I remember reading a science fiction book when I was young of people on another planet that got the power for their personal transportation and all other needs by broadcast power similar to our receiving radio, tv or wifi. I thought it was a great idea then and wondered if it would ever be possible. It would seem that at some point as we continue to learn about the piezoelectric properties and power generation of our daily earthtide, capable of generating lightning and heat around the world, that we might eventually discover a way to tap and control that energy. It would certainly wreak havoc in the battery industry. Seems like I may have heard recently about Elon Musk doing some research into something similar.
