Abstract
A buoyant hydrodynamic pump is disclosed that can float on a surface of a body of water. Wave-driven oscillations result in periodic upward ejections of water inside a downwardly projecting tube that can be collected in a reservoir. Water within such a reservoir may return to the body of water via a turbine, thereby generating electrical power, or the device's pumping action can be used for other purposes such as water circulation, propulsion, dissolved minerals extraction, or cloud seeding.
Claims8
A hydrodynamic pump, comprising:
- an upper hull enclosure adapted to float at a surface of a body of liquid;
- a liquid collecting chamber at least partially housed within the upper hull enclosure, the liquid collecting chamber adapted to confine liquid and gas at elevated pressure;
- a liquid pressurizing columnar conduit extending below the upper hull enclosure, the liquid pressurizing columnar conduit comprising an ingress orifice disposed outside the upper hull enclosure, an injection orifice opening into the liquid collecting chamber, and an interior wall defining a liquid pressurizing surface adapted to pressurize liquid in the liquid pressurizing columnar conduit when the hydrodynamic pump oscillates vertically in the body of liquid to inject liquid into the liquid collecting chamber;
- a first effluent conduit configured to drain liquid from the liquid collecting chamber and having an external effluent port for discharging liquid from the first effluent conduit;
- and
- a first flow governor adapted to maintain a liquid pressure differential across the external effluent port.
