and that it has only one principle moving part, the turbine, which is also located above water.

At 7 million $ a piece; producing 0.9MW are these contraptions considered cost effective ? Surely the formula should be: cheap=low-tech=durable.

DavidJ

That was my instinct when I first came across the design. However they must be doing something right (even if it is just the marketing) as they claim to be involved in a lot of projects.

i think this is a great idea. i have been waiting for it for a long time. lunar power is the "wave" of the future...sorry join us at www.censys.org

Variable pitch turbine? With full reversal on up and down stroke. That's a lot of moving parts and, to make things worse, in a high corrosion, saline environment. Sounds pretty awful to me.

It seems to me that they are trying to solve mechanically an issue that would be much easier to solve full solid-state at the alternator level. The recipe would be a very light turbine and alternator rotor for low inertia and an electronically controlled stator exciter and a solid-state converter behind to deal with the alternation in the up-down cycle.

I agree that the constantly changing turbine blade pitch is overly complex. Why not take a lesson from the Iron Age smithy who had a bellows that worked on the up and down stroke. By having a simple flap-valve that would allow air flow out over one turbine and in over another? They could even drive the same alternator with a simple non-corroding drive belt system.

Hopefully if this tech pans out, the price will come down. Wave power is promising, but tricky. Presumably the air pressure turbine greatly reduces the ability of the salt to get to the moving parts. It is a good that a lot of different wave power concepts are being tested. Most will be found impractical. Hopefully at least one design will be found practical.

Capacity utilization for a good site is going to be much higher than for solar and wind, and the temporal variability is probably decorrelated with wind/solar. So if this stuff can be made to work it would be a good addition to the time variable renewable component.

Al Fin

We are in need of a functional "energy island" approach to sea energy. Energy islands take all the low amplitude sea energy sources, combine them with baseload OTEC, and provide reliable power. At least on paper. Most wavepower-only approaches look like hunks of junk.

True, wavepower is promising, but current approaches to wavepower are not even close to what is needed. "If you build it, they [the suckers] will come--and pay." Only not always will they pay.

Kit P

There is a huge gap between planing, MOUs, and sustainable electricity production. Hydroelectric, geothermal, and biomass are the only forms of sustainable renewable energy so far. Wind is on the verge if the new machines can stand up top the elements for any reasonable length of time.

Anyone know the salvage value of wave contraptions?

pbean

Wave power is still in the early, let-one-hundred-flowers-bloom stage. I'm happy investors are willing to take such risks. Let's hope one or more healthy blossoms are left standing a few years from now.

Rob

Flap valves and such have been tried by various groups and found to be generally inferior. Variable pitch blades or a design known as the "Wells Turbine" are the favoured solution right now in terms of optimizing performance.

glad to have such an information about the wave power...thankyou.

The things which provided by nature are very powerfull. The power that develops through the natural waves is also very huge.. if we use that energy in a proper way definitely it will help.

I have had a problem I am growing some tomato plants and they have started to die on me. I think this was deliberate can anyone tell me what would kill a plant that's in a liquid form and is also odourless

I've been searching some information about natural gases for my special assignment when I came across this blog. For me, supporting the use of natural gases is the best way to lessen the carbon emission. I think the wave energy in Hawaii will benefits a lot of residences there because we know that place has a lot of beaches. So, I think wave energy fit the needs of that place. There are towns like in Northern California, solar energy have been used as an electric energy. There are lots of benefits from using solar energy. Northern California residences pay their electric bill in affordable price, and they're sure that the materials use in running a power plant is natural, because the main material use is the heat or the energy from the sun.

Thanks for the help, it was very useful.

Having it operate above water does make this an innovative and great project- soo much easier to work on.

You said could be operational by end of 2009, is it up and running yet?

A generator would be a principle part- but is it moving? They said the turbine was a MOVING part.

Good stuff, wonder how it's going.

Inspection of Work

Wave energy is produced when electricity generators are placed on the surface of the ocean. The energy provided is most often used in desalination plants, power plants and water pumps.

Construction Safety Coordination

The Oceanlinx turbine uses variable pitch blades which, with the slower rotational speed and higher torque of the turbine, improves efficiency and reliability and reduces the need for maintenance.

Wave power is less tricky and better than wind due to storage and we don' have to look at them unless we're diving.
