Diamond Batteries Made Of Nuclear Waste Can Generate Power For Thousands Of Years

A severe downside of this process is the creation of dangerous radioactive waste, which ultimately deposits in the graphite core that it is housed in. Today, this nuclear contamination is safely stored away until it stops being radioactive…and with a half-life of 5,730 years, that takes quite a while.

The scientists found a way to heat the radioactive graphite to release most of the radioactivity in a gaseous form. The gas is subjected to high temperature and low pressures that turn it into a man-made diamond. When these diamonds are placed near a radioactive field, they generate a small electrical current. The developers enclosed the diamond battery in another non-radioactive diamond to absorb the harmful emissions, which in turn allowed for the generation of even more electricity, making the battery nearly 100 percent efficient.
