After watching on the green tips and electricity free exercise this week on The Biggest Loser, I got to thinking (always a dangerous activity). Why don't we generate electricity from our exercise and make that pedal power turn into actual power?
Well, somebody asked that same question and created a answer. Windstream Power, renewable energy pioneers, have actually created some ways to recapture your energy. My favorite is the Human Power Trainer that combines an indoors bike trainer with a permanent magnet DC generator, which is placed under the back wheel. The friction created by the motion of the back wheel produces electricity in the generator. The amount of electrical power generated is determined by the weight (friction is part of the equation, remember) and strength of the cyclist.
While a cycling pro can create 300 watts at a sustained rate, it is estimated that the average person can generate about 150 watts. The entire system costs a pretty penny though and you can expect to pay $595 for the Human Power System and additional amount for the portable power pack. But think about the motivation: recoup losses by creating your own electricity and burn some calories.
