I was marveling over the fact that the largest theoretical size for the coil is something that you might conceive of building seriously. I sure would like to see it happen, at least in my lifetime. I'm ready to drop everything in my life and just haul off and build this thing. It's one of the few places where the power companies actually said that they wouldn't mind something like this being attached to their grid. They have plenty to spare, so they wouldn't even notice it.
Lightning causes other damage and mayhem as well, other than just hitting people.
It hits transmission lines, knocks out big power plants, all sorts of problems. As far as lightning research, I think it has a lot of merit. There's mysterious things about lighting that still haven't been found out. The peak in lightning research was around 1960, and after that it just petered off. They left a lot of unanswered questions.
