For people who wonder how this works, I'll simplify it more than I did in my comment on Spike Viper's video. A: Titanium. Sturdy, not pressure-affected, heat-resistant. Tungsten: Very heat resistant (3000C didn't melt it), very pressure weak (1 pressure = broken metal). PTCT/NTCT: 100C cooling per second as a single pixel. Very stable. Average strength, I guess.
Not that protective against the right amount of plasma.
this would be amazing for really hot reactors
