wig and began scratching a picture on the sand; it was a diagram he would show investors six years later for the harnessing of Niagara Falls. Others had already developed alternating current motors, but they were terribly inefficient. Tesla did not just make some small advancement; he gave birth to an entire concept. By having two alternating currents out of phase with each other, a rotating magnetic field was produced. By creating a magnetic whirlwind the need for both commutator which reversed the direction of the current, and the brushes which provided passage for the current were no more. With the new alternating current, voltage could be stepped up or down according to the need. Now it was possible to transport electricity hundreds of miles due to the ability to carry high voltages. Instead of a installing a direct current power plant every few miles, an alternating current power plant could step up the voltage for long distance travel and then down step it for domestic use. Tesla built the ark of electricity, but getting it to float in the modern world would prove a real challenge. In an effort to help pay for college, Telsa began working for a telegraph office. He made numerous improvements to his station and was offered a job with Edisons telephone subsidiary in Paris. Tesla had followed as best he could with the developments of electricity in the New World. He took the opportunity to get his foot in the door hoping he could sell the officers of the company on his new invention. Unfortunately, the officers said that Edison was not interested. Tesla continued working for the Edison Company troubleshooting. At the same time some Germans were extremely upset about the malfunction of their railroad stations lighting plant of which the Edison Company was responsible for. The company responded by sending Tesla, promising a big bonus if he could fix the stations dynamos and make reparations with the Germ...
