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 Innovation Management Solutions of Santa Maria, Calif.
