Their Claims
Bruce DePalma's contributions to UAP-relevant physics center on two related discoveries: the Spinning Ball Experiment and the N-Machine.
The Spinning Ball Experiment
In the early 1970s, DePalma conducted a deceptively simple experiment that produced anomalous results. He launched two identical steel balls into the air simultaneously using the same catapult mechanism — one ball spinning at 27,000 RPM, the other not spinning. Using strobe photography techniques he had learned from his mentor Harold "Doc" Edgerton at MIT, he photographed the trajectories.
The spinning ball consistently traveled higher and fell faster than the non-spinning ball — results that should not occur under Newtonian mechanics, where rotation should have no effect on gravitational freefall. DePalma published these results in the British Scientific Research Association Journal in 1976.
DePalma interpreted these results as evidence that rotation alters an object's interaction with gravitational and inertial fields. He proposed that a spinning object partially "decouples" from the inertial frame, reducing its effective gravitational mass. If correct, this would represent a fundamental discovery about the relationship between angular momentum, inertia, and gravity — precisely the kind of physics that could explain UAP flight characteristics.
The N-Machine
Building on his understanding of rotation's effects on inertia, DePalma developed the N-Machine, a type of homopolar generator based on Michael Faraday's 1831 Faraday disc. The device consisted of a magnetized conducting disc spinning on its axis, with electrical contacts at the center and rim.
DePalma claimed that the N-Machine could produce five times the electrical energy required to rotate it — an over-unity ratio that, if true, would violate the established laws of thermodynamics. He believed the excess energy came from the space itself — that the spinning magnetized disc was extracting energy directly from what he called "the Primordial Energy Field" (conceptually equivalent to zero-point energy or the quantum vacuum).
DePalma argued that the conventional understanding of homopolar generators accounted for only the electromagnetic induction component, missing the additional energy contributed by the rotation-inertia coupling he had identified in his Spinning Ball Experiment.
Key Quotes
"In my free energy generator or the N-Machine, the electrical current is sucked from the space itself with the help of the magnets, and not due to the action of the magnet/conductor rotation, as may be assumed by conventional physics." — Bruce DePalma, describing the N-Machine's claimed operating principle
"The spinning ball experiment is the most fundamental experiment in physics — it tells us that rotation changes the way objects interact with gravity." — Bruce DePalma, attributed from lectures
"All of our ideas about energy are based on the idea that it can neither be created nor destroyed. But what if the vacuum of space is not empty — what if it contains energy that a properly designed machine can access?" — Bruce DePalma, from "On the Possibility of Extraction of Electrical Energy Directly from Space" (1990)

- Credentials: Harvard BA in electrical engineering (1958), 15 years teaching physics at MIT under Doc Edgerton, senior scientist at Polaroid Corporation under Edwin H. Land — not a fringe inventor but a credentialed mainstream scientist

The Physics
Homopolar Generator Basics
A homopolar generator (also called a unipolar generator or Faraday disc) is the simplest type of electrical generator. A conducting disc spins in a magnetic field, and a voltage is produced between the center and the rim through electromagnetic induction. Faraday demonstrated the first one in 1831.
The device has a curious property known as the Faraday paradox: the exact mechanism by which the EMF is generated — whether it is the disc's rotation relative to the magnet or relative to space — has been debated for nearly two centuries. In the N-Machine, the magnet and the disc are one and the same object (a magnetized conducting disc), making the question of the "seat of EMF" even more complex.
DePalma's Proposed Mechanism
DePalma proposed that:
- Rotation partially decouples matter from the inertial frame — as demonstrated (he argued) by the Spinning Ball Experiment
- A spinning magnetized conductor interacts with the vacuum energy field — the rotation creates a condition where energy from the quantum vacuum (or "Primordial Energy Field") can flow into the electrical circuit
- The excess energy is not created but extracted — the device does not violate conservation of energy if one accounts for the vacuum energy reservoir as an external energy source
- Conventional physics models miss this contribution because they do not account for the rotation-inertia-vacuum coupling
Relevance to UAP Physics
DePalma's work connects to UAP physics in several ways:
- Rotation and inertia: If rotation can alter inertial properties (as the Spinning Ball Experiment suggests), this connects directly to the inertial mass reduction described in Salvatore Pais's Navy patents and Bob Lazar's descriptions of gravity amplification
- Vacuum energy extraction: DePalma's claim that the N-Machine extracts energy from the vacuum parallels the Zero Point Energy thesis — the central energy source proposed for UAP propulsion
- Rotating superconductors: Ning Li's theoretical work on generating gravitomagnetic fields from rotating superconductors addresses the same rotation-gravity coupling from a more rigorous theoretical framework
Where They've Said It
- Spinning Ball Experiment results — British Scientific Research Association Journal, 1976
- "On the Possibility of Extraction of Electrical Energy Directly from Space" — 1990
- Numerous lectures and conference presentations on free energy and the N-Machine, 1970s-1997
- Published correspondence and technical notes archived at brucedepalma.com and depalma.pairsite.com
- Demonstrations and tests of N-Machine devices, including the final New Zealand test (posthumous, 1997)
The Counterargument
- The Spinning Ball Experiment has not been independently replicated under rigorous peer-reviewed conditions; air resistance differences between spinning and non-spinning projectiles could account for some or all of the observed trajectory differences
- The N-Machine's claimed over-unity performance was never demonstrated in a controlled, peer-reviewed test; the single post-death test in New Zealand failed, with most output energy lost as heat
- Mainstream physics holds that homopolar generators are fully explained by conventional electromagnetic induction and that no over-unity performance is possible
- The Faraday paradox, while a genuine historical curiosity in physics, has been resolved by most physicists using relativistic electrodynamics — it does not require invoking vacuum energy
- DePalma left the United States and relocated to New Zealand in the early 1990s, which could indicate either escape from suppression or recognition that his devices did not perform as claimed in the US scientific environment
- Paramahamsa Tewari's reported positive results from India were never published in peer-reviewed journals and have not been independently verified
- The claim of five-times over-unity has never been confirmed by any independent measurement team using calibrated instruments
