Remember Batman and Robin? Specifically how Mr. Freeze’s subplot involved him having to steal diamonds to make his suit work? Well that plot point may actually work better now. Scientists at the University of Bristol are looking into a way to turn old radioactive carbon into diamond batteries.
The carbon comes from a retired nuclear power plant. Carbon-14 isotopes, which are VERY radioactive are removed from the rods to make them them safer (and cheaper) to store until they revert back to normal carbon. This will take thousands of years. The harvested carbon can be made into a special diamond that is a little power source all on its own. A battery that will last for thousands of years.
The diamond can be used for space or medical devices where changing the battery just isn’t feasible. This is still in the research and testing phase. The implications of it are wide but honestly, can you imagine having a phone that never needs to be charged? Check out the video to get the full overview of the process.
