If that were given to the solar and other clean energy industries, the world could enjoy a carbon-free future very easily. This is not idle conjecture… it’s the result of a study by MIT. So why isn’t it happening? (3 guesses……
Background For several years engineers and scientists have been developing the means to beam utility electric power from space to earth. The method is to have massive arrays of solar panels floating in space 36,000 miles above the earth, converting the sun’s rays into power and beaming it to earth as microwaves. The receiving station…
