Meeting Bob Redell in Prison

The Prison Interview A Convicted Engineer Stratt and Grace visit Auckland Prison in New Zealand to meet Bob Redell, a solar engineer serving a life sentence for embezzlement and negligence that caused seven deaths. Redell explains his blackpanel concept: a simple, scalable device that uses solar heat to breed Astrophage. He argues it can produce the needed two million kilograms of fuel. The Idea's Potential Redell's design is rudimentary but brilliant: a black anodized foil under glass, heated by the sun. The Astrophage would breed in the carbon dioxide-rich environment. Grace recognizes the genius: it trades efficiency for scalability. The Sahara Desert, with its vast area and intense sunlight, is the perfect location. Stratt's Decision Stratt, despite her distaste for Redell's character, sees the potential. She drafts him into the project, using her authority to extract him from prison. Redell becomes the manager of the Sahara Astrophage Farm, a massive industrial operation that eventually produces the fuel needed for the Hail Mary.

Building the Sahara Farm

Industrializing the Desert Global Industrial Effort Stratt mobilizes the industrial capacity of China, India, and other nations to produce blackpanels. Millions of square kilometers of the Sahara are covered with these devices. The project is the largest human construction ever, visible from space. The environmental impact is severe, but it is a necessary evil. Weather and Climate Effects The blackpanels alter the local climate, causing unexpected weather patterns. Dr. Leclerc warns that the heat redistribution from the Sahara will disrupt global weather. Stratt ignores these concerns, prioritizing fuel production. The blackpanels become a symbol of humanity's desperate gamble. Success and Consequences The farm successfully produces the required Astrophage. However, the ecological cost is immense. The Sahara's albedo change contributes to the chaotic climate that Leclerc predicted. But the fuel is ready, and the Hail Mary is launched. Redell's gamble pays off, but it is a Faustian bargain.
