Overview

In an era marked by the urgent need for sustainable energy solutions, this book offers a compelling vision of the future. Space-based solar power, long a dream of science fiction, is now within the realm of possibility. The technological innovations described herein, such as advanced solar cells and electric propulsion, have the potential to revolutionize not only our energy infrastructure but also space exploration itself. Investing in SBSP is not merely a pragmatic step toward a cleaner future; it's an investment in our innate human drive to explore, innovate, and transcend limitations. This report, prepared for NASA, estimates the costs and greenhouse gas (GHG) emissions of two proposed space-based solar power (SBSP) systems, comparing them to terrestrial renewable energy sources. The study considers two designs: the Innovative Heliostat Swarm (RD1) and the Mature Planar Array (RD2), both operating in geostationary orbit (GEO) and delivering 2 gigawatts of power to Earth. The study finds that launch and manufacturing costs are the primary drivers for both systems, making them significantly more expensive than terrestrial alternatives. The baseline assessment suggests that SBSP might have lifecycle costs per unit of electricity that are 12-80 times higher than terrestrial options. However, the study also highlights potential cost reductions through technological advancements and operational efficiencies. These include reduced launch costs, improved solar cell efficiency, efficient manufacturing at scale, extended hardware lifetimes, and the use of electric propulsion for orbital transfer. This annotated edition illustrates the capabilities of the AI Lab for Book-Lovers to add context and ease-of-use to manuscripts. It includes several types of abstracts, building from simplest to more complex: essays to increase viewpoint diversity, such as Grounds for Dissent, Red Team Critique, and MAGA Perspective; page-by-page summaries and notable passages; and The Seven Most Important Passages.
