Homemade portable stove based in the old petrol-powered camping stoves, wich have a feeding system with a separated reservoir. I made this one alcohol powered because of soot reasons. It's not perfect like de Tetkoba's ones, but it's efficient and functional.
This is made out basically from garbage - soda and deodorant cans, a tube from a folding clothesline and pieces of scrap steel.
It's the evolution of my "super successful" alcohol burner.
