William;

Just read your note below. Picked up a spindle motor, hooked up the
scope and gave it a spin. Gots 8Vpp just from spinning by hand. I
may have to hook this up to my steam engine and run a pic that way!

Or maybe that is the answer to the thread? Have the individual get
a small model steam engine, perhaps a Cheddar like mine(burns butane,
contains water injector pump) hooked up to one of your little disk
drive spindle motors to run the pic and a couple other small loads?
No?
