This business would be about energy capture.  Ever been to a spinning class at a gym?  I noticed that there is so much energy created by those bikes during the course of a class.  Once the class is over, the energy is gone.  The idea would be to create an attachment to the bike to capture the energy.  Then, that energy could be used to help power the gym or small appliances or other things.  Once energy like this is harnessed, there are multiple applications for it in the gym and in other places where energy is created by people but never captured.
