Proposed Satellite Would Beam Solar Power to Earth

PASADENA, Calif. — An energy-hungry Earth is in need of transformational and sustainable energy solutions, experts say.
For decades, researchers have been appraising the use of power-beaming solar-power satellites. But the projected cost, complexity and energy economics of the notion seemingly short-circuited the idea.
Now, a unique new approach has entered the scene, dubbed SPS-ALPHA, short for Solar Power Satellite via Arbitrarily Large PHased Array. Leader of the concept is John Mankins of Artemis InnovationManagement Solutions of Santa Maria, Calif.
Mankins provided a detailed overview of the power-beaming concept here during the 2012 NASA Innovative Advanced Concepts meeting March 27-29. [Video: Beaming Power From Space]
The NIAC is under the wing of NASA’s Office of the Chief Technologist, which is providing a technology and innovation focus for the space agency.
