I didn't think it was reactive but that the heat will kill a river apart from algae etc. Around the Dungeness maelstrom were hundreds of seagulls after fish that are attracted to the warm water. This is a dormant station so presumably was on tick over. There are tales of Mediterranean creatures being found on south coast beaches bug I've no idea if there is any link.

That sounds naughty but is better than just letting the soakaway fail. In reality you are holding back exceptional water which is a good thing. Use it for the garden or pump it back into the soakaway in summer.

Membrane is permeable so not appropriate. Yes water tanks are expensive because they are for potable water and have to be strong. For the garden you could use IBCs which are 1m3 and cost about £50 second hand. You can link them with tank connectors. How to stop them crushing underground? IBCs have the metal cage, so I'd wrap around that maybe with some old cladding or ply before backfilling.

In my mind is that I had a 'special' visit to Dungeness and the hall was vast... it made me think of James Bond final scenes but bigger. Also that the cooling water was jettisoned at sea, making about 100m circle of turbulent hot water. That is a mile out in the English channel so would kill any river surely. Good explanations all, and I am now a little wiser.

Religious Education? I've seen the pictures of God sending lightning bolts from his fingers, but no wind turbines.

OK. Fire first. If a building near a boundary is on fire then it must not be allowed to spread to adjacent buildings or materials. We assume an empty plot will be built on. So the wall on that boundary must stay standing even if the rest of the building is collapsing and trying to push or pull it over. So, let's stick with steel portal frames. The turning forces in a collapsing building are huge and we have a very chunky column fixed down very robustly. Beneath that the foundation also has to be over a big area to resist turning. That is a fixed base. Again to confuse the staff in the warehouse by staring.. you will see that the column is chunkier on that wall than on one facing the car park. On a gable wall everything is lighter. Where it isn't a fire wall, the portal column can be skinnier at the base, with few bolts and the foundation is also much smaller, only taking vertical loading. That is a pinned base. Not usually literally pinned but sometimes they are. On a 30m span shed the boundary foundations might have 5m3 of concrete each, and mustn't cross the boundary, while the others have 2m3 or so. it's all money. My business used tapered columns (and rafters) for best value, and they were thin at the bottom to deep at the top, except on fire walls. The depth of section mirrored the forces. The fire wall cladding is fire rated, and the columns usually need to be protected too. That's all a bit messy and bitty but I hope makes sense.

But you are today's winner. 🏆 💐

Next time you are in a big steel warehouse, look at the rafters. They will be very slender if well designed. To prevent rotation/ out of balance of the rafter, there can be angled struts from the bottom flanges to purlins.. a small amount of steel adding much strength. 350°C , as mentioned by Gus, is very hot indeed. By the time that temperature is reached everyone is gone a long time ago, and most contents will be too. Windows will fall out, doors will fail, skylights will burn or break and so some heat will escape. Ouside walls may even fall apart or burn. Or if it stays intact the oxygen demand doesn't keep up with the fire. The fire bbrigade'sprimary mission is to save life and that is long before 350. But also the fire must not spread so boundary walls and compartment walls are to a higher spec, and steel columns must stay in place. That moves us onto pinned or fixed bases which may be for lesson 2 (only if requested).

I'm not really . I'm being perhaps being lazy and vague. I mean readily renewable, not laid down millions of years ago. Not my understanding. Unless the climate change is all down to pollution rather than energy release. Small nuclear sounds worrying. If VW, Dacia (and some others) start putting it in cars we have to worry a lot about the quality control and back-lot mechanics. (Easier to express for cars than with ships)

That's me, and most on here: thanks for acknowledging. Yours is a list of negatives though, some not limited to wind and some rather, if I may say so grasping. So would you like to complete your version of the pos and cons? Ie balanced not extreme. Please include pollution and health as well as economics. On which we live in a fairly remote SE rural place. But we really notice the difference in air quality (much better) when north of the Forth/Clyde.

The jobs thing is interesting. Whisky is oft quoted as a major employer. It is significant for the nearby village (a visitor centre problem has more employment than the production) but isn't on a regional or national scale.

I know it makes radiation and is dangerous but I've just twigged something. Boffins comments sought. Wind, sun and water all provide a fairly closed loop of extracting energy from current nature and releasing it as heat almost in real time. Effect on the planet fairly small.(?) But can a boffin confirm that nuclear does not have this benefit? Oil coal and gas are energy stored over millions of years , being released over tens. Bad. Burning timber from commercial forests is the sun's resources collected over a few decades. But Nuclear energy was created in the Big Bang, quite a whike ago, so is adding to heat gain in a sudden manner and is not "renewable". Bad. So we should only use sun, wind, hydro and tides, but perhaps some timber from waste, and from rubbish.

A read back will show that I have " got it" thoroughly. I am deeply in favour of non fossil- power (not so sure on nuclear). But, as ever, it needs a plan and policies for all, not left to the free market or the usual snatching of resources from otherwise neglected communities. Hence my proposal for a big electric meter at each development, and the tariff going to your local council

If the hoist hadn't been to hand, this guest might have been tricky to evict. Other than by messy gruesome means and some decorating. This might have been where it was born... feeling guilty now. this introdudes a practical matter: does anyone know a source of very light duty mewps to buy for changing of light bulbs 6m up? No more doing it by standing on a chair. A genie lift for a person.

Sounds as if it is straightforward. The SE will show piers and specify a lintel. Bricklayer forms the window opening which the window supplier measures (don't order by theoretical window dimensions as they can turn out different. , but you can get a quote from it).
