This water powered hydraulic ram, when housed in a supporting water-tight structure deep within a moving body of water, functions essentially as a four cycle engine with water as it prime mover. It is a linear motor, just as if it were powered by ordinary fossil-based fuels. This invention harnesses the force of moving water and the pressure of water at a depth and becomes a prime mover whose output is hydro-power. When water is confined in a solid body and its force is applied to the surface of a piston, that force is transmitted equally, in all directions throughout the fluid or gas in the form of pressure. It is a machine. This characteristic observes “Pascal's Law”. The component parts of this linear motor are a hydraulic ram cylinder, sliding ram pistons, a Venturi/Eductor jet pump, electronic piston positioning sensors, solenoid controlled valves and process program software. It is positioned to face an oncoming, irresistible downstream water force. It may be either singular or in plurality as an array, this being a site adaptation design issue. Its purpose is to transform the limitless energy from moving water. It is an integration of existing technology of various fields. It is applicable to any comparable moving fluid source, particularly water. The coastal Gulf Stream and other ocean currents provide ideal environments as infinite sources of renewable energy. Being operative in an infinite body of seawater, the highest priority application should be to apply pressure to seawater and pass it through a reverse osmosis membrane to remove the salt, The product would be unlimited quantities of potable, fresh drinking water.
