Friday 26th July 2013 – WE HAD A COUPLE …

… of rainstorms today

Not much of a surprise though because it’s been threatening for a day or so.

The first one woke me up, again before the alarm went off, but then that’s no surprise seeing as how I was away with the fairies for a while yesterday afternoon.

So after breakfast I sorted out a few papers that I needed for the notaire and off I went.

It takes an hour and five minutes to walk there, as I now know for I timed it.

Yes, off I went on foot. I seem to have much more exercise when I’m here in Brussels than when I’m at home in France. When I’m out I do a lot of walking.

Bit of a shame that the walkman went flat after just 400 metres but then you can’t have everything.

The notaire didn’t come up with anything that was unexpected – well, yes she did, but what I mean is that nothing in Belgium is unexpected, if you see what I mean – it’s all par for the course.

So I left the building, straight into another rainstorm, and walked into town.

Belgian drivers are the worst in the world, and so it’s no surprise to see that the coppers have no room to be complacent.

With driving like this from the police farce, no wonder that they can’t recognise poor driving whenever they see it and so the standards go down and down.

This column, extremely controversial in its day, was designed by Joseph Poelaert and erected in the 1850s.

It is meant to commemorate the people who “ont fixé les destinées nouvelles du pays, après la fondation de son indépendance” – “gave the new country its new direction and future after independence”.

47 metres high, there is a spiral staircase of 193 steps inside and in the olden days it was possible to climb to the top.

Unfortunately, that’s not possible these days. Like much of Belgian infrastructure, it’s in poor condition. And it was badly-damaged by Hurricane Cyril on 18th January 2007.

One unidentified Belgian soldier was taken from each of the battlefields on which the Belgian Army fought in World War I and a blinded Belgian veteran made the choice of which one was to be interred here.

He was laid to rest here on 11th November 1922 and an eternal flame was lit.

After a mega-ramble I ended up at Elak, one of my favourite shops in Brussels. It’s an electronics shop and I buy my 12-volt LED warning lights and 12-volt piazzo buzzers from there.

I’m running a little low on the aforementioned and so I need to build up my stocks. No red lights in stock, and the blue ones are flaming extortionate, so I stocked up on a few green and yellow, and a couple of buzzers.

I’ve also found (well, remembered) a shop, Pêle-Mêle, that buys second-hand books, CDs, computer equipment and that sort of stuff and so I can move on a pile of Marianne’s stuff without too much effort and that will make even more room here.

I caught the bus back here, and once more crashed out for a few hours, but this isn’t doing any good. I’m going to have to start focusing myself so much better on what I need to be doing.

In other news, I was listening to one of the new CDs that I had bought the other day just before leaving. Warren Zevon’s superb Stand In The Fire.

A magnificent album, it really is, and it features, apart from “Excitable Boy”, “Werewolves of London” and “Send Lawyers, Guns and Money” (which will be my theme song for Canada-2013 of course) – to name just a selection of good music, a magnificent mickey-take of “Sweet Home Alabama”, entitled “Play It All Night Long”.

When I was in North Carolina in 2005 I remembered these Classic Rock radio stations that played nothing but “Hotel California”, “Free Bird”, “Bohemian Rhapsody” and, of course, “Sweet Home Alabama” non-stop. I wish that I had had a copy of “Play It All Night” back then.

Anyway I edited the relevant page of the journey to include the lyrics of the chorus. They were really appropriate for the journey through North Carolina.

Saturday 19th November 2011 – WELL, I’M A BIT ….

… disappointed today.

In the last 24 hours we’ve had 21 hours of recorded wind and the turbine has been going round like ye veritable clappers.

And do you know what?

There’s not even one watt recorded on the dial.

A quick check revealed that there’s no current reaching the battery bank. That’s sad.

I checked the two joints to the wind turbine and they seem to be working fine – I connected up a little piazo buzzer and that was ringing like Big Ben – and so it’s either going to be the final joint or else there’s a break in the cable somewhere.

That’s going to be a job for the multimeter on Monday morning

But it was certainly encouraging to see how the thing was going around today. And of course, all the time that it was going round, the big AIR 403 wind turbine didn’t move a muscle. It proves the point that I’ve been arguing with everyone for years that a small turbine can quite often produce more energy than a large one.

Why this is so is quite simple.

Feel the weight of the motors. The heavier a motor is, more powerful it is (generally speaking, of course. There are always exceptions). And the weight is made up of the copper coil and the magnet in the motor (it’s not this simple, but for the purpose of this discussion we’ll leave it here).

So the more powerful the motor, the bigger the magnet and the more magnetic resistance it contains. And so the more wind that you need to overcome the magnetic resistance. A less-powerful wind turbine will have less magnetic resistance and so it will need less wind to make it work. In low-wind situations (which is what I generally have here) two smaller wind turbines will pump out more power than one large one.

This afternoon I went to St Eloy-les-Mines where I spent next-to-nothing again but I did do a mega-wash at the launderette. That’s cheered me up. All clean clothes again. All I need to do is to find a way of getting me nice and clean as well, and then I can have nice new bedding. I shall work on that.

It was the Annual General Meeting of Pionsat Patrimoine this afternoon and interesting as it might be, I still can’t deal with the egos and the people who take 100 words to say either yes or no – and then say it 10 times over.

No footy tonight at Pionsat – Gerzat couldn’t raise a team to play the 2nd XI. But there was a game on at Marcillat, and that provided me with the biggest laugh that I have had for quite a while.

A goalkeeper and a forward went for a 50-50 ball and the keeper came off worse. It was a foul but a genuine attempt to play a loose ball with no malice whatsoever. The ref,in his wisdom, shows the Gannat forward a yellow card.

Outrage from the Gannat bench – and quite rightly so if you ask me. “We have to protect the goalkeepers” shouted the ref.

30 seconds later we have an almost-identical situation and this time it’s the forward who comes off worse And no yellow card. And in the silence of the still night up on the plateau where Marcillat play, the  Gannat trainer bellows out (and I mean Bellows Out- he could be heard back in Gannat I reckon) “and you have to protect the forwards too!”

At that remark, the whole ground collapses in laughter, except for the ref who clearly has no sense of humour whatever and goes over to talk to the trainer

Well, I wasn’t the only one who thought it funny. And doesn’t that makes a change for round here?

Wednesday 14th July 2010 – Today will go down in history!

I’ve finally fitted the most important piece in the jigsaw of my electrical system here (the wind turbine notwithstanding) and that it the electric water-heating mechanism.

How my system works at the moment is that there are two banks each of three solar panels and each bank is connected to the batteries via a charge controller. The two controllers are set up differently so that one cuts of when the batteries reach 14.1 volts and the other one cuts out when the batteries reach 14.15 volts. They both cut back in when the battery level drops to 13.4 volts or so. This avoids any overcharging of the batteries.

You can tell when the batteries are fully charged by the difference in solar charge received by each of the banks. If there’s a substantial difference then that will be because the one set at a lower charge will have cut out, just leaving the second one running. And if I have the fridge working then sometimes the difference can be substantial. On the 8th July for example one bank recorded 37.7 amp-hours whereas the other recorded 157.3 amp-hours, almost 2 kilowatt-hours of charge.

You can see therefore from this that there can be times when an enormous amount of solar energy is totally wasted. So what you can do is to rig up a system whereby once the batteries are fully-charged then instead of the system shutting down, all of the unwanted power is diverted into some kind of “dump load”.

dump load 12 volt home made immersion heater les guis virlet puy de dome franceI’ve had plans for this for ages and a while ago I bought some 12-volt water heater elements. And today, even though it’s been a Bank Holiday and I don’t normally work, I’ve rigged up an old galvanised 50-litre ash can as a kind of ad-hoc immersion heater.

It’s going to have to be developed further of course. Electric elements floating around on wooden pontoons in open-topped galvanised ash cans full of water right close to the main access in the house is a recipe for some kind of disaster sooner or later and one of the reasons why I’ve been holding off from fitting this dump load is because I’ve been looking for some kind of more substantial and correct recipient but in the absence of anything more positive I can’t be waiting for ever. The piazzo buzzer on there by the way is to let me know when the circuit opens up

vauxhall cavalier car clock renault clio electric timer dump load les guis virlet puy de dome franceThe proof of the pudding is of course in the eating and now that this system is wired in I can put a 12-volt clock in line to tell me how long the circuit is open.

And so while the clock on the right (from a Renault Clio by the way) keeps the time, the one on the left (from a Vauxhall Cavalier) tells me how long I’ve been heating the water.

1h20 (it was about 1h35 by the time it finished) may not seem a lot to anybody and the water didn’t get all that hot but on day one with 50 litres of water in what is effectively a large open bucket – that has to be progress. Just imagine that in a 50-litre sealed tank with loads of insulation around it.

And I had a visitor this afternoon – a guy who I met the other day and wanted to discuss solar panels and wind turbines. He was here for about three hours and we had quite a lengthy chat.

And that’s not the only visitor I had today either. The windows up here are wide open and there’s this lovely gale blowing right through here, and it’s just blown this huge, enormous green thing that looks like a cricket right into the attic. We had quite a chase around the place and eventually I caught him in a plastic box and threw him back outside.
