Metallurgical engineer and science fiction author David Kagan discusses his novel "Sunstroke" and the real NASA/Department of Energy Solar Power Satellite Project that inspired it. Kagan, who has worked on classified projects including stealth bomber and fighter jet development at Edwards Air Force Base, explains how massive space-based solar collectors could beam energy to Earth via microwave transmission. The proposed satellite system would measure three miles wide by six miles long, generating 5,000 megawatts of power equivalent to five nuclear power plants. The conversation explores both the tremendous potential benefits and catastrophic risks of beaming concentrated microwave energy from space to receiving stations on Earth's surface. Kagan details the enormous engineering challenges of constructing such massive structures in orbit and the precision targeting required to safely deliver concentrated energy beams. The discussion examines potential disaster scenarios if the microwave beam were to miss its target, be deliberately misdirected, or be weaponized for military applications. Kagan draws from his technical background in aerospace materials testing and experience with classified military projects to analyze the realistic capabilities and limitations of space-based power systems. This episode blends hard science with speculative fiction to explore humanity's future energy needs and the transformative technologies that might meet them.
