What do you make of this?

As I understand it, the problem is not the working cooling molten salt breaking down, it's the reaction chamber and plumbing. But I'm a biologist and software engineer, so this kind of physical chemistry is not much in my training. I had a lot of fun in my chemistry classes, but I never went much past the required classes. I did think it was cool that we actually made a drug in my organic chem lab, but it was just sulphonamide.
