I got it wrong, too. Minute 5 is real-time 23:35. It is a shame they did not time-stamp the video. By the way, the graph on the last page shows the temperature rising after the cut off at 22:35. I assume these points are averaged and smoothed. The lines represent: blue Serie1 Ambient room temperature red Serie2 Inlet water temperature green Serie3 Outlet temperature Let's coordinate video and real-time: Video time 0:15 Gas is already added, pump is on. Resistor is at maximum power, 9 (as shown in video time 1:40). So this is after 19:40 real-time. Continuous video taken. Video time 3:42 Computer screen shows outlet vapor 129.10°C. Lewan says the test has continued for a couple of hours. He says: "We started at 6:30 pm and now it is is 10:20. (22:20)" Okay, that pegs the time. Transition at video time 4:13. Shows steam. Some water. Transition at video 4:40. Lewan says "Okay, now it is 10:30 (22:30)" Heating is shown at full power, 9, continuous duty cycle. Video time 4:50. Power is turned down to 0. Lewan: "Now at 10:30 we switch off the electrical resistance." Amperage drops from 11 to to 0.1 A. Continuous video. Video time 5:50, one minute after power cut off. Computer screen shown. No change in outlet temperature, which is 133.50°C, computer time 22:38. So, cooling is not instantaneous; the power supply did not affect the thermocouples. The log shows the temperature is 123.0°C. This is probably a typo. Will ask Lewan. Video time 6:04. Video transition. Lewan: "Now it is 10:10." (He must mean 11:10 pm; i.e. 23:10) "We have been going a half an hour without any electrical energy." (Actually, 35 minutes.) Video 6:45 valve open. Hot water and steam come out. Video 8:07. End.
