The OWAP is a point absorber wave energy converter (WEC) using an oscillating air column to drive the electricity producing part of the device. As ocean waves pass through the float area, the float rises and falls pushing a piston through a cylinder filled only with air.
As the piston drives the air first down then back up it pushes air through a bi-directional air turbine on the bottom of the cylinder then through a bi-directional air turbine on the top of the cylinder. Electricity is produced by both turbines. This electricity is then sent to the mainland via an underwater cable.
