Wave Energy technology produces both clean water and clean energy

"Instead of generating electricity at sea and sending it to shore, a different kind of wave energy device is in the works in Australia, and it promises to deliver not only emissions-free electricity, but also emissions-free desalinated water." (Markham D,

the Pelamis wave energy converter. This is perhaps the most advanced device for long period waves such as those in the North Pacific ocean. The Finavera Ltd. company has a nice movie of their wave energy project proposed in Oregon. There are many different wave energy converters and no clear leader in technology. The power density from wave energy farms appears to be about 2 MW/km2. We expect wave technology to stabilize and become a reliable power source in about ten years, by 2020.
