I'm glad to be out of the technical analysis here! I have found the rumoured 100.1C fascinating. But, unless the ERV report includes proper pressure measurement, there can be no power assured beyond 70kW or so - and that would depend on many other unknowns being correct. So very many unknowns it would not possible to comment (were I commenting) except to say that the claimed 1MW is impossible to measure with safety. I said that before, so it is not a new comment.
I will be fascinated to find out what the setup really was...
