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.
