Centrali solari orbitanti entro il 2041.

Anche se sembra fantascienza ha già ricevuto premiato al concorso della NASA Innovative Advanced Concepts (Niac). È la centrale solare orbitante Solar Power Satellite via Arbitrarily Large Phased Array (SPS-ALPHA) progettata da John Mankins (Artemis Innovation Management Solutions). Il progetto, erede di un'idea di 40 anni fa, consiste in un campo di specchi mobili in grado di intercettare e reindirizzare la luce solare in verso le celle fotovoltaiche posizionate sul satellite artificiale per produrre da 10 a 1000 MW.

John Mankins (Artemis Innovation Management Solutions): "SPS-ALPHA (Solar Power Satellite via Arbitrarily Large Phased Array) is a novel, bio-mimetic approach to the challenge of space solar power. If successful, this project will make possible the construction of huge platforms from tens of thousands of small elements that can deliver remotely and affordably 10s to 1000s of megawatts using wireless power transmission to markets on Earth and missions in space. The selected NIAC project will enlist the support of a world-class international team to determine the conceptual feasiblity of the SPS-ALPHA by means of integrated systems analyses, supported by selected "proof-of-concept" technology experiments"
