Just remembered these. Great when body parts start flying off you. Good for plastering too, @Onoff has some

Is that for Radon protection? They kind of all go together. How much insulation can you fit on ground floor. That is quite important. Almost certainly will, the walls will have a low U-Value, low SHC and probably leak air though them too. Lots of granite places here, and they are all hopeless when it comes to thermal efficiency.

Is that a cure for flu then? You not seen my girlfriend's make up have you. She looks like an Essex Girl after being strapped to Southend-on-Sea's pier for the winter.

The octogenarian Elsie McBane had a visit from her Presbyterian minister. As she was making some tea, he commented on her two Dachshunds , Molly and Mark. "They are very playful" he said, "but what do you do when Molly is in season?" "Och, that is simple", replied Elsie, "I just pop Molly up the stairs". "How does that solve the problem" asked the minister. To which Molly replied. "Have you ever seen a Dachshund try and walk upstairs with a hardon".

Do you have plans for it, sounds like a fun project.

If you see the term 'eco', it is probably not.

Here is what real scientists need to do when statistically testing samples. http://www.kayelaby.npl.co.uk/statistical_methods_for_the_treatment_of_experimental_data/6_1/6_1.html I suspect that the Chi Square is used for buildings. Chi Square compares expected results to real real results to see if there is a difference. So it all comes down to the expectations i.e. 1 in 10 houses will fail, will give you a different acceptable error compare to 1 in 8 failing. All bollocks really as even the test houses are only dodge to get a pass.

They used to offer grants, our old mate DamonHD used it, and that strange low carbon (Nofal or Naffle or whaterever it was) scheme to install his. That was deemed to complicated at the time too.

Or if we really want to know what is happening, then set this up right and it will give a decent probability P(k events in interval) = e-. k/k! Where: λ{\displaystyle \lambda } is the average number of events per interval e is the number 2.71828... k takes values 0, 1, 2, … k! = k × (k − 1) × (k − 2) × … Bugger, this sight does not seem to show symbols the same as my PC So just look up Poisson Distribution or time to failure and time between failure.

I think there was.

Or the drunk trying to walk along the white line in the middle of a very busy road, half the time he was one side, half the other. He should have been perfectly safe.

No it doesn't as they are independent events. That is like saying a football team cannot loose twice in a row

I would have thought that someone, somewhere, would have pointed out that there was already a large downward trend in prices and that the UK market would not materially affect that trend. Surely the better way would have been to tax the polluters more. We had a carbon trading/taxation scheme in place in Europe, but that fell apart though mismanagement/fraud. One of the problems is, especially in the UK, that if something fails first time around, it is never given a second chance. But you have to remember that I am not a lover of subsidies or any sort, when iti comes to business it is much better to punish severely than reward mildly.

Yes, but the government, well parliament, set the legislation, so it is their fault really.

Yes, and the installer I know that fitted one made an error. He had to start again. Then the installation had a lightening hit. So was bugger and I think abandoned in the end. It is the community hall in St. Just, so not exactly in the metropolis.

Can't think what, maybe £350 million a week on the NHS. Or just pay for a new sign for the side of the bus that says. 'We are robbing you'

Except you are personally punishing me, you rascal. I wonder if the real problem is simply that grid power is too cheap to create real inovation. And I say that paying 24p/kWh day rate and 9p/kWh night rate and have just paid my 'winter bill' when my E7 water cylinder was bust, so £260 for that quarter. Things are fixed now but when I calculate the total cost with meter rental and VAT, the unit rate is not often below 16p/kWh and that is using 80% night rate.

If the local DNO can handle it, then no. More is better. I often think the scaling is wrong. We try to self store enough energy to supply our needs on the days of little generation. But if we accept that we do need grid supplied power, then much small storage can be used. Taking data from Gridwatch for a random day in March, the peak demand was 20% higher than the mean, or 10 GW. The peak was in the evening and lasted 3 hours (5PM to 8PM). This is almost certainly caused by domestic use. So all that is needed is enough storage for that 30 GWh peak. Now keeping the maths simple, there are about 26 million houses, so that will be 1.1 kWh of storage per house.

Looks a lot better than my 1987 'professionally' fitted kitchen. When I had the house valued a few years back, the estate agent raved about it, saying how modern it was. But then, this is Cornwall.

Yes, they are lazy and the information could be useful to customers and suppliers. I think that is why there is the deemed export rate and the total generation rate. In an ideal world there would be no gain for anyone. The real problem is that the scheme was a pig's ear from the very beginning. But if you are exporting over 50%, then your PV system is too large (getting back on topic)

One problem with variable pricing is that the government has dictated that our energy bills need to be 'simpler', so less opportunity to have variable pricing. Not sure how this sits with the energy supply companies who probably want to use variable pricing. We have a secondary problem with our infrastructure insomuch as some supply companies are also generation companies. Generally this should not be a problem as it introduces an element of competition into the market, except it didn't as the main players have tended to stick to individual technologies i.e. EDF with Nuclear, British Gas with Gas, EON with Coal (but now RE and gas). Then you have to remember what happened in California in the early 2000s. California had 45GW of installed generation capacity and demand was about 28GW. But Enron realised that they could shut down supply to the state, sell it to a neighbouring state, then buy it back again at an increased price to the consumer. Our Contract for Difference would allow this to happen. Another, more serious problem with variable pricing is the the public will just not understand it. I occasionally chat to someone that supplies a data service to the power companies. He raves about 15 minute billing and how it will even out supply and demand. Sounds great, except no one plans their life to that degree. You only have to look at Gridwatch to see that we are all individuals, just like everyone else. This is rather going off thread here, but the point about the morals of self use is that most people on the FiTs scheme are getting paid to supply the grid with 50% of their generation. It is really not right to take that money and not supply the goods. If it was a business it would be prosecuted for fraud. But back to the main point. The first thing you need to do is an energy audit of your hourly consumption, then plot it against hourly irradiation. That will tell you what you can expect to happen. A hunt around on WeatherUnderground should find a local weather station with that data (you used tt be able to download it but the have changed the webpages so now not so easy).

You could call up a refrigerant technician and ask them for a quote, then when they say something silly, ask if they want to buy it off you. If they say yes, then you know , that they know, what is wrong with it and it is a tuppence ha'penny repair.
