Given that a powder in a confined space will explode when mixed with air and ignited, is it not feasible to have a propulsion system that mixes a fine powder with oxygen and ignites it repeatedly? (whilst in space rather than a lift off system)

...Or even as a terrestrial power source... surely very cheap fuel?
