"As the respected Smithsonian magazine has noted: “He claimed that he had developed a motor that ran on cosmic rays; that he was working on a new non-Einsteinian physics that would supply a new form of energy; that he had discovered a new technique for photographing thoughts; and that he had developed a new ray, alternately labelled the death ray and the peace ray, with vastly greater military potential than Nobel’s munitions.”
The claims he invented an electric car are usually related to a story about a ‘black box’ powering the motor with free cosmic energy."

"Electromagnetic (EM) waves which Tesla declared is a free source of power that is “everywhere present in unlimited quantities”."

"The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays."

"The universe is full of radio emissions. Many objects in space emit radio waves, and scientists can detect them here on Earth after they have filtered through the atmosphere. These waves are similar to the kind your car antenna picks up, the kind that bring you “This Week’s Greatest Hits” or yesterday’s political commentary.
Scientists first detected radio waves coming from an astronomical object — the Milky Way — in 1932."

"Tesla was able to amplify and convert the invisible electromagnetic radiation called radio waves into electricity to power the AC motor in the 1931 Pierce-Arrow"
