YOu will only get about 30 watts out of that pipe. Use a larger pipe if possible. Speed should be OK at about 1200 rpm (4 inch pelton). Try trimming the field current to optimise speed. CAr alternator efficiency will be low. You could get a little more power by building a permanent magnet alternator. I can specify something if you are interested. -- Hugh Scoraig Wind Electric http://www.scoraigwind.co.uk/ ------------------------ Yahoo! Groups Sponsor --------------------~--> Yahoo!
