1. A hydrodynamic-pump, comprising:
a hollow buoyant reservoir;
an injection tube fluidly coupled to the hollow buoyant reservoir, the injection tube configured to impel water into the hollow buoyant reservoir when a portion of the injection tube oscillates vertically beneath a waterline;
a pipe having an inlet fluidly coupled to an interior of the hollow buoyant reservoir, the pipe having an outlet, and the pipe configured to remove water from the hollow buoyant reservoir;
a chamber fluidly coupled to the outlet of the pipe and to the hollow buoyant reservoir, the chamber comprising a fluid drain aperture;
an air ingestion pipe coupled to the hollow buoyant reservoir and to the chamber; and
an air inlet conduit coupled to the air ingestion pipe.
