So all the computing power in public education, national health, local government etc was paid directly by the user. Is it that you perceive a high personal cost to mitigating climate change, rather than anything that the scientist come up with. You use that data just to further your argument that it will cost you personally. This phenomena has been studied. There is no need to answer that last bit as I am off out to enjoy the unseasonally low temperatures I have down my neck of the woods.

That is because we have a vast knowledge base now, along with better communication. I do struggle to understand where you are going with all this. Did the scientists that created your PC (or Mac, or whatever) have an agenda to corrupt information, or the scientists that developed air travel to its current level want to kill people with a software problem?

I used to work in the health and leisure industry as a supplier/installer. If the pool is indoors, make sure that all fasteners are not affected by the chlorine, it caused the rebuild of St Albans leisure centre roof back in the 1990s.

Or just an old university lecturer trying hard to educate

Probably not that different. Most of a vehicles mass will be steel for a normal car. Some EVs are made of aluminium, which has a high initial embodied energy, but low when recycled. I am not sure what the embodied energy of the batteries is, but probably not as high as people think. As an example, Aluminium has a typical EE of 155 MJ/kg, when recycled it is 29 MJ/kg. Steel is around 45 MJ/kg and 32 MJ/kg when recycled. I have seen figures of between 350 to 650 MJ/kg for lithium ion batteries. A litre of gasoline has about 45 kWh of energy in it (about 25% is usable for motion in a road car). So taking worst case, a kilo of lithium batteries is the same as 4 litre of gasoline.

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.
