Survival of the fittest.

jk aside, wind turbines look krap and I think that's it's ridiculous that there is hardly any infrastructure in place to store the energy that they produce!

I'm sure that there are a few peopel on here that have worked in the green/renewable sector, if so why can't we harness the power of the ocean? Twice a day the moon moves a scramferious amount of water about, Shirly we can capitalise on the tides of billions of tons of water sloshing about?

 

 

Except anything power generating with moving parts in a marine environment has a very limited life due to;

(i) The limited number of materials that are both mechanically strong while still being  unsusceptible to salt water/salt laden sea air  corrosion.

and,

(ii) The insurmountable issue with barnacles and other such sea life, that get in everywhere, escpecially there is a moving current of water to provide them with nutriants.

(iii) Never mind the destructive power of storms, likely making construction cost prohibitive.

That's my thoughts too but ships seem to have a 30+ year lifetime as do some commercial airplanes, I wonder how long modern multi megawatt wind turbines will remain in service.

If we burn all the cats in a biomass boiler we would get some power and a few more birds to keep the wind turbines spinning for an extra few months a year! Winner winner 

And no catsuit in my garden!

Sorry but yet another post that is long but factually just not anywhere near the mark. 
The technology you allude to is already in place and working. The absence of tidal lagoon power generation in the UK is purely and simple a lack of political will. As I said previously if you are actually involved in an industry you tend to pick up on what’s possible and what’s actually happening. You might want to do a bit of research on “ pumped hydro” it’s already established and operational in a number of locations.

Thanks, that shows my point perfectly, and others about off shore tidal generation. This single scheme you found out to highlight - produces the energy for 12,000 houses (though there is a potential to increase this). A single, new 8MW wind turbine will produce, alone, the power for 16,000 houses (with both running at full capacity).... Tidal power isn't the answer to generating electricity for the UK at the moment.

 

You mention pumped hydro as a storage medium, yes, it exists but not in the scale required to power the whole UK if the wind drops on cloudy days - I might have mentioned that above...

Edit here to reference pumped hydro storage. UK has pumped hydro storage of about 2,800 MWh (which is a lot), but use about 1TWh daily.... which is lot more

I figured you’d try and drag it down to the level you are comfortable with. Especially once you were called out again. I mentioned that particular site as it’s one I’ve dived on and am familiar with no other reason, you can’t beat real time experience or knowledge on a subject I find. Talking about knowledge I’ll just pop a bit of info  in that might help you to work out that pumped hydro doesn’t need sun or wind, rather it does its thing at off peak periods. I’ve had an amusing discussion with the Norwegian guys on the vessel when trying to explain to them your theory of using wind and solar to pump water.

I think this makes more sense to me with the guidance you are giving? 

 

The path of the righteous man is beset of all sides by the iniquities of the selfish and the tyranny of evil me. Blessed is he who, in the name of the charity and goodwill, shepherds the weak through the valley of darkness, for he is truly his brother’s keeper and the finder of lost children. And I will strike down upon thee with great vengeance and furious anger those who attempt to poison and destroy my brothers. And you will know my name is the Lord when I lay my vengeance upon thee.
