Bucky Batteries are power generators built around a man-made radioactive core with a half-life of 91,634.4 years. The core is constructed by generating short-lived rare earth metal atoms inside buckyballs made from radioactive silicon isotopes. The steric and ionic forces of the buckyball extend the half-life of the metal. The battery’s hardware converts radiation into useable energy. They are inefficient to produce, less than a 10th of the initial energy cost will be released as radiation. They tend to be large; the battery in deep space buoys has a mass of 36 metric tons and produces 144 kilowatts a day.

A few alternate wide spread uses for them:
-Gravity plating on starships: A nice emergency back up to keep gravity functioning at .3-.6 G's or so during a catastrophic system failure. While far from earth normal being able to move about normally allows crews to better effect repairs then attempting to maneuver in zero gravity.
Atmospheric terraforming equipment Perfect to run the gargantuan terraforming installations on uninhabitable worlds, as these batteries take very little maintenance, and will operate the terrafomring equipment reliably for the 100+ years it takes to turn a plant habitable. (and keep it that way.)
Escape pods: While not generally the primary power supply, a bucky battery can provide sufficent power to a cryo capsule and maintain it's functionality for immense time spans, perfect to allow ample time for the pod to be rescued, or travel as slower then light speeds to an inhabitable planet. (Something that could take decades if not centuries depending on the location it is launched from and end velocity.)
