After languishing in limbo for most of the last year, EMC2 Fusion Development Corp. says it’s back in business with an unorthodox concept for nuclear fusion power plants.

The concept is variously known as Polywell fusion, inertial electrostatic confinement or magnetic cusp confinement..

If anyone ever finds a way to harness fusion – the reaction that powers the sun – it could usher in an era of low-cost, plentiful, relatively clean energy. Lots of research teams are trying to do it, ranging from the international ITER consortium to private companies such as Lockheed Martin, Tri Alpha Energy, General Fusion, Helion Energy, LPPFusion and EMC2. So far, no one’s produced a net gain in energy.
