B&Q Wind turbines

I imagine that the detractors simply used one of their usual soundbites, the one about wind farms only producing 30% of their output. I accept that some of the detractors may only be ignorant about what capacity factor is, but I doubt if they all are only ignorant.

The article is very clear that the site only produced "around 90% of our forecast annual output." What it doesn't give is what percentage of the rated output the "forecast annual output" is.

shows that for the year the capacity factor was 28.9% which implies a forecast of 32%. This is more or less the norm for windfarms. This 30%(ish) of rated capacity is the important number not the rated or installed figure.

I wouldn't buy one from B&Q, I'm sorry if I gave that impression.

Prices don't rise often, the things we send are different sizes and weights meaning that they need variables even though most will go into a pillar box. I'm not saying that what we would do would work for everyone but it works for us. With only a few smaller value stamps (10, 2 and 1p) I get by very nicely.

Fixed visiting times? My life doesn't run according to clockwork :-)

Depreciation is irrelevant to us, we run a car until it dies. I've never done the sums but convenience, on the prettey rare occasions we use the car, is priceless. It runs not more than 5,000 pa, usually more like 3,000.

Indeed, we have many. I've never yet seen a mini cab which keeps to speed limits, obeys traffic lights and has good lane discipline.

Leeds is full of cars which seem to be immune from the law by dint of displaying red plates at the back.

Well, that's exactly what I expected.

Yours might not but the NHS does. B-)

So do I, though of the four cars I have owned in the last 20+ years 50% have been killed rather than die. Of the other 50% one is the current motor which I hope to still be driving with close to 200,000 miles on the clock in ten years time.

Depreciation still need to be accounted for as you need the capital lump via some means to buy the replacement.

That is because the latter is a not particularly important figure. If they bid to supply an annual output then they will have had to purchase the missing 10% of that from the market. They have not had to purchase 70% of the rated output.

This is the way electricity works. Plants are generally not be designed or expected to operate at full output all year. This may be for engineering reasons, such as the supply of water to a turbine, or management reasons, such as a decision not to sell at particular times.

I can see why the antis harp on about the difference between a theoretical figure assuming that a wind farm generated at 100% of rated output all year. However, the same analysis of an open cycle gas turbine plant used only at peaks would show an even lower capacity factor.

Can't you do that online yet?

You can now, but if you want your local PO to survive I wouldn't recomend it.

I've not experienced that since 1960 when visitors queued at the ward doors with their tickets and a bell was rung at the end of visiting time.

During Spouse's stay I was welcomed by the staff because I was relieving them of personal care. I also took in his meals and drinks. I went in for five or six hours during the day and two or three in the evening. I asked if it were acceptable and was told that it was no problem. That way I could also be involved in the physiotherapist's, pain team's and consultant's visits.

Well, we don't think so. We don't take depreciation into account when we buy clothes, white goods or, well, anything. We've only had one car killed, that was in 1971.

Yes and it's very easy.

I also obtained a replacement driving licence by phone. No hassle, a courteous Welshman who had all my details (more than I did!).

I haven't written a cheque since 2004. Before that, it was 2001.

You're having a laugh. When my latest was born, I was chucked out an hour or two later after "visiting time", much to my wife's disgust. She hadn't even wanted it in hospital. The one before was born at home, which was much better. An hour after the baby is born, all the staff have b*ggered off, leaving you in your own bed without so much as a taxi ride to bother with. In hospital she wasn't even allowed to leave until the following afternoon, because they couldn't find a doctor to sign her out.

I realised that when Spouse pointed it out to me, I promised I'd not be so thoughtless in future.

We, the Fishers, use the local post office a lot, mostly for sending parcels and packets which won't go into the pillar box. It would be more than inconvenient to lose it for that reason alone.

The message from mogga contains these words:

Yes, but not if you've only just bought the car as they send the disc to the address on the V5 - which won't have changed yet.

Not at all. They were very strict. But it was a long time ago.

I couldn't agree more, I had one at home but I was told that the next one had to be born in hospital and in those days I didn't stand up to Authority.

In 1960 I was in for twelve days.

In 1968 I was in for about three.

? We didn't need doctors to do that ...

How things have changed, not always for the better. It's a particular bee in my bonnet, modern obstetrics..

This has been covered extensively before with some useful facts and figers see

to start from about post 60 but to sum up the advertising blurb from Windsave is wildly optimistic and possibly even deceitful. you would need to average over 6ms windspeed for most of the year for this to be even remotely financially worthwhile.

Only extremely exposed coastal or hill top sites would be able to achieve this, fine if like me you live in a ex lighthouse-radar station overlooking the north sea

, but on the side of a urban house below ridge height as in the Windsave picture it would never even repay its purchase price over 12 years.

You didn't.

However, it is worth repeating what they say on their web site, on the WS-1000 page from the Technical menu, "The Windsave System is ideal to install at all locations that benefit from good exposure to the wind." If the knockers are to be believed no such statement is made by the promoters of this device.

I suspect that Swift and Proven make similar statements.

Well, they have to. That's their get-out clause when it fails to deliver. Most consumers will not understand that 'good exposure' is difficult to attain with most houses.
