Brad, I suggest a much better use: turn it into a windmill. I finally got my hands on a motor from a 9-track I scrapped. It puts out several amps at 24V+ when I hand-spin it. It will do nicely as a current source to charge a lead-acid battery, especially where I live: http://en.wikipedia.org/wiki/Altamont_Pass_Wind_Farm As Tony already mentioned, it won't have enough power output to be good for a go-kart. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]
