Calling all Tesla fans! Electrical engineer Greg Leyh and his team at the Lightning on Demand organization (LOD) in California are raising the funds necessary to build the world's largest twin Tesla coils (ten stories high, about 120 ft/37 m) that will be capable of generating electric arcs more than 200 feet (60 m) long. Dubbed the "Lightning Foundry," the project currently consists of a working 1:12 scale prototype. When complete, a towering pair of coils will fill a football field-sized area with massive electric bolts that researchers hope will reveal some of the mysteries of this beautiful but deadly force.
