The U.S. military’s power demand is exploding. The planet’s carbon budget is collapsing. And one technology could help fix both.

Space-based solar power (SBSP) and prospects for the development of alternative energy in orbit

We’ve written about this before—operational energy and its fragility, power beaming and DARPA’s laser programs, space industrialization and humanity’s future beyond Earth. This is where those threads converge. SBSP isn’t science fiction anymore. It’s the most consequential dual-use technology of the 21st century—a clean-energy revolution and a military logistics revolution.
