Rocket Stove without the shearing, plasma or bandsaw cutting steel and welding, nor the portable aspect.

Almost, but you've got no secondary air source, post combustion.

Good idea. Diagram not to scale.

This appears to be a survivalist image.
Beyond that, however, it has to do with accessibility. Consider the most accessible form of energy, other than solar, is steam. All one needs is a fire and a container. Make it more sophisticated, and the steam can be contained and used to drive a piston, an arm, a shaft, etc. This 'Dakota Fire Hole' is an accessible rocket stove, and the design predates.
