What if we had satellites orbiting Earth that would provide us with energy by harvesting it up there and beaming it down here? Former NASA engineer and now CEO of Artemis Innovation Management Solutions, has come up with a scheme to do just that. NASA is very intrigued with the idea and will fund the project.

The concept is called Solar Power Satellite via Arbitrary Large Phased Array (SPS-ALPHA). The satellite would essentially be an array of thin film mirrors that would redirect sunlight toward photovoltaic panel, which would convert it into microwaves. The microwaves are then beamed down to the power plants below, which would convert them into electricity for redistribution. Something like this could very easily be built right in space with components carried by cargo ships, which would be much more cost effective than building it down below and launching it into the orbit.

 If this project is successful, how will it impact the environment? Sure, a renewable source of energy is never a bad thing, but could the microwaves have a negative impact on the ozone layer? If the latter isn't an issue, then that is definitely worth pursuing.
