I wonder if there is a way to make a combination rocket stove / solar oven. So you could use a small amount of fuel if clouds (or timing) make solar unavailable. Or use both to obtain high heat. You could use a parabolic trough to bring in heated air into the intake of the rocket stove. You could also use a fresnel lens to goose the heat at the rocket's output.
