Nikola Tesla Quote

We have to evolve means for obtaining energy from stores which are forever inexhaustible, to perfect methods which do not imply consumption and waste of any material whatever. I now feel sure that the realization of that idea is not far off....the possibilities of the development I refer to, namely, that of the operation of engines on any point of the earth by the energy of the medium.
