My idea is to supply light using optic fiber instead of the electric wires to save the energy. As we all know that when electricity travels through wires, it loses its power (potential difference). Hence we lose lots of energy when electricity travels from the power station to our home. My idea is very simple... here are the steps: 1) Generate laser rays (or other high intensity rays) at the power station and supply it to home via fiber optic. Light loss will be less than 1% in fiber...
