[Stoves] TLUD before 1985 needs documentation

[Crispin Pemberton-Pigott]

Dear Jeff

I didn't really discover anything! MCC brought them to my attention asking
for an emissions and performance test. They ran their stove their way, I ran
it mine the next day. It has potential and how to achieve it was conveyed to
them in a way they can improve it immediately. It may need a little
refinement for a month or two.

I am bit bemused about the fuss over who invented what. The Romans used TLUD
fires to limit smoke production. Nat and I were discussing it in Washington.
Some things are just worth rediscovering.

Let's get on with more and better stove designs. I met someone in DC who has
a new idea for basic can type stoves that I have not seen before. He has
been doing experiments and has successfully shortened the flames. That will
be of interest to Indian stove makers because they have height issues.  I
will get back to you on that.

Regards
Crispin
