  Hey guys could we use exercise machines for generating energy?
  Please support your ideas with the pros and cons of it.

  Yes, we had a discussion about using the machines in the gym to power the gym itself. But it seems that the overall energy generation through exercise machines isn't really enough to satisfy the energy needs of the gym.

  How about increasing the output by using gears of different sizes and increasing the output. Like in the case of by-cycle when you pedal you rotate the larger gear wheel ('m' times) and which in turn rotates the smaller gear wheel by 'n' times where (n>m). similarly if the total output is converted in such a way then the energy generated can be increased..

  at least the energy generated could be used to charge your battery (car/inverter) or to run any small power consumption devices..

  These are commercially available @ about US$600 for a 100w generator. However, one can only expect about 50w on a sustained basis. Age is also a major factor.
