This was found to be too expensive, so Azura are now working on a smaller-scale device to produce both electricity and potable water.

This enables it to extract power from horizontal (surge) as well as vertical (heave) wave motion.

[12] The wave motion is captured by the circular rotation of the floating mechanism, and translated to crankshafts within the Azura.

A second prototype was then installed in 2012 for a 6-week period at the Northwest National Marine Renewable Energy Center’s test site off the coast of Oregon in an open-sea area.

[2] Northwest Energy Innovations (NWEI) used information gathered during the test in Hawaii to further develop the project.

With the Department of Energy providing an additional $5 million, NWEI planned to modify Azura to increase its efficiency and improve reliability.

Instead the company are targeting off-grid markets such as aquaculture and remote island communities that typically use competitively expensive diesel generators to provide electricity.
