There is a lot of Talk about climate change. One word saves a lot of hand waving.

Good word, especially on a forum.

The problem with a 'plasterboard tent' is not just the extra heating cost, it can cause damage to the frame because of uncontrolled condensation. So while it may technically pass the air test, it is still faulty.

What happened to our old forum member @Construction Channel

I worked for a small turbine manufacture almost 20 years ago, even then a 4 or 5 kW turbine would have been close to £20k. They have never been cheap. PV was a similar price back then.

"Greenest Government ever" Followed by "Get rid of all this green bollox" As we are into the third week of this oil crisis (I have been though a few), we cannot be far off what it would have cost us to have tripled our wind and solar capacity and kept the subsidies on BEVs. https://www.theccc.org.uk/2026/03/11/cost-of-net-zero-by-2050-less-than-a-single-fossil-fuel-price-shock-ccc/

If you are going to have any pictures hanging on the walls, you can line the back of the them with carpet, quite effective. Alternatively, you could experiment with a 'sonic crystal'. Lot of playing about to find the correct length, diameter, density and orientation, but can make for an interesting bit of art in the room.

Different vapour permeability, it may be important.

Can model all that with a 3 Parameter Weibull Function.

I can testify to how hard a Cornish Hedge is, totally unscathed after a glancing blow at 60 MPH.

Going to be equinox in about 50 minutes, more time to generate PV.

Part Two: The Spark Gap https://www.bbc.co.uk/sounds/play/m002sr4f Dale Vince and Greg Jackson falling out.

I worked with an electrician and he had a very long, flexible, coiled steel spring, with a light at the end. Was a simple bit of kit but made pulling cables through easy. No idea where he got it from, or if it has a name.

Be cheaper to buy non bifocal ones then.

I work at a place that refuses to have systems in place. The rule seems to be to use any exceptions as the normal practice. It's a (expletive deleted)ing disaster. Took me 2 years, bollockings and general tantrums to get a drip tray emptied every day. Takes about 20 seconds to do it. The reason given for not doing it was generally 'it was not full yesterday'. (expletive deleted)ing overflowing onto the floor now though, isn't it.

If the panels are going on a roof, how does the bifacial part work?

@saveasteading and other interested parties Here is part of it, no tape measure needed ( @Pocster ).

I asked AI and got rejected. So try GQT, they usually have an answer, sometimes a humours one. Many years ago I stumbled across Geoff Hamilton's gardens at Exton (I scrumped a ripe apple off his tree). Fantastic place for inspiration. @Omnibuswoman just get a local pass for The Eden Project. It is always warm and dry there.

Electric fence, will keep sheep away and may shock a CH driver as well.

Maybe @craig can shed some light on this, he has people out measuring I think.

Donna Donna still got no knickers on er. (I can't look at Christmas reindeers without saying that out loud when children are about)

Maybe a tiny bit more understanding than the recipient of the drawing/file. The problems usually arises 'on the shop floor', not in the drawing/engineering office. We have similar problems with our food allergy records. We can buy the same product but find that the ingredients have changed. Nothing gets mentioned by the wholesaler or manufacturer. It is getting to the stage where we just tell customers that everything has whatever they don't want in it, in it.

Isn't an engineer the man that fixes your washing machine in the UK. Chartered Engineers are what are really needed.

Was more to show how easy it is to be 50mm out. In real life the problems are accumulative errors and systematic errors. Get two workers with their own tape measures and errors can be quite serious even over a few metres. I never trust tape measures, they are only good for relative reference, withe the relative reference being themselves. Somewhere at home, in my vast library of mathematic's books, I have one a about using a rule and compass to establish mathematical concept. Shall see if I can dig it out and find some relevance to absolute geometric referencing.

Re taking diagonal measurements. Quick sketch below show what one, half degree out, but correct length does.
