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.

The technology, called CETO after a Greek sea goddess, is being developed by Carnegie Wave Energy Limited, and their upcoming 2MW pilot project near the Perth Wave Energy demo site will be the first wave powered desalination plant in world.

According to the company, the system is "the most efficient and cost effective way to desalinate freshwater from wave energy," because it doesn't need to send electricity to shore and then convert it into mechanical energy for pumping, which would involve losses in efficiency and additional costs for equipment and maintenance (the transmission and pumping equipment).

interesting and sounds pretty good, except for the fact that your pulling water from the pacific which is now a radioactive sewage dump.

G,day Mate. Negative on your Pacific ocean comment. Perth is on the other side of the island. The Indian ocean side. The problem will be when the pacific ocean is pushing harder than the Indian ocean at their meeting point off North West coast of Australia. When that event happens the Pacific ocean pushes right down the west coast of Australia and on into South Australian costal waters where we farm shell fish and tuna. That is when your radiation comment will come into play. . Hmm, wonder if we will be marketing glow in the bloody dark tuna and radiation red oyster shells.

The concept looks good.

Anything with moving parts in the ocean always raises the question in my mind about maintenance costs. They can be hard to predict exactly, but implementing the technology and measuring the actual maintenance costs is one way to do it, then figure out how to lower them.

The world needs more energy and drinking water so if this provides both economically, it's great. The question is how economically can it do this (after all costs, including maintenance).

This combination technology is very impressive in its concept. I love the idea of using wave energy to clean the water, as well as to produce electrical power. So efficient and smooth as an idea!


As for the comments about radiation in the sea? It will change the face of your average beach front barbecue thats for damn sure. "Time to get the dinner on then eh? Right, pass the beer, the charcoal, the meat, the Hazmat suit and the lead underpants..."
