World's Largest Tidal Turbine Getting Anchored off Scotland's Chilly Coast

wont last... salt will eat it up within 5 years... good college try...

Give the boys in Metallurgy a little credit. This is brilliant tech, pure green. Only a Republican oilbiz lackey could object.

Salt will not eat it up if the blades are made of composits, like Doty-Rotol aircraft propellers. Gaskets will keep the sea water out of the generator, whose housing can be made of composits too. Sounds like a good idea to me. Although the tides pause before reversing, they will generate electricity forever, because tide don't get used up.

Curious... wonder what effect all these sea and wind devices will have on the movement of water and winds all over the world as we build more and more? Imagine 50 yrs from now and we discover we've slowed down the earth's rotation? or some other 'imaginable' dramatic.. unfixable.. impact????

If you go to www.openhydro.com you will see another underwater turbine in development and one already tested in the same region of Scotland is already hooked to the grid there. This type turbine also has been put into the Bay of Fundy offshore from Nova Scotia. These turbines are still in the developmental stages and some bugs still have to ironed out of them, but they look very probable for the future.

What a waste of money ! Even Queen Elizabeth ordered one dinosaur just like this one for the palace; and here our start-up company has invented 8 foot bladed turbines that can be transported on a pick-up truck, that put out four times the generated power than this and the GE $2M 1940's technology wind turbines and one would think that our governement would be intetrested ? No, after attempting to contact the members of the commerece and energy commission, (Congressman Ralph Hall, then Congresssman Burgess), and even Secretary of Energy - Mr. Chu, we've discovered that American polititcians will not embrace Green Energy too soon, for we are too steeped in fossil fuel interests !

Our government went so far as setting up this Mr. T. Boone Pickens as our icon of "why it doesn't work" to fool us all:

It's been all over the news how Picken's $2 BILLION dollar wind-farm, (consisting of 667 GE turbines, on 110 acres in Pampa, Texas) has "transmission issues" and so I landed on Picken's doorstep last Septemeber, only to discover that T. Boone spent ONLY $60 MILLION of his own money on this project, and guess who foot the bill for the rest ?....and it sits idle to this day !!!

Pickens was not interested in our technology - even though our inventor has already implemented inventions that are in use at Boeing, The Pentagon, and yes, even in the White House ! In return for playing the stooge, Pickens was appointed chairman of the world's largest natural gas board, and along with his many oil interests, he happens to own quite a bit of natural gas land ! SURPRISE !!!

Anyone interested in additional and verifiable information may contact me at consultantmail@aol.com.

And even slack tide can be addressed with a flywheel system that stores a percent of the kinetic energy until maximum rpm is achieved after the turn.

why so much time, money, and energy [no pun intended] wasted on inefficient technologies such as turbines when the Bloom box exists? people wake up and check out cheap and efficient electrical production which also doesn't take up a lot of land or interrupt the ecology. Google Bloom box !

Stand still, laddie!

We've had submerged hydro machines for years and some in brakish water too. They hold up well and some take a lot of stress. Pump storage machines take a real beating but operate for years and years within its predicable repair cycles, No reason to believe a submerged turbine would behave any different. Now if it were exposed to air on a continuous cycle, I might be nervous but submerged might do just fine. (look at our submarines and their propellers - how often do you think they are removed and repaired? Not often if at all.. It is materials and cathodic protection which will insure the unit will remain sound.

Cathodic protection in the form of sacrificial anodes like on boats or (most likely) some even better technology than used to protect the thousands of seawater immersed applications we already employ today. They have the know-how to build this monster..... I seriously doubt they missed the need to deal with corrosion... or a plan on how. Think Submarines.

This is to Mike who commented that the Titanic is been sitting at the bottom of the ocean and that still standing, well Mike , either you are stupid or misinformed, fyi, the Titanic is crumbling due to the effect of the salt water, and some day it will be a pile of rubble.

This thing will make the chop-o-matic look like a wimp when it slices and dices a whale and a few dolphins. Seafood Tartar anyone?

Mike the Titanic has not rotted away because in order to rust or rot away it needs OXYGEN, something thats not at the bottom of the ocean floor!

I think its awesome and a better idea than coal or oil. Oh, and the titanic already is a pile of rubble and has been since 1912.
