Electrum is a giant sculpture created by artist Eric Orr and the electric engineer Greg Leyh, built around the largest Tesla coil in the world. The coil is 37 feet high and produces three million volts of electricity.
As tall as a four-story building, the coil produces an arc that shoots 15 meters into space, runs power of up to 130,000 watts and produces three million volts on the terminal when operating. On top of the sculpture is the spherical Faraday cage that can safely hold one person. The sculpture is installed on a private Gibbs Farm in New Zealand, as a part of the art collection of Alan Gibbs.
