For decades scientists and engineers have talked about using the dusty lunar surface to manufacture solar panels. The key advance made by Blue Alchemist is that its engineers and scientists have taken the byproducts of this reaction—and these materials alone—to fabricate solar cells as well as the protective glass cover that would allow them to survive a decade or longer on the lunar surface. While it is a long way from lab experiments to manufacturing on the Moon, these experiments are a critical first step
