Seeking novel ways to produce power in space to boost power in spacecraft, and to deliver power to Earth, the Defense Innovation Unit (DIU) is soliciting proposals for space-based utility solutions that would generate electricity and beam it where needed. Space Power Beaming (SPB) could help overcome existing on-board power limitations that in turn limit technologies existing spacecraft can leverage, DIU said in a July 15 notice. Generating power in space that can be transmitted to Earth would limit infrastructure…
