Electrum or Electrum (for Len Lye) (Len Lye being a New Zealand artist), is a 1998 sculpture by Eric Orr and Greg Leyh built around the world's largest Tesla coil.

[1] The coil stands 11.5 meters (37 feet) in height, operates at power levels up to 130,000 watts, and produces 3 million volts on its spherical top terminal.

[2] The sculpture is currently installed in a private area at Gibbs Farm in Kaukapakapa in New Zealand, a sculpture park art collection of businessman Alan Gibbs.

[3][4][5][6] The top, spherical electrode of the sculpture is large enough to hold a human.

[7] The piece was the subject of a 2000 documentary, "Electrum: Science as Art" and the 2011 documentary Lightning Dreams, by Alberta Chu.
