Abstract
Since the late 1960s, there has been interest in the United States, and later in other
nations, to capture solar energy in space and efficiently transmit it back to Earth. Starting
with his seminal paper in 1968, Dr. Peter Glaser began architecting a prototype system that
was further explored by the US Department of Energy in the Concept Development and
Evaluation Program. This initial study showed that the project was very ambitious and
fraught with technical, social, and economic uncertainties. Energy economics and the lack of
a reliable, high frequency space launch capability brought most research to a halt in the
1990s. This paper proposes a rational technical strategy to refocus Solar Power Satellite
(SPS) research. It suggests a 30 year timeline for program milestones and analyzes potential
technical performance. Real options analysis is used to manage uncertainty and permits the
exploration of possible futures that are dependent on launch costs and electricity market
prices. We propose that the U.S. can make progress toward implementing a small scale SPS
system within several decades if work is begun now on technology development and on
addressing societal concerns.
