Great progress in Philippines

We’re happy to publish roket stoves by Joshua Guinto from Philippines!

Amazing different designs from Joshua – here in the shape of a fish, truck and a human face!

Here are some interesting words from Joshua:

It is a mixture of clay that i have in stock. I mixed 3 parts of dry and sifted clay with 2 part of dry coco peat (coconut dust) and 1.5 parts water. I had them mixed in my pendulum mixer and packed them in two PVC pipes as molds.

Here in my place, we have so much green coconut shells at the market place as waste. They are dumped on open lots and is contributing to the risk of dengue infestation as they collect stagnant water for the pregnant mosquitoes. I think, it will be nice to have them shredded, mixed with paper pulp or starch and formed into briquettes.

Another plan is to revive my solar dryer for drying the briquettes. Here in the Philippines, there are intermittent rains in a single day so that will also be necessary. I have made several models of them before… and now there are new reasons to build the dryer again.
