Nuclear fusion / free energy impact on BitCoin?

It seems a British scientist claims to have solved the issue of being able to harness energy from fusion without "spending" more energy / money on the process itself (i.e. figured out a way to provide a net energy gain).

If this is true and there was an energy revolution (free energy) - what impact do people think this would have on the value / popularity of bitcoin?
