The Nikola Tesla electric car anecdote refers to a supposed invention described by Peter Savo, who claimed to be a nephew of Nikola Tesla.

Description

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 and was connected to a 6-foot-long antenna. The car was claimed to have been driven for about 50 miles at speeds of up to 90 mph over an eight-day period.^[1]^[2]

The story has been subject to debate due to the lack of physical evidence to confirm both the existence of the car and the fact that Tesla did not have a nephew named Peter Savo. Tesla's grand-nephew, William Terbo, has also dismissed the Tesla electric car story as a fabrication.^{[citation needed]}

A number of web pages exist that perpetuate this anecdote.^[3]^[4] The continuous recycling of reactive power is a method by which the car could have been powered,^[5]^[6] though there is a lack of verifiable evidence contemporaneous to the story. If the car was powered (for the most part) by the reuse of reactive power, a thorough review of these anecdotes would be required to determine if an extremely high quality factor is responsible for significantly offsetting power losses.^[7]

With the exception of these points, every other account of this purported demonstration automobile is based solely on the Peter Savo story with additional embellishments added by subsequent retellings.^[8]^[9]^[10]^[11]^[12]^[13]
