If I understood the news correctly, this potential new development depends on using semi-conductors with super-conductivity. Fusion has a long history of being Brazil: 30 years away, always has been always will. If this development pans out, which we may know in as soon as 3 years, we would be 15-30 years away from viable fusion energy.
Please note that nuclear fusion is not a fantasy. Fusion reactions have been sustained on Earth for decades. What we haven’t been able to do yet is to extract more energy than needed to contain the reactions. This may change. Big MAYBE, but something worth watching.
