- Tom Droege comments: "The Takahashi configuration is such that I don't know
- how to get a model, and thus don't believe that it can be calibrated."
-
- We don't need a model to calibrate. We run a heater, then we run electrolysis
- at different levels, and we get straight calibration lines. During the
- experiment we watch the input power, the flow Delta-T, and the box
- temperature; they track very closely. This proves that box temperature
- measures heat accurately.
-
- We know, beyond any reasonable doubt, that the water is constantly, thoroughly
- mixed. This is a clear plastic box; you can look inside it, and see that the
- water is bubbling, sloshing and splashing around. Bubbles, and occasional
- small pieces of grit, are driven everywhere. Furthermore, we have three
- thermocouples, separated vertically and horizontally. With joule heating, they
- show a thermal gradient. With even one watt of electrolysis, the gradient
- almost disappears.
-
- We don't have to know exactly how the box works in order to be certain that it
- *does* work. A computer model is good, but actual experimental data is
- indisputable proof.
-
- Before I leave for vacation, I would like to quickly address your other
- statement: "We live in a fluid called air, Jed. Sometimes we have Tornadoes,
- but not all the time. They are very capricious. That is because temperature
- gradients in a fluid can do very complicated things..."
-
- "Capricious" is the key word. Storms do not start up after a few weeks, and
- persist for 4 months steadily. They do not respond to input proportionally,
- changing in a precise manner every 6 hours. They are not inversely correlated
- with neutrons.
-
- Takahashi's grad students hauled the box out of the neutron counter by pulling
- the red wires shown in the photo, and sloshed in new heavy water periodically.
- Flow gradients would never survive such jostling; they would stop temporarily,
- and then take another two weeks to restart. The conditions in the box were
- just as conducive to thermal gradients during the first week as they were 2
- weeks later, or 4 months later. If this miniature storm could flick on at
- random after a few weeks, then sometime during the next four months, it would
- flick off again at least once.
-
- Furthermore, if a gradient could produce a bogus 30 watt positive reading on
- the low end and 100 watts on the high end, then from time to time it would
- produce strongly negative readings of -30 and -100 watts, as the flow shifts
- capriciously around. Neither Takahashi nor I have ever observed anything like
- this. In any case, visual observation of the box and my computer data both
- prove that there are no gradients, and that Takahashi was not seeing a tempest
- in a test tube.
