I thought of three ways to do this the moment I saw the video: 1. Put a tap in the hose to draw off samples periodically. To get an accurate temperature, you draw off 1 L into a Dewar (a thermos bottle), stir vigorously and insert several thermocouples and thermometers. 2. Use a 1 m hose from the heat exchanger into a large bucket. Place a utility pump and garden hose in the bucket to pump the water outside. 3. A variation on #2, drill a hole in side of the large bucket close to the bottom, glue in or screw in a pipe fitting, and attach the 20 m hose. Methods 2 and 3 are preferred because they would shorten the hose and prevent anyone from accidentally stepping on the hose or kinking it, which would change the flow rate. You will note in the video there was a doormat sitting on top of the hose. Yes, a DOORMAT, for goodness sake! What kind of idiot puts a doormat on top of hose in an experiment in which a stable, known flow rate is critical?!? Of course the flow rate should be recorded on computer anyway, but still, that is an extraordinarily lame brained thing to do. If Rossi had allowed me to look at the setup a day or two before the test I could have made this along with the other changes I suggested. That is purely hypothetical; e would never allow me or anyone else to make any changes whatever. I expect he would not even allow me or anyone else to zero out the meter or install an SD card. I should point out that these suggestions I made were not only from me, they were from distinguished experts. I told him so. It isn't as if he is rejecting only my suggestions. I do not take it personally. As it happens, I offered to visit him with a team of experts from the second best technical university in the U.S. to evaluate teh setup and take data. He refused, rather ungraciously. He told me, in effect, that under no circumstances will he ever accept any suggestions from me or from anyone else. No matter how qualified you are, you will find there is no point to making technical suggestions to Andrea Rossi. It is a lot like talking to a wall. - Jed
