It’s essentially an artificial blowhole according to the company CEO. They say the device uses resonance to make the most energy out of the water that washes into it, by operating at the natural frequency of the waves, and claim it’s ‘120% more efficient than a conventional device’.

Wave Swell Energy plans to install a commercial scale wave energy plant in the Bass Strait, off King Island in Tasmania, reports Tidal Energy Today.

Wave Swell’s series of one-megawatt generators will cost up to $7 million to build, and at peak times will provide up to half the power for King Island’s 1,600 residents, according to the Australian Maritime College (AMC).

The Australian-based wave energy developer said it expects the cost of wave power to be less than 10 cents per kilowatt hour when built at scale.
