Tesla was incorporated (as Tesla Motors) on July 1, 2003, by Martin Eberhard and Marc Tarpenning in San Carlos, California. [2] [3] [4] The founders were influenced to start the company after General Motors recalled all its EV1 electric cars in 2003 and then destroyed them, [5] and seeing the higher fuel efficiency of battery-electric cars as an opportunity to break the usual correlation ...
William Herbert Rollins (June 19, 1852 - 1929) was an American scientist, inventor, and dentist. He was a pioneer in radiation protection.Many of his inventions and investigations in medical radiography and photography have been ranked in importance with those of Thomas A. Edison, Elihu Thomson, and William J. Morton.
In the same year as the discovery of X-rays, Mihajlo Idvorski Pupin (1858-1935) invented the method of placing a sheet of paper coated with fluorescent substances on the photographic plate, drastically reducing the exposure time and thus the radiation exposure. 95% of the film was blackened by the intensifying film and only the remaining 5% was ...
Tesla, Inc. (/ ˈ t ɛ s l ə / ⓘ TESS-lə or / ˈ t ɛ z l ə / TEZ-lə [a]) is an American multinational automotive and clean energy company. Headquartered in Austin, Texas, it designs, manufactures and sells battery electric vehicles (BEVs), stationary battery energy storage devices from home to grid-scale, solar panels and solar shingles, and related products and services.
Natural color X-ray photogram of a wine scene. Note the edges of hollow cylinders as compared to the solid candle. William Coolidge explains medical imaging and X-rays.. An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.
The Tesla Roadster is a battery electric sportscar with 244 miles (393 km) (EPA) range. On November 30, 2007, Tesla released a press release titled "Martin Eberhard, Co-founder of Tesla Motors, to Transition to Advisory Board." [15] Fortune magazine reported in December 2007 that chairman Elon Musk had asked Eberhard to leave.
According to the story, in 1931, Tesla modified a Pierce-Arrow car in Buffalo, New York by removing the gasoline engine and replacing it with a brushless AC electric motor. The motor was purportedly powered by a "cosmic energy power receiver" contained in a box measuring 25 inches by 10 inches by 6 inches, which contained 12 radio vacuum tubes ...
