I´m in Cambodia at this moment for the Global Allinace for indoor cook stoves,
I have been working with Dr. Larry Winiarski the inventor of the rocket
combustion chamber and the measures do not depend on any one opinion, depend on
what tipe of stove you want to make, the combustion chamber have to be designed
acording to size of the stove and the use you wanto make from this stove. I
tried many models but at the end Larry´s is allways rigth the the size of the
stove is very important for performance and it must be with appropriate
measures of the combustion chamber, pleas contac Larry for advise.

Richard did post a full reply to this enquiry, just not sure that it got posted
on to the people in question? Kind regards Adrian
