India Getting 50 MW Tidal Power Project

Asia's first commercial scale tidal power project is cialis generico being built off the coast of India.  The project will initially have a capacity of 50 MW, but could eventually be scaled up to well over 200 MW.

London-based Atlantis Resources, the company responsible for the world's largest tidal turbine located in Scotland, is building the project in the Gulf of Kutch.  Construction is planned to start as soon as this year and should be completed by 2013.

A recent survey by Atlantis shows that the gulf has about 300 MW-worth of potential tidal power and the construction agreement between the company and India's Gujarat Power Corporation Ltd. allows for up to 250 MW to be developed there.

Tidal power is a strong, reliable and predictable source of viagra online without a prescription renewable energy, but it hasn't been harvested as much as solar or wind power, mainly because of its high initial costs.  But it's starting to get more attention -- tidal turbines have been installed in rivers in both New York City and Paris and huge tidal power projects are being developed off of Scotland's coast.

Power for the Big Apple from the East River


In-stream power is getting another shot at commercial viability with a proposed installation in New York City. Verdant Power has applied for regulatory approval for an installation in New York's East River. Research installations have been tried here, as well as in Detroit and Minnesota.

If the Roosevelt Island Tidal Energy (RITE) Project is approved and installed, it would represent the first in-stream power installation connected to the commercial power grid. The project will expand the viagra in spain existing field of 6 full-scale research turbines in the East River to 30 turbines which would provide up to 1 megawatt of electrical power to the grid. RITE will utilize fifth-generation turbines, which Verdant has been developing and improving over the previous decade.

In-stream hydropower is appealing because it is less erratic than wind power, which depends on just try! next day cialis the weather. Part of Verdant's research has also been to investigate environmental effects of the turbines. Research has shown "no observed evidence of buy online viagra where increased fish mortality or injury, nor any irregular bird activity in the project area. The data demonstrate that fish avoid zones of impact with Verdant Power’s system and populate inshore areas." These turbines will be more expensive to prescription cialis install and maintain than wind turbines, but the power can be generated close to the population centers where it will be used.

Massive New Tidal Turbine is World's Largest


The world's largest tidal turbine, standing more than 5 stories tall, has been unveiled in Scotland before being installed in the waters off Orkney later this summer. The Atlantis Resources Corporation's AT-1000 turbine is 22.5 meters (73 feet) tall and has a rotor diameter of 18 meters (59 feet) and weighs 130 tonnes. It will produce 1 MW of power from a water velocity of 2.65 meters (8.7 feet) per second. This is considerably larger than the river turbines other locations have proposed.

"The giant turbine is expected to be environmentally benign due to a low rotation speed whilst in operation and will deliver predictable, sustainable power to the local Orkney grid." The turbine blades will only turn at a rate of 6 to 8 revolutions per minute.

The tidal turbine project is connected to a plan for a data center located in northern Scotland and intended to be powered entirely by tidal power. Tidal power offers a predicatable, reliable energy source. Water is 832 times as dense as air, making it possible to draw similar amounts of energy from a much smaller turbine unit. However, the harsh marine conditions that underwater equipment must face has made development of tidal energy a slower process.

Paris Putting Turbines in the Seine

The Seine, the scenic river running through Paris, has inspired artists, attracted tourists and served as the soul of viagra profesional the city, and now it will also be a source of renewable energy.  Paris officials have announced a plan to place river turbines beneath four bridges on the Seine.

The Pont du Garigliano, Pont de la Tournelle, Pont Marie and Pont au Change will each have two turbines installed underwater at their base.  These bridges were chosen because the speed of the current accelerates in those locations.  While river currents don't produce the kind of electricity that wave power can, the current-harvesting technology has come a long way and more devices are being introduced that can generate energy from even the slowest moving waters.

City officials have put a call out to power companies to come up with the best plan for installing the turbines, with a winner being chosen in January and installations starting next spring.

Oyster Offshore Wave Generator Is 2.5x Better Than Predecessor


Power generation from waves continues to develop as Aquamarine Power has unveiled its new, second-generation Oyster 2 wave power generator. According to the company, "The new 800kW device will measure 26 metres by 16 metres and will deliver 250 per cent more power than the original Oyster 1 which was successfully deployed at the European Marine Energy Centre (EMEC) in Orkney last summer." A test installation is planned for 2011 and will use three wave devices connected to a single power generation station to produce 2.4 megawatts of electricity.

Like the Pelamis wave generator (now, sadly, sitting on the shore for lack of maintenace funds), the Oyster rides on the surface to harness wave power. This means that Oyster cannot coexist with surface vessels, unlike other underwater systems. But, instead of housing the viagra one a day generator at sea, where conditions are harsh and maintenance and we like it female levitra pills repair are costly, the Oyster system harnesses wave power to drive hydraulic systems and on-shore turbines to produce electricity.

The new Oyster incorporates many improvements over the original design, including simplified construction requiring less steel to produce and design to enable easier mass production.  Aquamarine Power expects to deploy Oyster in farms of 100MW generating capacity or more. An animated Oyster video shows more about how the system operates.
