They will have to move that rock in the middle of the road, or there will be an accident.

TL:DR Are we talking about public liability insurance (compulsory when doing work for others I think) or product insurance, often called warranty (kind of thing that NHBC charge for).

WTF, that is not a ventilation problem, it is a building design problem. I am pretty sure building built in 2022 should have been designed to combat extreme temperatures. Are your neighbours having trouble as well?

Did they now, quite worrying really. https://bssa.org.uk/bssa_articles/bimetallic-galvanic-corrosion/

Technically they are very useful for stability. One problem, with the UKs pricing system for electricity, is that the developers may be charging £300/MWh, pushing up the price for all power to £300/MWh. That nonsense must stop, it is not a 'renewables' problem as the price to start up a gas plant can be even higher.

I worked on a basement swimming pool in a hotel once, as the pool was being enlarged, an underground stream was breached. I have never seen a project go so seriously over budget.

Think you may have missed a zero. 0.033 W.m-1.K-1

May not be the cheapest option though. Bulk transmission losses are quite low, it is local substation losses that the problem, and we cannot easily get rid of them without serious engineering.

I don't think anyone that works in the planning of wind farms thinks that. Totally agree with that. Where was the other 89% coming from, and are you just talking local demand, or national?

Do they want it, or you going to fly tip it. (We are constantly fighting a battle with fly tipping, disadvantage of a free carpark and a tennent that never locks the gate when they leave)

I am up for it if I can. Don't get carried away, this is our good week, and it is almost over.

This is what Cornwall is like most of the days. And the beaches.

Lots to put in for the 15th. https://www.britannica.com/on-this-day/May-15 Brian Eno's birthday

What, manlove then

The ghost of Heath Robinson. You could have done this to get the same saving.

For real, we have had quite a lot of rain. In fact, when I went to Bodmin Moor to pick up some MVHR pipework on Easter Friday, it was torrential.

All this nonsense about range anxiety. How many people actually drive more than 200 miles in a day. Not many. And as @S2D2 says, 600 miles is possible. (I am an exception and frequently driven 600+miles in a day, a few times a month, and if I had the cash to hand would have a Model 3 LD over a BMW M5, the nearest competitor)

So they are not actually doing it, it is being planned. Quite different from

The majority of people lease purchase, and only do a handful of thousand miles a year, usually very short, urban journeys as well. These are the people that EVs are aimed at, not the isolated rural dwellers or the high milage people. It really is not a technical problem anymore. You got a link to that, or is it just an academic study (been reported in for over a decade). Cleaning up ships emissions has increased solar forcings, and raised global temperature (as has China's improved air quality), but it is not a conspiracy, con, or anything nasty, just a side effect of better technology.

A man well known for his science/technical background and never saying what people want to hear.

Have you worked out the yearly CO2 emissions and the yearly running costs. That is what would make a difference to me. All technology suffers from that. But if you look at the improvements in vehicles over the last 40 years (Allegro to Polo say), the improvements have been incremental, nothing drastic. But in the last decade, you really can't ask for more improvements. https://rmi.org/the-rise-of-batteries-in-six-charts-and-not-too-many-numbers/

That will be in the region of 6 tonnes of CO2. My car is about 180gm CO2/ mile. Last year I drove 30k miles in it. So about 5.5 tonnes. Pretty similar.

Do you know how much they have generated? You can work out the embodied energy/CO2 payback time. Whenever I hear someone spouting on about renewables never paying back the amount of energy they take to make, I usually retort with 'why are they so cheap to buy then'.

But going a long way towards reducing overall CO2 reductions. The same argument is used about wind turbines and the amount of steel, plastic and cement is needed to build them. And EVs using more energy to be produced than an ICE vehicle. If environmental science was easy to understand, and had simple, binary, answers, then no one would have to study it at university. Maybe this will give some perspective. 1972 2022

It was something that was being looked at (not by me) when I was doing mt PhD, over a decade ago. It was in relation to smart fridges. Not sure what happened but at a presentation I pointed out that fridge loads, when running, are very low (a few 10s of watts), but massive when starting up (over 2 kW often, why they have 13A fuses, even on little fridges). You would have to start them all up over a matter of hours in an automated system, a shorter time over manual reconnect as power can be diverted to a zone when reconnected). The grid does not produce a smooth sine wave (or 3). But a rather messy, harmonically distorted one.
