I'll maybe believe it when I learn more. That it's an idea on paper only means it's way too early to tell. I'm also wondering if they are relying on exotic building materials being developed in the future for this to work, like a previous expensive but failed US space-plane program.

The critical part (the cooling mechanism) has been fabricated, and validated in tests.
