We tried making the centrepiece from clay with some success on our older
model though we never introduced it into communities. It doesn't have
the same stability as the ring structure for holding pots. A clay
centrepiece would reduce the stove cost by about 1/3rd compared to a
metal centrepiece. If we went with the small Mayon Turbo 6000 model and
a clay centrepiece we might be able to get the cost to $4-$4.50 per
cooker. Next week I go to the Philippines and we plan to do a bit more
development work on it while I am there. Likely it would be a good
option for us to reduce our risks on loan repayments. Once people could
afford it they could upgrade to a metal centrepiece if they so desired.
It would be interesting if someone (like Dean Still) who has more
experience than us with other materials used for stove fabrication could
also try experimenting with insulative materials and incorporating them
into the stove design.

Hi ron
Yes we have tried making the centrepiece from clay with some success. On
my trip to the Philippines next week I plan to test it
