  • Patent number: 6189811
    Abstract: A portable water-pumping system comprises a water-tight case with a hinged lid. A deep recess in the lid allows a photovoltaic array to be nested inside in a protected position. A gel-cell battery operates a high-pressure water-pump and both are carried inside the case. A trigger-operated water nozzle and a pressure switch allow automatic functioning of the water pump. A non-collapsible water-suction hose includes a strainer to prevent clogging of the pump. A cigarette-lighter power cord allows near-continuous and heavy use when a source of 12VDC power is available from a car, boat, plane, or other vehicle.
