[Stoves] ETHOS Discussion about decentalized stove efforts

[Crispin Pemberton-Pigott]

Dear Dieter

 

This is an excellent point:

>One of many reasons for “coupling solar and wood” is that there are
additional applications for comfortable use of the solar cooker: baking,
bottling, preparing juice or jam and other products which cannot be prepared
with stoves which work on high temperatures. The SK14 and similar solar
cookers do not surpass 200 °C.

There are so many sectors of the stove market that we should prepare
appliances for and it is good to be reminded now and then that the local use
to which a stove might be put could be very much unlike ‘cooking’.

In Indonesia people routinely have 4 or 5 different cooking devices which
they use when they are preparing ‘that food’, just like I do at home. Each
one can be called a stove, but they are specialised, really, and do
something things really well that he others do not.

Cecil Cook in his investigations last year into the use of fuels and stove
found people in Central Java (where is about to be launched an improved
stove rollout) were very adept at picking particular fuels for certain
purposes, as well as using multiple stoves during any month. Come fuels were
used only for high power and some for keeping a fire just going for a long
time. 

The use or solar cookers for processing during the daytime (work time) is
logical. It has proven quite difficult to get people to move mealtimes from
late in the day (to suit solar better) but that doesn’t mean there are not
applications for it.

I recall the SK14 well. I entered a cooking competition using and SK14 and
it definitely exceeded 200 C (cast iron 3-legged pot) when cooking with a
small amount of oil.

Regards

Crispin
