To piggy back on what Joel said, the CO2 that you breath out is part of a closed system. (that CO2 came from the organic material that you consume which was retrieved from the atmosphere within your life time). The CO2 that is released from burning fossil fuels to power these machines took millions of years to be sequestered into oil/coal. Releasing that CO2 is what increases the overall amount of CO2 in the atmosphere.

i am doing a school science project and i have decided to see if the gyms could power them selves by using their gym members power. i am only twelve and dont understand exactly how it works. how do you take someones energy and use it to power a lightbulb?

Very interesting read Joel. Might as well do something constructive while you exercise, right?

This website is promoting gyms that produce electricity.

The thought of generating electricity while on a commercially available exercising machine is exciting. Does anyone know of a site to find info on how to convert an exercise bike?

Good point Jeremy, but if you’re exercising anyway then you’re not adding anymore CO2 than you would have done anyway. At least this way there’s a positive by-product.

Sounds great, but what about the massive amounts of CO2 generated by the person exercising. In case you forgot high school Biology class, energy is created in humans when sugar plus oxygen is converted to CO2. It would take some heavy math to prove, but I bet a human comes pretty close to producing just as much CO2 as the article assumes is avoided.
