Cabrillo College Bicycle Generator

This demonstration is very effective at giving students an idea of what 100 Watts "feels like". It also illustrates the difference between incandescent bulbs and compact fluorescent bulbs. An inverter circuit allows it to also power 120V AC appliances. Many thanks to the Pedal Powered Desk Team at UC Davis for ideas and circuit help.
