[Stoves] Going back to 3-Stone Fire [Was Re: Chinaandcookstoves]

[Kirk H.]

Xavier,

I am surprised to read that you don’t know whether you disagree with the sensors, computer graphs, and filters along with the water boiling portion of the test.  I did not specify Aprovecho’s equipment in my question.  I tested the same stove on both Aprovecho’s and Lawrence Berkley National Lab’s equipment, and the tests both showed a very clean stove.  Does the disagreement include Lawrence Berkley National Lab’s sensors, computer graphs, and filters along with the boiling water portion of the test?  What exactly do those who disagree with the WBT, disagree with, just the water boiling portion of the test or the overall test?  Is the Controlled Cooking portion of the test also included in this disagreement?

Dear Kirk,

“Do you disagree with the sensors, computer graphs, and filters along with the boiling water?“
I don’t really know about that. I believe Crispin said the measurements from Aprovecho equipment was unreliable.
Other than that, the PEMS was breaking down all the time at Prakti, and I believe there are other cases where it happened.

Best,

Xavier

I have a question.

When I test a stove I see sensors, computer graphs and filters along with the pot of water.  Do you disagree with the sensors, computer graphs, and filters along with the boiling water?  The water boiling portion of the overall test appears to attract your attention.  How much of the overall test do you disagree with?  What do you mean when you disagree with the WBT, are you including the sensors, computer graphs and filters?
