Hello Sam,

I just happen to have a variety of motors right now for a short time but I will get more free motors in the future. I havnt tried to generate electricity with them besides hooking up my meter and giving them a spin out of curiosity. Ill try to snag an alternator out of a stairmaster next chance I get. Would that be more efficient than a brushed motor? 

Treadmill motors in north america are 90-120V, 15-25A. Can't remember the rpm ratings. Don't know how that would translate when used as a generator.

I've seen treadmill motors be used for wind turbine generators. It was
featured in Make Magazine volume 5, link to the project page here:

It calls for a "Treadmill motor<http://makeprojects.com/Item/Treadmill_motor>
, 260 volts DC, 5 amps, with a 6" threaded flywheel" and certainly seems
like the hardest part to source for the project.

I would certainly be interested in one of these motors, however I'm in
Kingston, so it would probably be a little while before I could take it off
your hands.

Does the ModLab have a scrap bin? When I visited Kwartzlab they had a shelf
with tote bins filled with goodies, such as the linear actuators you
mentioned, among other things.
