I use stainless steel rods 8mm with gaps of 8mm. This allows the pilinut
shells to fall off after it has fully carbonized. Will adopt the idea of
the tilted grate 20 degrees.
Also Im struggling with TEGs. Its an amazing project and still cannot get
it started. I suppose it would be very easy to simply embedd the TEGs into
the clay wall and poke the wiring out to a fan or a charger. Could you
please tell me more. about this..
News on the side.... im contemplating about joining a humanitarian mission
next week. There are close to 3,000 refugees that fled from a conflict
zone. The place is Tandag in the province of Surigao del Sur. Their tribal
leaders and their teacher were executed by a paramilitary group who was
organized by the Philippine Army.. the evacuees are in a sports complex.
My friends are going for a feeding mission. am raising some funds for my
plane fare. also thinking about bringing my stove and have it tested
there... .. to cook, to make bio char.. to use the biochar for sanitation..
to make compost,.... to teach people on approtech....
