Western Australia’s Stonehenge Metals is to trial using wave power to produce electricity at the port city of Bunbury.

For the trial, thirty floating buoys will be tethered together and supported by weights that will be filled with water and dropped on the sea floor. The buoys will drift up and down with the current to create compressed air that is then converted to electricity.

The company hopes to produce 45 kilowatts of energy from the buoys.

If the trial is successful, Stonehenge Metals plans to market the technology as a way to generate electricity, and possibly to aid in the production of fresh water, for small island communities.
