“It should be borne in mind that electrical energy obtained by harnessing a waterfall is probably fifty times more effective than fuel energy. Since this is the most perfect way of rendering the sun’s energy available, the direction of the future material development of man is clearly indicated. He will live on “white coal.” Like a babe to the mother’s breast will he cling to his waterfall. “Give us our daily waterfall,“ will be the prayer of the coming generations. Deus futurus est deus aquae deiectus!”

–Nikola Tesla
