A typically innovative and unique new project from Albert. I asked the 'Bing' search engine about this and the bald statement came back: "A raindrop acquires a negative charge of 3.0 x 10-18 C as it falls". That's a pretty small charge. Interesting to know how this varies, and bears on raindrop capacitance to produce what voltage... And what about during thunderstorms?

P.S. Going wildly off-topic for a moment... consider the Earth as a raindrop. What charge does it possess overall? Relative to what? Does this question indeed mean anything at all? Though I can imagine the Earth might hold a surplus or deficiency of electrons...
