Tesla coil
The current world's largest Tesla coil is a 130,000-watt unit built by Greg Leyh and Eric Orr, part of a sculpture titled "Electrum" owned by Alan Gibbs and currently resides in a private sculpture park at Kakanui Point near Auckland, New Zealand. A very large Tesla coil, designed and built by Syd Klinge, is shown every year at the Coachella Valley Music and Arts Festival, in Coachella, Indio, California, USA. Austin Richards, a physicist in California, created a metal 'Faraday suit' in 1997 that protects him from Tesla coil discharges. In 1998, he named the character in the suit Doctor MegaVolt and has performed all over the world and at Burning Man nine different years.
