Piezoelectric plastic sheet system for rapid transit platforms

The problem with renewable energy production is that it requires large operational area and doesn't produce much electricity but one potential source has largely been neglected, that is us the human beings.

London Undeground has a footfall of 3.5 million per day, Delhi Metro has 2.6 million per day and Hong Kong MTR has 4.5 million per day they are also many other rapid transit across the world. Considering that in mind the platform on this station is walked upon everyday these steps could be converted into electricity through piezo generator.
Mass Transit System are used in most major cities throughout the world and the station platform are always bombarded with footfalls, Polyvinylidene fluoride system can be used to convert the mechanical stress into a electric current.

The idea is to have a Polyvinylidene fluoride plastic generators placed on the station floor covered by a protective layer. This system will convert the stress of the footfall into electrical current which can be transmitted through the wires placed near the track to a central transformer which would in turn be feed to the central power station.

Piezoelectric plastic does not produce a large amount of current but collectively all the stations of a rapid transit system converting millions of footfalls would multiple the production many times resulting in a significant amount of energy.

The beauty of this system is it doesn't require a separate area for establishment in can be installed in the city itself with very little modification. And the Annual ridership of London Underground of 1.1 billion is a massive sustainable source of power.

This system is completely environmental friendly it doesn't require burning or produce any sort of pollution.
