>> water in, "Lightning" out. I never managed to get a kelvin generator to work, usually blaming it on 'l= osses exceed generation." But apparently there are subtleties to flow rate= that I was previously unaware of as well. https://www.youtube.com/watch?v=3DCr1w2nTfWYY Does anyone know of a somewhat more quantitative treatment of electrostatic= devices from this era? As a teenager, I read Moore (http://www.amazon.com= /Electrostatics-Exploring-Controlling-Electricity-Includes/dp/1885540043 ) = a lot of times, and built some of the projects. And then I took college ph= ysics, and became a SW engineer. And then, years later, I noticed that I'v= e never seen anything remotely numeric attached to any electrostatics proje= cts; not even qualitative numbers like "if you shorten this distance here, = you increase/decrease the voltage produced"=85 Also: http://www.cavemanchemistry.com/dirod.html BillW --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
