The device is a floating OWC chamber with a turbine connected to a generator.
The air pressure within the chamber increases with the rise of the water level resulting in the flow of air through the turbine. Conversely, as the water level in the column reduces, air is drawn into the chamber. The power take off device, a pneumatic turbine, is uni-
