Good thinking Erik. I suppose the next Q is how far down is it to the water table? And thats a job for a wind mill tower... But you knew that. What would be neat is a big remote switch rod running up the tower to a clutch to disconnect the wheel from the pump jack when the tank is full, and connect it to an alternator for battery charging. A dog clutch could handle that as the normal water pump fan doesn't turn that fast. About a 10x gear up to an alternator ought to give some usable wattage for the batteries. I spent a couple years of my early life on grandpa's farm in Madison County Iowa, several miles "off grid" as that was long before the R.E.A. It was just how it was in those days, a farmer was self sufficient or starved. We ate well, very well in fact. Big glass single cell lead acid cells, about 5 gallon size, 10 of them gave us a bit if light in the evenings, lights in the barn to milk the cows by and ran the maytag washer after the put-miss-put backfired and broke grandmas ankle, first electric washing machine in rural Madison County by quite a few years. Yeah, that Madison County, made famous 80 years later by Eastwood and Streep in Bridges. I was over quite a few of those bridges in a team of horses drawn wagon back then. A simpler, but not always easier time back then. > > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
