Twice the output of the primary was measured. You won't see it in the spreadsheets(because it was only measured twice). Look in the .pdf file from NyTeknik: At 18:57, the output of the primary of the heat exchanger was supposedly 23.8 degrees. Less than room temp, less than the input OR output of the secondary. So, this transfers heat between primary and secondary well enough to surpass even the lowest temperature of the secondary? At 19:22, the same thing, but only 23.2 degrees.
I built the same charts as everyone else last night, and while looking hard at these numbers, the calorimetry doesn't add up. The measurements at the secondary don't seem to actually track the E-Cat in any meaningful way, and are too infrequent to track changes. A quick example is between 19:03 and 19:22: In that time frame, E-Cat temp is steadily decreasing, hydrogen is purged, and water flow increased (in the primary), but in those 20 minutes, the output supposedly increases from 3.9 kW to 6.1 kW. None of this adds up, which is why I was questioning how they measured the output of the primary. Either that thermometer is wrong (and I'm wondering where else it was used), or all of the others are.
