Are current and future space technologies favourable to SSPS projects?

This viewpoint looks at the positive and negative prospects for the establishment of Space Solar Power Stations (SSPSs) from the standpoint of the way in which space technology has evolved since the concept was first proposed. While there are pressing arguments for alternatives to today’s energy sources, and technological advances have made construction and maintenance of SSPSs potentially easier and less expensive, it is argued that the general trend towards miniaturization in space, plus the probable difficulty of obtaining frequency allocations for SSPSs, militate against their realization. Further, the increasing militarization of space provides additional competition and could mean that SSPSs will never be launched for fear of becoming an enemy target. Nevertheless, SSPSs could have a future supplying electricity within the space environment itself.
