Still in the research and development stage, it has built a large test facility 20km (12 miles) inland from the Queensland coast. In the middle of a 3.6 hectare (nine-acre) man-made pool, a 1,400-ton, compressed air, steel pump goes up and down every six seconds. Powered by electricity, the pump creates 360-degree waves up to 8ft (2.4m) high, at a rate of 2,000 per hour.
