This one may make you speechless. It is so obvious in its idea that you wonder why no one else has thought of it before, yet it sounds like a plot from a 1960s science fiction movie: Collect solar energy in space, convert it into radio signals, send it down to Earth and change it into electricity.
We hear about new innovative ways to create electricity in alternative, more environmentally friendly and more efficient ways at least a couple times every week. PG&E is a hot candidate for the prize for the most adventurous way so far: The company wants to provide solar power that has been sent from a satellite to Earth.
According to a company
blog post, PG&E has contracted a Southern California-based Solaren, to deliver 200 megawatts of power within a 15 year period through Solaren’s satellites. Those satellites act as small solar power plants, convert it into radio frequency, send it to a base station on Earth, where it is converted to electricity.
