Clarify.

yes you are right we can produce electricity through potato also.I had seen in science exhibition.

But electricity can not be produced from non conductor substances like plastic and wood . Infact these can be used in the process of generating electricity.

Isha in future they may experiment on this also as sources are going down slowly.

If there is a will, there is a way. Nobody has tried such ways. If we try, it may succeed

scientists are doing various experiments to find out alternative resouces of energy which are renewable and eco friendly as well...its indeed the need of the hour
