Massachusetts-based Commonwealth Fusion Systems believes it can deliver a nuclear fusion machine that is small, fast to build, and could be in production and commercial operation during the 2030s, MIT Technology Review reported.

The company said the prototype of its ‘Sparc’ machine should cost hundreds of millions of dollars, rather than the tens of billions for the International Thermonuclear Experimental Reactor (Iter) in France, and take years rather than decades to construct.
