Researchers at the University of Missouri have developed a prototype of a water-based nuclear-powered battery. This battery lasts longer and works more efficiently than conventional batteries, and could be used as a dependable source of power in vehicles, spacecraft and other applications that demand maximum reliability, longevity and efficiency.

The nuclear-powered battery provides an electric current by passing high-energy beta radiation through platinum and titanium dioxide to create an electron flow.

Even though this battery is nuclear-powered, it is not dangerous as it uses controlled nuclear technology, the likes of which is already used in things like fire detectors and emergency exit signs.

This is not the first nuclear-powered battery, but is in fact the first to use radiation-assisted splitting of water to produce an electric current.
