This $5 lamp is powered by gravity (and just destroyed its funding target on Indiegogo) | VentureBeat | Gadgets | by John Koetsier I can't open that file. Is it simalar to this? Or is it using water flow to turn a generator?
Not the same thing at all. If you want, I'll try to PM the file to you, opened readily here. It's hydro.
Always learning. Sure, please do. I remember the medical hospitals in Korea using a gravity driven fluids pump ( was on M.A.S.H 4077) when the power failed.
