“Fuelless Motor Impresses Experts” 

W.B. Stout Says, Invention Works Uncannily — Washington Thinks It’s Important ~ Built On A Radio Principle ~ Armature Winding New — Invention Inspired By Young Son — Lindbergh Flies Here

Detroit, Mich, Feb. 25 — W.B. Stout, head of the Stout Air Lines and designer of the all-metal tri-motored Ford Monoplane, declared here today that he had seen what he characterized as an “impressive” demonstration of the Hendershot fuelless motor two weeks ago in Pittsburgh.

Lester J. Hendershot, the inventor, and his associate. D. Barr Peat, who is manager of the Bettis Field at McKeesport, demonstrated the motor secretly yesterday in a hangar at Selfridge Field. This block test was witnessed by Major Thomas G. Lanspier, Clonel Charles A. Lindbergh and others.

It was explained today that the model used in the demonstration was a much smaller machine than an actual working motor capable of developing enough power to lift and propel an airplane. Its designers claim for it that it runs on an electromagnetic principle, bywhich it draws its force directly from the earth’s field, and through the properties within the motor itself transforms these electric currents into power tha can be delivered efficiently at a propeller shaft.

Calls Demonstration Uncanny 

“The demonstration was very impressive”, Mr. Stout said. “It was actually uncanny. I would like very much to see how a large model designed to develop power enough to lift an airplane would operate”.

Mr. Stout said the model he saw was about the size of the tiny motors used in vacuum cleaners.

“I was told that the revolutionary feature was a hereto unknown manner of winding the armature”, Mr. Stout continued. “Hendershot said he had succeeded in winding it in such a way that it draws energy directly from electrical currents which exist constantly in the air or in the ground. Such sources of cheap and inexhaustible power, of course, never have been reached before. The small model appeared to operate exactly as Hendershot explained that it did”.

Neither Colonel Lindbergh nor Major Lanphier would express themselves at length on the test they witnessed yesterday. Major Lanphier admitted, however, that they were experimenting with it and referred all questions to Hendershot.

“He is the only one who knows all about it”, the Major said. “Lindbergh has nothing to do with it, although he saw it”.

William B. Mayo, chief engineer for the Ford Motor Company, was in conference with Major Lanphier, Hendershot and Peat at Major Lanphier’s quarters today.

“Invention Result Of Dream” 

Hendershot Made First Fuelless Motor For His Son’s Toy Plane 

The invention of the fuelless motor, tested at Detroit, was the result of a dream by its inventor, Lester Jennings Hendershot, who lives on “the street back of the railroad” in this town of about 3,000 inhabitants, 15 miles from Pittsburgh.

Although Hendershot was on his way from Selfridge Field today and is not expected home until tomorrow, his wife told of his conception of the machine and how the miniature model was constructed from the parts of a worn out radio which had been given to the inventor by his uncle.

Several years ago the vision of a machine which would operate from “earth currents” came to Hendershot in a dream, according to his wife, but it was not until last November that he actually started working on it.

His 4-year old boy had built a small airplane at that time and was considerably chagrined because it would not operate. The father was disturbed too, so he told his son he would build an airplane which would work. The result of that was the fuelless machine.

First Model Worked Toy Plane 

When the miniature motor model had been constructed, Hendershot built a small airplane and placed the machine in it. A switch was turned and immediately the propeller began to move. The machie was not connected to any electrical current, but was running on is own accord from “earth currents”.

For several weeks the little motor and the airplane rested upon a small table in the living room of the Hendershot home, which faces an unpaved street near the railroad tracks. One day D. Barr Peat of Bettis Field, the air mail port near McKeesport, Pa., visited the Hendershot home to see the model.

He immediately became enthusiastic and a few weeks later he and Hendershot were at Selfridge Field where permission was been granted to build a model large enough to operate an airplane.

Hendershot, who is only 29 years old, was born in Hyndmann, Pa. His schooling has not been extensive, although he spent a few months several years ago at Cornell University, where he took a few courses in mechanics. He has not been employed at any particular task and has been known as a “freelance” worker. He has been a fireman and an engineer on the railroad, has worked in the mills near Pittsburgh, has inspected concrete and done electrical work. During the war he was a bugler with a machine gun company, but did not get overseas.

Still Wants To See “How They Work” 

According to his mother, he has always been interested in mechanics and when a child he would insist upon taking his playthings apart.

And that desire has not escaped him a man, for even now he takes his own son’s playthings apart to “see how they work”.

It required only a few weeks for him to construct the miniature model of his fuelless motor, although he worked day and night during that time. He had a crude workbench in the cellar of his home, which was placed near the furnace, where it was warm. Early in the morning he would be there, tinkering about, and late at night he still could be found there.

Hendershot’s idea was that the earth currents which make the aurora borealis in the skies could be harnessed by man and made to produce power that would operate an engine.

The youthful inventor has no other inventions to his credit.

“Works On Principle Of Compass” 

Lester J. Hendershot first came to Bettis airplane field in McKeesport between two and three years ago, and soon afterward brought one of his motor models to the officers of the field for inspection.

The fuelless motor works somewhat on the principle of a compass, and the original model would always operate when pointing north or south, as does the compass, but would not move when pointed east or west.

Young Hendershot worked nearly two years to overcome this defect, and finally he brought a motor to the Bettis field that appeared to be working perfectly. This motor was installed in a small model airplane and the plane flew, but owing to the failure to rig it properly, it crashed to the ground during on of the experiments.

Constantly improving the motor, Hendershot finally interested D. Barr Peat, manager of the Bettis Field, in his invention.

After a short time several capitalist were interested, and a few weeks ago the motor was taken to Detroit by Hendershot and Peat for an exhibition.

While no person at the field was in position to say authoritatively, it was stated that the capitalists who become interested in the Hendershot motor have about completed their arrangements for the purchase of the invention, or for controlling its production.

The fuelless motor, it is said, appears to have tremendous power and easily made between 1500 and 2000 revolutions per minute on several occasions while being tested at the field. Pilots and mechanics believe it to be the greatest invention of the age, and all appear sure it will be a practical success as an airship motor.

It was stated at the field that the inspection of the motor by Colonel Lindbergh was made in the interests of the capitalists who were arranging to purchase the invention.

New York Times (February 27, 1928):

“Fuelless Motor Is A Generator” 

The Hendershot “Fuelless motor” is not a motor at all but a generator, according to Major Thomas G. lanphier, commandant at Selfridge Field, Mich., where he with Lester J. Hendershot, the inventor, and D. Barr Peat, have been quietly working on an experimental model.

Major Lanphier said he first became interested in the Hendershot electrical machine several weeks ago through Peat; that in common with others he thought at first it was more or less “bunk” but after seeing it work he became interested.

“I saw the first model which Hendershot built hooked up to a small electric motor of the type used to operate a sewing machine. It not only ran the motor but it burned it out”, Major Lanphier said.

Why this generator acts as it does, where the energy comes from that transforms it into power, Major Lanphier was not prepared to say beyond quoting Hendershot. It is the inventor’s theory that his machine draws its energy from the earth’s magnetic field. While unwilling to describe it in detail until pending patents have been received, Major Lanphier told a little about it. The first model consisted of a ring magnet less than three inches in diameter. Around the magnet were coils rigged as only Hendershot knows how to rig them, and another set of coils pass through the center of the ring.

“With this contrivance we burned out the sewing machine motor and we also kept a 6 watt lamp going with it for 26 hours”, he said.

The larger model which has not yet been hooked to a motor that will deliver power to a crankshaft, Major Lanphier himself helped build.

“We put it together out of stuff we picked up at the field and with it we lighted two 110 watt lamps”, Major Lanphier said. “I think that we have got enough electricity in this second model to kill a man”.

The second model is built around a ring magnet, the outside diameter of which is seven inches and the inside diameter six inches.

It was suggested that perhaps the Hendershot engine was “stealing” power from some big radio broadcasting station.

“We thought of that”, Lanphier said, “but we ran it for 26 hours when stations were going and when they were not and we got the same results”.

New York Times ( November 12, 1928 ):

“May Seek Motor Patent” 

M. C. Kelly to Ask Five Scientists to Test Hendershot Device

Representative M. Clyde Kelly of Pennsylvania, it became known here today, plans to seek a Congressional patent for the “fuelless” motor of Lester J. Hendershot of West Elizabeth, Pa., if five scientists approve the invention as practical. A Congressional patent gives the patentee full protection for 17 years.

Hendershot’s invention, which he describes as a “magnetic induction” motor, was first announced in March. At that time in some quarters it was regarded with skepticism.

The motor, according to its inventor, is without visible means of power. It obtains its initial impulse, Hendershot maintains, from a precharged magnetic core, and its secondary and greatest power impulse by magnetic induction from the earth.

Hendershot today said several of his motors had been built here, and that one, which developed 60 horsepower, had been in operation for two weeks without recharging the magnetic

“Explains Magnet In Fuelless Motor” 

Hendershot Says Shifting Its Field To east And West Causes Rotary Motion ~ Winding Of Magnet Secret ~Inventor Asserts Engine Weighs But 4 Ounces Per Horsepower

Mildly indignant because the manner in which his fuelless motor gains its power had been misrepresented in dispatches from Detroit and Washington, Lester J. Hendershot today stated there was nothing mysterious about his motor, that the force that energizes it is the “same force that pulls the needle of the compass, and there is nothing mysterious about that”.

The fuelless motor was not his objective, he explained, at the time he began his experiments some three years ago, when he first became interested in aviation.

“I soon learned that the ultimate development o aviation depended upon the discovery or invention of an absolutely true and reliable compass”, he explained. “The ordinary magnetic compass does not point to the true north — it points to the magnetic north, and varies from the true north to a different extent at almost every point on the earth’s surface.

“There is another compass, the magnetic induction compass, that indicates true north. But it must be set before each flight, and is not always reliable.

“I found that with a pre-magnetized core I could set up a magnetic field that would indicate true north, but I didn’t know just how to utilize that in the compass I set out to find.

“In continuing my experiments, I learned that by cutting the same line of magnetic force north and south, I had an indicator of the true north, and that by cutting the magnetic field east and west, I could develop a rotary motion.



Generator & Motor



From the Archives of Lester J. Hendershot


Mark M. Hendershot


My name is Mark Hendershot, Lester J. Hendershot was my Father.

Lester was an inventor and in his many attempts at producing practical items, he had a moderate success a few times with electronic toys, and had sold some of his ideas to small manufacturers. His biggest idea, however, was so revolutionary that it embarrassed the nation’s top scientists be-cause they couldn’t explain it, and if it could be perfected, it would possibly eliminate the need for public electric utilities in many instances, and it would completely change most of our present concepts of motivation.

His earlier invention was called a “motor” by the newspapers, but it was actually a generator which was powered by the magnetic field of the earth. His later models created enough electricity to simultaneously light a 120 volt light bulb and a table model radio. I witnessed it furnishing the power to run a television set and a sewing machine for hours at a time in our living room.

It was in 1927 and 1928 that my Father began to think seriously about this “fuel-less” generator. He had taken up flying in 1925 and he soon realized that the ultimate development of aviation would be greatly enhanced by the creation of an absolutely true and reliable compass, and his first efforts were to produce such an instrument.

He theorized that the magnetic compass did not point to true north and varies from true north to a different extent at almost every point on the earth’s surface. Also, the induction compass has to be set before each flight and at that time was not always reliable. He claimed that with a pre-magnetized core he could set up a magnetized field that would indicate the true north, but he didn’t know just how to utilize that in the compass he had set out to develop.

In continuing his experiments, he found that by cutting the same line of magnetic force north and south, he had an indicator of the true north and that by cutting the magnetic field east and west, he could develop a rotary motion.

With this principle in mind, he switched his plans and began working on a motor which utilized this magnetic power. He built one that would rotate at a constant speed, a speed pre-determined when the motor was built. It could be built for a desired speed, he said, and he felt that a reli-able constant speed motor was one of the greatest needs in aviation at that time. The one he built developed 1,800 revolutions per minute.

In the following years, he realized that the idea of a magnetically powered motor was not as practical as a magnetically-powered generator, so his later work was directed toward the generator.

To avoid confusion, it should be pointed out that the early experiments began on a magnetically-powered motor, and later a generator.

The first significant experiments on the motor version were held at Selfridge Field, Detroit, under the direction of Major Thomas G. Lanphier, commandant of the field and leader of the First Pursuit Group.

The device demonstrated at Selfridge was a small model of what he hoped would be developed into an airplane engine [powered by earth’s magnetic field]. Quotes in the newspapers referred to top aeronautical brass of the day and their impressions of what they saw.

One such report was credited to William B. Stout, president of the Stout Air Service, Inc., and designer of the all-metal type plane used by the Ford Motor Company. Stout’s comments were: “The demonstration was very impressive. It was actually uncanny. I would like very much to see a large model, designed to develop enough power to lift an airplane.”

Major Lanphier’s comments to reporters after the demonstrations were:

“The whole thing is so mysterious and startling that it has the appearance of being a fake.”

“I was extremely skeptical when I saw the first model,” he continued, “but I helped to build the second one and witnessed the winding of the magnet. I am sure there was nothing phony about it.”

My Father had first shown the military brass how his model worked, then he supervised army technicians in building their own model, which worked perfectly. Major Lanphier said that the electrical men to whom they had shown the motor “… laughed at the way we wired it up and said it wouldn’t work. Then it DID work.”

It was the Selfridge Field experiment which touched off the series of stories in the national press. Stories with blaring headlines in such papers as the Detroit Free Press, Detroit News, Detroit Times, Pittsburgh papers, The New York Times, and many others. Most of them tagged the instrument demonstrated at Selfridge the “miracle motor,” and there were pictures of Major Lanphier and Col. Lindbergh, my Father and the motor.

Anything in the news during that period which could be connected with Lindbergh was front page whether he had an active interest, or just happened to be in the area at the time.

Headlines in the various papers read, “Gasless Motor Tested for Lindy,” “Lindy Inspects Fuelless Motor for Airplanes”, and “Lindbergh Tries Motor That The Earth Runs.”

One story even stated that, at its request, Lindbergh and Lanphier were flying to New York to show the motor to the Guggenheim Foundation for the Promotion of Aeronautics.

Later reports, however, emphasized that Lindbergh actually had nothing whatsoever to do with the experiments, and that he had just witnessed a couple of the demonstrations as the guest of his friend, Major Lanphier.

The Selfridge tests seemed to satisfy Lanphier and his associates, how-ever, and during the period he was there, the model the technicians built obtained as high as 1,800 revolutions per minute and they announced its performance was entirely satisfactory. It was estimated these motors would run for 2,000 to 3,000 hours before the magnet center would have to be recharged.

A man named Dr. F. W. Hochstetter, of the Hochstetter Research Laboratories in Pittsburgh, hastily called a news conference and displayed models of what he said were the “Hendershot Motor.” He demonstrated them, and when they wouldn’t work, he declared Hendershot was a fake, and that the motors worked only because of power derived from concealed pencil batteries.

After he exhibited his models of the motor, Dr. Hochstetter announced that they wouldn’t generate enough electricity to, “…light a 1-volt fire-fly” or to “…stitch a fairy’s britches.”

Noting the lavish lecture room in a New York hotel which had been rented by (or for) Dr. Hochstetter for the press conference, Dr. Hochstetter was asked [by one reporter] why he was so interested in the Hendershot demonstrations and in trying to discredit them. He replied merely that he had “come to expose a fraud which would be capable of destroying faith in science for 1,000 years” and he claimed his only motive was that “pure science might shine forth untarnished.”

It was obvious to those who were pro-Hendershot that, in view of all the fuss and bother of such a noted scientist as Dr. Hochstetter, somewhere behind it all, someone was anxious for the innovation to be ridiculed.

When approached with the accusations, my Father smiled and told reporters, “Dr. Hochstetter is correct, to a degree. I have concealed batteries in a model or two because I found that I could not trust some of my visitors, and I also had evidence that someone had tampered with my work. So, I put a couple of batteries in on occasion to lead the intruders away from what I was working on.”

He added that Major Lanphier and his army technicians were proof enough of his claims. “I didn’t build the motor that was demonstrated at Detroit,” he pointed out.

“That was built by Army men under orders from Major Lanphier and under my direction. I didn’t even so much as wind the motor. They built the motor and it works. That’s my answer to all the critics—it works.”

Dr. Hochstetter and his associates also claimed my Father had signed a contract and received $25,000 for exploitation of the motor, but after a brief period of excitement, the matter was dropped—unproven.

Not long after his demonstrations of the motor, Dr. Hochstetter died under unusual circumstances. He was in a Baltimore and Ohio train wreck, and he was the only passenger on the whole train who lost his life!

My Father was the butt of many jokes and comments at the time of the debates about his invention. An artist, drawing for one of the Pittsburgh papers, depicted him in a cartoon riding a propellorless airplane. The caption made fun of him.

In later years my Father remarked, “Every time I see a jet plane go over now, I think of that cartoon and how everyone laughed at me for suggest-ing a plane could some day fly without a propeller. Twenty-five years ago I tried to tell them that.”

As suddenly as it all started, the publicity and sensationalism of the Hendershot motor stopped. The last news story to appear was on March 10, 1928, when a small article appeared in most papers saying that Lester Hendershot was a patient in Emergency Hospital in Washington.

The personal account he gave was much the same as the newspaper quote, with the minor exception that he was it by a bolt of 220 volts, not the jolting 2,000 the over-eager reporter had written. He was demonstrating the motor in the patent office, and the shock paralyzed his vocal chords, resulting in several weeks of recuperation before he completely recovered.

Something happened during this period that could explain the actions of Dr. Hochstetter and his associates. My Father said that while he was in the hospital, he was approached by a large corporation to stop his activity in connection with the motor or generator.

Until the day he died, he would not reveal the name of the company, only that if he were successful with his generator, it would be a serious threat to their multimillion dollar industry. He named the sum he accepted as $25,000, and the condition was that he was not to build another unit for twenty years. That’s when he dropped out of sight.

I’ve thought about the bizarre events connected with the generator, and feel it is possible the “large corporation” first tried to stop the activities through Dr. Hochstetter. When this failed, they approached my Father personally and bought him off. It’s interesting to note that one of the doctor’s charges was that he was paid $25,000 to exploit his work. Isn’t it odd that this is the same figure actually paid, but to stop his activities, but was quoted before he was approached with the offer?

My Father admitted that he and the family lived in constant fear, as we were being contacted every so often by crackpots who had delved into the records and discovered his creation, and had gone to the trouble of searching him out. Some of them, he suspected, were representatives of subversive groups and/or foreign powers.

This latter charge seems a little exaggerated, but was supported by a series of letters he received from a fellow in Ohio in 1952. He had traced my Father by going back to his hometown in Pennsylvania and talking to my uncle about the generator.

The first letter explained that he was a part of a group of scientists who were privately financing their own research on the same phenomena my Father discovered in 1928. He emphasized they would not allow backing by any organization or government since an invention such as the Hendershot Generator should be for, “all the peoples and should not be controlled by national governments, but should be given gratis to the World Government when it is ready to assume World Responsibility.”

He was critical of my Father for allowing the military to look at it in 1928.

That letter was written in April, and in June a postcard came with the following terse message, “Will shortly make public via radio and news-paper, connection your generator with ‘Flying Saucer Propulsion.’ Request Security Clearance from Security Chief your group within forty-eight hours. Have succeeded in duplication of your Generator.”

In July my Father received a four-page hand-written epistle from the Ohio man. To my knowledge, it was the last letter the writer sent on the subject. He discussed information his intelligence had received on flying saucers, modestly admitting his sources were better than the CIA or the FBI, which he claimed had investigated him several times. He intimated that a Pasadena scientist had recently been kidnapped because he was working on an attempt to adapt the generator to aircraft.

Then he went into a long and rambling dissertation on how he got interested in what he called the “Ether Vortex Phenomena” and the generator. He explained that the magnetic field in the earth and volcanic action are related, according to his studies. He had spent two and one-half years in Japan working with Japanese volcanic scientists on the subject.

He mentioned one study he had made, and pointed out that the shift of the strata causing the volcano was due to a rotation of the Electromagnetic Field of the volcano at high speeds. He urged my Father to write a complete paper on his findings and publish them (preferably send them to the Earthquake Research Institute in Tokyo).

Referring to a particularly bad earthquake which had just occurred in the Los Angeles vicinity a few months before, the writer warned my Father not to operate his generator in the area near the San Andreas (seismic) Fault which runs through the area.

He said, “You may not believe it, but you can cause earthquake activity to increase if you continue to operate your generator in that district. I am wondering if you were not directly responsible for the recent earthquake near Los Angeles?”

Then he promised that he and his associates would keep the possibility of his involvement in the earthquake to themselves.

Letters such as these, plus occasional phone calls when the callers would not identify themselves, and a threat from an admitted Communist which was turned over to the FBI, caused my Father concern much of the time. If a large organization would take over the generator and its re-search, all he wanted out of it was enough money to take care of himself and his family in the future years.

One of the most encouraging offers came in September of 1956 when my Father received word that officials of the Mexican government wanted to meet with him and discuss the possibility of using his generator for the rural development program in Mexico.

Government officials flew to Los Angeles and drove out to our house, where our family doctor who spoke Spanish acted as interpreter. Arrangements were made for the family to go to Mexico City, and for my Father to work with Mexican technicians on the generator.

We all flew to Mexico City and were housed in an apartment near the home of the Director of Electricity. My Father supervised the Mexicans in building a model. He had been working with them for several weeks becoming more and more tense as time passed. He confessed to my Mother that he was frightened because he understood no Spanish, and his fellow workers talked constantly in little groups by themselves, often glancing over at him. He couldn’t understand a word they were saying, and it worried him considerably.

One morning in February of 1957, the laboratory called and asked where my Father was. My Mother told them he had left for work in the morning, and if he wasn’t there, she had no idea where he might be. She became increasingly concerned as the day passed and there was no word from him.

That night he didn’t come home, and we were on the verge of hysteria by next morning, then we received a telegram from Los Angeles. My Father’s fear had worked itself into a nervous frenzy and he had rushed to the airport the day before and taken a plane for California. To the day of his death, it was a closed subject and he would never explain why he was compelled to leave us so suddenly under such strange circumstances, except that he feared for his life.

The final attempt to promote the generator came in the latter part of 1960 when a Dr. Lloyd E. Cannon convinced my Father that he had the facilities to present the project to the United States Navy for research and development.

Cannon said he was the General Manager of his own company, Force Research of Los Angeles, Palm Springs and the Mojave Desert. Cannon explained that his group was made up of many dedicated scientists of various fields who contributed time and knowledge to Force Research projects. The range of experimentation covered electronics, astronautics, free energies, propulsion, and parapsychology.

Under my Father’s supervision, two models were built and 100 copies of a fifty-six-page “proposal” were printed for presentation to the various government agencies and politicians who would have to review the project for its consideration.

After the completion of the proposal and it had been sent to the government with no results, Cannon traveled the southwestern United States with the models trying to raise money for research. His visits were increasingly less frequent to our home until 1961, when a tragic climax to this story occurred.

On April 19, 1961, upon returning home from school, I found my Father dead. It was recorded as a suicide without any further investigation. For those who might be interested in my Father’s analysis of how his generator worked, the following are his theories on the subject:

This field of magnetism surrounding the earth is similar to the field of magnetism in a man-made generator.

The rotor of a generator is revolved by some means of power, cutting the lines of magnetism, creating electric power. The earth is turning inside of a field of magnetism. That, no one contradicts, yet it is claimed there is no power to be derived from it.

Let’s say we have a mechanism that will collect, polarize and create a positive and negative connection to this tremendous power that is ever-present on the earth.

Take a survey compass. You can hold the needle east or west, and let go of it, and it immediately goes north and south. This same power, when cut by the proper apparatus as the earth rotates inside this magnetism, will produce power, the amount of which is not calculated at this time.

As long as the earth rotates around the sun, it will create electric power which some scientists claim does not exist. Yet, we dig into the moun-tains for material that costs us unbelievable sums, to create the same power.

This magnetism surrounding the earth is in the same relation to electric power as uranium is to atomic power. Earth’s magnetism is ever-pres-ent at any height or depth. It is equal to uranium as a by-product for power, namely electricity.

Magnetism must be cut. The lines of force circling the earth are constant and if this force is broken up, and polarized, you have the equivalent of uranium broken up, which creates a heat and in turn creates power.

Breaking up the forces of magnetism, polarizing them, thereby creating a resistance for power, is the same principal as atomic energy.

Scientists claim it requires friction to generate electricity. I claim the earth rotating as it does, according to scientific theory, creates friction as a generator. The ever-present magnetism is the field, or stator.

We have only to utilize this source of power to light every home, high-way, bridge, airplane or any type of thing that cannot now be lighted because of inadequacy of present facilities.

A very small unit composed of wire, a magnet, several especially designed coils, condensers, collector units, and a few other minor items, will cut this force. Another especially designed mechanism will polarize it, giving a positive and a negative connection to any resistance and the result is the generation of electricity.

There you have the theory of how to create electricity from the magnetic force of the earth, as written by a man with only a high school education.

As years went by I’ve always wanted to continue with my Father’s invention, but have worried myself about possibly running into the same problems my Father did.

It would not do my Father justice just to stop all work on it and now I am ready to fulfill his dream. Since childhood I have been fascinated by electricity and have spent over twenty-six years in the electrical trade.

Of his three sons, I alone have pursued this fascination and have applied my knowledge and experience to carry on my Father’s work.

Principles of the Hendershot Motor

The Earth Inductance Compass & the Hendershot Motor


Referenced in the article: “THE SO-CALLED HENDERSHOT MOTOR by Gaston Burridge” is an article by the company Utily Engines. This is very good data and some data can be verified in other areas.

NOTE: “In the May, 1953, issue of “Fate” magazine appeared an advertisement from the “Utility Engines’ professing to have plans for sale of a so-called Hendershot motor for $2.50. Suddenly, all mail was rejected by the address of the “Utility Engines”! I asked Hendershot about this matter. He told me he learned of it soon after the advertisement was published. Soon after that he learned about the plans they were selling and using his name. They were doing this, Hendershot claimed, without his permission or consent. He told me that he promptly informed the postal authorities of this circumstance. “They must have done something about it, for I heard nothing more about them,” he said. Hendershot was quite emphatic to me regarding the plans put out by the “Utility Engines” not being of his device. He was so emphatic, in fact, I felt he, like the maiden, “didst protest too much”. Thus, ‘the Ol hound dog’s nose’ went to the ground! In due course it came up with the information furnished by an acquaintance of Hendershot’s to the effect that Hendershot had remarked at the time, while the “Utility Engines” information was not his device, “it was pretty damn close!””


“The first model consisted of a ring magnet less than three inches in diameter. Around the magnet were coils rigged as only Hendershot knows how to rig them, and another set of coils pass through the center of the ring.”

The second model is built around a ring magnet, the outside diameter of which is seven inches and the inside diameter six inches.”
