Greg Leyh is an electrical engineer who has spent most of his career working around particle accelerators and high-voltage machinery. Recently Leyh has been working on The Lightning Foundry, a project to see if humans can replicate the voltage economy effect of lightning. With the help of a Kickstarter campaign and a pair of 10-story Tesla Coil towers he hopes to generate man-made lightning. Greg has agreed to take some time away from his lightning machines and answer your questions. Ask as many as you like but please confine your questions to one per post.

Effugas writes "The technology isn't new--Tesla coils have been around for a century. However, I doubt very many of us have seen much like the pictures located at Lightning On Demand--consider that, for most of these displays of extreme electrical discharge, there's a guy sitting *inside* the main electrode. I'm trying to imagine sitting in a metal ball while thirty foot electrical streamers erupt around me. Got Drool? "
