It was Nikola Tesla, who first proposed there was unlimited energy that could potentially be tapped and beamed to earth from the ionosphere. In a different twist to a similar concept, there’s an article on Space.com about the potential to build huge solar satellites that orbit the earth and beam energy to us via microwave technology. Of course, billions of dollars would need to be spent on r and d and infrastructure, but as the article points out, we’re already spending billions securing our oil in the Middle East, and the prospective cost of global warming could be even more.
