"All these concerns you have are trade secrets. I'm sure GE and Siemans would love to know what Harry has figured out."
My point was that GE, Seimens, et al have been quite willing to discuss the use of high tech stainless steels and the upper limits of those materials.
USC steam is indeed an issue. Like I said, Google it. If it's a problem for Seimens & GE it's a problem for Harry. The laws of physics dont change from invention to invention.
What is weird is the fact that Harry has said nothing at all about the same issues he has to be facing if indeed he's operating in the 1100/1200 F temps and 3500 PSI.
Something as simple as 'we've partnered with Sumitomo Steel etc... and used their proprietary stainless alloy which survives the 1200 F temps the steam is heated to.' most definitely would suffice.
Silence instead....
"Please don't expect the Company to give up it's "secret recipe" to satisfy the concerns of shareholders."
I don't but there isn't even one line on the company website about the need for very advanced metalurgy, which to me sets off alarm bells, especially after reading up on the subject of USC operation.
"Your best bet is to address the Company directly."
Talked to Frankie already. One of the polymers she's divulged has an upper limit 500 deg F below purported operatring temperature of 1200 deg F. How is it surviving under such conditions?
"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."
The temperatures and pressures claimed by Cyclone are indeed ultrasupercritical, as far as all the papers I've found on the 'net. Cyclone's website claims 1200 deg F, and 3200 psi
Southwest Electric Power co defines USC steam: In general, an ultra-supercritical (USC) steam generation unit represents an advancement in conventional coal-fired steam generation. It involves the use of supercritical steam pressure and the use of steam temperatures at or above 1100 degrees Fahrenheit (593° C).
"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."
I'd agree about the heat exchanger and head of course, and say again, they need to be made of some pretty special steels to survive any length of time at all.
It would be good for investors to see one engine running at total loss at USC temps/pressure. There'd be so much steam in the air the engine and building would be invisible.
