[Stoves] Fuels of the future

[Joshua Guinto]

Dear Crispin, Paul and everyone

Let me jump into the conversation.

I am now in the midst of the gasifier stove i am fabricating and the
abundant supply of pili shells. Pili *(canarium ovatum)* is an endemic
species of my place here at the Bicol Region which is south of Manila. The
shells  are very much heavier than macadamia nuts and has a density of 0.87
grams/cm3. .

Two days ago we began hauling 4 tons of the shells to become my stocks of
fuel. I will sell the shells along with my PapaBrick Stove. And then, while
we are hauling the shells, we were offered another 6 tons of shells from
the neighbor farm, both in the same village. I used to purchase the shells
from another village where to my best estimate, there is more than 10 tons
per month that are very much underused. This supply is expected to increase
as more farms have planted thousands of pili trees as the farmers got more
awareness with the use of the shell for gasifier stoves.

On the other hand, the PapaBrick Stove is giving us satisfying performance,
now that we know better how to use it. It  can perform as a TLUD gasifier
stove during the cold start phase and then work as a rocket during the hot
start phase in a continuous mode.

One load receives 1.25 kg of the shells and runs for 75 minutes of very
clean flame, boils 4 liter of water in 14 minutes during the cold start
phase and then 9 minutes during the hot start phase.

After the flame has gone out, we can harvest an average of 2.73 grams of
char from the raw fuel of 1.25 kg or about 21 % recovery.

Going further i fabricated a lantern on top of the stove. And it was very
satisfying.


Regards

JEd
