Jack - Well that is interesting. It may be a relic of too little data which will average out over time, but it may also mean something now.
IOW, it begs for more confirming data with slight changes that would accentuate the effect by adding increasing levels of H loading with every run. Since you have some data that indicates an effect, if another set of runs confirms this at a higher level based on the prediction of an effect due to increased hydrogen loading - then it becomes more meaningful. Why not go back and do several more sets of identical runs like those - with the only change being that you have electro-etched the exposed electrodes for units of increasing duration. If that chart then shows a trend towards greater and greater delta-T (both up and down) with increasing loading - then. voila, you have something which could be important. From: Jack Cole Jones, I went back and looked at some of my previous results, and they do raise the possibility of anomalous cooling. I was a little confused by these results at the time. After our discussion, I think this is exactly what you were predicting. The control trial used HFAC pulses through a beverage heating element (2 seconds) alternating with 30VDC electrolysis through the nitinol wire (10 seconds). The experimental run used 30VDC electrolysis for 10 seconds alternating with 2 second HFAC pulses through the nitinol. Notice that the beverage heater temperature produced results above the predicted amount and nitinol pulses produced results below the predicted amount. I don't make a whole lot of the beverage heater being above the predictions because I don't think there would have been a lot of hydrogen loading into that. But the nitinol results are intriguing enough to explore further. Here is the chart. http://www.lenr-coldfusion.com/wp-content/uploads/2013/01/EXP52.png Best regards, Jack On Wed, Jan 23, 2013 at 9:19 PM, Jones Beene <jone...@pacbell.net> wrote: A combination of vinegar and hydrogen peroxide works with nickel-copper and is very safe. This is often used to etch PCBs. Using a few volts with the wire as cathode should also load H2. The muriatic may work better on Nitinol. This is not precise calorimetry - Terry. you can to call it "thermometry" and be sure to stir. Just a simple way to gauge the comparative ability to raise the temp of a known mass of water. Using the specific heat to arrive at joules and logging the P-in, you can get a ballpark but the basic idea is comparative between a wire that may be slightly gainful and one that may be slightly endothermic. The idea is to see if there is anything "obvious" there, before incurring the expense and time of doing it right. For instance, going from 25C to 75C in an hour with Constantan at (x)watts P-in vs. 25 C to 65 C with Nitinol (both wires of the same Ohmic resistance) and everything else being the same . that would be interesting enough to dig deeper, no? Ahern's finding of anomalous endotherm with nickel-titanium is 'out there' in the public record and ought to be corroborated or debunked. From: Jack Cole I could run some low power electrolysis for a day or two in some diluted hydrochloric acid. Think that would do the trick? Or do you have another idea for the acid? Hydrogen loading will surely be necessary at some level, but can possibly be accommodated by combination of low pH electrolyte, not so low as to dissolve the wires. or preferably by preloading etched wires for a day under H2 pressure and modest heat, or even the simplest expedient which would be during a slow electro-etching in weak acid- with the wires as cathodes. The last would be the easiest to try for anyone without H2.
