I can't give you scientific numbers on efficiency of a gasifier vs typical burning of wood, but.......

A gasifier makes use of more or less ALL the available chemical heat. Once it's going, the voltatile gasses all come out of the wood and are burned. On a typical wood fire (lets just imagine a camp fire or open fireplace) some of the volatile gasses burn, and some don't, they just float away. They are also a big part of what makes the smoke sting your eyes, and the smoke smell.

In the bottom of the gasifier, the left over "waste" is charcoal. That in itself can be used for all sorts of fun things. (Fuel, filtration, soil ammendment, etc.)

I really liked the size, shape, and look to this gasifier. I wan't to borrow it and take it camping.
