Nikola Tesla was an inventor and a mechanical and electrical engineer. He was one of the most important contributors to the birth of commercial electricity. After his demonstration of wireless communication through radio in 1894 and after being the victor in the "War of Currents", he was widely respected as one of the greatest electrical engineers who worked in America. Nikola Tesla's true dream was to supply the entire world with free energy by harnessing energy from the earth but greedy business men and companies wanted to keep this a secret so they could charge the masses for energy and make profits. Tesla than decided to try to end all wars by inventing a death ray that he would give to each country so missiles could be shot out of the sky but he would soon die living his patents behind ushering am era of devices that can weather and even a person mind.
