- I blush when I read Dieter Britz's comments about clean. OK, I am slowly
- learning. The brass came from a gold plated connecter in the gas at the top
- of the cell. At high currents the cell must be full of churning hot vapor.
- At least it ate the gold and then the brass. That design was at least a year
- old. We do better now.
-
- Mitchell Swartz asked about the stainless steel. It was likely #304W, but it
- could have been #316. There is still a piece of stainless steel in the
- present cell. Also glass, teflon, Pd and Pd.
-
- Forgot Polypropylene and the catalyst which is proprietary Pd compound on
- an alumina substrate. The next generation cell will be Teflon, Pd, and Pd.
- With the catalyst in a second compartment. Still if bad stuff leaches out
- of the catalyst, I will be in trouble. This is an argument for using the
- hot Pt wire technique as used by Scott. Or better still, hot Pd wire.
- Once it gets going the current through the wire can be turned off. My fancy
- electronic system allows me to do such things while maintaining a balance.
-
- I know my hardware store bought solvents and clean technique look awful to
- you Dieter. I learn every day, and hope to get up to a C or so in clean from
- my present D- or E.
-
- I note that most of the experiments I have seen (with the exception of McKubre)
- are just as bad from an electronic measurement standpoint as my level of clean.
- Two clip leads indeed!
-
- This is an argument for getting us together. I will be able to take the next
- generation calorimeter apart, put it in my car, and take it somewhere where
- an electrochemist with a clean lab can put something nice into it. Sorry
- Dieter, I cannot drive to Denmark. But I am open to nearby offers.
-
- Since no one in the US wants to pay to put together a good team (except EPRI
- and they are after commercial interests) then we have to piece it together
- as well as we can. So I tell all on the net and you beat me up. With each
- blow I get stronger.
-
- Since I follow the semiconductor industry I can reveal to you all that often
- the only difference between a 10 cent transistor and a $10 dollar transistor
- is that the $10 unit has been tested. Are there solvents that I can use that
- are naturally clean by the way that they are made? Where ultrapure means they
- have taken standard production stuff and measured and certified a purity level?
-
- I think the difference that Jed Rothwell has with many of us is that he choosed
- to believe the measurements that he has heard about. Some of us have to see
- enough detail of the measurements to make them credible to us. Most of the
- positive results that Jed relies on are not yet in Dieter Britz's bibliography.
- To a large extent, I agree with Dieter not reading work that has not been
- reviewed and published in a journal. I am particularly upset with McKubre. He
- has had plenty of time, and his work is good enough for publication. So Mike,
- put your reputation on the line and submit a paper! Or shut up and go
- completely secret!
