Abstract:
A system for pumping water from a well drilled into an underground water source, said system operable in association with a wind mill, said wind mill having a tower frame, a wind driven turbine positioned at an apex of said tower frame, and a reciprocating pump shaft operably connected to said turbine and positioned between said turbine and the ground, the system comprising:an air pump mechanically linked to said reciprocating pump shaft and operable by the direct reciprocating motion of said shaft, said air pump positioned within said tower frame and having an air outlet port; an air conduit connected to said air outlet port of said air pump and directed into said well; and an air-lift fluid pump positioned within said well and said underground water source, said air-lift fluid pump comprising a fluid conduit having a first end positioned below the ground, open to said underground water source for receiving a flow of water there from, and a second end extending above the ground for delivering a flow of water thereto, said air-lift fluid pump further comprising an air injection port positioned proximate to said first end of said fluid conduit, said air injection port connected to said air conduit for delivering a flow of air into said fluid conduit; wherein air from said air conduit mixes with water from said underground water source at a point within said fluid conduit near said first end thereof, thereby causing a buoyant water and air mixture to flow from said first end of said fluid conduit towards said second end thereof.
