Carnegie Wave plans to
commission a “commercial scale” installation near Perth later this year, using a fully submerged
device that uses wave power to pump water to shore for conversion to electricity. And there are signs that big-company buy-in is starting, as evidenced by Lockheed Martin’s Australia project, which will use a buoy technology that generates electricity from the rising and falling of waves. Another company,
M3 Wave, plans to install a new device
just off the Oregon coast this summer. M3 will be using a pressure-based device, sitting out of sight on the ocean floor. As a wave passes over it, air inside the device is pushed by pressure changes from one chamber to another, spinning a turbine to generate electricity.
