>Most people don’t measure “black-boxes”. Correction: Most people don’t measure “black-boxes” with instrumentation by the invetor, placed by the inventor.

Rossi used steam for heat removing in January,March,etc and you know that steam carry out very little heat compared with liquid water. You cannot claim on “Safety” for this. And in Oct 6 water was not used in the reactor, but steam. If only steam was OK for heat removing in Jan, March, etc, steam + secondary was at least equal, independently of how much water was flowing throught secondary. >Most people I know who do a lot of calorimetry prefer a smaller Delta T, >between 5 and 10°C.

If Rossi provided a 30-40 degrees difference, everybody can feel it simply touching water in exit. With 4-5 degrees not. Again, Rossi missed a very simple step, suggested many many times from a lot of people.

Why not reduce the water flux and get 30-40 degrees Celsiusof difference instead of 4-5 degrees? Two reasons, I think: 1. Safety. You want to be sure the heat will be removed even if it increases a great deal, the way it did on Feb. 10. 2. Most people I know who do a lot of calorimetry prefer a smaller Delta T, between 5 and 10°C. They prefer to keep the absolute high temperature below ~30°C. Above that you get problems with the fluid characteristics changing, and the conversion rate of 4.12 J = 1 cal. starts to change a little. There is no difficulty measuring a difference of 5 and 10°C. There is no chance of a mistake. With modern instruments you can measure a difference 100 times smaller (0.1°C) with absolute confidence. The signal-to-noise ratio is not enhanced much by going to a 30°C difference. - Jed
