Unless used for cooling. (I may have missed something posted up earlier about this, the beach wear is a distraction).

They nearly did. https://energysavingtrust.org.uk/a-brief-history-of-the-electric-car/ Probably failed because no one wanted to by a car from a yamyam called Parker. Should have stuck to pens and driving Lady Penelope about, 'My Lady'.

Is the thumping caused by a lady from Ealing. Maybe she don't have too many feelings. If she laid on her back, observed the crack. She might fix it by sealing.

Not that crazy. No worse than a green roof in reality.

More seriously, have I remembered how to calculate PSI near enough correctly. If so, it is dead easy to set up a spreadsheet and calculate. I think the ∆T will be the inside air temperature, minus the median value of the ground and the outside air temperature for the perimeter.

Not adults until they pay the bills and have to put right their own mess from their savings.

Yes, and.

There is, but it is based on mass flow rates. Luckily in the case if water, mass and volume are equal mathematically. They have in here, frequently.

The electrical generation industry started, in earnest, planning and building windfarms 30 years ago. It takes the first decade to get though planning, then it was relatively small scale stuff employed, then the moratorium happened that forced the wind industry to develope techniques to cost effectively install at sea. Last year wind power generated more electricity than gas (I think). Now wind is the cheapest form of electrical generation, whether the fossil fuel industry likes it or not. Increasing solar generation is going to be the next target for growth, not nuclear, tidal or biomass, the economics don't stack up for them. Just looked up when Delabole Windfarm was built. 1991. It was proposed in 1989. So 2 years to get though planning and constructed. That was 32 years ago. What the (expletive deleted) is wrong with us in this country, we have really lost the plot on planning and infrastructure.

Not where I was, the smaller button how fallen off, leaving a white lever will a ball on the end, I was too scared to touch it, I saw the mess on the seat rim. One can never trust anything that bleeds for a week and does not die.

No. You can calculate, pretty accurately, how warm a wall will get from sunlight by using PVGIS. A wall is just like anything else left in the sun, it gets warmer, this reduces heat losses, or may actually increase room temperature. It all depends on the make up of the wall, the exposed area and orientation, hence my NW and SW corner example. There is also cases where you want rooms at different temperatures. A kitchen, used solely as a kitchen, probably needs a lower base temperature, than a living room, which may, in turn be higher than a bedroom. Bathrooms probably have the highest temperature due to usage (lots of 40°C water, and the need to be kept dry after use. Some of that heat, heat is the old term for energy, will travel though the walls into the adjoining area i.e. a bedroom or landing. Changing the spacing of the UFH pipework for the same delivery temperature and flow from the ASHP/Boiler allows for different room temperatures and losses/gains. This is why a room by room heat lose calculation is done, you can take into account the usage and the seasonal variations. As an example, image that you have one loop that does the living room and downstairs cloakroom. Water enters the pipe at say 35°C and exits at 30°C. The cloakroom may only have 3m2 of exposed wall, the other 3 are inside the house. The living room may have 3 exposed walls, with only one within the house, so 50m2 exposed to the outside. Depending on which way the flow goes, the cloakroom may be getting water entering the loop at either 35° or 30°C, so may be either too hot or too cold if the pipe spacing is the same as the living room. The problems start when designers just put in standard UFH pipework spacing and control it all by having multiple loops, each with their own thermostat and flow controller. This is simpler to design, but harder to installer and a pig to control effectively. You may well find that a fixed spacing will work well enough, but without knowing the details, one cannot be certain. So do those calculations, they are easy enough, just tedious. It is what spreadsheets are for.

Depends on the methodology used I think. The formula is pretty simple, just converting an area thermal loss to be expressed as the perimeter length, as I understand it. So if a wall 10m by 2.5 m wall looses 10W.K-1. [That is a U-Value of 0.25 W.m-2.K-1] The perimeter is 25 m so 10 [W.K-1] / 25 [m] = 0.4 W.K-1 This is added to the 10 W.K-1, so 10.4 W.K-1 I think the problems start in defining the U-Value of the perimeter. The easy way is to take the thickness of the wall, rotate it though 90 degrees, and assume that is the perimeter 'area'. So it basically adds the wall thickness to the exposed area. So in the above example, assuming the wall is 0.15 m thick, that will add an extra 0.75 m2 to the surface area, with a U-Value of 0.25 W.m-1.K-1, that is an extra 0.19 W.K-1 losses, giving a total of 10.19 W.K-1. That is different from the initial crude calculation, but in the same ball park, but when you back calculate, 10.19 [W.K-1] / 26.2 [m], for the new perimeter length, you get a value of 0.39 W.K-1 extra losses, so all is well. The difference may well be in the surface losses due to air flow, but I can never remember those values. Your perimeter length may change depending on your wall design i.e. single, double or triple storey and where/how, joists and beams are connected. Window and door openings (expletive deleted) it up as well as they really need to be added as well. The ADDED is the important bit, we get very used to multiplying area by U-Value by temperature difference when calculating thermal looses, but the perimeter losses are an extra loss, so they are additional. (I may be talking out my arse as it is now a good 15 years I since last looked at this, as part of may BSc, but I was thinking about it the other day, I know not why.)

Any help seeing how it comes apart.

So you didn't actually buy it. If you look at purchasing price parity prices, there is not much difference between place in the developed world. Exchange rates and product taxes can often make a difference.

We should go back to a state owned energy company again, many people want it. Then we could have something similar to this, after a decades wait.

It is electrons repelling each other. The Coulomb Force.

Was working in London then, quails eggs and unpronounceable salad stuff.

I went on it before it was closed, I liked it, great views up and down the river.

That's true though only (expletive deleted) don't use GRP. I foresee the board delaminating. Screws are good. Those as well. Personally I like to design in 3 methods of retaining something when it fails. So screws, adhesive and the DC cables. Had a long discussion with a train driver about bricks though the window. It is not all about stopping failure, just making sure when failure happens, it is low energy, predicable and noticeable. You mentioned the Wobbly Bridge the other day. That did not fail, as such, was just a bit wobbly when too many sheep like people walked on it.

Not a beaver then.

While making the classic donkey sound.

Yes, anything that can spread a load is helpful, pick the correct adhesive and it tensile yield point could easily be greater than the screw/OSB interface.

The Port of Rotterdam will take a slice. Most goods that are shipped to Europe, and geographically we are in Europe, go via there, so a bit of double handling. Then there is exchange rate fluctuation, which ever way it is done, the UK, having an independent sovereign currency, will have charges, usually higher than the $ or € as they are currencies that are in greater circulation (so 'collected' by other countries to help stabilise world trade). Then we have high storage prices because we have high property prices. So I doubt that anyone is actually overcharging because they can, we just have high costs of doing business.

Was at a home building show (with our old mate Jeremy Harris as it happened). SIPs was all the rage back then. I asked a salesman about fitting PV to it, he hesitated way too long before answering the it was fine, they had done loads, never had a problem. Those roof panels (the SIP ones) were 9mm OSB.
