Lester Hendershot (1899-1960) was the Inventor of the so-called Fuelless Motor (1928).

In the 1920's Lester Hendershot was working on a new type of aviation

compass. He stumbled across a method of generating energy. His "Hendershot

magnetic motor" drew attention of the press and attracted big name investors as

Charles Lindberg. He got into political trouble promoting

his device and consequently tried to take his business to Mexico. He is reported to have

accepted an offer he couldn't refuse being paid never to work on

his device again.

In 1961 Dr. Ed Skilling, from Columbia University, successfully built and tested a Hendershot free energy device, out of which he got 300 watts. Skilling had been associated with Hendershot and learned of the device through him. The generator was self-resonant at 500 kHz.

The Machine


Not claiming his device to be a perpetuum mobile explained he that it was tapping the earth's magnetic field and rotation as its energy source.

The Hendershot Device concerns a self-running oscillator. There are a pair

of large air-core coils positioned in a "basket weave" pattern, hand-made cylindrical

capacitors inside the coils, several high-value capacitors, a couple of

standard transformers and a permanent-magnet "buzzer" for a regulator.

The two large coils are tuned to resonate with each other. The device generated

an AC output and was capable of lighting a bank of lightbulbs.


Oldest Son

"As the oldest son of Lester J Hendershot I witnessed the works of my father." (Posted in 2008?)


Only Hendershot could adjust his device for successful operation. Hendershot's son attempted to reproduce his father's discovery, but no success has been reported.

Quotes about Hendershot:

"In 1960, Hendershot's device (now called a 'magnatronic generator') was researched by the U.S. Navy's Office of Naval Research. The generator was reported to have lit a 100-watt lamp by 'induced radio frequency energy'. The project ended when Hendershot committed suicide." from:Tremendous new Power Soon to be released' by Doug Yurchey (2002)

"Two historical events are worth including here regarding possible suppression and inability to commercialize Free Energy devices. These are the Over-Unity Device of T. Henry Moray (Resines, 1988), and the Hendershot Motor (Brown, 1988). Both of these devices were publicly demonstrated to the US press in the 1930s, and carefully conducted tests were made to assess these devices. From the newspaper reports and clippings, it appears that both devices passed all tests, only to fall into oblivion. What exactly happened to the devices, their inventors, and the technology is not known. It also appears that the secrets of the devices died with their inventors." From A Review Of Zero Point Energy And Free Energy Theory, Progress, And Devices by Patrick C. Baily. (1992)

"Hendershot ran into political difficulties in promoting his device, attempted to take his business to Mexico, and finally faded into obscurity." Bill Beaty of KeelyNet.
