In the 1890s two major inventions came about, both of which we cannot do without every day. One is the telephone and the second is electricity. A hundred twenty years later we still continue to use these products. The phone changed to become wireless and the world has saved many million tons of copper that went into making millions of miles of telephone cables in the earlier days. Although, we continue to have landlines and optic fiber cabling, the quantum of such cabling has come down very dramatically. Can the same happen for electricity where it goes wireless? The next big game changer in the world after wireless telephones, will be wireless power. Who will be that inventor who will make $1 billion on this invention?
