||Electricity generation with human footsteps
The use of human-power in more efficient manner for generation of electricity has been possible due to modern technology. pedal power is an excellent source of energy, 95% of the exertion put into pedal power is converted into energy . A a human-powered electricity generator has been unveiled by a company . In this apparatus, the user has to push up and down with foot on a step-action treadle for generating power. Another one is a foot-powered device that allows individuals to pump out power at a 40-watt clip to charge its own internal battery. Then this battery can be used for powering AC and DC devices, car batteries etc.
A notable approach is to have everyone have magnets in their shoes and all the paving slabs had inter-connected coils cast inside. electricity can be generated whose amount will depend on the number of people travelling.
A "Crowd Farm" has been setup by MIT students for producing electricity from the energy of pounding feet in crowded places. A populous country like india can look forward to it. railway stations, bus stands, airports, temples or rock concerts all can potentially produce electricity.
