" 5,000yrs of battery life: Nuclear waste-formed radioactive diamonds provide long-lasting energy

Scientists have discovered a way to convert nuclear waste into radioactive black diamond batteries which last more than 5,000 years.
Researchers at the University of Bristol have found a means of creating a battery capable of generating clean electricity for five millennia, or as long as human civilization has existed.

Scientists found that by heating graphite blocks – used to house uranium rods in nuclear reactors – much of the radioactive carbon is given off as a gas.

This can then be gathered and turned into radioactive diamonds using a high-temperature chemical reaction, in which carbon atoms are left on the surface in small, dark-colored diamond crystals.
