Laurie & Steve,
Please go down the industrial area find the Adventisti office near
the Pepsi or is it the Coco cola distribution center on the road
bordering the airport on the town side.
We worked with trained the Adventist development Releif Organisaiton
(ADRA ) and three campos (Anta, Mossacyacta and San Louis, San Jose)
in the departamente de Cusco, in the art and craft of briquettemaking
between yr. 2000/2002. We also looked at the stoves in use tested
them and suggested alterations as partof that effort.
Alas, I have had zero feedback from that effort. It too may have
died on the vine(bad joke for a biomass user). It may have failed to
take hold, for all the reasons that you have mentioned and more
which take us away from anything technical and on into the fine– and
all too under-appreciated art of community development and
participative capacity development which underlies anybodys
development efdforts stoves briquettes solar tech methane or what
HArd one to figure out that....
At any rate, we discovered that about three times the wood was
required for cooking at that altittude than at say 0-1000 meter
(ie 4kg per person per day as opposed to the widely pubished figure
of 1.2kg per person per day).
We however, fairly well demonstrated that at the given produciton
scenarios (using a 4kw hammer mill the briquettes could be made in a
commercially viable manner even with shipping of the "BriquettasINTI"
into the cusco town center for sale.
I wanted also to add that some very recent and very positive results
are being gerated for side feeding of the hollow core non wood
biomass fuel briquettes through a modified Rocket stove, through the
good efforts of colleague Rok Oblak and Larry Winarski and others at
Aprovecho. Rok and Approvecho folks were at the Ethos Conference
and will be publishing their results soon. Our effort is not to
produce another be all fit all one solution stove butt to adapt the
principles of the findings to existing stoves---not for, but with,
and through the concerned end user. This latter part cannot be over
empasised if you want to make a good idea stick.
But please do get around to ADRA and find out wht happened to el
projecto de las Briquettas.
