The researchers realized that they could extract the radioactive carbon-14 molecules from the graphite blocks used in nuclear reactors, the part of a plant where the nuclear reactions take place to generate electricity. These graphite blocks are used to ensure the stability of the reactor, but as they’re used in the crucial area where reactions take place, dangerous carbon-14 molecules collect on their surface. Researchers found that the radioactive molecules were close enough to the surface that they could be extracted from the block. The radioactive molecules can then be used to create diamonds, which are also made of carbon. The graphite blocks, with less radioactive elements, are then safer to store.

“Carbon-14 was chosen as a source material because it emits a short-range radiation, which is quickly absorbed by any solid material. This would make it dangerous to ingest or touch with your naked skin, but safely held within diamond,no short-range radiation can escape. In fact, diamond is the hardest substance known to man, there is literally nothing we could use that could offer more protection,” said Dr. Neil Fox from the School of Chemistry.
“This is a great example of where the U.K. could literally make value from waste,” Tom Scott, professor in materials in the University’s Interface Analysis Centre, told Digital Trends. “In the U.K. we have some 95,000 tonnes of irradiated graphite nuclear waste arising from the early test reactor programmes, Magnox and the current AGR fleet.”
Scott added: “We envision these batteries to be used in situations where it is not feasible to charge or replace conventional batteries. Obvious applications would be in low-power electrical devices where long life of the energy source is needed, such as pacemakers, satellites, high-altitude drones or even spacecraft."

“Star Trek” introduced the world outside of rocket science circles to the concept of warp drive – the propulsion system that allowed the starship Enterprise to travel faster than the speed of light. Warp speed is the holy grail that would let us explore the universe safely surrounded and protected by a space-distorting warp field. After watching the SpaceX rocket recently just try to land on a platform, you’d think this ability is years if not decades away. Yet the buzz on space websites is that NASA may have accidentally discovered a way to create a warp field. Wait, what?
