Turning nuclear waste into diamond batteries. 

Nuclear power is a great source of renewable energy, and while many place it in the category of clean energy, it carries a serious downside – radioactive nuclear waste. This stuff is not only dangerous, but also has a crazy long half-life (5,730 years), which makes it dangerous for  very long time. Scientists have created a way to safely harness the radioactivity, using it to power a battery. The long half-life has a silver lining, since the battery can provide power for thousands of years. | learn more
