That's confusing, isn't it? The Jan. 14 test was about an hour. Not sure how long it took to reach the terminal temperature and dry steam, but after that they ran for 30 minutes exactly. I have a graph showing that. It shows the reaction quenching remarkably quickly. That's almost as good as starting up quickly. It would be nice to have a cold fusion reaction we can turn off. 30 seconds is how they quote the flow rate. It seems the pump setting is for 30 second intervals; i.e. 146 ml/30 s. In the video the pump makes a loud noise and sends a pulse of water every few seconds. I can understand just enough Italian that I think someone is saying "that's the pump." A constant displacement pump grabs a precisely calibrated amount of water and sends it in a pulse, so you vary the flow by timing the pulses. Peristaltic pumps have a more even flow. Peristaltic pumps are an example of technology that by rights should not work, but they managed to pull it off. They overcame what seemed to be insurmountable problems with plastics. You have a wheel pressing down and squeezing the plastic tube thousands of times an hour for weeks or months. Early plastics quickly became brittle and broke. I don't recall who did this, but I read about it and I got the impression that person really, really, REALLY wanted to make peristaltic pumps work, driven by some inscrutable inner desire. - Jed
