Screwy-looking wind turbine makes little noise and a big claim

I had friends staying here the past few days from the Arķege region of France. They said there are disputes in their region where one village is offered large amounts of money to permit a wind farm in their immediate area (to which they have no objection) which will be visible from other villages which have not been offered similar inducements. The grounds for objection are the usual ones of noise, visual despoilment etc etc., but these all suddenly disappear when the money offered to the first village is reduced or cancelled completely, and offered to the objecting village. At which point, however, the first village suddenly finds that after all it has objections, such as noise, visual despoilment....and so it goes on.

Hellsbrink has not been around for something like six months now.

There's any number of 'novel' wind turbines being proposed, all claiming to be super-efficient.

We'll know when a worthwhile design is actually achieved, because it will be economic to install without jumping on the subsidy gravy-train.

yep, but some of them look really impressive (=promising), like the BAT:



Altaeros Energies - The Buoyant Airborne Turbine

- but I'm still dreaming of a small one on my roof to heat the water...

I like the alternatives probes illustrated for us - but are they as efficient at bird mincing than the ones currently blighting the landscape? We need to be told!

Recently drove Hwy 402 from London to Sarnia. Saw hundreds of the wretched things either complete or under construction. No power lines though...

It takes several years of wind turbine output just to pay for the energy used in manufacture, transport and construction.

One element of wind power generation I find disagreeable is the toll it takes on birdlife. The California Condor was rescued from extinction through an enormous effort, and the cause was celebrated among the eco-warriors. Today, there is little objection from that crowd at the prospect of sacrificing that species to the vagaries of wind power.

I've been looking after a medium size research turbine since 1994 and if the stories of bird kill were true I'd be up to my neck by now. Biggest problem I have with birds is stopping the crows nesting in the damn thing!
We have a hobby, small falcon type thing that sits on the blades when the thing is stopped, so I'm not convinced that birds are as stupid as people make out.
Having said that one of the biggest bird killers are High tension lines. Whether it's green energy, coal or nuclear they still get zapped!

He was most prolific, as was the thread starter Stuckgear, also gone and Minderbinder as well. Was it something we said ? Perhaps it was too much hot air

Neither proponent nor opponent

As a professional engineer in the power industry (but by no means a generation specialist), a few points...

1. Wind turbine manufacture may contribute to carbon emissions, but so too does the manufacture and construction of conventional plant.
2. Wind turbine efficiency of 30% is not atypical...thermal plant has traditionally been in the 30% area, although combined cycle gas turbines push that up towards 50%.
3. When the wind doesn't blow, turbines don't generate. However, the wind is always blowing somewhere. Therefore work is now underway to link wind generation 'areas' with a supergrid. This allows available wind generation to be shared where needed. It also offsets the need to provide conventional backup.
4. Offshore sites see more wind, more often.

I don't find turbines that offensive, and here in Northern Ireland, they contribute significantly to our demand. Personally, I don't think they are the whole answer. As in many decisions, the right answer is somewhere in the middle. We need a mix of base-load nuclear for stability and self-reliance, gas for its relative ease of construction and low cost, and renewables to begin denting the carbon issue.

No No NO!! There is no middle ground you centralist extremist you.

I believe that hydro works quite well in certain locations, with the water being pumped back up to the 'header tank' when there is reduced demand for electricity.

I expect that the electricity to pump the water has to be drawn from another source (or, maybe the generators are multi-channel?) otherwise with the inevitable inefficiencies would require more power to raise the water than could be generated when falling - even a slower rise would result in the same work done over time - and you can't get owt for nowt energywise.

I thought that there was also one in Scotland, but I've filed to find it.

Here's the one in Wales:- Dinorwig Power Station - Wikipedia, the free encyclopedia

I think the Scottish one is on Ben Cruachan, pumping water up and down from Loch Awe.

Visit Cruachan: About Us

Apparently the first high head pump storage scheme in the world.
I suspect both it and Dinorwig will be busy during the current Kev ball Hostilities.

There's another at Ffestiniog, which was actually the first one built in The U.K., 360MW.

And not just condors.

That huge Solar array on the Calif / Nevada border trampled over huge number of species include the rare tortoise that had held up other development but didn't hold up the Solar array, which now kills flying birds.

The Greenies have one rule for them and one rule for everyone else when it comes to development, especially when it comes to damaging the environment to install Wind Turbines and ruin the views.

High tension wires also kill lots of birds, especially bigger birds like Swans etc.

Actually studying the grid watch supplied link is interesting, what is more interesting is the French one.

The frogs where generating over 20% excess power of good wholesome base load to the Poms, krauts, and anyone else they could. Over 100% of their load was Nuclear. About 15% hydro.
