WHAT A SO SO GOOD IDEA !!!!! In Portland, a "green" fitness club allows to generate electricity during clients training. They installed power generating machines just like treadmills, elliptic trainers, stationary bikes etc... and when customers are exercising to keep in shape they create electricity which is stored in battery packs. Clients can even watch on a digital display the amount of watts they are generating ! Read the article here.
This idea is just amazing and fabulous because it allows to save an energy (clients movements) which would be lost otherwise. Actually, it's a very positive synergy, making the most of the sport motivation to transform it in a different energy form !!! Now I can't see classical fitness clubs as before, they are wasting an easy and free energy ! How is it possible in 21th century ? Grrrr !
Imagine if we could do that in our houses ? Look, if you train at home, why not to load a main battery during familly trainings for a later use like loading iPods, cellphones, rechargeable batteries, for garden lights or just to use less electricity from your electricity network ?!
By the way, I'm thinking about another thing... In gym clubs, it used to be very warm inside... Normal, 80% of the energy expended during exercise is released in the form of heat. Yes, human being is in spite of him a pretty good heating system. Then, it would be a good idea to fetch this form of energy to heat up shower water (with a heat pump for example...) I guess that's a better idea than just to get rid of this precious heat to outside through conditioned air. No ?

Many places use secondary generated heat to heat up other things.
It is not very efficient to use air to heat up water but you can get up to 95% of efficiency if you use air to heat air by using any current heat recover system. No need of air conditioning. The damp air (hot) is pulled out with a fan and "crossed" with the new air (cold) so that 95% of the heat is exchanged to the new/fresh air.
Please dont ask me why dont people use this simple/healthy system more often!!! ....humans like air conditioning maybe! My father does! LOL
