Ramsey Sound tidal turbine installed

I do not recall Ramsey Sound depths but I wonder what depth it will be in, will it be marked in any way and may it cause even more turbulance in the sound?
 
As it's basically soaking up energy - and the supports are hopefully streamlined -I don't think it would cause more turbulence ?

Definitely the way to go compared to utterly silly wind turbines.

Indeed, I notice that it seems well inshore of the passage through

£16m for 400KW max output?

Tidal power is the most expensive going at around 3 to 8 times cost of natural gas per generated KWH.

If they'd invested half the money that has been poured into wind turbines we'd have developed cheap unlimited tidal power by now, generating 24/7 whatever the weather with computer models that could predict the exact power from any one station at any time in the future. I gues the tidal boys didn't have such good lobbyists :rolleyes:

Or, you know, it could be that developing robust technology that works for years on end with minimal maintenance whilst immersed at depth in a corrosive fluid that is full of little plants and animals who are trying to colonise every surface they can cling to, is slightly harder than building a wind turbine that lives on a hill where it isn't subject to rapid corrosion or fouling, and can be visited every day by people with minimal equipment and training.

Good point.

The fuel cost is very low. :rolleyes:

Indeed, and the figures I've seen includes all costs over the life of an installation including fuel or of course, not including fuel in the case of turbines. £16 million is the figure quoted for 400KW or about 150kettles if you like and that's presumably only the build cost. I think a diesel generator of that size would cost about £50K.

I can see how the wind lobby do it ;)

I often wonder if it's because it can't be seen by many people. Swathes of wind turbines cluttering up the lanscape make it look as if someone's done something, even if they're not moving. Something producing cheap, low pollution energy that's hidden away wouldn't get the kudos attached to it.

Couldn't agree more...

Which makes you wonder why people keep building these things http://www.4coffshore.com/offshorewind/

most interesting assertion about the price of wind power

I googled the price of a 400 KW Turbine

In many areas where wind farms are located, there are also some quite hefty currents. Whilst ROVing during the installation phase, I've wondered why there wasn't a tidal generator located around seabed level on the tower? A large proportion of the cost of a windfarm is the cabling, control platform and infrastructure, thus in a number of these places it could've been a logical step.
