Small Reactor for Deep Space Exploration

Neat! Small Reactor for Deep Space Exploration: http://www.youtube.com/watch?v=KobRfGqlpGc&feature=youtu.be "This is the first demonstration of a space nuclear reactor system to produce electricity in the United States since 1965, and an experiment demonstrated the first use of a heat pipe to cool a small nuclear reactor and then harvest the heat to power a Stirling engine at the Nevada National Security Site's Device Assembly Facility confirms basic nuclear reactor physics and heat transfer for a simple, reliable space power system."
