SeaPower Promises Emission-Free Power and Water

Austrailia is working on a desalination plant due to the water shortage they are
experiencing.

Perth, Western Australia, is considered the most remote city on the planet. And
one thing they are running out of, like much of drought declared Australia, is
fresh drinking water.

They are currently working on a plan to cut the amount of energy it takes to
run it. They have considered using the wind. There is a new alternative that is
being looked at by inventor Alan Burns. He teamed up with Seapower Pacific
(Carnegie) who have invested $10 million to get his idea on the market. His
invention is called CETO.

How Does CETO Work?
Matter Network has as good a description as any of how CETO works:

Long columns — multiple individual submerged units — are anchored to the
sea floor, and sway in unison with the motion of passing waves. The columns drive
pumps, which in turn pressurize seawater that is delivered on-shore through a
pipeline on the ocean floor. Each 125-unit Ceto farm can make enough power for
15,000 households.

The CETO wave power converter is the first unit to be fully-submerged and to
produce high pressure seawater from the power of waves.

By delivering high pressure seawater ashore, the technology allows either zero-
emission electricity to be produced (similar to hydroelectricity) or zero-emission
freshwater (utilising standard reverse osmosis desalination technology). It also
means that there is no need for undersea grids or high voltage transmission nor
costly marine qualified plants.

CETO units are fully submerged and permanently anchored to the sea floor meaning
that there is no visual impact as the units are out of sight. This also assists
in making them safe from the extreme forces that can be present during storms.
They are self-tuning to tide, sea state and wave pattern, making them able to
perform in a wide variety of wave heights and in any direction. CETO units are
manufactured from steel, rubber and hypalon materials, all proven for over 20
years in a marine-environment.

The CETOs are relatively simple to manufacture and transport. An independent
technology assessment says the concept has significant potential and more trials
are now underway with commercial units planned for 2009.

Way to go! Now this is way cool!

    If we looking on this SETO on the air, it looks like a giant sea snake, isn’t it, Linda?

    As I knew, wave energy is amongst the top ten renewable and eco-friendly energy…

    hi Wilson … No, I do not see a giant sea snake just a bunch of bobble heads. Much better for me as I hate snakes!

  3. GreenBuyDesign Says:

    Would you consider doing a guest post on our blog? This is great information!

  4. Barbara Says:

    Hey Linda,

    Another terrific idea…I hope it comes to pass, the sooner the better!

    Hi GreenBuyDesign … Sure! I will contact you!

    Hi Barbara … I hope so as well. They need lots of help!

  6. David Says:

    Yep, this is pretty darn cool. And for those who hate to see their energy being generated, I guess hiding the bright idea makes sense. Well, I hope this has no hidden downside – perhaps it will decrease wave intensity at the shore line a bit, but that seems worth it!

    Hi David … It seems that there are no down sides except maybe where it is placed. Do not know if boats, divers, etc. could bother them.

    Tag! 🙂

    This is fantastic! I hope they are working on something similar in the US. My only real concern is the affects it may have on sea life.

    Wow, what a great idea!

  11. Linda Says:

    Hi Patricia … so far no effects on sea life or humans. No, I have not seen or heard anything like this in the U.S.

    Hi Stefan … It is really cool and they are in a final testing stage so it should be looking pretty good for implementation.

  12. Diana Rupert Says:

    really good idea to solve the problem. Hope it will work well.

    Hi Diana … It will as they are picking sites now to start.

  14. Barbara Swafford - Blogging Without A Blog Says:

    Hi Linda – What a terrific idea. It could change lives not only in Australia, but all over the world if it works. Fingers crossed.

    Hi Barbara … Mine are crossed as well. They really need this to improve their water supply.
