dear all,
This is just a budding idea, Can we not geerate electric power form
gym equipm. like the bicycle, and the tread mill,
all that energy goes waste into friction?

problem is the storage of the power into batteries- they ae both
expensive and wasteful over time, toxic as well,

but what abt storing it as compressed air potential energy, which can
then generate electric power using a small generator as and when
required.
Is there any prototype of this kind?
