Abstract: An engine for powering by water that includes a stator, a rotor rotatably mounted in the stator, and a plurality of blades movably mounted in the rotor. The stator has a throughchamber. The rotor is rotatably mounted in the throughchamber. By virtue of a throughbore in a top plate of the stator being offset from its longitudinal axis, a throughbore in a bottom plate of the stator being offset from its longitudinal axis, and a throughbore in the rotor being along its longitudinal axis, the rotor is offset in the throughchamber and has only one tangential point contacting a circular periphery of throughchamber at any one time as it rotates in the stator. The rotor rotates clockwise in the stator, by steam applying a greater force on a blade of a pair of blades of three blades that define a communicating power chamber that protrudes further than another blade of the pair of blades, by virtue of the fact that it presents a greater surface area exposed to the steam.
