A research team at the University of Bristol has developed a way to use a type of nuclear waste to generate electricity in a nuclear-powered battery that is an actual diamond. Such a battery produces very low power, but has no moving parts, no emissions of any type including radiation, needs no maintenance, does not need to be recharged and will operate for thousands of years. The team grew a man-made diamond that, when placed in a radiation field, was able to generate a small electrical current. And the radioactive field can be produced by the diamond itself by making the diamond from radioactive carbon-14 extracted from nuclear waste. Even better, the amount of radioactivity in each diamond battery is a lot less than in a single banana. Diamonds are made from pure carbon subjected to high pressures, usually deep in the Earth's crust. But we have been artificially making them for decades. The normal way to produce electricity is to use energy, like burning coal or capturing wind, to move a magnet through a coil of wire to generate a current. However, a diamond is able to produce a charge simply by being subjected to a radiation field. The cost to produce a diamond is a lot less than disposing of used nuclear fuel and nuclear waste. These radioactive diamond batteries would have a very specific purpose - low power and extremely long life. The ... battery would still be putting out 50% power after 5,730 years.
