What if the Moon's natural defenses could also power our bases?
Scattered across the lunar surface are invisible force fields called mini-magnetospheres. They shield against solar wind radiation. AND they MIGHT also generate electricity.
With funding from DARPA, Professor Justin Little and Ph.D. students Patrick Rae and Arvindh Sharma are testing this idea in A&A's SPACE Lab.
Rae built a miniature Moon in a vacuum chamber, complete with a "big little flashlight" that fires krypton plasma at 50 km/s to simulate solar wind. (Yes, krypton, as in Superman's home planet.)
Meanwhile, Sharma runs simulations on the Hyak supercomputer to predict how these magnetic bubbles behave under the strain of power extraction.
When solar wind hits these magnetic anomalies on the Moon, electrons get caught while heavier ions push through. This natural separation creates 100-500 volts, which is essentially a battery. The challenge is turning that voltage into usable current.
The team's solution is to inject electrons to boost the flow from "a stream into a river."
Lab experiments have already confirmed the concept works. The next step is proving it's practical on the lunar surface.
