I am still amazed that I have not had to change the brakes on my C-Max after driving 90,000 miles in it. I do not know when they were changed prior to me owning it (bought it at 38,000 miles, so probably not changed). Not sure if it is my driving style, or have brakes vastly improved. Not as if it is a light car and I only drive on major A roads, it is all hilly lanes and towns down here.

Having been away for a while, it is interesting to see that this topic is still discussed. What does intrigue me is that some people think that shifting from fossil fuels to renewables can only harm the economy. What is this based on? "The stone age didn't end because we ran out of stones." @epsilonGreedy Do you know why CO2, or any other molecule, can trap heat? I suspect you don't. As for cars, back in 1996, I had a company Citroen that easily did 60 MPG, it was an AX 1.4 Diesel. Was dreadful. My own car was a 1991 Peugeot 309 Turbo Diesel that consistently did 50 MPG, and in those days it only had two speeds, zero and maximum.

It is the same fib that is said about PV and wind turbines. Probably by the same people. You have to do two calculations (or at least find two datasets). The Well to Wheel emissions and the Manufacturing Embodied Energy. There may be cases where, say a hyper car that is really used, has lower environmental life cycle costs compared to the the daily Tesla S, but that will also depend on where the vehicles are geographically based.

@newhomeStill at the other end of the country from you.

Thanks @Dreadnaught

It was with some waterproof MDF and a bit of ply. The MDF absorbed very little water, less than 1% by mass, the ply not so good, but the adhesive was as good as new.

@Ed Daviesand @TerryE Do a statistical model, some things just cannot be sorted out with a relatively simple equation.

I got a letter today from EDF about a price rice, the second in a few weeks. Generally they were good on price, but not now (though still in business). Hard knowing what to do as I agree with @Triassic, many of these smaller 'piggybacking' companies are going to go to the wall.

Or webbed toes and fingers, like the inbreds from Helston

Just avoid Nalders as a solicitors, they are the most ineffective and useless ones I have ever had to deal with. They added an extra 3 months to my house purchase. Just dreadful.

Wish my girlfriend was an ankle biting mite

I use a Raspberry Pi Zero W with some DS18B20 1-wire sensors and some DHT22 sensors. Also stuck on a real time clock. Very cheap kit, around 20 quid. The chart is just knocked up in Excel, though there is software for the RPi that can do charts on the fly and publish them. The advantage of the 1-Wire stuff is that you can daisy chain many sensors to 1 input pin on the RPI. The DHT22 needs 1 pin per sensors, but there are about 20 spare pins, so that is not really a problem. The software is easy to write, or copy, just depends how sophisticated you want it really. Also pretty easy to get it to turn things on and off i.e. a fan, airco unit, heater.

My house was shut up most of the day, but you can see when the wind picked up in the afternoon and when I got home.

If I had read this earlier, I would have said join me for a coffee down Tehidy.

I think you don't get it. You can dress methods up with meaningless words and acronyms, but, as usual, it comes down to communication between the person who wants the work done and the person doing it.

Seems to me, and taking @Ferdinand's approach to it, that all it is really doing is getting rid of unnecessary layers of management. This allows mistakes to be made, and quickly rectified, without reprimand. Suits some people, not others. As for IT people and self build correlation, there is also a high number of engineers that are terrorists/suicide bombers. I try and keep well clear of software engineers because of that, and the flying spittal when they get excited over finding they have a semi colon rather than a colon, which, mathematically cancels out to leave them with a semi. Which is very worrying.

Quia illa schola cotidie

Oh, good spot, never checked the date. There was an announcement on the news this morning about it. Maybe there is a newer one. This is the new National Planning Policy Framework, maybe it was that the were on about. https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/728643/Revised_NPPF_2018.pdf

It is a White Paper, so has nothing to do with reality. Saw my old Mathematics lecturer last night, think I got his change right.

Isn't that dependant on property size. Have a hunt around on https://www.engineeringtoolbox.com/ as they have all the details.

Or how they are going to make it harder to build house, probably. https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/590463/Fixing_our_broken_housing_market_-_accessible_version.pdf Only 109 pages long

Yes, basically true that a heat pump just cools one side and heats another. If the temperature differences, within the working range of the refrigerant gas, is equal, then there should be no difference. In practice there may well be a difference, but that could be caused by the plumbing side i.e. not capable of pumping enough because of UFH pipe restrictions, surface areas not large enough for the temperature differences, the fact that cool air falls to the floor, warm air rises which will effect efficiency. That sort of thing.

So do I, there is something just wrong about not going upstairs to bed.

Te reason that there is a difference in name place capacity is because of the relative differences in temperatures and entropy. Probably find that if you plot on the Kelvin scale those difference diminish and the only thing affecting it is the entropy caused by humidity.

PV/T = C Where: P = Pressure V = Volume T = Temperature C = Constant (this is for an 'ideal gas', but good enough for this) So separate the the working of the Heat Pump (Carnot Cycle, you can't get better) and the Plumbing, which is just where you want the energy delivered to.
