Space-Based Solar Power: A Technical, Economic, and Operational Assessment

: The concept of generating electrical power from solar energy using satellites and then transmitting that power to Earth is decades old and generally considered to be technically feasible. If successful, such systems could provide constant access to almost unlimited power and thus play a significant role in U.S. national and international energy security strategies. However, the practical application of this method of power generation requires economical and operational feasibility as well. This monograph examines the current progress of space-based power in these three areas: technology, economy, and operations. The scope of discussion is at the survey level of detail to provide senior policymakers, decisionmakers, military leaders, and their respective staffs an overall appreciation for the challenges, opportunities, and risks associated with space-based solar power systems.
