Nuclear power on the moon: Rolls-Royce unveils reactor mockup

The U.K. tech giant Rolls-Royce has unveiled a concept nuclear reactor that could power a future outpost on the moon.

The mini reactor, which appears to be about 3.3 feet (1 meter) wide and 10 feet (3 m) long, is not yet capable of producing any electricity, and it will take about six years and a few million dollars to get it ready for its debut space trip, if all goes according to plan.
