Ah, another good item to watch for at yard sales. I used to repair
power wheel chairs and other medical devices and have mixed feelings
about diverting their still-useful repair components to other
purposes. For various reasons not all users quality for government
help.

Not to worry. Bicycle power generation is a nanoscopic market.

In my yout, I actually tried to maintain ~70 W into a
bicycle crank over an extended period of time. Best I ever
did consistently was about 30 minutes. Then I was All Done.

I could not have done that unless I was in the breeze
of my trusty *90 W* fan.  :)

I really need only 30W to maintain a battery powering this laptop or
my 22" HDTV. A USB flex light is enough to illuminate the keybard to
type when the room lights are off. 50W would be the goal, though I
might design the frame and drive for 500W, which I can't maintain very
long if at all.

This would be my model, a foot-powered lathe meant for continuous
duty, unlike a sewing machine where you stop at the end of each seam.

I don't think I could pedal a crank and type at the same time, but the
treadle drive is well proven for delicate work.

I think you mentioned using a stepper motor
as a generator in a wind charger application.

That, combined with your PV panels sounds like a
valuable parallel wattage source for your
treadle genny.

Actually I have reject Segway parts for mine. They encouraged us to
play, occasionally on company time.

They can't (and definitely shouldn't) go into customers' machines, so
don't ask.
