Can I generate power from with a generator installed on my water pipes?
Every time I flush the toilet, have a shower, wash the dishes, I think to myself... what a waste of water flow energy. I'm no electronics expert, but I figure connecting a 12 volt dc pump (like a boat bilge pump or something off the hardware store shelf) backwards inline (when I say inline... I mean no leaks... and just operates whenever I use water day to day) with the water supply to my house could generate a little top up trickle to some batteries along with a little solar & wind electricity generation project. Then I think, hang on, as soon as I hook the pump up to a battery... it will just try to pump water back out of my hot water tank house back down the pipe... so looking for ideas here? Anyone out there had a play with this concept?
