Abstract
Liquid is continuously endowed with mechanical energy by continuously osmosing it across an osmotic membrane across which is maintained a substantial pressure difference of osmotic pressures. Continuity is insured by continuously flowing hypotonic liquid against and away from the hypotonic surface of the membrane, continuously flowing hypertonic liquid against and away from the hypertonic surface of the membrane, and continuously flowing permeate essentially limitlessly away from the hypertonic surface. The substantial osmotic pressure difference across the membrane is maintained, in part, by keeping the hypertonic liquid at or near saturation.
