Want to start a space colony? Even if you don’t, space agencies across the globe do. Whether it’s a moon base now, à la the Trump administration’s plans for NASA, or a Mars landing later, such a colony will need a lot of power. And given the possibility of light-obscuring dust storms on the Red Planet and the moon seeing an uneven amount of sunlight, solar panels may not cut it. But don’t worry — Los Alamos National Lab has a plan.
