Best ElectroStatic Influence Machine? Answered
What's the best electro-static influence machine? Like which one can output the best sparks for the spinning input, ie which one is the most efficient?
Sectorless Wimshurst (Bonnetti)
Van De Graff
Or some friction (not influence) based electrostatic machine?
All of the influence machines are pretty similar, but I need to make a fairly small one (think disk diameters of only 3 or 4 inches), and i'm trying to make it hand held, so efficiency is a must!
