"Hot Tub" Nuclear Reactor Could Power Cities

About the size of a hot tub, this portable nuclear reactor in development by Hyperion Power Generation could be buried in a small cement casing within the ground and provide maintenance-free power to 25,000 homes for 5-years.

An internal chemical reaction produced 27 megawatts of thermal energy powering an external steam turbine to produce electricity. A sort of nuclear battery, we're not sure if it could, should or will ever come to fruition. But it's certainly a neat idea...and the perfect accessory to take our summer grilling "to the next level." [hyperion via sfreporter]
