Shell Fdn proposal

["Jon & Carrol Otto" <otto@sover.net>]

Paul, et. al. --

Paul's point about not sharing as much during this Shell RFP period rings
true. As a mainly silent, lurking type of stover anyway, my non-contribution
in recent weeks was hardly noticed.

Still, I will glaldy tell anyone interested that we put in a concept paper
to Shell under our program called ProTREE (Promotion of Technology for
Renewable Energy Enterprises). The funds requested were to further our work
with plant oil (Jatropha curcas) fuel and appliances in Tanzania under the
Health and Household Energy component of the Shell RFP.

We now have a functional prototype stove using Jatropha oil -- a fuel which
seems totally renewable and clean-burining (no emissions testing to support
this latter claim). So the idea is to further develop the energy system
around this liquid fuel -- the energy farms of Jatropha plantings on eroded
or otherwise underused lands that supplement and eventually replace some of
the unsustainable harvesting of woody biomass, and the production/marketing
chain to bring the fuel, cookstove, lamps and manual oilseed press (for oil
extraction) into commercial use.

OK: that's our humble story. Anyone else wanna step forward about your Shell
gambit, and let the 'funding chips' fall where they may?

Subject: Stove efficiency

>Someone on the Stoves list previously stated that the energy output from a

>(assuming the same fuel).

>and
>
>C).  Cultural (not physical) issues of SOCIAL behavior (cooking practices)
>and ECONOMIC realities (cost of the fuels) that may make the above two (A
>and B) of less consequence.  Examples:
>1.  Rural primitive cooker (on 3 stones) in a forest with few other people
>and such an abundance of wood available that the thought of saving wood
>would be beyond imagination.
>2.  Oven cooking vs "burner-top" cooking in pots vs "food-over-flame"
>cooking (as in meat over an open flame).

>Stated another way, do we or anybody have functional measurements of
>efficiency (other than how much water is boiled in X time by Y amount of
>fuel Z)??   And is that even important?   I believe that it is important,
>but how much effort should we expend on defining and operationalizing some
