[Stoves] History of clean Chinese stove development. Re: Rights about stove designs Re: [biochar-stoves]

Dean and all,                           (To post at www.drtlud.com , but 
all replies via the Listservs, please.)

It is remarkable how the documentation of the development of 
clean-burning stoves in China is so scarce.   If you can influence 
anyone to actually substantiate what you have written in your email 
below and put it into English, that would be a great service.

Instead, the evidence that comes from China today is that the air 
pollution from the coal burning stoves is horrible and that they are 
wanting solutions.   And I doubt that the principles of TLUD-type 
combustion are being used with those hundreds of millions of stoves that 
you mention.

Crispin reports great success of lower emissions with gasifier-type 
(whether TLUD or not is not an issue) stoves (for cooking and for 
heating) burning low-grade coal  in Mongolia.  That is documented 
evidence, and the concepts and designs did not come from copying the 
Chinese coal burning stoves.

Less than 10 years ago (2007) there was a competition of clean 
cookstoves in China.  Dana Charron and Berkeley folks helped run it.   
Many candidates.  Of the seven or eight finalists, only one (Daxu) was a 
legitimate TLUD gasifier, and it won first place.   So, I see no support 
for your statement:
> the modern Chinese stove community has specialized in TLUD type 
> natural draft stoves for more than 20 years.
Dean, you and anyone else are invited to present documentation about 
stove progress in China or in any country.   But simple statements 
without backup documentation are not sufficient, and should not be 
coming from a person who is continually invited to represent the 
informal Stover Community to administrators and sources of funding.   
Your comments below only contribute to the myths that plague our work 
and our progress.
