I think is not so new, Dr. and Ing. Larry Winiarski have develope many desings
like this but no very many people put atentiona to his work.
I´m sorry for my coments but that the way it is.
Any way any effort to improve cooking is great in any place in the world.

Subject: Re: [Stoves] Introducing a new low cost clay brick stove
Dear Stovers,
We have been working in West Africa to find a new way forward to develop
affordable stoves that are cleaner burning and save more fuelwood. At the ETHOS
conference, Rebecca Chin and I will give a presentation on the new clay brick
stove REAP developed in 2012 and our efforts to install 2000 of the new stoves
last year.
Since 2005 we have been working in West Africa to introduce the Mayon Turbo
and metal rocket stoves in rural communities. Our main problems have been that
these stoves were undersized for the large cooking pots, are much too expensive
(as Cecil poignantly highlighted) and, in the case of the metal bucket rocket
the stove was short-lived.
So we went back to the drawing board to develop a low-cost clay brick stove
with custom-made bricks to deal with the large pots. Over the past year, with
funding from the Canadian Government, we have come up with the Noflay stove or
“no problem” stove. The stove is essentially made up of two components: a
central combustion chamber of fired bricks and a shroud (a mortared brick wall
custom-built to the pot size). In brief, the stove has many of the design
features of other large improved clay brick and metal stoves (i.e. low excess
air, preheated primary air, secondary air, good heat transfer) but is much less
expensive. The total installed cost of the stove is about $10USD and it can
hold a 34 cm pot typically used for a household of 12 or more. Compared to
other advanced clay brick stoves some key reasons for the low cost of the
Noflay is its resource efficiency because of the round shape (i.e. use of
custom made bricks in both the firebox and
shroud), the limited use of kiln fired bricks and its focus on locally made
bricks which reduces transport costs and brick breakage.
Please find attached some of the photos of the stove being constructed.
