Mobile Pedal-Powered Generator

As our entry for the Innovate or Die contest, we've built a bicycle-powered electric generator capable of charging multiple electronic applications while on the go. Using a simple switch, the system can be turned off by the rider while in motion, thus disabling the electrical system and eliminating the generator shaft torque. The entire device is mounted on a standardized and easily removable bike rack, allowing users to easily move it from one bike to another. The system can produce about 120 watts, enabling it to charge either two laptops or about 4 iPods or cell phones simultaneously. No major modifications were made to the bike during installation.

What's the definition of a "life" then? Having fun and being creative while building an innovative source for electricity is pretty much of a "life" to me..

I made one like that in 1984 using angle irons and 4 wind shield wiper motors mounted on a bike rack. Drive wheels were cut from a closet dowel. It was raised and lowered by a dowel wheel/machine screw combo. For the bike stand I used a 2'x4' plywood, a 4"x4"x8" wood for the bottom bracket and 2 support wires. (It helped to have worked at a lumber yard/hardware store at the time!) I got 12 Volts and 8-10 Amps to charge a DEAD car battery in 20 min of pedaling.

genious fellas pure and simple, I love it!! How bout put the bike on a stationary setup and charge deepcycle batteries would that work?

WOW this is from 2007 and i been thinking about this for a while , anyways , perhaps something like this could be used to power an electric bike ! ...

Energy sources without the need for fuel or energy input exist ,But the powerfull Oil business won't alow common ppl to know this,Find this technology at LT-MAGNET-MOTORdotCOM ,Be a part of the energy revolution!

@justliketolook just get a generator and wire it into your light and you won't need batterys

Hi Kevin ,I would like to attach and small generator to my bike wheel that will recharge 2 or 4 AA rechargable batterys that light a led bike headlight .So I don't have to worry about the batterys going dead. Something that will keep the batterys at full charge. I can't find a rechargable bike led headlight that can be connected to a small generator that recharges.I've seen bike led headlights that have small hand cranks built in but I don't want to stop and crank to recharge batterys.
