Nikola Tesla’s Radio Phone

The junk-heap super phone

Tesla advocates in the above letter using a multiphase induction motor to increase the efficiency of an electric car. It is likely that his electric car that he built in the 1930’s utilized one of his multi-phased induction motors. The power source, according to his assistant Authur Matthews first hand account, invented by Tesla, was a unique primary battery that was used to power the car.

This battery was unique in that it had replaceable zinc electrodes. When the zinc was used up it was simply replaced. This system would require a direct current to multiphase power converter. Tesla states that he made numerous statements in publications in regards to using electricity to power a car. Tracking down these statements should dispel the myth that his car was powered by radiant energy.
