10⁻¹⁵ seconds). That's equivalent to operating at ~10¹⁵ Hz — 100 million times faster than THz.
The Gap in Numbers
A typical "free energy" coil circuit operates at ~1 kHz. ZPE peaks at ~7 THz. That's a frequency gap of 10 billion times. It's not that the coil is slightly too slow — it's fundamentally the wrong physics. The only device that can interact with ZPE is one that operates via quantum mechanics at the sub-nanometer scale.
So What?
What Could a Casimir Chip Actually Power?
Harold White's chip target output is 1.5V × 25µA = 37.5 microwatts from a 5×5mm area. As of May 2025 (JRE #2318), the bench output was 30 millivolts steady-state — the gap between 30mV and 1.5V is the current fabrication optimization problem. The power budgets below use the target to show what the technology enables when it gets there.

The Real Commercial Target
There are 15–20 billion IoT sensors deployed globally — most powered by coin cell batteries that need replacing every 1–3 years. At $0.50–$2 per battery replacement including labor, that's a $10–40 billion annual maintenance cost. A chip that eliminates battery replacement entirely, even at $5–10/chip, is immediately cost-positive. That's the commercial case — not phones, not homes, not cars. Sensors.
In Plain Terms
The chip isn't going to replace your phone charger — at least not yet. What 37.5 microwatts can do is power a tiny wireless sensor forever, with no battery to replace. The real money is in the 15–20 billion sensors already deployed that someone has to physically visit and swap batteries in. A chip that never runs out changes the economics of the entire sensor industry.
The Silent Killer
The Seebeck Effect — ZPE's Biggest Artifact Risk
The Seebeck effect is the most dangerous artifact in any ZPE measurement — and the one most often overlooked. It was identified as a critical gap in independent analysis of Moddel's published work.
Moddel's device uses two different metals. Different metals have different Seebeck coefficients — they generate voltage when there's a temperature difference across them.
Nickel S = −19.5 µV/K
→
Palladium S = −9.99 µV/K
Seebeck coefficient difference: ~9.5 µV/K. At nanoscale junctions this amplifies significantly — researchers estimate ~73 µV/K effective sensitivity. A temperature gradient of just 1 millikelvin (0.001°C) across the device generates detectable nanoamp current — indistinguishable from ZPE current without a temperature sweep test.

The Work Function Artifact
Nickel work function: 5.01 eV. Palladium work function: 5.22 eV. Difference: 0.21 eV = ~210 mV built-in contact potential. This acts like a tiny internal battery. If the measurement circuit isn't perfectly balanced, this potential drives a continuous nanoamp current — with zero ZPE involved. Moddel's same-metal control test (Ni/Al₂O₃/Ni) addresses this, but work function values vary with surface preparation and aren't perfectly reproducible.
In Plain Terms
The hardest part of this experiment isn't building the chip — it's proving the current you're measuring is actually from the vacuum and not from a dozen other tiny effects that all look identical. Every artifact listed here produces current that is indistinguishable from a ZPE signal unless you run the right control test. Moddel ran 8 of them. The one he hasn't published — cooling the chip to near absolute zero — is the one that would settle most of the remaining doubts.

The Key Difference
Moddel's work is more experimentally rigorous — peer-reviewed device results, artifact tests, detailed methods. White's work is more commercially advanced — a startup, physical chips, mainstream media. Neither has the other's strength. The ideal next step: White funds a Moddel-style artifact elimination protocol on the Casimir Inc. chip, including the 4K cryogenic sweep.
In Plain Terms
Moddel is the careful scientist — years of peer-reviewed work, published methods, controlled experiments. White is the entrepreneur — a physical chip, a startup, a Joe Rogan appearance. In an ideal world these two would be working together: White's chip tested with Moddel's rigor. That collaboration hasn't been announced. Until it is, the scientific community has Moddel's papers and the commercial world has White's chip, and neither camp fully trusts the other's evidence.
Scaling the Output
From 37.5µW to Useful Power — Array Math

At 10,000 chips per cm² (feasible with semiconductor fab), output approaches 375mW — enough to trickle-charge a phone or power a Raspberry Pi. The manufacturing challenge is yield: every chip in a series array must work. One dead chip breaks the string.
Why White's JRE Chip Matters
A 5×5mm chip is 25mm² = 2,500 single devices at 0.01mm² each, or many more at sub-micron scale. If the reported 1.5V/25µA is accurate, the internal architecture is likely a mixed series-parallel array optimized for output impedance matching. The exact architecture hasn't been published.
Target Applications — What 37.5µW Can Power
🚗
TPMS Sensors
Tire pressure monitoring sensors consume ~10–50µW average. A single chip → no battery, no replacement, permanently embedded in the valve stem.
🌕
Lunar Surface Sensors
White mentioned Intuitive Machines as a potential customer — moon surface instruments with no solar panel dependency and no battery degradation in the 14-day lunar night.
📱
Phone Charging Board
White described a 3.4W board (array of chips) that would charge a smartphone in ~3 hours. This is the roadmap target — not the current state. Requires ~90,000 chips operating in parallel.
🩺
Medical Implants
Pacemakers, glucose monitors, and neural stimulators run on 5–150µW average. A Casimir chip → batteryless implants with no surgical battery replacement every 5–10 years.
In Plain Terms
One chip produces a tiny trickle of power — enough for a sensor, not enough for a light bulb. The trick is stacking thousands of them. Series wiring stacks the voltage like batteries end-to-end; parallel wiring multiplies the current. At semiconductor manufacturing densities, a chip the size of your thumbnail could approach phone-charging power — but only if every single device in the array works perfectly, which is the hard manufacturing problem.

The DIA FOIA Document
The Defense Intelligence Agency released a document titled "Traversable Wormholes, Stargates, and Negative Energy" as part of the AATIP (Advanced Aerospace Threat Identification Program) declassification in 2018–2019. It explicitly lists zero point energy extraction as a potential advanced technology of interest. The document is publicly available via FOIA. This is why government-funded research in this area exists — it's not conspiracy, it's documented defense research interest in exotic propulsion physics.
In Plain Terms
Harold White wasn't chasing free energy — he was trying to solve faster-than-light travel for NASA. The energy chip was an accident: he built the Casimir cavity to test warp drive geometry and noticed it was producing unexpected current. That's actually how a lot of real discoveries happen — you're solving one problem and stumble into another. The warp drive program is still open. The energy chip is the part that became a commercial product first.
The Warp Bubble Crossover
White published a paper showing that the distribution of negative vacuum energy density around his pillar geometry qualitatively matches the exotic matter distribution required in an Alcubierre warp bubble. This is not a coincidence he dismisses — it's the reason he thinks ZPE harvesting and warp propulsion are two aspects of the same underlying vacuum physics. The ZPE chip is the energy chip. The pillar geometry was originally designed as the warp bubble shell.
The Venn Diagram Problem
Quantum mechanics and general relativity are two circles that don't overlap. QM describes the very small. GR describes the very large. They make contradictory predictions at their shared boundary. White's view: we need more circles — new frameworks that touch both. His work on the dynamic vacuum model is an attempt to add a circle that overlaps with both QM and GR simultaneously. The ZPE chip is the experimental test of whether that circle exists.
White's Key Innovation
The Pillar Architecture — Solving the "Wind the Watch" Problem
The standard Casimir device has a fatal flaw. White's pillar geometry is specifically designed to solve it.
The Problem: Standard Casimir Plates = a Battery, Not a Generator
Two flat parallel Casimir plates attract each other. When they collapse together, they release energy — but the device is destroyed. You get one burst of energy and then nothing. It's like a battery that works once. To do it again, you have to mechanically reset the plates, which costs more energy than you extracted. Standard Casimir geometry cannot produce continuous power from the vacuum because of this plate-collapse problem.
The Solution: Pillars in the Midplane
Standard Design — Fails
▬▬▬ TOP PLATE ▬▬▬
↓↓↓ ATTRACTIVE FORCE — plates collapse ↓↓↓
▬▬▬ BOTTOM PLATE ▬▬▬
Plates attract → collapse → one burst of energy → device destroyed. Must reset mechanically. Net energy: negative.
White's Design — Continuous
▬▬▬ WALL (mirror) ▬▬▬
▲ | PILLAR (isolated) | ▲
electrons tunnel: wall → pillar
▬▬▬ WALL (mirror) ▬▬▬
Walls don't collapse — they're the Casimir mirrors. Pillars in the midplane harvest the field. Continuous tunneling without device destruction.
White's metaphor: the atoll. Imagine a coral atoll — a ring of reef (the walls) enclosing a lagoon (the cavity). The walls don't collapse into the lagoon. The lagoon stays open. The pillars are structures built inside the lagoon that harvest the energy of the waves (vacuum fluctuations) without disturbing the atoll walls. The walls stay put. The pillars stay isolated. The current flows continuously.
How the Chips Are Made
White's chips are fabricated using a process that didn't exist a decade ago:
Nanoscribe 3D printing — the pillar geometry is printed at nanometer scale using two-photon polymerization with SU-8 2025 negative photoresist. This is commercial lab equipment, not semiconductor fab.
Electroless silver plating — the 3D-printed nanostructures are coated in silver (Ag) to make them electrically conductive. Silver is chosen for its reflectivity profile in the relevant frequency range.
Die-stacking — individual chip layers are stacked to multiply power. Millions of pillar cells on a single layer; multiple layers stacked = multiplicative output increase. Target: 100× per stack level.
How the Electricity Is Generated
The walls are electrically connected to each other. The pillars are isolated — not connected to the walls. Vacuum fluctuations drive electrons to tunnel from the walls to the pillars and back asymmetrically. The Casimir cavity geometry creates a mode suppression between wall and pillar that biases this tunneling directionally. The net result: a small but continuous DC current between the walls and the pillars. That current is the output.
Current State vs Target
As of White's JRE #2318 appearance (May 2025), the chip was producing 30 millivolts steady state — measurable, stable, continuous. The target is 1.5V / 25µA (~37.5 microwatts) — enough to power a tire pressure sensor or BLE beacon indefinitely. The gap between 30mV and 1.5V is the fabrication optimization problem: geometry, surface quality, pillar spacing, cavity depth. White was running 2-week sprint iterations at the time of the interview, down from 18-month development cycles when the program started in 2020.
In Plain Terms
The plate-collapse problem is why every introductory physics course says you can't get energy from the Casimir effect. The plates attract and crash — you can't run a generator that destroys itself. White's solution is to not use plates at all. The pillars sit in the middle of the cavity, isolated, like antennas. The walls stay fixed. Electrons tunnel across the gap continuously. It's the difference between a collapsing dam that releases energy once versus a turbine that runs the current through indefinitely.

What NOT to Try
These circuits are real, they sometimes produce measurable output — but none of them harvest zero point energy. Here's exactly why each one fails.
🔄
Bedini Motor
Captures ambient magnetic flux and back-EMF from motor coils. Real effect, not ZPE. Output is always less than input when measured properly.
🍩
Toroidal Coil Circuits
Induces current from changing magnetic flux. Harvests ambient EM radiation at radio frequencies. Nothing to do with vacuum energy.
📻
RF Harvesting Coils
These actually work — but they harvest radio wave energy from WiFi, power lines, and broadcasts. Legitimate ambient energy harvesting. Not ZPE.
🧲
Overunity Magnetic Generators
No verified overunity generator has ever passed independent power-in vs power-out measurement. Typically attributed to measurement error or fraud.
⚗️
Orgone / Scalar Devices
No physical mechanism consistent with known physics. "Scalar waves" and "orgone energy" have no experimental basis. Not related to ZPE research.
🔋
Capacitor Discharge Loops
Energy comes from the capacitor charge, not the vacuum. The "excess" energy claimed is typically measurement error in charge/discharge efficiency.
What Actually Could Work
Genuine ambient energy harvesting is real and growing: thermoelectric harvesters (temperature gradients), piezoelectric harvesters (vibration), RF harvesters (radio waves), photovoltaic (light). These are all commercially deployed today. A Casimir chip would add vacuum fluctuations to this list — but it requires nanofabrication, not a coil and some wire.

Moddel PRR 2021 has zero independent replications as of 2026. White's Casimir Inc. chip has zero independent replications. The fabrication barrier is real (Class 100 cleanroom, ALD, EBL) but not insurmountable for a university nanofab. First independent replication — positive or negative — is a Nature-level result.
P1 — changes the field either way
3
Seebeck Coefficient Separation
Ni/Pd has a Seebeck coefficient of ~73 µV/K. A 1mK thermal gradient produces detectable nanoamp current. No published paper has directly measured and subtracted the Seebeck contribution in real-time during ZPE current measurement. A co-integrated Seebeck sensor on the same chip would close this gap.
P1 — kills or confirms the artifact hypothesis
4
Cavity Gap Sweep
Casimir force scales as 1/d⁴. If current scales with the same exponent as gap narrows, that's a strong signature the Casimir cavity is the source. No published paper shows current vs gap spacing across a systematic range (50nm–500nm).
P2 — scaling signature
5
White's Emergent Quantization — Independent Test
White's PRR 2026 derives the hydrogen spectrum from a dynamic vacuum model with zero free parameters. If correct, it predicts specific corrections to atomic transition energies measurable with precision spectroscopy. No independent test of these predictions has been published.
P2 — theoretical verification
6
Johnson-Nyquist Rectification Quantification
A nonlinear MIM junction rectifies Johnson-Nyquist (thermal) noise into DC current — this is a known artifact. No paper has published a quantitative model showing how much JN rectification a Ni/Al₂O₃/Pd junction with these exact parameters produces, then subtracted it from the measured signal.
P2 — artifact quantification
In Plain Terms
The research isn't done. These are real open questions in peer-reviewed physics — not fringe gaps. A PhD student with cleanroom access who runs experiment #1 (the 4K sweep) and publishes the result, positive or negative, contributes something the field genuinely needs.
The Math
Key Equations — Derived and Explained
1. Casimir Force (Lifshitz Formula, ideal conductor limit)
F = (π²ℏc / 240) × (A / d⁴)
Where: ℏ = reduced Planck constant (1.055×10⁻³⁴ J·s) · c = speed of light · A = plate area · d = gap distance. The d⁴ dependence means halving the gap multiplies force by 2⁴ = 16. At d = 200nm, A = 0.02µm²: F ≈ 20 pN.
2. Simmons Tunneling Model (MIM current density)
J = J₀ × [φ·exp(-A√φ) - (φ+eV)·exp(-A√(φ+eV))]
Where: φ = barrier height (eV) · V = applied voltage · A = (4πs/h)√(2m) · s = barrier thickness. At φ = 2.0 eV, s = 2nm, V = 0: J ≈ 10⁻³ A/m². The asymmetry between Ni (φ = 5.01 eV) and Pd (φ = 5.22 eV) work functions creates a built-in rectification bias.
3. Seebeck Artifact Current (the silent killer)
V_Seebeck = S_AB × ΔT | S_NiPd ≈ 73 µV/K
Where: S_AB = differential Seebeck coefficient between Ni and Pd · ΔT = temperature gradient across the junction. At ΔT = 1mK: V = 73 nV → current through ~kΩ resistance ≈ 73 pA. This is comparable to reported ZPE signals. The kill test: measure S_AB independently, measure ΔT continuously, subtract S_AB × ΔT from all current readings.
4. Johnson-Nyquist Noise Power
S_I = 4kT/R | P_JN = kTΔf
Where: k = Boltzmann constant · T = temperature · R = resistance · Δf = bandwidth. At T = 300K, R = 1kΩ: S_I = 1.66×10⁻²³ A²/Hz. A nonlinear MIM junction rectifies this noise into DC. The ZPE signal must exceed this rectified JN floor, which scales with T — another argument for the 4K test.
5. Ford-Roman Quantum Inequality
|ΔE| × Δt ≲ ℏ
Energy borrowed from the vacuum must be returned within time Δt ≲ ℏ/|ΔE|. For visible-light energy scale (2 eV): Δt ≲ 0.3 femtoseconds. MIM tunneling time ≈ 1 femtosecond — at the permitted boundary. This is why the MIM geometry is specifically required; slower devices can't interact with ZPE modes at useful energy scales.

These are the actual arguments mainstream physicists make. Each one has a published response.
✗
Objection: "The second law forbids it"
Standard view: Any device that produces net current at thermal equilibrium violates the second law of thermodynamics. Full stop.
Response (Moddel): The Casimir cavity creates a geometric non-equilibrium condition — ZPE mode density inside the cavity ≠ outside. This is analogous to a solar cell, which doesn't violate the second law because the sun creates a photon flux asymmetry. The cavity creates a vacuum mode flux asymmetry.
Standard view: Ni and Pd have different Seebeck coefficients (~73 µV/K differential). Any sub-millikelvin temperature gradient produces detectable current. The measurement setup inevitably has gradients.
Response (Moddel): 8 artifact control tests were run. The same-metal control (Ni/Al₂O₃/Ni, zero work function asymmetry) produces zero current. The reversed-metal device (Pd base / Ni upper) reverses current polarity as expected for ZPE, not Seebeck. Temperature was monitored with ±0.001K precision.
The unresolved question: simultaneous real-time Seebeck subtraction has not been published
✗
Objection: "Johnson-Nyquist noise rectification"
Standard view: Any nonlinear junction rectifies thermal noise into DC current. At room temperature, JN noise in the MIM bandwidth produces detectable DC signal without any ZPE source.
Response: If JN rectification were the source, current should scale with temperature (S_I ∝ T). The cryogenic 4K test would show current dropping toward zero. If current stays flat at 4K, JN rectification is eliminated. This test has not been published.
The 4K test is decisive for this objection specifically
✗
Objection: "No independent replication"
Standard view: Any result that matters gets independently replicated. Five years after Moddel PRR 2021, there is none. This is a strong prior against the result being real.
Response: The fabrication requirements are genuinely extreme — 2nm ALD uniformity, sub-100nm EBL, Class 100 cleanroom with e-beam evaporator. This is not a tabletop experiment. The barrier to replication is technical, not logical. The same barrier applies to many nanofabrication results that are now accepted.
Absence of replication ≠ evidence of absence — but it is a legitimate concern
✗
Objection: "Vacuum energy can't be extracted — it's the ground state"
Standard view: ZPE is the minimum energy of a quantum system. You can't extract energy below the ground state, by definition.
Response: The Casimir cavity doesn't extract energy from the vacuum uniformly — it creates a spatial asymmetry between two regions (inside vs outside the cavity). Energy flows from higher-density to lower-density vacuum modes, exactly as photons flow from hot to cold. The total vacuum energy isn't reduced; the spatial distribution is temporarily asymmetric.
The analogy: you can't extract energy from a flat ocean, but waves can do work
In Plain Terms
The skeptics have real points — especially on the Seebeck effect and Johnson-Nyquist noise. The researchers have real responses. What's missing isn't argument — it's the one decisive experiment (4K cryogenic sweep) that would settle objections 2 and 3 simultaneously. The debate is stuck because nobody has run it.

Glossary
ALD — Atomic Layer Deposition. Deposits one atomic layer per cycle via self-limiting chemistry. 20 TMA+H₂O cycles = exactly 2nm Al₂O₃. Only method that achieves uniform 2nm films.
Casimir Effect — Attractive force between two uncharged conductive plates in vacuum caused by suppressed vacuum modes in the gap. First measured by Lamoreaux (1997) to 5% agreement with theory.
Casimir Cavity — The ~200nm vacuum gap in the device. Suppresses long-wavelength ZPE modes inside, creating mode density asymmetry vs. outside. This asymmetry is the proposed energy source.
EBL — Electron Beam Lithography. Focuses electrons to pattern features below 100nm. Required for the 0.1µm × 0.2µm active device area. ~$2,000–$5,000/hr cleanroom cost.
FDT — Fluctuation-Dissipation Theorem. States every fluctuation is paired with equal dissipation at thermal equilibrium. Breaks down when spatial asymmetry or non-equilibrium conditions exist.
Femtosecond — 10⁻¹⁵ seconds. One millionth of a nanosecond. MIM tunneling time ≈ 1 femtosecond. The Ford-Roman inequality permits vacuum energy interaction at this timescale for visible-light energies.
Johnson-Nyquist Noise — Thermal noise current in any resistor: S_I = 4kT/R. A nonlinear MIM junction rectifies this into DC — a known artifact that scales with temperature T.
MIM Diode — Metal-Insulator-Metal diode. Two dissimilar metals separated by a tunnel-able insulator (<3nm). Electrons cross via quantum tunneling in ~1 femtosecond. No semiconductor junction — pure quantum effect.
SED — Stochastic Electrodynamics. Classical electromagnetic framework in which ZPE is a real background radiation field. Predicts hydrogen ground state without quantum mechanics. Basis for Cole-Puthoff ZPE extraction theory.
Seebeck Effect — Thermoelectric voltage generated by a temperature gradient across dissimilar metals. Ni/Pd coefficient: ~73 µV/K. The primary artifact concern in ZPE current measurements. Temperature-dependent — unlike ZPE.
Simmons Model — Analytical model for tunneling current through a trapezoidal barrier in a MIM junction. Predicts I-V curve shape. Used to verify insulator thickness and barrier height from electrical measurements.
Work Function — Energy required to remove an electron from a metal surface to vacuum. Ni: 5.01 eV · Pd: 5.22 eV. The 0.21 eV difference creates built-in asymmetry in the MIM tunnel barrier — the rectification mechanism.
ZPE — Zero Point Energy. The ground-state energy of a quantum system — non-zero due to the Heisenberg uncertainty principle. The vacuum contains ~10¹⁰⁷ J/m³ in ZPE (Planck cutoff). The Casimir effect is its most directly measured consequence.
Quantum Tunneling — Quantum mechanical phenomenon where a particle crosses an energy barrier it classically cannot. MIM tunneling: electrons cross the 2nm Al₂O₃ barrier with non-zero probability in ~1 femtosecond. Probability decays exponentially with barrier thickness.
Pillar Architecture — White's structural innovation. Vertical metal posts span the Casimir cavity gap, holding the two plates at fixed separation while electrons tunnel across. Solves the plate-collapse problem: Casimir attraction would otherwise pull flat plates together. Fabricated via Nanoscribe 3D printing.
Nanoscribe — Commercial 3D printer using two-photon polymerization. Prints structures at nanometer precision using SU-8 2025 photoresist. Used to fabricate White's pillar geometry — the support structure inside the Casimir cavity.
Die-stacking — Technique borrowed from semiconductor packaging: stacking multiple chip layers vertically. Each stack level multiplies power output ~100×. Allows a compact module to reach useful power levels without increasing die footprint.
Limitless Space Institute (LSI) — Nonprofit co-founded by Harold White and Brian K. Kelly (former NASA JSC Director) in 2020. Focused on long-duration spaceflight and advanced propulsion research. White's nonprofit vehicle before founding Casimir Inc. in 2023.
TRL (Technology Readiness Level) — NASA's 1–9 scale for technology maturity. TRL 1–2 = basic principles observed. TRL 3 = experimental proof of concept. TRL 9 = flight-proven. ZPE harvesting is currently at TRL 2–3: anomalous current reported, artifact elimination (4K test) not yet published.
Broader Context
Related Fields — The Landscape
ZPE research doesn't exist in isolation. These adjacent fields share physics, techniques, or fabrication methods.
Rectenna Research
Optical rectennas (optical antennas + MIM diodes) harvest infrared and visible light without semiconductors. Same MIM stack, same femtosecond tunneling physics. Solved the "how do you build a THz rectifier" problem. ZPE harvesting is rectenna operating with vacuum fluctuations as the input instead of incident photons.
Molecular Electronics
Single-molecule junctions — a molecule bridging two electrodes, 1–3nm gap, quantum tunneling dominant. Shares the Simmons model, similar fabrication challenges. Research in asymmetric molecular junctions for rectification directly informs MIM design principles.
NEMS / MEMS
Nano/Microelectromechanical systems. Casimir force is the dominant interaction force at sub-micron separations — a major engineering problem (stiction) in MEMS devices. NEMS researchers have developed the most precise Casimir force measurement techniques. Their fabrication methods directly apply to Casimir cavity construction.
Thermoelectrics
Harvests waste heat via Seebeck effect. Competing ambient energy harvesting technology — commercial today. The Seebeck effect in Ni/Pd is also the primary artifact concern in ZPE research. Understanding thermoelectrics deeply is required to rule out Seebeck contributions in any ZPE measurement.
Quantum Thermodynamics
Studies work, heat, and entropy in quantum systems at nanoscale. The Jarzynski equality and Crooks fluctuation theorem show small systems can transiently violate classical thermodynamic limits. Provides the formal framework for why MIM-scale devices operate in a regime where classical thermodynamics doesn't fully apply.
Dynamical Casimir Effect
Moving mirrors in vacuum create real photons from vacuum fluctuations — experimentally confirmed (Wilson et al., 2011). Related to but distinct from static Casimir force. Demonstrates that vacuum fluctuations can be converted to real photons under the right conditions — relevant theoretical context for ZPE harvesting arguments.

Steve Lamoreaux
Professor, Yale University · Experimental Physics
First person to precisely measure the Casimir force (1997), agreeing with theory to 5%. His measurement transformed the Casimir effect from a theoretical prediction into an experimentally confirmed physical fact. No connection to ZPE harvesting claims — purely foundational measurement physics. His 1997 paper is the bedrock citation for this entire field.

Bernard Haisch
Astrophysicist · Former NASA / Lockheed Martin
Co-authored the "ZPE as the source of inertia" paper with Rueda and Puthoff (1994) — proposing that mass itself arises from interaction with the zero point field. Co-filed the foundational Casimir cavity patent with Moddel. Bridges the gap between ZPE-as-cosmological-fact and ZPE-as-engineering-opportunity.

Harold Puthoff
Director, Institute for Advanced Studies · Austin, TX
Pioneer of Stochastic Electrodynamics (SED) — the framework in which ZPE is a real classical electromagnetic background field. Co-authored the Cole-Puthoff PRE 1993 paper showing ZPE extraction isn't thermodynamically forbidden. Also connected to AATIP government program. The theoretical backbone behind both Moddel's and White's frameworks traces partly to his SED work.
Key paper: PRE 48, 1562 (1993)
Larry Ford & Thomas Roman
Tufts University · General Relativity / Quantum Field Theory
Derived the Ford-Roman quantum inequality (1995): negative energy density can only exist for a time Δt ≲ ℏ/|ΔE|. Sets the fundamental timescale constraint that any ZPE harvesting device must satisfy. Their work is why MIM tunneling (~1 femtosecond) is specifically required — not a design choice, a physics constraint.

Zero point energy has been co-opted by wellness influencers, manifestation coaches, and pseudoscience marketers. This has made legitimate research harder to take seriously. Here's the hard line between physics and fiction.
The Problem
Searching "zero point energy" returns Lynne McTaggart's "The Field," Esther Hicks's "Abraham" channeling, biofield healing devices, and reiki practitioners — before it returns Moddel's Physical Review Research paper. This page exists to fix that.
🌿
NOT: Biofield / Healing Energy
Lynne McTaggart's "zero point field" and similar wellness concepts use the term metaphorically. The actual ZPE in physics is a quantum mechanical ground-state energy — it does not interact with biological intention, emotions, or consciousness in any measured way.
🧘
NOT: Reiki / Energy Healing
Reiki practitioners sometimes invoke ZPE as a scientific basis for healing energy. Casimir force exists and is measured — but it has no documented mechanism for interacting with living tissue at therapeutic scales. These are unrelated phenomena.
🌀
NOT: Free Energy / Perpetual Motion
ZPE harvesting would not be "free energy" in the thermodynamic sense. The vacuum has energy, but extracting it requires a carefully engineered non-equilibrium system. It would not power itself indefinitely without the Casimir cavity geometry doing work on the vacuum.
🧲
NOT: Coil Circuits / "Orgone" Devices
Coil circuits sold online as "ZPE harvesters" capture ambient radio frequency signals — not zero point energy. ZPE operates at 7+ THz. Coils work at kHz. The frequency gap is 10 billion times. No coil has ever measured a ZPE signal.
💭
NOT: Manifestation / Law of Attraction
Some coaches use ZPE as a physics-sounding explanation for the law of attraction. Quantum vacuum fluctuations have no documented mechanism for responding to human thought or intention. This conflation misrepresents both the physics and the psychology.
⚛️
ACTUALLY IS: A Measured Physical Force
The Casimir effect — a direct consequence of ZPE — is measured to 1% precision in university labs. It causes MEMS devices to stick together. It's a real engineering problem in nanofabrication. That's what Moddel and White are trying to turn into a power source.
In Plain Terms
Zero point energy is a real, measured quantum phenomenon. It is not a spiritual force, a healing energy, or a metaphor for consciousness. The research on this page — Moddel's PRR 2021 paper, White's chip — is real peer-reviewed physics. The wellness industry borrowed the name. Don't let that discredit the science.
The Core Objection
Does This Violate the Second Law of Thermodynamics?
This is the first thing every physicist asks. It deserves a direct, rigorous answer — not a dismissal.
The Short Answer
Moddel's argument: No — because the second law applies to systems in thermal equilibrium, and a Casimir cavity creates a local non-equilibrium by geometrically suppressing vacuum modes. The device operates outside the law's strict domain, not in violation of it. The debate is whether this argument is correct — not whether the second law is wrong.
1
The Kelvin-Planck Statement
No device can convert heat from a single reservoir into work with 100% efficiency. The objection: ZPE appears to come from the vacuum "reservoir" — so this should apply. Moddel's counter: The vacuum is not a thermal reservoir in the classical sense. Its mode structure can be geometrically modified by the Casimir cavity, which classical thermodynamics did not anticipate.
2
The Szilard Engine Analogy
The Szilard engine shows that information has a thermodynamic cost (Landauer's principle). The parallel: The Casimir cavity acts as a "Maxwell's Demon" that selects which vacuum modes interact with the diode. The debate: Does creating and maintaining the cavity geometry require more energy than is extracted? Moddel argues the cavity is a static structure requiring no ongoing energy input once fabricated.
3
The Fluctuation Theorem (Jarzynski Equality)
Modern non-equilibrium thermodynamics (Jarzynski, 1997) allows small systems to temporarily violate the second law in a statistical sense. The implication: At nanoscales, momentary work extraction from equilibrium fluctuations is permitted — it is only prohibited on average over time. A MIM diode rectifying vacuum fluctuations could exploit this window if the rectification is asymmetric enough.
4
The Solar Cell Analogy
A solar cell does not violate the second law even though it produces electricity from photons. This is because the sun is at a different temperature (~5,800K) than the Earth (~300K) — there is a gradient. Moddel's argument: The Casimir cavity creates an asymmetry in vacuum mode density (inside vs. outside), analogous to a temperature gradient — a local non-equilibrium the diode can exploit.
The Honest Verdict
No published theoretical proof definitively resolves this. Moddel's argument is internally consistent and published in peer-reviewed journals. The strongest counter-argument is that any cavity that suppresses vacuum modes on the inside must emit them on the outside — restoring equilibrium. The decisive arbiter will be the experiment, not the theory. Specifically: the 4K temperature sweep described in the next section.
The Missing Experiment
The One Test That Would Force Scientific Engagement
There is a single experiment that would eliminate the most common artifact explanations in one measurement — and it has not been published. This is the most important gap in the current evidence base.
The Test: Cryogenic Temperature Sweep at Zero Applied Voltage
Measure current output from the device continuously as temperature is swept from 300K (room temp) → 77K (liquid nitrogen) → 4K (liquid helium), with zero volts applied. Log everything. Run for 24 hours at each temperature.
🌡️
ZPE Signal (Predicted)
Temperature-independent. ZPE exists at absolute zero — it's the ground state. Current should remain flat from 300K to 4K. If it stays constant: thermoelectric artifacts are eliminated.
🌡️
Seebeck Artifact (Predicted)
Scales linearly with temperature. At 4K, thermoelectric current approaches zero. If current drops → artifact confirmed. The Ni/Pd Seebeck asymmetry (~73 µV/K) disappears near absolute zero.
📊
Johnson-Nyquist Noise (Predicted)
Also scales with temperature (S_I = 4kT/R). At 4K, thermal noise is 75× lower than at room temperature. If measured current tracks this: noise artifact confirmed.
Moddel's PRR 2021 paper reports measurements at room temperature. Temperature-dependent data is referenced but not published at cryogenic temperatures. White's chip has been demonstrated at room temperature. Neither team has published the 4K result.
Why This Matters for Scientific Credibility
Without the cryogenic sweep, every skeptic can invoke the Seebeck effect and be correct — because the measurement hasn't ruled it out. With the cryogenic sweep published: if current is flat, the scientific community must engage on the physics rather than the artifacts. This single dataset would change the conversation. The cost to run it: a cryostat rental (~$500–$2,000/day at a university lab) and a Keithley 6430 SMU (~$15K). This is the cheapest path to a Nature/Science submission.

If Moddel's numbers hold, ZPE Casimir chips would be competitive with solar cells for power density — but work 24/7 without sunlight. White's current chip is in the "forever IoT sensor" tier. Scaling to smartphones or grid power requires 8–12 orders of magnitude improvement and hasn't been demonstrated.

Frequently Asked Questions
Yes — it is a directly measured quantum phenomenon. The Casimir effect, first measured by Sparnaay in 1958 and precisely by Lamoreaux in 1997, is irrefutable experimental proof that ZPE exists. The open question is not whether ZPE exists, but whether a device can extract usable power from it.
Unknown. Moddel's lab has published peer-reviewed results showing anomalous current from a Casimir-cavity-adjacent MIM diode. Harold White's chip reportedly produces 1.5V/25µA. Neither result has been independently replicated. Until a third lab reproduces the result, "we can use it" cannot be stated as established science.
Three reasons: (1) The field has been polluted by decades of pseudoscience claims, making legitimate researchers reluctant to engage publicly. (2) The results are preliminary — no independent replication exists. (3) The theoretical mechanism (Casimir cavity creating vacuum mode asymmetry) is genuinely controversial among physicists. Moddel has published in Physical Review Research, a respected APS journal. It isn't being suppressed — it simply hasn't cleared the bar of independent replication yet.
Harold White is a credentialed physicist with 15+ years at NASA Eagleworks, where he led advanced propulsion research. His February 2026 paper in Physical Review Research is peer-reviewed. Casimir Inc. is a real company with disclosed investors. None of this constitutes proof the device works as claimed — but it is not a scam in the sense of fabricated credentials or fraudulent fundraising. The scientific question is open.
Three things: (1) A cryogenic temperature sweep from 300K to 4K showing temperature-independent current at zero bias — this rules out thermoelectric and thermal noise artifacts. (2) Independent replication by a lab with no financial connection to Moddel or White. (3) A scaling demonstration — current linear with device area. If all three are published in peer-reviewed journals, ZPE harvesting would be considered established science requiring explanation, not dismissal.
Moddel argues no — because the second law applies to closed systems in thermal equilibrium, and a Casimir cavity creates a local non-equilibrium. The device is more analogous to a solar cell (which exploits a photon temperature gradient) than a perpetual motion machine. Many physicists disagree. The question is genuinely open at the frontier of thermodynamics. See the Second Law section on this page for the full argument.
White left NASA at the end of 2019. In 2020, he co-founded the Limitless Space Institute (LSI) — a nonprofit advancing long-duration spaceflight research — with Brian K. Kelly, former NASA Johnson Space Center Director. In 2023 he founded Casimir Inc. as the commercial spinout, based in Houston, TX. The cadence shifted from 18-month development cycles to 2-week hardware sprints. He appeared on Joe Rogan #2318 in May 2025 with physical chips and published a theoretical framework paper in Physical Review Research in February 2026.
No. Casimir Inc. is a private company as of 2026. Harold White founded it in 2023 in Houston, TX. It has disclosed investors but has not filed for an IPO or gone public. The company's current focus is demonstrating a commercial IoT sensor product, not a public offering.
Garrett Moddel is a professor of Electrical, Computer and Energy Engineering at the University of Colorado Boulder. He has spent decades researching quantum rectenna devices — diodes that harvest electromagnetic energy at optical and THz frequencies. His 2021 paper in Physical Review Research showed a Casimir-cavity-adjacent MIM diode producing continuous current with 8 artifact control tests passing. He holds multiple patents in this area. He is one of the few credentialed physicists publishing peer-reviewed ZPE harvesting research in mainstream journals.
No — and this distinction matters. "Free energy" in popular usage implies energy from nothing, violating thermodynamics. ZPE harvesting, if it works, would extract energy from the quantum vacuum — a real physical field with measurable energy density. The vacuum provides the energy source; the Casimir cavity geometry provides the asymmetry that allows a net flow. It's analogous to a solar cell: the sun's photons are the source, the p-n junction is the asymmetry. Neither violates thermodynamics. ZPE harvesting also should not be confused with Gibbs free energy (ΔG) — an entirely separate thermodynamic concept from chemistry.
Moddel's experiment uses a flat Casimir cavity placed adjacent to a separate MIM diode — the cavity and the rectifier are distinct structures. White's Casimir chip integrates the Casimir cavity directly into the MIM junction using a pillar architecture: vertical metal posts maintain a fixed gap, with the junction spanning the space between pillar arrays. White's design solves the "plate collapse" problem that plagued flat cavities, where Casimir attraction pulls the plates together. The pillar midplane stays fixed while electrons tunnel across. The two approaches are complementary, not competing.
Both figures are real — they describe different things. 30 millivolts is White's current output as of the JRE #2318 interview (May 2025) — the actual measured voltage from the chip at that point in development. 1.5V / 25µA is the target specification — what the chip needs to reach to power an IoT sensor. The gap between 30mV and 1.5V is a fabrication optimization problem: geometry refinement, surface quality, pillar spacing, cavity depth. White was running 2-week sprint iterations at the time. The 1.5V figure in the PRR 2026 paper reflects the theoretical model's prediction, not necessarily the current bench output.

"A peer-reviewed physics paper claims a nanoscale device produces continuous current from quantum vacuum fluctuations. The result has not been independently replicated. Here's what we know and what remains unproven." — This framing is accurate, fair, and does not overstate or dismiss.
For Investors & Policy Analysts
Roadmap to Commercialization
What milestones must be achieved before ZPE harvesting becomes a commercial technology? This is an honest technology readiness level (TRL) assessment.
TRL 1–2
Basic Physics Demonstrated ✓ (Done)
Casimir effect measured. MIM diode quantum tunneling demonstrated. Anomalous current reported by Moddel (2021) and White (2026). Basic physical principle is plausible.
TRL 3
Artifact Elimination — CURRENT GATE
The cryogenic temperature sweep (4K → 300K at zero bias) must be published. Independent replication by a third lab must be completed. This is the current scientific bottleneck. Estimated cost: $50K–$200K. Estimated timeline if funded today: 12–24 months.
TRL 4
Laboratory Proof of Concept
Reproducible device with characterized output across multiple chips, temperatures, and device areas. Scaling law confirmed (current ∝ area). Multiple independent labs reproducing. Estimated: 2–5 years post-TRL-3.
TRL 5–6
Relevant Environment Demonstration
Device operates continuously in a real-world environment (IoT sensor, wearable). Durability, encapsulation, and packaging solved. Foundry-compatible fabrication process established. Estimated: 3–8 years post-TRL-4.
TRL 7–9
Commercial Product
Manufacturable at scale. Unit economics competitive with alternatives. First commercial applications: maintenance-free IoT sensors, remote monitoring. Grid-scale applications would require 8–12 additional orders of magnitude improvement and represent a separate, much longer-horizon milestone.
Investor Reality Check
This technology is at TRL 2–3. The gap between TRL 3 and a commercial product is enormous, expensive, and uncertain. The biggest near-term catalyst is the 4K temperature sweep publication — that result will move the scientific credibility needle more than any other single event. Before that result exists, any commercial timeline is speculation. After it exists (if positive), serious capital will mobilize quickly.
In Plain Terms
ZPE harvesting is where solar cells were in 1954 — the physics works, the first device exists, and commercialization is a real possibility. But it took solar 40 years to become economically competitive. The path is: prove it in a cryostat first, then worry about scale.

The Researcher
Garrett Moddel — The PI Behind the Peer-Reviewed Result
Most ZPE media coverage centres on Harold White's Joe Rogan appearance. The more experimentally rigorous work came first — from a quiet corner of electrical engineering at the University of Colorado Boulder.
Academic Position
Professor, Department of Electrical, Computer, and Energy Engineering (ECEE), University of Colorado Boulder. Director of the Quantum Engineering Lab. Tenured faculty. IEEE Fellow.
Research Focus
20+ years working on quantum vacuum energy transduction, optical rectennas (THz MIM diodes for solar harvesting), and unconventional energy sources. His ZPE work grew directly from his rectenna program — both use the same MIM physics.
Intellectual Honesty
Moddel is careful to distinguish between "current is measured" and "source is confirmed ZPE." His own papers list artifact concerns. He does not claim commercial viability. This epistemic discipline is what makes his work worth engaging.
Key Publications
PRR 2021: Casimir cavity changes MIM conductance at zero bias. 8 artifact tests. ~70 W/m² estimated. Symmetry 2022: Thermodynamic argument that Casimir cavity extraction does not violate 2nd law. Patent 7,379,286: Co-filed with Bernard Haisch, 2001 — the foundational IP.
Funding Sources
NSF ECCS program (THz rectenna), DOE BES (quantum vacuum energy), private foundation grants. No known DARPA or DoD funding for ZPE specifically — his work is funded through conventional academic channels, which strengthens its credibility.
The Missing Collaboration
White's Casimir Inc. chip has not been sent to Moddel for independent characterisation. Moddel's rigour + White's chip would be the ideal experimental pairing. No announcement of this collaboration has been made as of 2026.
In Plain Terms
Moddel is the scientist doing the slow, careful work — controlled experiments, published methods, acknowledged uncertainties. He's not selling anything. If you want to understand the experimental evidence for ZPE harvesting, his papers are the primary source. Google Scholar: search "Moddel Casimir MIM."
Pop Culture vs Physics
Sci-Fi Gets ZPE Wrong (Except These Parts)
Hollywood has been writing ZPE into scripts for 30 years. Here's the accuracy scorecard — which portrayals are closest to real physics, and which invented their own universe.
🦾
Iron Man Arc Reactor
Claim: Miniaturised fusion / zero-point power source in chest cavity. Reality: The arc reactor is never clearly explained as ZPE — it shifts between palladium fusion and "new element" handwaving. Power output (~3 GW implied) is ~80 billion times White's chip. Accuracy: 2/10
🌀
Stargate ZPM (Zero Point Module)
Claim: Device extracts energy from a "self-contained region of subspace." Reality: This is actually the closest sci-fi concept to real Casimir cavity physics — a bounded geometric region with different vacuum mode structure than free space. The writers clearly consulted the physics. Accuracy: 7/10
🚀
The Expanse — Epstein Drive
Claim: Fusion drive, not ZPE — but the show is honest about power constraints. Reality: The Expanse is the most physically honest portrayal of energy limits in sci-fi. No ZPE magic. Power density, thrust, and travel time are internally consistent. Gets the "it's hard" part exactly right. Accuracy on energy physics: 9/10
💠
Avatar — Unobtanium
Claim: Superconducting mineral that generates the floating Hallelujah Mountains. Reality: The levitation is from magnetic fields, not vacuum energy. "Unobtanium" is explicitly a room-temperature superconductor plot device, not ZPE. No connection to Casimir physics. Accuracy: 1/10
⚔️
Star Wars — Kyber Crystals
Claim: Crystals that focus "the Force" to power lightsabers and the Death Star. Reality: Pure fiction with no physics basis. Power requirements for a Death Star beam (~10²⁶ W) exceed the sun's total output. No ZPE mechanism. Included here because 23% of online ZPE searches include Star Wars. Accuracy: 0/10
🪐
Interstellar — Cooper's TARS Data
Claim: Quantum data from inside a black hole transmitted via gravitational anomalies through time. Reality: Kip Thorne consulted on the physics. The tesseract scene correctly depicts quantum information and extra-dimensional space. The energy source is gravity, not ZPE — but the vacuum energy density inside a black hole is handled with genuine care. Accuracy: 6/10
Why It Matters
Sci-fi shapes public expectations. When Iron Man's reactor powers a suit of armour indefinitely, audiences assume real ZPE chips should power cities. White's chip produces 37.5 microwatts. The gap between expectation and reality is where skepticism becomes cynicism — and where this explainer lives.
Consumer Alert
How to Spot a ZPE Scam — FTC Red Flags
The FTC and FDA have both taken action against "zero point energy" products. Real research exists. Real fraud exists. Here is how to tell them apart in under two minutes.
🚩
Red Flag 1: No peer-reviewed citations
Legitimate ZPE research has DOI-linked publications in Physical Review, Symmetry, or similar APS/AIP journals. If a product or company cites only YouTube videos, testimonials, or self-published papers, the science is fabricated.
🚩
Red Flag 2: Claims of "free energy" or perpetual motion
No ZPE device produces more energy than its input indefinitely without an external non-equilibrium source (the Casimir cavity geometry). Any product claiming perpetual motion, overunity, or "self-running" energy is making a claim that violates established physics without the extraordinary evidence required.
🚩
Red Flag 3: "Biofield" / healing / consciousness claims
The FTC has specifically targeted "zero point energy wands," "quantum healing pendants," and "scalar energy devices" sold with health claims. ZPE in physics has no documented interaction mechanism with human biology at the energies and scales involved. These are either fraud or misappropriation of the physics term.
Red Flag 4: Specific power output claims without measurement protocol
A legitimate claim specifies: device area, measurement temperature, bias voltage, measurement instrument (e.g., Keithley 6430), and control tests run. "Produces unlimited energy" or "powers your home" without a measurement protocol is not a physics claim — it's marketing.
✓
What Legitimate ZPE Research Looks Like
Peer-reviewed journal (APS, AIP, Nature group). Named PI with verifiable university affiliation. Explicit artifact control tests. Conservative claims ("current is measured" not "ZPE is confirmed"). Open acknowledgment of replication gap. DOI-linked primary sources. Examples: Moddel PRR 2021, White PRR 2026.

For VCs, Angels & DAOs
10-Point Due Diligence Checklist — ZPE Startups
This technology is at TRL 2–3. Before writing a cheque, run every item on this list. A startup that can answer all ten with primary sources is worth a second meeting.
1
Is there an independent replication?
The single most important gate. If no independent lab (no financial connection to the founders) has reproduced the core measurement, you are pre-TRL-3. That's not automatically disqualifying — but the valuation must reflect it. Ask for the specific lab names and paper DOIs.
Status as of 2026: No independent replication published for either Moddel or White
2
Has the 4K cryogenic test been published?
Sweeping temperature from 300K to 4K at zero bias is the decisive artifact elimination experiment. ZPE signal stays flat; thermoelectric/thermal noise signals go to zero. Ask for the published result. If it hasn't been run, ask why — and what the budget is to run it ($50K–$200K).
3
Is the PI credentialed and at a named institution?
Moddel: tenured professor, ECEE, CU Boulder. White: PhD, 15+ years NASA. Both have verifiable academic/professional histories. Any startup whose science leads are anonymous or lack institutional affiliation warrants additional scrutiny.
4
Is the core claim peer-reviewed?
In a reputable journal with editorial review and referee reports. Physical Review Research, Nature Physics, ACS Nano are appropriate venues. Pre-prints alone (arXiv) are not peer-reviewed — they are preliminary. Both Moddel (2021) and White (2026) have passed peer review at Physical Review Research.
5
What is the current TRL and what does TRL+1 cost?
TRL 2: physics principle observed. TRL 3: lab proof of concept. TRL 4: validated in lab environment. Ask for a specific milestone map with costs. "We need $X million to reach TRL 3" is a fundable ask if X is justified. "We're revolutionising energy" is not a milestone.
6
Is the fabrication method fully disclosed in the publication?
Moddel's PRR 2021 includes detailed fabrication methods: ALD cycles, deposition rates, lithography steps. If a company claims a working device but the fabrication method is fully proprietary and undisclosed, you cannot assess reproducibility or yield prospects.
7
How many artifact control tests were published?
Moddel ran 8 (Seebeck, JN noise, EM pickup, contact potential, photoconductivity, microphonic vibration, work function EMF, same-metal control). A startup claiming ZPE output with fewer than 6 rigorously described artifact tests should be asked to complete the list before funding.
8
What IP protects the core technology?
The foundational patent is Moddel & Haisch US 7,379,286 B2 (2001, expired 2021). New IP must be on specific geometries, fabrication methods, or device architectures that differentiate from the expired patent. Ask for the patent portfolio and freedom-to-operate opinion.
9
Who are the technical advisors?
Named advisors with publication records in relevant fields (quantum vacuum physics, MEMS, nanofabrication, cryogenic measurement). Advisors whose primary credential is "consciousness researcher" or "alternative energy pioneer" are a negative signal.
10
What is the specific first commercial milestone?
The defensible near-term market is maintenance-free IoT sensors (~15–20 billion deployed). If the company's first commercial target is smartphones, grid power, or electric vehicles, the roadmap is not credible at current TRL. Ask for a letter of intent from a sensor manufacturer, not a vision slide.
Investor Reality Check
If a startup cannot answer questions 1, 2, and 4 with primary sources — walk. If they can answer all ten, you are looking at one of the highest-upside pre-TRL-4 investments in materials physics. The risk profile is binary: either ZPE harvesting works at useful scales (market: $10–40B annually in IoT sensor maintenance) or it doesn't (investment: zero). Price accordingly.
For Academic Researchers
Grant Proposal Language — NSF / DOE / ARPA-E
If you're a PhD student or faculty member trying to fund replication or related experiments, here is how to frame ZPE harvesting for different funding bodies — and which programs are most likely to fund it.
NSF — ECCS Program
Electronics, Communications, and Cyber Systems. Best fit for MIM diode fabrication + THz rectification work. Frame as: "quantum vacuum fluctuation transduction via ultrafast MIM tunnel junctions" — not "zero point energy harvesting." The physics is the same; the framing avoids reviewer bias.
Program code: NSF 23-547 (ECCS) · Typical award: $200K–$500K/3yr
NSF — PIRE (International)
Partnerships for International Research and Education. Casimir force measurement expertise is distributed globally (Leiden, KIT, Tokyo). A US–EU collaboration to independently replicate Moddel's result is a textbook PIRE application. Strong emphasis: "independent verification of anomalous quantum vacuum effects."
Budget: up to $5M / 5yr · Requires 3 international partner institutions
DOE — Basic Energy Sciences
Office of Science, BES. Relevant division: Materials Sciences and Engineering. Frame as: "non-equilibrium thermodynamics in nanostructured metal-insulator-metal junctions under quantum vacuum boundary conditions." Strong fits with BES's "Quantum Materials" and "Energy Frontier Research Centers."
Single investigator: $200K–$400K/yr · EFRC: up to $4M/yr
ARPA-E — OPEN Programs
ARPA-E's OPEN solicitation explicitly funds "transformational energy technologies too early for private investment." ZPE harvesting at TRL 3 qualifies if the preliminary data (Moddel 2021) is presented as the basis. ARPA-E reviewers are less conservative than peer reviewers. Frame: "solid-state ambient energy harvester with no moving parts."
Typical: $500K–$3M / 2yr · OPEN solicitation every ~2 years
Sample Abstract Language
"We propose to investigate non-equilibrium current generation in Metal-Insulator-Metal (MIM) tunnel junctions adjacent to nanoscale Casimir cavities, with the goal of determining whether the anomalous current reported by Moddel et al. (PRR 2021) is attributable to quantum vacuum mode asymmetry or to thermal artifact processes. Specifically, we will conduct the first published cryogenic temperature sweep (4K–300K) at zero applied bias, providing a definitive artifact discrimination test. Secondary objectives include fabrication of an integrated Seebeck sensor co-located with the MIM junction for real-time thermoelectric subtraction, and a systematic cavity gap sweep (50–500nm) to test the predicted d⁻⁴ current scaling."
Reviewer Framing Tip
Never use "free energy," "perpetual motion," or "zero point energy harvesting" in a proposal abstract — these phrases trigger automatic skepticism in conservative reviewers. Use: "quantum vacuum fluctuation rectification," "Casimir cavity non-equilibrium transduction," or "anomalous current in Casimir-adjacent MIM diodes." The physics is identical; the framing is what gets funded.
Defense & Intelligence
DARPA, DoD, and ZPE — What's Actually Declassified
Government interest in zero point energy is not a conspiracy theory. It is a documented, FOIA-accessible part of US defense research history. Here's what is confirmed, what is speculative, and what remains classified.
✓
DIA FOIA Document — "Traversable Wormholes, Stargates, and Negative Energy" (2019)
Released under FOIA as part of the AATIP (Advanced Aerospace Threat Identification Program) declassification. Document is publicly available via theblackvault.com and documentcloud.org. It explicitly lists zero point energy extraction as a potential advanced technology of interest. The report is a literature review, not an experimental result — but its existence confirms DoD was funding research into ZPE feasibility.
Authors: Eric Davis, William Puthoff — both published physicists · Classification: UNCLASSIFIED as of 2019
✓
Harold White's NASA Eagleworks → USSPACECOM Pipeline
White led NASA Eagleworks Advanced Propulsion at JSC (2011–2023). Eagleworks is a DARPA-connected lab — its warp drive and EmDrive research received indirect DoD interest through the AATIP program. White's current work at Casimir Inc. follows the same physics pipeline: exotic propulsion → vacuum energy → energy harvesting.
Public record: NASA Technical Reports Server; AATIP Congressional disclosure 2017
✓
Office of Naval Research — Casimir Force Research
ONR has funded Casimir force measurement research at multiple universities as part of its nanotechnology and MEMS programs. The motivation: Casimir stiction is a critical engineering problem in MEMS devices used in Navy systems. This funding is for measurement, not harvesting — but it built the experimental infrastructure that ZPE harvesting research uses.
ONR program: N00014 series grants; verifiable via grants.gov and USASpending.gov
✓
AATIP → AOIMSG → AARO Program Lineage
The government UAP (Unidentified Aerial Phenomena) investigation program has passed through three names: AATIP (2007–2012), AOIMSG (2021–2022), AARO (2022–present). Each successive program maintained interest in "novel propulsion and energy" as part of its mandate. ZPE is referenced in the underlying research contract (BAASS, Bigelow Aerospace). No classified results on ZPE have been declassified as of 2026.
?
JASON Group Reviews — Unknown Status
JASON is an independent group of elite scientists advising the DoD on technical matters. Their reports are often classified for years. JASON has reviewed exotic energy and propulsion topics in the past. Whether they have reviewed ZPE harvesting specifically is unknown — no JASON report on this topic has been declassified. JASON reports on related topics (inertia, vacuum fields) have surfaced under FOIA, suggesting broader interest.
Speculative — not confirmed by public record
The Bottom Line on Government Interest
DoD interest in ZPE is real and documented — primarily through AATIP literature reviews and ONR Casimir force engineering. This is not evidence the technology works; it is evidence that credentialed physicists within the defense establishment considered it worth reviewing. The absence of a classified breakthrough is consistent with the technology still being at TRL 2–3: the public research is where the action is.
Quick Reference
ZPE in 60 Seconds — The Complete Cheat Sheet
Everything on this page distilled to its essential facts. Share this section if someone asks you to explain ZPE in plain English.
What Is Zero Point Energy?
Heisenberg's uncertainty principle means energy can never be exactly zero. Even at absolute zero temperature, every quantum system keeps a minimum baseline energy — that's zero point energy. It is real and measured. The Casimir effect (a tiny attractive force between two uncharged plates in a vacuum) is the direct proof. Measured by Lamoreaux in 1997 to 5% precision.
Harold White's Chip
Former NASA physicist Harold White founded Casimir Inc. and developed a 5×5mm chip that reportedly outputs 1.5V and 25µA (~37.5 microwatts). He described it on Joe Rogan #2318 (May 2025) as "a solar panel that works in the dark." Not independently verified.
Garrett Moddel's Experiments
Garrett Moddel, professor at CU Boulder, published peer-reviewed results in Physical Review Research (2021) showing a Casimir-cavity-adjacent MIM diode produces continuous current at zero applied voltage. He ran 8 artifact control tests. Estimated power density: ~70 W/m². No independent lab has replicated this result.
Why DIY Coil Circuits Don't Work
ZPE peaks at 7+ THz. Coil circuits operate at kHz — ten billion times too slow. Only a MIM diode with a 2nm insulator can interact with ZPE via quantum tunneling in ~1 femtosecond. No coil, no antenna, no circuit you can buy parts for will ever measure a ZPE signal.
Current Research Status
✓ Confirmed
ZPE exists and is measurable (Casimir effect). Devices produce current.
? Unverified
Whether the source is ZPE or a thermoelectric artifact (Seebeck effect).
