Uranium that's been depleted isn't necessarily waste, according to researchers at Nottingham University. They think—besides making ammo and tank armor—it could be used as the basis for future hard drives thousands of times larger than current ones.
You see a molecule comprised of two Uranium atoms has magnetic properties at low temperatures, making the element ideal for a super dense hard drive. Referred to as a single-molecule magnet, this possible application for Uranium wouldn't pose any safety threats because any radioactive properties would be absent. All of this is still in the infant stages of the research project, but imagine being able to store the capacity of today's data center in a single desktop drive. Awesome, right? [Futurity]
