Working Nuclear Fusion Reactor by 2022

Lockheed Martin :
"Lockheed’s proposal is enticing due to the fact that it is far smaller than other fusion reactor designs. The plan uses a compact cylinder, rather than the traditional bulky ring, which provides a far stronger magnetic containment field and leaves fewer points where energy can escape. Lockheed plans to start testing a prototype model in 2017, and scale it up to a full production model by 2022."
