Somehow I feel this would be rather inefficient from the energy point

But aren't you going to feed them anyway?

You'd have to feed them more. Such atheliets have specail diets too.


UK Prison population approx 85,000, a resonably fit person pedling at
a rate they can sustain ought to be able to produce about 100 W. So
8.5 MW .

Were did you get that figure I heard 80w average for an hour.


but with eating and sleeping and an 8 hour shift pattern only 1/3 of
that, at very best, would be avialable. Then there would be "un-fit"
for what ever reason perhaps you might get 25%? or about 2 MW?

I'd suggest we make it an olympic event why waste money on a velodrome
when all you really need is a bike stand and a watt meter.
Our team GB would also be doing something useful while training/practicing.

Although I'm not sure providing a certain Mr Armstrong or others with free drugs would make it economically viable.
