Carnegie Wave Energy is planning to open the world’s first zero-emission wave powered desalination plant on Garden Island in Australia. Using the Perth company’s proprietary “CETO technology,” the two megawatt pilot project will operate with multiple submerged buoys tethered to pumps that funnel pressurized water to turbines onshore. There the water can either be harnessed to create electricity or to run and supply water for a reverse osmosis desalination plant.

Named after a Greek goddess, the CETO wave power converters are the first to be fully submerged under water, keeping them safe from the effects of major storms and reducing visual impact. The project on Garden Island in Western Australia will be a grid-connected, commercial scale operation that will demonstrate the technology’s viability, record its interactions with the environment, and help provide fresh water in an accordance with the West Australia Water Corporation.

Desalination is an important part of Perth’s long-term strategy to maintain a supply of clean drinking water and the Carnegie Wave Energy technology will secure a means to provide this precious resource without relying upon energy-hungry machinery. Instead, by creating its own power, the CETO infrastructure can cut down on greenhouse gas emissions while also generating electrons and purified water. The project is expected to begin construction in 2014.

    Carnegie ( name chosen to make them sound “RESPECTABLE” have been gouging money from taxpayers and investors around the world for years.
    The idea is ridiculous and does not/ will not/ never will work.
    The desalitation crapola is just to disguise the fact that it doesn’t really work and to spin out the charade for a few more years whilst most of the money goes down the executives trousers.
    In short….it is a LOAD OF OLD BOLLOCKS!

    One of the first desalination systems (10 m3/d) run with
    wave power was installed in Kerala, India and reportedly
    consumed 1.85 kW h/m3 with a 25–35% recovery. Please read this MIT publication:
