The best way to identify the cooking needs of poor people is to ask them after
spending considerable time with them in the field to understand their situation
(ie to understand the cooking problem intimately and then brainstorm solutions
together)
This supposition that we have to cook indoors in much of the developing world
is something that should be debated widely. In the western world we don't warm
up our cars for extended periods in our house as we all agree this is poor for
our health. Can we all recognize that it is a much better idea to run
combustion appliances for cooking in an outdoor environment(especially in the
tropics).
The poor affordability and replicability of "high tech" stoves and fuels is a
serious development barrier. Cooking outdoors (especially in rural areas) with
appropriate local and low cost improved stoves and fuels is the most
sustainable approach to address the health impacts of cooking. We need to
combine improved cookstoves with a cooking environment that does not have
stagnant air (ie one that recycles particulates or doesn't allow for particle
dispersion). Cooking outdoors in rural areas has no ambient air impacts on
communities so let's just do it. We are promoting this concept in west africa
with the REAP clay brick stove known locally as the Noflay or "no problem"
stove in the region.
The health impact is a function of the technology x cooking time x environment
in which the cooking is performed.
We can express it in an equation form as H=T (technology) xT (time of exposure)
x E(environment) in which the cooking is performed.
All the best

Rogerio etal
Brazil is going to be leading the way on biofuels of all types. In addition
to ethanol (from sugar cane?), there are numerous plant species producing oily
seeds that can be pressed. From time to time we have had seed oil proponents
on this list. We have had several for ethanol stoves
I had in mind also the use of all sorts of liquid fuels that can be produced
from pyrolysis - with a biochar co-product, so we can accomplish some CDR
(carbon dioxide removal).
Liquid fuels can burn very cleanly and are nicely controllable.
