Sometimes the cameraman zoomed in too tight and didn't show all fields. I don't think they were trying to hide anything. Since they were running the system in "manual" the engineer was probably keeping an eye on the slope of the reactor temperature, which they use as the control parameter. > According to the data presented by Alan, it appears that the input > flow rate should not have been materially modified by the reverse > steam pressure since that would not have been significant when > compared to the grid input pressure. I believe that typical (US) domestic water pressure is in the 50-80 psi = 3.5 - 5.5 bar range -- presumably gauge : add one, so it's 4.5 to 6.5 absolute, with maybe a back pressure of 1.5 to 2.0 max (absolute, not gauge). Of course, ancient Italian pipes might have a couple of millennia of Roman crud in them. > Has anyone seen the published data collected during the > demonstration? Nope : give us the dang data !!!
