[Stoves] Summer Stove Camp 2015 Agenda

[Joshua Guinto]

Dear Crispin

>From the experience in selling stoves in the past years, i sensed that
every price bracket would cater to corresponding consumer sector as follows

Stoves sold greater than

                          1:  greater than $ 17.77 and beyond: business
persons
                          2 : between  $ 7.77 to 17.77  regularly employed
workers
                          3 : between  $ 7.77and 2.22 partly employed
workers, street food vendors
                          4:  below $ 2.22 marginal families

Consumers at Bracket 1 are well off families who would buy stoves with the
sculpted art works.

Those at Bracket 2 would buy stoves only as a back up for their gas or
electric stoves.

What i would like to cover are people in bracket 3. This is the market
sector where the consumption of wood charcoal is the highest and are always
finding means to save from fuel consumption.

Families at Bracket 4 would consume a combination of wood charcoal and raw
biomass fuel in very poorly designed stoves. They are less likely to buy
stoves and would rather make their own. This is the market sector whom i
would like to give the skills training and hopefully and consequently sell
it off to people in Bracket 3 and up.

For my latest stove model. (the PapaBrick Stove) sadly, the direct
production cost is at $ 11.21. of this cost, 68% is for labor.

The metal bucket has become a necessity for clients who would need
transport the stove all the way home This prevented breakage during
handling.  With my holey roket stove in the past years, about 25 % of them
broke during transport. The metal components represent 24 % of the total
cost. ($ 2.73)

It is very possible to sell it without the metal canister. The clients have
an option to buy the bricks as liners and install it on their own,  in
their own kitchen, pack it with clay or soft concrete. Cost of clay is
$0.77  and labor is $ 7.59 thus  total of $ 8.37. This will require a pool
of stove technicians who will assist and train the clients.

My workshop to produce these is very much artisanal. I started practically
with simple hand tools and learning from the techniques of local potters
and from the list serve. To achieve economies of scale and bring down the
cost down to $5 and less I need to fabricate/ purchase more efficient
machines including clay pulverizers, mixer, potter's wheel and a bigger
kiln, .... or have the stoves manufactured by well established pottery
shops.

On the brighter side, and from my own experience, this experience attests
that a poor family can actually make their own such stove with simple hand
tools. Which is why another client sector here in the Philippines are the
humanitarian NGOs for skills trainings. Some of the high points are the
families in the flood prones areas of Bulacan and then those at the
families ravaged by the Megastorm Haiyan. We connect the stoves to resolve
garbage problems,flooding as well as improve soil fertility to produce
food. Im happier developing the technology and teaching them to the
communities.


Kind regards to everyone
