All these concerns you have are trade secrets. I'm sure GE and Siemans would love to know what Harry has figured out. Please don't expect the Company to give up it's "secret recipe" to satisfy the concerns of shareholders.
Your best bet is to address the Company directly. Better yet, go and visit. Once Harry feels he can trust you he will talk your ear off. I promise he'll give you more info than you can handle. If you can keep up, all the better. He loves talking shop, engineering and steam. The more you know, the more he has to talk about!
I know this much: The engines run at supercritical, not "ultra".
Once the steam hits the pistons and "explodes", it begins to cool and condense immediately, it is further cooled as it is pumped back through the system to the heat exchanger where the process starts all over again.
So, far as I know the main pressure points are between the heat echanger and the piston head.
There were some experiments with different materials in some of the other moving parts. Ceramics, plastics and metals, but I don't know (or care) what was decided upon.
Hope that helps.
Just know this: This is Harry's life's work. His legacy. And he will get it right or die tryin'. I believe he is close, very close.
