Comment Fusion != Radiation Free (Score 1) 315
According to the comments in the article this is based off of Deuterium, Tritium (D-T) fusion (which is the easiest to do). 80% of the energy from D-T fusion is in the form of high energy neutrons. The neutron flux is 100 times more than in conventional fission reactors which causes high levels of radiation in the vessel containing the fusion ( fusion vacuum vessel too hot for one year").
Tritium is not plentiful on this planet, so one solution that may solve both the high speed neutron energy capture and the breeding of Tritium is to surround the D-T reaction with Lithium which will 1) absorb the neutron's energy, and 2) create Tritium and Helium from the Lithium. So now we have electricity storage (Lithium batteries) and electricity generation (D-T fusion) bottle-necked by the same element: Lithium
Note that Tritium is radioactive and could leak or experience containment issues.
I am not so certain this will solve anything that current generation fission reactors don't solve just as well, except marketing / branding: I think selling the people on a fusion reactor in their backyard is easier than the fission one.
