Tesla coils are the brain child of the early 20th century scientist Nikola Tesla—a man with roughly 300 patents to his name ranging from arc lamps to a helicopter prototype. Although not all of Tesla's ambitious plans came to fruition, his legacy lives on as electricity enthusiasts are still hard at work building enormous Tesla coils. One group is actively seeking funding to build the world's largest pair of Tesla coils capable of producing arcs around 100 yards long. The proposed 10-story Tesla Coils would be the largest ever built. Image Courtesy Lightning on Demand.
