Dr. Karve,
Being neither a physicist nor a biologist, I can only hope that what I
have read on the matter is at least fairly accurate. What is claimed by
the various patents I reviewed is that the use of a porous refractory
material that radiates IR in the appropriate range when heated, either
directly by combustion in/on it or by passing hot gases through it, can
redirect heat that would otherwise be lost up the flue.
One might assume that if ceramic radiant camp stoves are more efficient
than an open flame then a radiant TLUD or Rocket stove might also be more
efficient. The result of the discussion on this thread up to this point
would seem to be a definite maybe.
I hope that more than a few from this list might also attempt some bold
experimentation, as Paul Olivier has done with his found strainer (only
the latest in a string of inquiry and innovation). I will be playing with
some screen and with John Davies' ideas, as soon as I rebuild my little
Lion Cub stove for the season. Still a few snow storms to go.
