The screws used by doctors to repair broken bones and torn ligaments enable recovery from a wide range of injuries. Unfortunately, they also leave holes in bones, require secondary surgery for removal, and make going through airport security a real pain. But by crafting the screws from a special designed composite of polymer and mineral, researchers at Germany's Fraunhofer Institute have managed to solve all those problems in one fell swoop.
Cutting through solid steel with flaming bacon certainly has its appeal, but for large-scale industrial processes, the Fraunhofer institute thinks electromagnetic pulses may work better than the other white heat. Case in point: their new electromagnetic pulse (EMP) device that cuts through steel faster than a laser, and cheaper than a machine tool.

Sleek, wall-mounted plasma screens might seem like viewing nirvana now, but what if a picture window could double as a flat-screen TV? Or what if your car´s GPS system could be displayed on your windshield? Researchers at the Fraunhofer Institute in Germany have invented a transparent OLED (organic light-emitting diode) that will allow just that, transforming any clear surface into a see-through display.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
