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 viagra testimonial has a rotor diameter of generic viagra pill 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 cialis for daily use 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.

Impressive, but...

....why wasn't the US the country installing the largest tidal terbine? Maine has one of the largest tidal loops in the world...over 50 feet. Seems strange that the we choice buy discount viagra online US can't lead in these things. Guess when you are paralyzed by an economic downturn job creating energy initiatives are not allowed!! Who would want to take money away from the fossil fuel producers?!!
we have experience in building things underwater.... maybe not the best type though?

The last line really rings true in light of the deep horizon disaster. The ocean can be a tricky thing to operate in. However, I surmise that if all the investment in deep sea oil exploration was channeled into tidal energy, we would be decades ahead in this area.

Hey! I left a comment, but it says there have been no comments. What gives?
Think Gulf stream
written by Matt, August 13, 2010
Think of canadian generic cialis online placing these all along the east coast in the gulf stream. It flows 24/7/365. There is a large current on the west coast too, just don't recall it's name. I guess draw back is you have to go off the coast a bit more to be in the stream.
Why be a leader in tidal power
written by GoSolar, August 14, 2010
when we've got all that oil and coal and nuclear? The US energy industry is dominated by these interests and pretty much still has the cheap cialis canada congress wrapped around their fingers.

Until we can break the stranglehold of the fossil fuel industry, the US will continue to lag in energy efficiency and conservation, and in the design and buy viagra without prescription implementation of renewable energy solutions.

Also, remember that even this tidal power setup is levitra presciptions all about maintaining a utility perspective. THEY own the power, YOU pay them every month. There is little momentum for helping individual users become energy independent. That's where WE all have to come into play.

@Matt : Think Gulf Stream
written by fred, August 15, 2010
Think about what might happen if there was sufficient energy removal from the Gulf Stream to it's cool generic cialis sale effect its flow. You might end up with a catastrophic change in ocean current circulation resulting is major unintended consequences to climate.

Does anyone know the speed of the Gulf Stream? Look it up. Compared with cut in speeds of tidal turbines I think you'll find it's pretty slow.

Tidal energy generation currently needs headlands, islands, channels etc. to focus the power, accelerating it up to the cut in speeds of the current production tidal turbines (ie 2.6m/s in above article). These spots are the sweet spots where the first generation of tidal turbines will be tested. If they make it into mainstream volume production and become more efficient, more cost effective, etc. then they'll start working down to the lower speed sites of large ocean currents. Just the wow it's great levitra buying same way that the wind energy industry has developed. Tidal is currently 20-30 years behind wind energy industry but will potentially develop faster due to modern CFD, production technology and dual looming crises of cheap tramadol free delivery peak oil and climate change.

Re removing large chunks of the Gulf Stream flow: Yip. It's been thought of. Look up papers on resource assessment and impact assessment for tidal schemes in Bay of Fundy, Puget Sound, West Coast of Britain, Pentland Firth, Martha's Vineyard. Basically the amount of energy we can currently capture is a drop in the ocean if you'll excuse the pun. However you're right, if this technology goes ahead too fast with no planning there are pitfalls to avoid. We are a looooong way from that at present.

Hope that helps.

Weighing in

This machine actually weighs in at 1300 tonnes (rather than the 130 tonnes in the article).

This suggests that an economically viable version may be some way off.
what about the marine life
written by Lula, August 26, 2010
Are there any protective boundaries being placed around these turbines to guard marine animals from being sliced and diced?
Too dumb to fail
written by Ray, August 27, 2010
I think we really need to cheap cialis no prescription get clobbered in the head a few hundred more times before we turn this ship of fools around. We need more Deepwater Horizon, New town creak, Exxon Valdez, coal and nuclear accidents before we realize this is not what we want. We only react in a fear based senerio.

Here's a link to what's going on RE tidal energy in Alaska. There's lots to figure out, regarding impact on whales, fisheries, turbulence in the shipping path, etc. But things are moving...

I am also concerned about the effects of tidal turbines on marine life? How does this giant turbine interact/detract/contribute to the biodiversity of cialis kanada the habitat it essentially invades? I am all for alternative energy and renewable resources, but at what costs? Using less energy seems to be the only viable solution to the crisis we now face.
