Barry's Bike Generator

Basic "training stand" design, with generator simply clamped against bike tire quick facts from Barry:  in our system a person could produce 60-100W continuously with reasonable effort and 200W at a sprint.  We tried to make a bike wheel into more of a flywheel by adding concrete- sucked.  The final configuration just powered a 110VAC cigarette lighter inverter.  Very easy to demonstrate typical appliances.. as long as they don't care about being turned on and off. Unfortunately, it was difficult to pedal at just the right pace required by whatever was hooked up. This is because of the over and under voltage cutouts settings on the inverter; if you pedalled too fast, power was cut off, and if you pedalled too slow, same thing. Some experimental data gathered by Barry and friends with their bike:
