NASA's kilopower small scale nuclear reactor for space missions [pdf]

I find the concepts in this reactor to be pretty awesome, and the word is they are going to be testing one at the Nevada Test site so its more 'real' than a lot of conceptual small scale reactors.

At 10kW it would be a fun way to have free power for life in your typical urban single family detached home :-). 10 of them could power the ISS without solar panels.
