ABSTRACT
The WM (wave mill) is
an efficient ocean wave energy converter. This technology will allow generation of electricity from the constant
wave actions. The WM made up of multiple OWCs (oscillating
water columns) rigidly connected to each other. Each OWC has an
inlet and outlet valve. When the water level inside the OWC rises, air is pushed through an outlet valve.
When the water level drops, air is sucked in through an inlet valve. A row of OWCs are connected by inlet and outlet air ducts. At
the end of each inlet and outlet duct is an air turbine which generates
electricity from the airflow created by passing waves. A 30 meter long
prototype was tested in Moreton Bay. The measured efficiency from wave to wire
was min 12.5% and max 36%. This efficiency is potentially much better than solar or wind power. The wave mill may be seen
as a viable green alternate form of energy. The WM is
scalable and has other flow-on benefits.
