Thanks Anndy.

I did a bit of digging looking for anything on design of their system - assume it's a straight heat exchanger post turbine but hard to tell.

The business model is to sell an enclosed box to companies that only 1414D have a key to access and maintain - breakdowns at 2am will be hard to fix and commercial confidentiality/protection of IP will be difficult once installed.

In any case, 68% efficiency isn't near 90%, but I have a suspicion pressures were dialled down and operating conditions were suboptimal.
