In 1812, Charles Redheffer, in Philadelphia, claimed to have developed a "generator" that could power other machines. The machine was open for viewing in Philadelphia, where Redheffer raised large amount of money from the admission fee.[13] Redheffer moved his machine to New York, after his cover was blown in Philadelphia, while applying for government funding.[14] It was there that Robert Fulton exposed Redheffer's schemes during an exposition of the device in New York City (1813).
