For everyone watching. On the Gamma pump thread I have been challenging the overall conclusion that Alan Flecher mentions here. On the evidence so far the Gammas seem capable of delivering only about 2/3 of the output Penon claims.
I mildly disagree with Bruce.
I do my comparison based on 4 Big Frankies in operation, 1MW nominal power. For some days Penon reports that one BF was down, so the pump volume was reduced, and the output was only 3/4 MW.
There may be meta evidence (which never got to court) that one BF was down when Penon reported it was up, but that's a whole different ball of wax.
