Wave Power Generator From Some Guy's Basement

Harnessing the power of the cialis 20 waves to create energy for the masses seems to be taking several inventive modes these days. One idea from a company called Swell Fuel targets the use of a lever operated device.

Swell Fuel's "Ocean Energy Converter": Using "a lever operated pivoting float anchored to the ocean floor, Swell Fuel's ocean energy converters are designed to withstand pounding waves. The wave motion triggers the movement of the lever, which in turn produces electricity.”

Swell Fuel hopes to buy cialis 5 mg produce some 350,000kW per year per unit and says that by linking the units together, one could potentially provide a significant source of electricity. The company already has one patent issued and has apparently already licensed the technology in five countries, with several others expressing interest.

That's pretty impressive, as Swell Fuel seems to be just a guy with some PVC pipe and a dream.

Portugal Boasts World's First Commercial Wave Power

It's really satisfying to see new green technology go from the viagra cheapest price generic concept phase to reality, and today we have something to get excited about. Ocean Power Delivery, a Scotland-based company, has just announced that they will be installing the world's first commercial wave farm off the coast of Portugal. This plan has been floating (sorry) around for a while now, but it's happening now. October 2 was supposed to be the launch date, but due to bad weather, it will have to be briefly postponed.

The wave farm looks essentially like a group of massive snakes, but these behemoths, each the size of usefull link a small commuter train, can produce upwards of 750kw each! The farm will have 3 units, and thus have a capacity of 2.25MW, supplying electricity to roughly 2,000 homes. So how do they work?
The machines are essentially a series of semi-submerged tubes which are linked to each other by hinged joints. It is these joints which are the trick behind the system. The joints act as a pumping system, by pushing high pressure oil through a series of hydraulic motors, which in turn drive the cialis without perscription electrical generators to produce electricity. Needless to say the machines are moored to the ocean bed. To give you an idea of the size of each module, the 750kw prototype, is 120m long and 3.5m in diameter. Each of these modules is composed of three individual 250kw tube.
In addition to Portugal, Ocean Power Delivery has just announced a $8.2 million wave farm project in Orkney, producing a total capacity of 3MW.

Finavera Deploys 40 ton AquaBuOY 2.0

Finavera Renewables has just successfully deployed its second generation AquaBuOY, a wave generation plant that weighs nearly 40 tons and is propecia 1 mg on sale 75 feet long. Only about ten feet of levitra generico the device shows above the water. As the buoy rocks up and down in the surf, it generates power with an internal generator.

That power can then be shipped back to shore via an underwater transmission cable. The bouy's huge size allows it to canadian drugs cialis harness a great deal of the moving water's massive energy. No word, however, on how much energy each of these will produce. But, as with wind and viagra blister 4 solar, wave power only has up-front costs. Once the project is in place, the "fuel" that creates the power is free.

Finavera alraedy has about 250 megawatts of wave power planned or under development in America. The AquaBuOY 2.0 wave farm off the coast of Oregon could be underway as soon as 2010.

World's Largest Tidal Turbines

Marine Current Turbines has begun constrcting the largest ever tidal plant and says that it will be complete before the cost viagra end of the year. The two giant underwater tubines will, together, produce 1.2 megawatts of power off the coast of Northern Ireland.

While this isn't really a significant amount of power, it does mark a bit of a landmark for tidal power. The project is simply a demonstration of cialis delivery in 5 days or less the potential of the technology. There is an awful lot going on in tidal power these days, and it looks poised to begin the kind of explosion that we started seeing in wind a few years ago. The early adopters, like Ireland and the UK, will be important to watch.

Tidal Power Goes Snakes and Bobbers

Recently on EcoGeek, we told you about some breakthroughs in harnessing the tide to produce electricity. We also filled you in on the underwater turbines that were plopped into the East River, and about the good things to come below the discount levitra online surface of the San Francisco Bay. Now, two more developments can be added to the list of sea worthy power plants: giant sea snakes and EcoGeeky bobbers.

While the Loch Ness monster is still at large, sightings of Scotland's newest sea beast, the Isle of Lewis giant metal snake, have been confirmed. A Scottish company, Camcal, has riveted together three 450-foot wave-powered energy snakes in what they call the Pelamis project. As the hollow tubes slither across the surface of the ocean, they produce electricity via generators in their joints. The plan is to build enough Pelamis snakes to eventually generate 2.25 megawatts. This BBC article outlines the maiden voyage of the snakes on their way from the Isle of Lewis to Western Isles for Portugal.

Stateside, tidal pioneers in Oregon are opting to go with a large yellow bobber design. With a series of what they call permanent magnet linear generator buoys, professors at Oregon State University have implemented an elegant design that features a metal coil within a bobbing buoy surrounding a magnetic core that tethered to the ocean floor. As the coil jostles around the internal magnets, ocean electricity is zapped two miles to the Oregon coast.

In the wake of a recent study that bashes some renewable energy sources for using too much land, I say bring on the snakes and bobbers!
