This is an account of the author's investigation, on behalf of the Canadian government, into the life and ideas of the eccentric genius Nikola Tesla. This is a completely revised and redesigned edition, with a new introduction by the former head of the Tesla Museum, a new chapter and a selection of photographs of Tesla and his work in search of the holy grail of electricity - the transmission of power without loss. As a student in Prague in the 1870s, Tesla saw the electric induction motor and patented his discovery, -the first of many inventions whose plans seem to have come to him fully fledged. He worked for the Edison company in Paris before emigrating to the US and battling with Thomas Edison himself to ensure that alternating, rather than direct current, became the standard. He sold his patent in the induction motor for $1 million dollars to George Westinghouse, who used this system for the Niagara Falls Power Project. Moving to Colorado Springs, Tesla worked on resonance, building enormous oscillating towers in experiments which still intrigue today. In later life Tesla became a recluse, bombarding newspapers with eccentric claims, including energy transmissions to other planets. Though he died alone and virtually forgotten, rumours gradually grew that Tesla had made further remarkable discoveries. In an attempt to replicate his experiments, people still build Tesla towers and puzzle over the possible link with low-frequency broadcasts which can supposedly disrupt the weather and affect the human mind.
