Monday 6th April 2015 – I SMELL ALL OF COCONUT RIGHT NOW

Temperature in the verandah, 36°C – temperature in the home-made 12-volt immersion heater that I use as a dump load for the excess solar energy – 43°C. This can only mean one thing – a nice shower in the corner of the verandah specially set aside for the purpose.

The shower might only be a bucket and a jug to pour the water over me, but it’s a shower all the same and with the rainwater that I use (remember that there is no running water here) and the electricity that the sun generates for me, it’s all my own work.

There is as you know, a shower cubicle outside but it’ll be a couple of weeks before the water in the black plastic container on its roof has water hot enough to shower properly in that.

I knew that it would be like that today though. Last night it was cold, but one of these “warm colds”, with a steady breeze and totally clear sky. Not a cloud in the sky, millions of stars and a huge moon. And today, not a cloud in the sky either. I certainly made up today for the 9 consecutive days of miserable weather that we have just had.

As for the wind, we’ve had a steady wind all day. And to prove a point that I make regularly and which no-one else believes, this is another day in which the small 90-watt wind turbine outperformed the 400-watt wind turbine. In fact, the small wind turbine today produced more that twice as much energy as the larger one has produced since I reset the counter back in December last year – 4 months ago.

The reason for this is simple. They both have electrical generators in them, as you might expect. And in common with all electrical generators, they have magnets in them. And the bigger the generator, the bigger the magnet, so a more powerful wind speed is needed to overcome the resistance and start up the machine. That’s why the smaller wind turbine will start up and generate electricity in a much lower wind speed.

Apart from that, I’ve done nothing else except enjoy the last day of my Easter break. I’m back at work tomorrow.

Friday 28th November 2014 – BLIMMIN’ ‘ECK!

I installed the current lot of wind date instruments here about two and a half years ago, and of all of the wind energy that I’ve received since then, about 40% of it has come today.

It’s been a long time since I’ve seen wind quite like it, that’s for sure. I can’t see the little Marlec wind turbine from here, but I have a good view of the big old AIR403 wind turbine on the roof and that’s been going round like the clappers all day. I wish that I had it going like this every day.

And I’ve seen it for most of the day for, apart from having to go down and pay the boulangère, I’ve not been out of the house at all. I now have over 50kb of radio programme and with a Christmas recipe to come, that sets things up nicely for the show that we have to do and might even give me a head start for next year.

I’ve even made a startling discovery with this 3D programme with which I’ve been experimenting. There’s an add-on programme available on the internet to transfer shaping morphs from one item to another if they have been made on the same mesh-set. I’ve been fiddling with this for ages and never managed to make it work, probably because the objects that I have been trying haven’t been made on the same mesh-set.

But two of my favourite objects seem to have been so made, because in an idle moment over my lunchtime sandwich, I managed to transfer the morphs over from one to the other. That is certainly progress and I’m impressed with this. I just wish that I could do this with the other objects.

Saturday 29th March 2014 – JUST HOW UNLUCKY CAN YOU BE?

Jerome Brunet has the ball about 15 yards out and whacks the ball goalwards with everything that he has got. It hits the knee of a defender, cannons right out of the area and back all the way over the halfway line to where a lone Beauregard l’Eveque forward is standing. And he has the simplest of tasks with a one-on-one with Michael, while everyone in the stadium looks on, open-mouthed.

Back in the early 70s I once saw Albert Kinsey, playing for Crewe Alexandra, hit the bar with such force that the rebound cleared the halfway line before it bounced, but I’ve never seen anything like this.

So FC Pionsat St Hilaire lost again, 5-3 this time, to this goal and two of the most controversial offside decisions that I have ever seen, each one of which resulted in a Beauregard goal. And Pionsat should have had this team dead and buried. Hit the bar, hit the post twice, kicked off the line three times, and in the dying minutes they had 6 consecutive corners to add to the 25 that they had had during the rest of the match. But to lose a game in this fashion leaves a nasty taste in the mouth.

Add to that the fact that Michael bravely took his place in goal after his bad injury two weeks ago, but lasted just 45 minutes. Young Frédéric took ovee for the second half and looked the part, but he let two goals in and you really can’t do much about that. Everyone was doing his best today.

But it does have to be said – that breakaway goal, no matter how unlucky, wouldn’t have been scored had Pionsat’s defence been concentrating. Those two offsides – how many times do I have to spell it out – you don’t hang around with your hand up waiting for the referee’s whistle, no matter how clear-cut it might be. You play the ball and let the whistle take care of itself.

The fourth goal – the defence being out of place when the team loses possession and the midfield slowly ambling back instead of having any sense of urgency at all. Consequently the defence is caught short-handed.

And the fifth goal – Pionsat messing about in defence again – failing to clear the ball upfield or out for a throw-in but showing off on the edge of the penalty area and losing possession.

It’s all simple schoolboy errors, this is, and it’s been the same ever since I’ve been following the club, and probably before as well. The problem is that there is no leadership out there in the team – no-one who can take command.

So apart from that, having had a day off yesterday, I worked today. Until 12;00 I was working on the laptop – not on the website but writing the notes for the rock music programmes that we do on Radio Anglais.

Later, I went out and dug over another raised bed. This is the one where the shuttering has collapsed and so I used those red bricks that I was telling you about. However it hasn’t worked – that isn’t going to be very successful unfortunately as the bricks are too low and so I can’t dig them in properly. In fact it looks something of a mess. I shall need to think again.

I did manage a bit of work on the website once I had finished the raised bed. It is Saturday after all and there’s no point in killing myself by starting on another one.

And we had another day of high winds. More wind energy today than we have had in the last three or four weeks combined. I wish that it was like this every day.

Tuesday 24th December 2013 – TOTALLY ASTONISHING!

Yes, I should say so. The wind here has been such today that I’ve had more wind energy in the last 24 hours than I’ve had in the preceding 12 months. According to the anenometer on the barn, we had gusts of up to 52mph. I was in the barn as a little of this was going on, a quick glance at the wattmeter attached to the ageing 400-watt Air 403 that I bought from Southwest Wind Power in Flagstaff, Arizona in 2002 was showing that at that particular moment I was receiving 280.3 watts of power and I have never before seen anything even approaching that amount of power.

And even as I type, I can hear the hollow tube of the turbine mount whining away, which means that the wind turbine is still churning it out. All in all I’m overwhelmed with this and I do wish that I could have this amount of wind every day.

shelving unit upstairs lean-to les guis virlet puy de dome franceMeanwhile, back at the ranch, the shelving unit is finished – or, at least, it’s finished as far as it will be for the next few days and I’ll add the doors and siding in due course.

It took me about 4 hours to finish it off and to screw it down, and the hardest job was to set it all in tension. It’s not just a floppy old wobbly shelf unit but something quite structural.

The shelving planks are a little warped but firstly, it’s cheap concrete shuttering that I buy at Brico Depot. Rough and ready, very solid, very thick, and very cheap. And secondly, of course, it’ll straighten itself out when it has some weight on it. I don’t mind it being like this at all – it’s not as if it’s for the inside of the house, of course.

When I finished it, I started to load it up, but called a halt for lunch – rather later than usual but I was enjoying myself.

After lunch and a brief siesta (I really don’t know what’s up with me these days) I went round to Liz and Terry’s with their Christmas presents, and they very kindly fed me and also loaded me up with a pile of goodies too, more of which tomorrow.

And now I’m back here. All of the alarms are switched off and I don’t intend to be doing anything for the foreseeable future. After the year that I’ve just had, I deserve a really long break.

Friday 19th October 2012 – THE HURRICANE …

… finally calmed down during late afternoon.

But not before several really impressive records were set. We didn’t quite manage the maximum wind-speed – the 66.7mph gust from May is safe for another while yet- but everything else was historic.

So much so that the Air 403 wind turbine on the roof of the barn generated more electricity today that in the rest of the 15 months that it’s been there.

The Rutland WG901 on the house surpassed the previous record and showed me the magic result on the timer
“Time since I took the last reading – 25 hours and 16 minutes”
“Wind time since last reading – “25 hours and 16 seconds”.

As well as that, the temperature here in the attic is now back up to the 20s – and I should think so too. I was freezing the other night.

So anyway, after the usual messing around on the computer I went outside to rectify the damage.

I picked up the kindling bins and the kindling and reorganised them (I don’t know why I bothered though – they blew over again) and picked up all of the stuff that had been propped against the end of the barn (and that blew back down twice more)

Major work though was with the Air 403 wind turbine fastened to the fence.

The screws have given way under the fierce battering that they took from the wind and the whole affair was blowing around like crazy. Screws clearly don’t work.

As I didn’t have any bolts long enough, you can see the benefits of having lengths of stud iron (or threaded rod as it’s called these days) lying around. I cut a few lengths of that and made up some bolts, and now it’s all properly bolted together and I hope that that won’t move again.

With no bread and still no boulangère I went into Pionsat to find out why she doesn’t love me any more, and I soon found out, much to my dismay.

The boulangerie is closed.

According to the notice on the door, it’s closed “until further notice” following an accident on the premises involving the oven. That’s upset my plans and no mistake. I shall have to think again about this.

Back home I finished off emptying the back half of the hard-standing. I need to buy some weedkiller to deal with the weeds on there, and on Monday I’ll start digging out the soil that has collapsed.

This is going to be a very long job.

Thursday 18th October 2012 – IT’S BEEN BLOWING …

… a right old gale here today.

I’m having a world-record day for wind, that’s for sure. Even the wind turbine that is anchored to a plank and stuck up on a fence has recorded about 5 minutes of wind time, and that’s astonishing.

As for the others, the one on the barn has had over 17 hours and the one on the house has had over 21 hours.

And with the wind gusting to over 45mph the amount of energy created is phenomenal.

So much so that in the depths of darkest night I’ve actually seen the ammeters run backwards for the first time ever during the hours of darkness. 13.1 volts on the battery bank in the barn is unheard-of at 22:00.

Mind you, its playing havoc with everything else.

The bins with kindling in have blown over twice. I picked them up the first time but there’s no point in doing that again because they’ll just come down again.

It’s not raining, and not likely to either with this wind, and so they aren’t risking anything. Mind you my money is on a torrential rainstorm as soon as the winds drop.

I did mention yesterday that the weather is turning earlier than normal this year. I recall these windy conditions usually occurring in mid-November – in fact trying to watch a football match at St Avit back in 2008 one Sunday afternoon.

Yes, winter is definitely starting earlier this year.

I’ve also emptied half of the hard-standing now – I just need to clean out where the banks have collapsed and then I can do the next part of the job.

As for the bank itself, I’ve decided that I’ll go half-high with breeze blocks and then lay wire netting over the other half, pour cement over it so that it forms a kind-of ferro-cement and then lay stones over the top.

It should look quite pretty, but I’ve no idea how it will work out.

Tuesday 13th March 2012 – A FEW MORE …

… records tumbled today.

We had the glorious weather again, so much so that the water that is heated by the surplus energy from the solar panels, the “dump load”, was heated to such an extent that it went off the end of the temperature gauge – ie over 70°C.

That’s the first time this year.

The water in the solar-heated tank (a black plastic box with a glass lid) reached 26.5°C and that’s the highest so far (but still a far cry from the 45°C of midsummer) and if it hadn’t have been so windy, I would have put some of the water out of the dump load into the solar-heated tank to bring the temperature up to about 38°C and I would have had the first solar shower of the year.

But it was far too windy – I would have died of exposure I reckon, and the fact that showering outside in the all-together is the way that it’s done around here, it would have been indecent exposure too.

Talking of the wind, it’s died down now, after the last few days, but once again I had more wind energy created today than the cumulative amount of wind since I installed the power meters 2 weeks or so ago.

Mind you, I don’t think that we will have that again tomorrow.

But here’s an interesting and little-known fact, one that I can now prove. And that is that you can often have more power from a low-powered wind turbine than you can from a high-powered one.

Confused?

Well, let me explain.

Most electric motors, and wind turbines are no exception, have magnets in them and these operate the coils of the motor. Of course, the bigger and more powerful the motor, the bigger and more resistant are the magnets. And so you need more force to overcome the resistance in the magnets.

When you have a low-powered wind it will overcome the resistance in the magnets in a low-powered motor, and make the motor turn. However, there will not be enough force in this low-powered wind to overcome the resistance in a big magnet in a high-powered motor so that this motor won’t turn.

And there I was today, watching the little Rutland 90-watt wind turbine quite happily ticking over and giving me 10 – or 15 watts for much of the day while the big 400-watt wind turbine was doing nothing at all.

And then, all of a sudden there would be a stronger gust of wind and the big Air 403 wind turbine would start to turn, and once it had built up steam it would be there with 50 watts, or 80 watts, or even 113 watts on one occasion, while the smaller wind turbine was giving out 30 or 40 watts.

But be that as it may, the smaller wind turbine chucked out in total three times as much energy as the larger one over the 24-hour period under review. And it’s done that consistently over the last few years.

There are lessons to be learnt here of course – namely a collection of low-powered turbines will do more good than one big one over a continuous period, especially in a place like this.

Monday 12th March 2012 – WHAT AN EXCITING DAY!

The first exciting thing that happened was me lying wide awake in bed for ages thinking that I may as well get up – and finding when I did so that it was all of 07:45 – a good half-hour before the alarm goes off.

And not only that – with having had the fire on up here last night to cook a pizza, it was 16.6°C in here too, and it actually felt warm as well.

So having had breakfast and another load of coffee I did a pile of stuff on the computer. And then it was off outside to survey the house and barn – something that, quite surprisingly, I have never done.

It was not only glorious sunshine but a really strong wind and once more the wind energy today exceeded the cumulative total since I installed the power meter. And all of that was totally exciting as well.

Knocking off at 18:30 I discovered that the water in the dump load was heated to over 68.5°C and that’s a record this year. I had a gorgeous hot wash and shave with the water at that temperature and that made me feel so much better

At the Anglo-French group tonight we had two new attendees, Isobel from the Comcom at Marcillat en Combraille and her friend. We all had a really good night down there in St Gervais d’Auvergne.

And on the way home, the stars are the brightest that I have seen for a while. There are thousands of them out there, and Jupiter and Venus are wonderful. I can’t see Uranus from here though.

Back here, the water in the dump load was still 61°C and so I rounded the evening off by doing the washing-up with it, saving the gas supply for tonight.

So you can see what I mean about “exciting”, can’t you.

But in really depressing news, it’s three years tonight that Liz left us all. Time travels so fast these days but it can’t dim the lights.

Sunday 11th March 2012 – CONTINUING ON …

… with the saga of weird football matches, I went to Terjat this afternoon to watch AS Terjat play a team from Montlucon – Bien Assis I think – seeing as how there was no Pionsat team in action this afternoon.

The trainer for Terjat, with whom I struck up some kind of conversation last time I was there and which carried on this afternoon, told me that in the league tables Turgid were well ahead of their opponents, and that they needed to win (which everyone was expecting) to keep up some kind of reasonable pretensions for promotion.

He was right about the “well ahead of their opponents” bit, because a more one-sided game you would not wish to see.

However from the first attack of the game one of the Bien Assis forwards had a weak shot on goal, well covered by the keeper and which would have been comfortably saved had the ball not taken a wicked deflection off the needlessly-outstretched foot of a Turgid defender and rolled into the far corner of the net.

For the remaining 89 minutes AS Terjat were camped in the opposition half with their keeper being merely an interested spectator.

And the final score?

Yes, you guessed it. 1-0 for Bien Assis.

As an aside, the Turgid keeper had one of the most powerful kicks I have ever seen and his clearances upfield were outpacing his attackers every time. And one of the Turgid central defenders was the best header of the ball that I have ever seen at this level of football.

In fact this game was quite a decent match for aerial prowess. I’ve not seen another match quite like this one for that kind of thing.

But the referee came out onto the field of play having left his cards in the dressing room.

At least that’s the only reason I can think of as to how we managed to reach the end of 90 minutes of this match without a single card being shown, despite the kind of goings-on that we had during the game.

“Hard-fought” is probably quite an apt description.

In other news, I had something of a lie-in today. In fact, 11:29 was when I crawled out of my stinking pit. About time I had a good lie-in.

We are also having a record day for wind power. I’ve had the power meter connected up for about 10 days or so, and we’ve had more wind today than the cumulative figure over the other 9 days.

It really is quite impressive.

Thursday 9th December 2010 – I WAS RIGHT ABOUT THE WEATHER.


heavy snowfall les guis virlet puy de dome franceI woke up this morning … "DAH DAH DAH DAH DAH " – ed …to -2°C and a covering of snow everywhere.

And perishing cold it was too. It snookered my plans of digging up the chicory and blanching it – I needed a hammer and chisel to get into the soil.

So instead, after cutting a pile of wood, I started to wire up the wind turbine on the barn to some batteries I had lying around. I may as well try to make use of some of the wind that we might have.

But that was a perishing cold job too and by the time that lunch came around and I still hadn’t finished and I was frozen to the marrow I abandoned that idea too.

After lunch I made a start on moving some of the old slate that is in the bedroom. And after about 50 bucketfuls up and down stairs you can just about notice the difference. I had no idea how much there is in that room. I’ll be here until next Christmas trying to shift it all.

But at least I’ve shifted enough so that I can get the next load of insulation onto the wall. I can do that tomorrow if we still have sub-arctic temperatures.
