Not sure how that helps if it melts through the floor, the truck, and then the ground when you turn it on. Those are nice improvements, but adding a red paint job to a wingless plane won't make it fly.
Suppose you could use some kind of ablative material, but that would mean short runtimes and constant expensive refits. Sort of like taking that wingless plane and launching it with a trebuchet. Technically makes it fly but not in any way that matters.
Hmm so if I understand this right, the idea is to coat the reactor in salt with progressively lower melting points? And I suppose each layer is supposed to extract some specific element.
I'm still not seeing how this prevents corrosion of the system, but I suspect their actual intention is to just run it in short bursts for material production which may be workable to some extent. A transmutation reactor of sorts?
Maybe we should just build them in orbit without containment and let the surface tension hold it together or something.
