The Case for Space Solar Power

This book makes the Case for Space Solar Power; recounting the history of this fascinating concept and summarizing the many different ways in which it might be accomplished. It describes in detail a highly promising concept – SPS-ALPHA (Solar Power Satellite by means of Arbitrarily Large Phased Array) – and presents a business case comprising applications in space and markets on Earth. The book explains how it is possible to begin now with technologies that are already at hand, while developing the more advanced technologies that will be needed to deliver power economically to markets on Earth. The Case for Space Solar Power concludes by laying out a path forward that is both doable and affordable: within a dozen years or less, the first multi-megawatt pilot plant could be in operation. Getting started could cost less than $10 million over the first 2 years, less than $100 million over the next half dozen years.

Given that Space Solar Power would transform our future in space, and might provide a new source of virtually limitless and sustainable energy to markets across the world, the book poses the question: why wouldn't we pursue Space Solar Power?
