Keeping FIT (not FiT)

FIT as in Fitness folks, not as in Feed-in Tariff.

Driving to work, I passed a fitness gym - all those people running, rowing, cross-training etc - Phew! It's enough to wear you out just watching. A good job I was sitting down I can tell you.

(mind you, the old 'clutch leg' gets plenty of exercise on a routine commute...)

Anyway it got me thinking (dangerous I know) - what if all the gyms had their training equipment hooked up to some form of motor/generator, which produced electricity?

All that energy being expended - surely it must be capable of powering at least the water coolers or the juicing machine?

Hamster-hybrid energy anyone?
