Abstract: The present invention discloses a pressure converter system for sustainably forcing saline water through a semi-permeable membrane, comprising a hydraulic oil pump, a hydraulic oil cylinder comprising pressurized oil generated from the hydraulic oil pump, a sustainable energy source for powering the hydraulic oil pump, a saline water cylinder containing saline water, wherein the hydraulic oil cylinder and the saline water cylinder are connected using a piston and an electrical circuit for determining a direction of movement of the piston. This system may be developed to a stand-alone desalination facility comprising a ducted windmill that can harvest energy from a wide range of wind speeds, especially very low wind speeds. Because of the above, the present invention successfully converts mechanical energy to high pressure that is required to produce fresh water from saline water.
