They have been talking about ceramic car engines for decades. Could the tech be scaled down?
We need to read up more on it but I do believe it can be scaled up or down.
The jet engine parts I think they are talking about is the very core that of the jet engine where the jet engine spines or fins are attached to, or dove tailed into.
The problem with ceramics in the past is that they were brittle, or can crack, but now this new material is a big game changer because it’s properties act like ceramics that can handle extream tempetures, but yet are as strong and durible as metals, and light weight.
I don’t think it’s a scaling problem, but a mass production problem.
Vapor deposition happens in a vacuum chamber under high thermal conducting conditions; not suitable to bulk material economics.
But if he keeps going, then yes, an internal combustion engine (ICE) made from 100% of this stuff could run incredibly efficiently.
I would suspect an ICE made this way now would cost $100,000 or more. But when compared to a $26,000,000+ jet engine, it’s a small portion of the total cost (Burners and first two turbine stages).
