The most revolutionary concept is an effort by Lockheed to develop small-scale nuclear fusion reactors. Lockheed hopes to build a working fusion reactor within five years, and to commercialize the concept soon after. Lockheed’s concept involves using nested containment systems to confine and control the plasma in the reaction chamber. Unlike competing fusion concepts involving massive facilities, Lockheed claims that their reactor will be small enough to place on a truck. If Lockheed is successful, they will finally deliver on the promise of cheap, plentiful and environmentally safe nuclear energy.
