Open Image…Save ImageOpen Image (using #TmpD/ia)… The Caltech Space Solar Power Project (SSPP) prototype launched into orbit, dubbed the Space Solar Power Demonstrator (SSPD), will test several key components of an ambitious plan to harvest solar power in space and beam the energy back to Earth. Space solar power provides a way to tap into the practically unlimited supply of […]

Scientists at the Japan Aerospace Exploration Agency (JAXA) have a plan underway for a 1-gigawatt space-based solar power generator within just 25 years. JAXA is working directly on the main problems. Orbital solar power’s main problem is once the energy is harvested all the huge reservoir of energy is still out there in space. Early […]

NASA’s Innovative Advanced Concepts (NIAC) program has started a Phase I effort to explore the overall viability and advance the Technology Readiness Level (TRL) for an orbital power station project called “SPS Alpha”, or Solar Power Satellite – Alpha. Last August, Artemis Innovation Management Solutions was selected for a NASA NIAC award to dive into […]

Carl Peart of New Mexico has a very different take on the electro mechanical battery (EMB) – solve the inherent problems of friction with air and bearings – by using them in orbital power stations.  No air or gravity, only centrifugal forces for drag. An EMB (a technical description of a flywheel) stores energy through […]

Late last week after a 6 ½ month wait, the California Public Utilities Commission approved Pacific Gas & Electric’s power purchase agreement with Solaren. If Solaren successfully deploys its space-based solar collectors, the deal would be the first of its kind and the first commercial space based energy production at commercial scale. PG&E has contracted […]
