John Bucknell, CEO of Virtus Solis Technologies, provides a comparison of space-based solar power reference designs and their economics.
The U.S. White House Office of Technology, Policy and Strategy has released its long awaited study on Space Based Solar Power. According to the Executive Summary, “This study evaluates the potential benefits, challenges, and options for NASA to engage with growing global interest in space based solar power.” From the conclusion: “Our first-order assessment has shown that two notional SBSP systems, using existing or near-term technology, are very expensive but may produce GHG [greenhouse gas] emissions comparable to existing renewable electricity production technologies. Some major drivers of cost and GHG emissions for SBSP include launch, space hardware manufacturing, disposal of massive satellites, and in-space assembly of large systems. However, our sensitivity analyses demonstrated that there are ways to significantly drive down the cost and emissions of SBSP systems.” *** Peter Garretson provides commentary in The National Interest
