This is how rocket stoves work. They are more efficient because they burn the gases from the wood not just the wood.

Yup. Even after the cost of gasifying the wood the net energy is higher, mainly because at the end there is little char. Normal open air burning produces a lot of carbon and other junk in aerosol form. Gasifying first burns the particles, which contain a lot of energy still.
