How would you have done the test without $100,000 instruments? Bob never affirmed that his experiments were scientific. It was an "ad hoc" experiment. Well done experiments, whether executed with costly or cheaper apparatus, fully documented with the results, can be useful. Look at them, study them, and draw your own conclusions.

I don't want to get into a huge debate with you about the heat/acid test where Bob used test tubes and a propane torch. I have already posted my concerns about this test and Bob actually agreed that it may have been flawed due to the reasons that I pointed out on the old board. Just in case you can't find my old posts about it some of my concerns were
1.Inconsistant heating between samples.
2.Inconsistant stir rates.
3. Test tubes were at different points in the flame.
All of the above leads to inconsistant heat rates and inconclusive results at best that should not be posted here. They only serve to confuse others.
You for one, based on your bio and all of the very technical threads posted here should be in agreement with my opinion. I am very surprised that you have taken the stance that you have.
As far as your statement on needing a $100K instrument for Bobs test, get real! I am not stating that what Bob was trying to do was bogus, what I am saying is that he could have done it better by heating them all up at one time as they were partially immersed in 1 qt of high temp oil. Then I believe that the data, while not 100% scientific, would be more conclusive because it was done consistantly between all samples.
I think I could reproduce his test for well under $100.
Lastly, I want to be clear about one thing! I have the utmost respect for Bob!!! He was and is the main reason why I participate on this forum. I believe that he, like you, are very knowledgable individuals that have a lot to offer.
I just wish that some of his backyard tests were more well thought out. I see your name alot here, so you know that I am not the only one with problems with some of the tests being performed. That is why we have the oil analysis sections to deal with oil issues that have their merits based in science and accurate and meaningful testing methods.
