While the problem of global warming is becoming increasingly urgent, the geopolitical situation is underling the necessity of include in the Italian energetic mix sources other than oil and gas. Conversely, the public opinion is still frightened by fission technologies, forcing governments to invest in different solutions. Great efforts have been spent in nuclear fusion research and the availability of new technologies in these years (e.g. high temperature superconductive magnets) are making it appear as a credible medium-term solution. The ARC project, proposed by scientist of the MIT and PSFC is aiming to prove the feasibility of such a technology, with a grid connected reactor.
