Gallery: WAVE ENERGY: Aquabuoy 2.0 Wave Power Generator

 

With most of our planet covered in water, wave-power is a promising source of renewable energy for the future. If more companies were trying to generate electricity from the energy of waves, we might have more renewable energy options to choose from. Last week we wrote about the worlds first wave-power farm in Portugal, but other countries and companies are jumping into the ring with new technologies as well. Finavera Renewables, an energy producing company with a focus on renewables, has recently launched the AquaBuoy 2.0, a large round buoy measuring 15 feet across to compete in the rapidly heated race to generate power from the sea. The Aquabuoy 2.0 is a large 3 meter wide buoy tied to a 70-foot-long shaft. By bobbing up and down, the water is rushed into an acceleration tube, which in turn causes a piston to move. This moving of the piston causes a steel reinforced rubber hose to stretch, making it act as a pump. The water is then pumped into a turbine which in turns powers a generator. The electricity generated is brought to shore via a standard submarine cable. As with the pelamis machines, the system is modular, which means that it can be expanded as necessary. Currently this technology is being tested off the cost of Newport, Oregon.

And that’s not all! Last week we brought you news of Portugal’s wave power plant, which was being created by using Pelamis machines off the coast of Agucadoura. Well, suffice it to say that it isn’t the only wave power plant being created off the coast of that country. Finavera Renewables has plans to build a second 2MW demonstration plant to be located in Figueroa de Foz, Portugal, which will be expanded to 100MW if the project is successful

    Hi I’m involved in a alternative micro power project on the coast of Bali and I’m searching for a system to harness the wave power which is constant and reliable. would any of you experts be able to advise me of a package that would be most suitable either 50m offshore or preferably to be incorporated into the seawall similar to the Islay power generator in scotland which harnesses the power through to blowhole.I would appreciate any opinions\ advice on this matter, thank you Dylan

    I’m involved in a small alternative power project in Bali and I’m searching for a micro wave generation package that could used, maybe similar to the Islay wave system or any other devices that could be used either close to the shore or incorporated as part of the sea wall, harnessing the air power through a blow hole. I would appreciate any advice or links to suitable sites, thanks Dylan

    I\’m also excited on wave power…:)

    I’m very excited about wave power. Some of the devices I’ve read about so far seem to be very complicated Rube Goldberg affairs, but I’d love to see some of these being applied.

    Hmmm, maybe a little harsh Moom… I take your point, maybe even agree, but these articles are on a blog, they can’t be heavily researched or it’d end up as a full time job. The occasional throw-away comment will always crop up, just roll with it…

    Any reewable energy geenrator that cannot produce dispatchable power is doomed – wind, photovoltaic ,
    and wave. Only the Seadog wave machine can geenrate power using hydroelectric technology and has
    an ultra simple, ultra cheap design that can produce power to compete with the imminent advent of solar thermal, which will make totally obsolete wind and photovoltaic solar technogies and also nondispatchable wave.

    “If more companies were trying to generate electricity from the energy of waves, we might have more renewable energy options to choose from.”

    WHAT?! Sorry, I can’t let that go. One click on the Wikipedia page for ‘wave power’ would have thrown up 33 companies trialing (or already offering) different wave-generation schemes – and that’s only the ones whose technologies are described! Are there 33 different designs for nuclear or coal power stations? No. Diversity is not the problem here, and nor is the lack of people trying.

    Just one more minute of research before you wade in with the throwaway comments, please!
