Energy supply from gym workout
|
It is estimated that the average person produces up to 300 watts of electricity during a workout session - enough to power a washing machine for an hour. Scientists at Stirling University are working on a grid that can harness electricity from exercise bikes, rowing machines, treadmills and cross-trainers and use it to power the gyms themselves or even light up hotel bedrooms and kitchens.
Researchers Tao Pei and Emmanuel Pogoson's system would store electricity in a similar way to wind farms and wave machines. Gym equipment would be attached to generators or a central power source that could convert kinetic energy from movement into mechanical energy. Is it possible that no one had thought about it before?

I have been thinking about this for some time. Most cardio machines use electrical generation as a means of creating resistance in the mechanism (sort of like regenerative braking) this energy could be shunted to storage devices rather than being dissapated in load banks. In turn the energy could be used to power the TV banks or lighting or other uses. The gym member could log on and off the machines and be granted membership credits based on the number of kilowatt hours they generate during the year.

Someone else thinking about it and collecting proposals:
Notions of Expenditure
Prison labor power: convicts pedaling generator bikes. I thought it up as a satire, but it's so obvious -- so potentially profitable -- that life will probably imitate art.
The late Screaming Lord Sutch (British rock singer/leader of the Monster Raving Loony Party) had a policy in his manifesto that joggers would have to run on giant treadmills to generate power to help heat the homes of the elderly.
He never won a single election despite policies like this. :)
The writers of Gilligan's Island thought of this. :)
For an instalation piece several years ago I hooked up my racing bike to a generator and powered the exhibition. The various other pieces required electricity when being viewed or used and as such the more people interacted with the artworks the harder I had to work... The main function was to make the audience feel guilty about gawking at art... For the 2 hour show I produced an average of 300 watts with peaks into the 1200's.
