E-Cat Power: Electricity from the Quantum Vacuum, On Pre‑Order Since 2023

Leonardo Corporation's whitepaper promises 24/7 electricity from Zero-Point Energy. We read all 20 pages — the specs, the ChatGPT sustainability table, the Renault Twizy on a go-kart track — so you can weigh the evidence yourself.

tl;dr
  • The NGU Power Cell is a 60 mm plastic disc claiming to extract 10W of DC electricity from the quantum vacuum — perpetually, with no fuel.
  • Its inner design is proprietary. The science is not accepted by mainstream physics. No independent verification has been published.
  • The whitepaper's sustainability ratings were generated by asking ChatGPT to score the product using Leonardo's own unverified data. E-Cat scored 5/5 in every category.
  • One public demo in 2024: a Renault Twizy drove for 6 hours on a racetrack with its SoC rising 15 percentage points.
  • Mass production begins when pre-orders reach 10 million cells. Pre-orders are non-binding and require no payment.

Andrea Rossi has been "almost ready" since 1997. His latest document — a polished, 20-page whitepaper from Leonardo Corporation, revised as recently as December 2025 — claims the wait is finally over. The NGU Power Cell, a white plastic disc about the size of a hockey puck, allegedly harvests electricity directly from the quantum vacuum. No fuel. No emissions. 24/7, forever. Thirty-five dollars per 10-watt cell.

If true, this is the most important invention in human history — bigger than fire, bigger than the transistor. If not, it joins a long and distinguished line of LENR-adjacent announcements that generated significantly more enthusiasm than watts.

We read every page. Here's what we found.

Chapter 1 — History & Science

The Science: Harvesting the Quantum Vacuum

The theoretical foundation is Zero-Point Energy (ZPE) — the lowest possible energy state of a quantum mechanical system. ZPE is real: it has measurable effects (the Casimir effect, Lamb shift) and is a well-documented phenomenon in quantum field theory. Documented

What mainstream physics does not accept is that ZPE can be extracted as usable work at useful scales. The whitepaper itself acknowledges this directly: "The theory behind E-Cat Power is still not generally accepted by science." Disputed by Physics

Rossi's theoretical model is laid out in his 2019 paper, E-Cat SK and Long-Range Particle Interactions, which draws on the work of Tesla, Dirac, Puthoff, and others to propose an electron-based mechanism for extracting electromagnetic energy from ZPE. The paper has accumulated more than 170,000 reads. Documented It has zero peer-reviewed independent replications. ?Not Independently Verified

A note on sourcing: The whitepaper was partially co-authored with GPT-4o. This is disclosed in the document. The sustainability ratings in Chapter 3 were generated by asking ChatGPT to score the product using Leonardo's own unverified data as the prompt input. The document describes this as "a potential rating." That is one word for it.
Chapter — Renewable Energy Challenge

Context: Where the World Gets Its Electricity (2022)

The whitepaper situates E-Cat Power within the real energy transition challenge — citing IEA data. The numbers are accurate. Only 29% of global electricity came from renewable sources in 2022. Coal and gas still supply 58%.

Chapter 3 — Sustainability

The Sustainability Ratings (Source: ChatGPT)

Rather than awaiting independent scientific evaluation, Leonardo used GPT-4o to generate a 1–5 rating of E-Cat Power vs. other renewables. The input was Leonardo's own unverified performance data. The whitepaper includes a disclaimer noting the ratings are "subjective and still provisional." Amber rows indicate self-reported data. Click headers to sort.

Chapter 7 — First Public Demonstration

The Demo: Latina, September 27, 2024

The first public demonstration used two Renault Twizy 80 electric vehicles — the lightest, slowest, and most modest EV sold in Europe. One carried a 3kW NGU Power Generator. Both drove simultaneously on a 0.6 km racetrack in Latina, Italy.

The standard vehicle (EV2) ran until the battery died. The E-Cat vehicle (EV1) drove for six hours, ending with a higher battery charge than it started with.

VehicleStart SoCEnd TimeDistanceEnd SoCSoC Δ
EV1 — E-Cat (3kW NGU)68%380 min201 km83%+15%
EV2 — Standard Twizy98%140 min74 km0%−98%
The numbers, checked: EV1 covered 201 km in 380 minutes (~31.7 km/h average). The Twizy 80 has a 6.1 kWh battery. At low racetrack speeds (~30 km/h), consumption is approximately 45 Wh/km = 9 kWh total. The SoC rose 15% = 0.9 kWh net gain. That implies the generator produced ~10 kWh in 6.3 hours ≈ 1.6 kW average output from a 3 kW rated unit. The arithmetic is internally consistent — if the generator is real.
What was not present: The inspection of both vehicles was conducted by an "EV specialist" at the event — not an independent third party. The interior design of the NGU generator remains proprietary. No independent verification of the demonstration has been published. ?Not Independently Verified
Chapter 5 — Economy & Costs

The Economics: LCOE Below $0.10 / kWh

Leonardo uses the standard LCOE (Levelized Cost of Electricity) metric. At $35/cell, a 3 kW residential system requires ~300 cells = $10,500 in cells alone. The whitepaper prices the full initial system at $3,700/kW = $11,100 for 3 kW, suggesting tight integration costs. Toggle between scenarios below.

Chapter 6 — Implementation

The Business Model: A Pre-Order With No Orders

Since March 2023, Leonardo Corporation has accepted pre-orders at ecathenewfire.com. Pre-orders are non-binding and require no payment. Production begins when the equivalent of 10 million 10W NGU Power Cells are pre-ordered.

Twelve million cells at $35 each would represent $350 million in theoretical demand — though since no money changes hands, the milestone is structurally a petition rather than a commercial commitment. Leonardo has not disclosed current pre-order figures.

The whitepaper notes that the manufacturing system is "already prepared," including in-house production of key components and a strategic outsourcing network. The company is waiting only for demand to be demonstrated before flipping the switch.

This is a notable structure. The technology remains unverified because it hasn't shipped. It won't ship until pre-orders are met. Independent verification "will obviously be necessary" — the whitepaper's own words — but is scheduled to happen after production begins. The sequence is: believe → pre-order → produce → verify. The usual order is the reverse.

Editorial Verdict

Our Assessment

The E-Cat Power whitepaper is, by the standards of the genre, a good document. It is clearly written, internally consistent, and — to its credit — forthright about its own limitations. It does not hide the fact that the science is disputed, the technology unverified, and the business model contingent on a threshold that has not been reached. These admissions are buried in disclaimers, but they are there.

What the whitepaper cannot offer is the one thing that would settle all questions: a functioning unit in independent hands. The inner design is proprietary after 27 years. The demonstration used the company's own equipment, inspected by event-appointed specialists, on a private track, with no published raw data. The sustainability scores were generated by a language model that was not designed to be adversarial.

The LENR community has seen extraordinary claims before — some of which turned out to have real anomalies worth investigating, most of which did not. The E-Cat's journey from 1997 cold-fusion replication attempt to 2025 Zero-Point Energy commercial pre-order has been consistent in two respects: the energy output has always been impressive, and the independent verification has always been imminent.

If this device does what it claims, it is the most consequential technology in human history. That is precisely why the bar for evidence should be proportionally high — and why we will be watching, carefully, for independent data.
