1. An oscillating water column (OWC), comprising:
a top body comprising a hollow cylindrical buoy column shape, the top body further comprising:
an open top end;
an open bottom end;
a chamber traversing between the open top end and the open bottom end, the chamber comprising:
a conical shaped skirt proximate to the open bottom end, the conical shaped skirt comprising a broader end and a narrower end, wherein the broader end of the conical shaped skirt resides proximate to the open bottom end and the narrower end of the conical shaped skirt resides distal to the open bottom end;
a portion of the chamber proximate to the open top end; and
a buoyancy volume residing between the conical shaped skirt and the portion of the chamber, wherein the buoyancy volume comprises a narrower water channel than the broader end of the conical shaped skirt and the portion of the chamber;
a power take-off system proximate to the open top end; and
an air channel proximate to the open top end and the power take-off system;
a bottom body comprising a bottom heave plate; and
a plurality of flexible tethers coupling the top body and the bottom body.
