Windsave - a PPS

I don't know what the bill for Tony's brand new nuclear power stations is likely to be, but I'd guess that it's going to be quite a few billion (or maybe more).
So what if instead every house got a windmill?

The CIA World Fact book reports that UK electricity consumption in 2003 was 346,100 GWh. So that's about 39.5GW of generating power. If everyone in the country has a windmill then that'd be 60GW of production.
Now I'm not saying that everyone should have a windmill, nor should we expect them to work 24x7 all year round. But if everyone in the country had their own capability to produce 1KW then we'd certainly not need any new nuclear plants (and therefore no environmental arguments to overcome). With combined heat/power, and all sorts of other personal electricity generation, maybe small is the new nuclear. And with a Windsave only costing £1500 or so, even 60m of those would be cheaper than all those nuclear stations!

I'm English - shouldn't it have been Concord?

Murphy's law 2 (Maguire's law)

A client went live yesterday with a new version (1.1.5) of their software. Whilst 1.1.3 and 1.1.4 had been tested, they had never gone live. This morning, urgent phone calls - "we cannot change items in the database, 3 users have got problems".

After a hours frenetic activity it turns out there was a bug in 1.1.2 (installed nearly 3 months ago), that had lain in wait for us.

Honestly, what are the chances of a 3 month old bug being found within 1 hour by three different people the day after another new version goes in?

Maguire's law - he said Murphy was an optimist! I'm off to buy a lottery ticket, i've got to win something with that luck.

Murphy's law 1

A couple of weeks ago we got a ceiling fan and light for the bedroom. We'd had these fans in the hotel on holiday recently and thought them really good. It took a few hours (finding a joist under the boarded attic floor was entertaining!), but the job was done, and done well.

I hoicked up the air conditioner to my study/bedroom too, so that I can cool down all the computers running in there.

And finally, in preparation for warmer nights, we put the thinner duvet on.

Weather since then? Cold, breezy and wet. Lovely.
