So Tesla moved into Colorado Springs, where one of his generators and electrical systems had been installed,and set up his lab. Why Colorado Springs? Well, his lab in New Yorkhad burned down, and he was depressed about that. And as fate would have it, a friend in Colorado Springs who directed the power company, Leonard Curtis, offered him free electricity. Who could resist that? After setting up his lab, he tuned his gigantic Tesla coil through that year, trying to get it to resonate perfectly with the earth below. And the townspeople noticed those weird effects; Tesla was electrifying the ground beneath their feet on the return bounce of the wave. Eventually, he got it tuned, keeping things at low power. But in the spirit of a true hacker, just once he decided to run it wide open, just to see what would happen. Just what was the upper limit of the wave he would build up, bouncing back and forth in the planet below? He had his Coil hooked to the ground below it, the 200 foot antenna above it, and getting as much electricity as he wanted right off the city power supply mains. Tesla went outside to watch (wearing three inch rubber soles for insulation) and had his assistant, Kolman Czito, turn the Coil on. There was a buzz from rows of oil capacitors, and a roar from the spark gap as wrist-thick arcs jumped across it. Inside the lab the noise was deafening. But Tesla was outside, watching the antenna. Any surge that returned to the area would run up the antenna and jump off as lightning. Off the top of the antenna shot a six foot lightning bolt. The bolt kept going in a steady arc, though, unlike a single lightning flash. And here Tesla watched carefully, for he wanted to see if the power would build up, if his wave theory would work. Soon the lightning was twenty feet long, then fifty. The surges were growing more powerful. Eighty feet -- now thunder was following each lightning bolt. A hundred feet, a hundred twenty feet; the lightning shot upwards off the antenna. Thunder was heard booming around Tesla now (it was heard 22 miles away, in the town of Cripple Creek). The meadow Tesla was standing in was lit up with an electrical discharge very much like St. Elmo's Fire, casting a blue glow. His theory had worked! There didn't seem to be an upper limit to the surges; he was creating the most powerful electrical surges ever created by man. That moment he set the record, which he still holds, for manmade lightning. Then everything halted. The lightning discharges stopped, the thunder quit. He ran in, found the power company had turned off his power feed. He called them, shouted at them -- they were interrupting his experiment! The foreman replied that Tesla had just overloaded the generator and set it on fire, his lads were busy putting out the fire in the windings, and it would be a cold day in hell before Tesla got any more free power from the Colorado Springs power company!
