[Stoves] ***SPAM*** Crude brick TLUD for developing countries

[Joshua Guinto]

DEar Kevin...

I sent you a long email in our previous conversation thread.

You may want to see my work for the past 10 years.

I have made brick TLUDs since 2010 and have created a lot of innovations
from thereon.It can run on wood sticks, shells, wood pellets, grasses and
leaves. and  briquettes.  From the simple stacks of bricks, I changed it to
become hexagonal so the fuel and fire chamber can be made cylindrical.  And
then from being batch fed, I revised it to run on continuous rocket mode.
And then from being fixed to a single spot, I designed them to be in a
transportable canister.

It works at best with pili (canarium ovatum) shells that we have abundant
in my region. One kilogram of pili shells gives an hour of clean flame, no
visible smoke and then about 250 grams of char.

The char can be harvested by pulling them out from the stove. The most
effective was to drop them to a pan of water.
