This would be a good way to show electricity generation at a museum or something though (although a light bulb has always been the popular choice for hand powered teaching).

I agree that it's not very practical, but the addition of a capacitor should help there, given that an ordinary clock can run for MONTHS on a single "AA" type battery, a relatively small capacitor should give you hours if not days. More like the good old fashioned mechanical clocks that needed winding every week.
Good work.
