You are talking about light mill. It does not work in vacuum. Light/photon has no momentum. If light has momentum, light mill will work in vacuum. Light is gravitational vibration force between separated atoms/matters. Gravity is the force carrier. Mass/atom m vibrates at f will produce f x m x c gravity/force/gravitational momentum at vibration direction. If there is mass/matter in the direction, it will sense the force and energy is transferred that way.
