[Stoves] RE: Urban Poor

[Kobus]

Reginald,

Contact me off-list on ventfory at iafrica.com . There are two other stoves (as
far as I know) being promoted in the RSA that are using Ethanol gel.  Reply
to my email address listed above and I'll give you more information or if
you want access to cheaper Ethanol gel. 

Regards

Kobus

 Hi Allbody,

I just joined your mailing list as I have an interest in stoves for the poor
in developing countries (mainly Southern Africa).

Currently in South Africa (RSA) the most common (not popular) stove and fuel
is the Paraffin stove (US$10) with paraffin retailing at (US$.70 per litre ~
US$60 per month). The only problem Is that the stoves are not stable and
usually tip over and burn down a whole community of shacks. Unlike most
urban poor, here in South africa people wuold also like a stove they can be
proud of!

For RSA the requirements are

Safe (stable and no harmful emissions)
Cheap fuel
Efficient (fast to boil)
Long lasting

In this order!


I am currently trying to introduce a stove using gel fuel because a gel has
a lower flow rate to a liquid. However, as the gel fuel is derived from
ethanol there were concerns that it will produce acetyldehyde fumes or even
acrolein and is more expensive than paraffin (USD1.4 per liter)? Does
anybody know of a way to produce the gel fuel cheaply? There are also chaps
working on a paraffin stove that switches off if it falls over.

My aim is to develop some self shutting device that will cut off the air in
the gel stoves as the gel stops burning if there is no air. Does anybody
know of any stove valves that shut off on heavy contact?

I hope I have not derialed your discussion!
