Pumping Water from a Well
If you want to earn your stripes as a true off-the-grid biofuel user, then pumping your own water is an activity sure to get you there for several reasons.
First of all, you're not connected to a city water utility. Second, your generator has produced enough juice to save you the task of carrying water from the well. And third, you've built a pump that's not going to drain the generator.
Steve Spence did this at his homestead in upstate New York. After working with several different pumps, he reported in his blog at Green-Trust.org that he was pleased to have found a piston pump that could be cranked, pedaled or connected to the power system run off his biofueled generator.
