NASA Funding Satellite That Would Beam Solar Power Down to Earth

The turning point for this technology is all due to the biomimetic design that Mankins came up with, which mimics how flower petals collect solar energy. The petals would be covered with small, thin-film mirrors that could be curved to direct sunlight to solar cells. The satellite would be positioned far enough away from the Earth so that it will never be in the dark. The energy collected would be converted into microwaves that could be beamed or broadcast back to Earth where electricity would be generated. The design allows for the use of small, lightweight mirrors and solar cells so that the satellite could be constructed and transported at a not-ridiculous cost.
