1. A wave energy converter, comprising:
a positively buoyant buoy adapted to float adjacent to an upper surface of a body;
a hollow tube suspended from the buoy, the hollow tube including a constricted tube portion having a lesser cross-sectional internal area than a cross-sectional internal area of a mouth of the hollow tube;
a water turbine energized by water pressurized within the constricted tube portion;
a pod attached to the hollow tube and adapted to contain one of a non-corrosive fluid and a non-corrosive gas; and,
a generator positioned within the pod and operably connected to the water turbine.
