Post #4 discusses that watts out is less than mechanical watts in.. At 100% efficiency the alternator in the original post will take over two HP at full output. More than most drill motors can supply.Maybe I missed it mentioned, but it will most likely take more than a drill to spin the alternator especially once the battery gets enough of charge that it starts to charge faster. I can' t tecal the numbers off hand and at work at the moment. I think you will need at least four horsepower to make it work.
