I'm trying to build a chamber than can recreate the process of a lightning strike. I realize that I need to charge the top and bottom (or both sides) of the chamber with extreme opposite charges, and I also realize that I need to simulate the atmospheric conditions of a lightning cloud within the chamber. I have a few questions. Number 1, does the distance between the top and bottom (or sides of the chamber) of the chamber make any difference to the possibility of generating a lightning strike? Number 2, what could I use to generate an extreme + charge and an extreme - charge? Number 3, How can I contain the extreme - and extreme + electromagnetic charges specifically to the top and bottom of the chamber, without the electric charges spreading to the synthesized atmosphere and walls of the chamber.
