Hendershot Generator pdf - The fuel-less generator

This is the story of another inventor who died before his ideas were completely understood or accepted by scientists and society. For more than 30 years Lester Hendershot worked on an over-unity device that was thought to be tapping into a magnetic force field. Interestingly, Hendershot seemed to be the only person capable of activating it, but was "unable to provide a satisfactory scientific explanation" for why his creation worked. Nevertheless, the fuel-less generator was demonstrated many times from 1928 to 1960, and its validity was attested to by several witnesses including Charles Lindbergh. A demonstration was even conducted before the U.S. press in which the device passed all assessment tests.

Newspaper clippings indicate its efficacy but according to Bill Beaty of KeelyNet, Hendershot "ran into political difficulties in promoting his device, attempted to take his business to Mexico, and finally faded into obscurity."  In 1961, he planned a final attempt to reveal his generator to top electronic engineering groups down to the precise construction and operation. Evaluation of the source of power for Lester Hendershot's device was never determined because he died on April 26th of that year. Fortunately, three years before his death, he allowed Ed Skilling to assist him in reconstructing his device, running it successfully. Skilling later wrote a magazine article in which Hendershot's construction specifications were explained. Around the same time, the inventor involved a man named Arthur C. Aho in many of his experiments, "operating and evaluating certain devices which generated electricity in usable form, but with no loss to any of its parts and without the use of fuel of any type." This private research went on for 2½ years and provided us with many interesting applications and interpretations.

There were many variations of the generator that all seemed to work — producing up to 300 watts. Hendershot's creations were made with a basket-weave coil containing inner cylindrical capacitors, a vibrator circuit, and solenoid coils separated from a magnet by a soft iron bar between two transformers. Many pieces of his generator were obtained from telephone and radio parts of the time. Upon assembling the device, Hendershot would spend anywhere from ten minutes to several hours connecting an insulated wire to different terminals until a buzz from the magnet-solenoid combination and a glow from the light bulb output load would signal energy production. In order to get a steady buzz and the brightest light, he would adjust the gap between the solenoid coils and magnet. This device could power televisions, radios, or small motors when it worked, but often it did not work at all, which remained inexplicable.
According to Aho, while other researchers constructed slightly different devices, they "all had two things in common, they generated electricity without the use of fuel or material loss to any of its parts, and there was an operator who used individualized methods to trigger the device into operation."
While working with the inventor, Aho decided to construct five devices so that he could see them work. After painstakingly building the first one and having it tested by Hendershot himself, the success of the generator showed him that "limits based on studies of exchange of energy and/or quantum mechanics did not indeed exist." Aho still has the last generator constructed, but it "is only so much material without the influence of Lester Hendershot—whatever that may be—and the device does not operate."  hendershot generator pdf

Mark Hendershot, Lester's son, is continuing his father's research. He believes "that once again the theory and working proof can be presented to a world which may now be available hendershot generator pdf
