Create ecological gyms in which all appliances (bike, tapes running, rowing ...), which are connected to the same mechanism which collects all the energy carried out by the physical effort of each person, and transform it into electricity to supply a portion of the energy used in the streets (lights, traffic lights ...) and thus create a pure energy of every citizen and not the Earth itself, as we so far and that more and more exhausted.
