Tesla's electric car on the ether

The 1960s, aeronautical engineer named Derek Ahlers met Peter Sava and developed a long friendship with him. During their ten-year acquaintance, Savo Ahleru is often talked about his famous "uncle" by Nikola Tesla and his achievements in the 1930s. (Savo was the younger cousin of Nikola Tesla, and although he was not the real nephew usually called him "uncle").
1930th Nikola Tesla was asked his "nephew" Savu Petra to come to New York. Savo (born 1899, and thus 43 years younger than the Tesla) is served in the Austrian army and was a trained pilot, and gladly took the opportunity to leave Yugoslavia. He immigrated to America and settled in New York. In a series of interviews in 1967, Savo told about his interest in the story of Tesla's electric car.
During the summer of 1931, Tesla is called Sava River in Buffalo, New York, to publish and test a new type of car that Tesla has developed its own funds. Westinghouse Electric Company's and the Pierce Arrow Motor Car have developed the experimental electric car under the leadership of Tesla. Pierce-Arrow company was then owned and operated financial cap Studebaker Corporation, and used this stronger financial base for the introduction of many innovations. Between the 1928th and 1933, the company has come out with a new eight-cylinder models in the series and V-12 engine, the futuristic cars parlor Silver Arrow, the new styling and technical improvements. Consumers have responded to it, and selling cars Pierce-Arrow was further increased the company's share of all the narrower market of luxury cars 1930th With such a rush of confidence, "unrealistic" Projects like the Tesla electric cars were within a conceptual sphere. With the company's traditional blend of arrogance and naivete, everything seemed possible.
Thus, the test elected Pierce-Arrow Eight of 1931. with factory test polygon in Buffalo. Removed his internal combustion engine, a clutch, gearbox and transmission to the rear wheels were left intact. He stayed, and 12-volt battery, but it is connected to the transmission of electric motor of 80 horsepower snaga.Električni automobiles have traditionally had the engine on the DC, since it is the only current that the battery can be released. Could it be used for DC / AC converter, but the equipment at that time was too large to fit in the car.
Twilight of electric cars has been long overdue, but the Pierce-Arrow was not equipped with a simple DC motor. It was an electric AC motor designed for 1800 rpm. The engine was 102 cm long and had a diameter of 76 cm, was brushless air-cooled with the front fan and had a double cable, which was conducted under the dashboard, but it was not connected. Tesla would not reveal who manufactured an electric motor, but it is believed that it could be some of the departments of Westinghouse. At the rear of the car is built in 1.83-m long antenna.
Mr. Savo has fulfilled the request of his older cousin joined him. In New York they boarded the train to the northern part of New York. During the trip, the inventor did not want to talk in detail about the nature of the experiment. Upon arriving in Buffalo, went into a small car repair shop where they found a new Pierce-Arrow. Tesla opened the hood and adjust some things on an electric AC motor under it. Then they started to prepare Tesla equipment. In a nearby hotel room electrical genius has created a device. He brought 12 special vacuum tubes in a suitcase-like box. Savo said the tubes were "unusual shape", though they have been at least three identified as a rectifier tube 70L7-GT. They were connected to the device that was located in a housing measuring 61 x 30.5 x 15 cm. It was not anything more than short-wave radio station. It was in an electronic circuit with 12 vacuum tubes, wires and various resistors. Two rods of diameter 6 mm and length 7.6 cm clearly served as connectors for the motor cables.
When they came back to test the car, put the box on the already prepared a place under the dashboard on the passenger seat. Tesla has pushed the two contact rods and looked at the voltmeter. "Now we have power," was published, giving the keys to the ignition to his nephew. On the dashboard dials were additionally showed that the values ​​that Tesla is not explained.
At the request of his uncle, Savo included motor. "The engine is now on the move," confirmed the Tesla. Savo did not hear any sound. Despite this, put it in gear, pressed the accelerator and took the car from the garage. Mr. Savo that day long driving this car without fuel, 80 kilometers at Buffalo and the nature around him. The speedometer calibrated to 192 km / h, Pierce-Arrow has achieved a top speed of 145 km / h, with the same quietness of the engine. While driving environment of the city, Tesla has become more relaxed and confident in the success of his invention. He began to open his nephew about his secrets. The device was able to supply vehicle power forever, but, moreover, was also able to satisfy the energy needs of a house - and with more than enough energy.
Although, according to Savini said, initially refrained from explaining the principle, Tesla was finally told that his only condition set for the "mysterious radiation which comes from the airwaves," and that "available in unlimited quantities." He added that "mankind should be very thankful for his existence." Over the next eight days, and Savo Tesla tested the Pierce-Arrow in the city and its surroundings, the snail speed to 145 km / h. Performance were the same as any of the then powerful car with more cylinders, including a 6-liter Pierceovu "Eight" of 125 horsepower.
Tesla said River to the receiver of energy will soon be used to run trains, ships, planes and cars. The inventor and his assistant finally drove the car a secret, predetermined location - at the end of an old barn farm house 32 kilometers from Buffalo. There they left the car, Tesla took the ignition key and a receiving device with you.
Enigmatic aspect of the story did not end there. Mr. Savo heard a rumor that the secretary spoke openly about the secret testing and was discharged because of indiscretions. This may explain the distorted stories about the tests that have appeared in some newspapers. Tesla was asked where it comes from energy, when it is obvious that the car has no battery. "The airwaves are everywhere around us," he replied hesitantly. Some people suggested that Tesla was mad and that is somehow associated with evil, occult powers. Such treatment in the media he was angry, so he finally picked up his mysterious box and returned to his laboratory in New York. Thus ended the short-term relationship with Tesla's inventions using the launch vehicle. "
Thus, the great genius had a solution but again the interests of capitalists and "market-able", gutted his invention
at the root, as many times before.
