Nikola Tesla's long held dream was to create a source of inexhaustible, clean energy that was free for everyone. He strongly opposed centralised coal fired power stations that spewed carbon dioxide into the air that humans breathed. When Tesla died in 1943, he was bankrupt, alone and teetering on the verge of insanity. But the way this man changed the world is like no one else. Tesla discovered and patented the rotating magnetic field, the basis of most alternating-current machinery. During his lifetime he obtained around 300 patents worldwide for his inventions. So in simple words, anything from radio to TV to WiFi would have not been possible without the genius of Nikola Tesla.」7月1日 23時22分
