Nasa is thinking of powering some future moon outposts with nuclear reactors.

Frankly, that makes a lot of sense, as it would not have to rely on massive solar panels and even more massive batteries to store electricity for the long lunar nights.

Apparently NASA's Glenn Center in Cleveland is looking into the matter, and are currently waiting to see which of two advanced power conversion units would be most suitable to convert the heat generated by a nuclear reactor to electricity. It is expected that a nuclear reactor the size of a garbage can could provide 40KW of electricity, which on Earth would be enough to power four houses, but would be enough for a more sizable outpost on the moon.
