from http:pedalpowergenerator There's big differences between powering up an incandescent bulb and a CFL or LED Bulb. You will definitely feel it when you hop on a bike generator and do the comparison! This same type of idea can be applied to Christmas tree lights. You can...

How to drive up the voltage from low voltage wind generators. This can be useful to make the generator "do" someting. Usable for a garden light or 1,2 V battery charge circuit (3 mA at 1,2 V with a bridge rectifier and a 6 V bicycle dynamo with a horizontal windmill).

This shows how a cheap stepper-motor can be used as a generator for lighting LEDs. The shaft of the motor is chucked into the lathe, which is spinning at around 800 RPM. The camera sensor artifacts show the two LEDs flashing alternately- I hooked them up in parallel, but with...
