The High Frontier, space based solar power, and space manufacturing

Abstract

The author discusses a book named The High Frontier by Gerard K. O’Neill, which published in 1976 and provided a vision of space colonization and economically profitable habitats. The book forecasted that space communities could be established within 30 years, arguing this would be supported by space solar power and space manufacturing. The author points out several reasons why those predictions were incorrect, including overestimation of the benefits of space solar power and the underestimation of the costs and challenges of space colonization and manufacturing. While conceding that subsequent improvements in launch costs and solar technology have made space-based solar more plausible, the author argues that it remains inferior to terrestrial solar in terms of cost-effectiveness and scalability. – AI-generated abstract.
