I have a bunch of worn out Weed Eaters and the 2 cycle engines still run. I can't bring myself to throw them away because one day I might need them for something. Hmmmm..... I've got an automobile 12 volt generator out in the shed. Now, if can hook up a pulley to the Weed Eater engine, I can spin that generator and get up to 60 Amps at 13.8 VDC. Hmmmm... I better filter that raw DC through a Car or Lawnmower Battery to reduce or eliminate Hum, Hash, Ripple, Noise, etc. I'm pretty sure I can use that to recharge batteries or power 12 volt items. The cool thing is that the Car Generator has voltage regulation built in. Anybody else got any other ideas like maybe using water power to spin a generator?
