Powerpoint only
They propose to use the Duterium-Tritium reaction, which produces a high energy neutron. They want to use lithium to capture the neutron to produce heat and more Tritium. There are so many problems with this plan!
- You won't get 100% absorption of the neutrons in the lithium, so you're going to have the building irradiated by high energy neutrons
- You need a specific isotope of lithium. Lithium is abundant, but the refining procedure is difficult.
- Lithium+neutron only produces one tritium, so you have to add tritium from some other source
- Tritium has a half-life of 12 years, there is no natural tritium. Today Tritium is available commercially from the Canadian "CANDU" reactors, as a by-product. No new CANDU reactors are being built and the existing ones are progressively being decommissioned.
So before we get to the engineering challenges, just the powerpoint presentation is not perticularly believable.
There are other reactions available, but at much higher temperatures that we can't currently hold in a Tokamack. Come back in 10 years with a better powerpoint please.
