    I wonder how efficient it is. Let’s say the bike is 90% efficient, the pump is 70% efficient and the pneumatic power tools are 70% efficient, so you get 44.1% efficiency.

    If you give or take 10% from/to each of those, you can get as low as 28.8% efficient or as high as 64% efficient.

    If you build the electic equivalent (generator, battery and electric powertools) it is probably twice as efficient or more. Pedal for only a half to a third as long.

      Adding to this: This is basically turning solar energy in stored energy. Solar power-> growing Plants-> Man eats Plants-> kinetic energy-> storage

      Simply take a solar panel and a battery.
