Otherpower Low RPM alternator

Just a short demonstration of the same low rpm alternator we would normally use for a 10' diameter wind turbine. This one is built on a stand with a hand crank so folks can get an idea about the work involved behind producing a bit of power to perhaps light up a bulb or...

This sort of alternator might be useful for other power generating experiments... mostly it's for fun and education. I expect they'd work great for your overunity motor generator experiments and low rpm vertical axis wind turbines! (just kidding). This particular alternator (And there are other configurations possible) will produce 12 Volts at about 65 rpm, 24 volts at 130 if it's unloaded. If it were setup to charge a 24 volt battery, we'd get about 700 Watts at 400 rpm. The limit for this particular machine is about 30 amps at which point it would be down to about 60% efficiency. At lower current levels it is more efficient. Lots of fun anyhow!

What rpm is needed for maximum efficiency? And what is the avg amp output? Also if I'm interested in purchasing where would I go.

Thanks Lucas
