Researchers Create Extra-Long Electrical Arcs Using Less Energy, University of Canterbury Study

Published: Nov 09, 2011

Researchers at the University of Canterbury, in New Zealand, have developed a new, lower-voltage method of generating extra-long, lightning-like electrical arcs. The arcs are created when an electrical impulse is applied to a thin copper wire that subsequently explodes. By jump-starting the arcs using exploding wires, as opposed to the traditional method of directly breaking down air, the researchers reduced the amount of voltage needed to create an arc of a given length by more than 95 percent.
