A vacuum is a much better insulator.

Yes

I'm not saying it's a good idea but... If you use solar power to drive the cooler then the heat (including the waste heat from the electrics etc) is exactly the same as if the sunlight just warmed up thee ground. The conservation of energy leads to the question "how could it be different?". I realise the temperature of lakes will go up more or less in line with global warming. But is there any reason to believe that the lakes are particularly susceptible? Why focus on cooling lakes rather than, for example, cooling fields?

Unfortunately, I can't see that being cost effective. There's no reason to assume that lakes are much warmer than they were before mankind got involved.

Freeze it until it's not "rubbery" then machine it quickly.

What on earth did you study?

If you are seeking to mix gases, I have good news for you; the laws of thermodynamics are on your side. If you arrange the gas feeds to the tube to be fast and tangential so that they "swirl" down the pipe, they will mix very rapidly.

Where does one get the BaFeO5 from? It's hard enough to get https://en.wikipedia.org/wiki/Barium_ferrate And someone is suggesting taking another couple of electrons of the iron. I don't doubt the existence of Fe 8+ ions in the sun, but I don't imagine they have any chemistry. Much as I like reading old textbooks, I don't always accept their claims at face value. The difficulty with doing analysis to determine the oxidation state of the iron would be great today and I simply don't think they would have been able to guarantee accuracy back then. (This might be one of the examples of Mossbauer spectroscopy actually being useful.) Certainly the WIKI page doesn't say anything about Fe(VIII) https://en.wikipedia.org/wiki/High-valent_iron They were. I have a copy from 1962. It mentions the carbonyl complexes as examples.

It's not an either/ or thing.

Have you seen this?

I wouldn't say you were a nobody...

No. The shareholders own them. And the rest of your post isn't much better.

It's late on a Friday... Reevaluate Gin Mix.

The plan is to give vast sums of money to an industry that is already making a huge profit from the turmoil of war. Then to get the taxpayers to pay for that handout. The rationale behind this is that the government is paid by the energy companies.

Does that mean it's a video on polyester on polyester?

Most natural fibres, derived from plants, are essentially made of cellulose https://en.wikipedia.org/wiki/Cellulose Silk is largely a protein called fibroin https://en.wikipedia.org/wiki/Fibroin And wool is mainly keratin. https://en.wikipedia.org/wiki/Keratin Some artificial fibres are made from reconstituted cellulose. Nylon could be any of a number of polyamides https://en.wikipedia.org/wiki/Polyamide And polyester is an ester of ethylene glycol with terephthalic acid. https://en.wikipedia.org/wiki/Polyethylene_terephthalate There are some others. All of those materials are intrinsically white. The colours are due to dyes mixed into the fibres or added onto the surfaces. For example, for cotton, those two or three processes are Harvesting ginning carding spinning mercerising dyeing weaving, cutting sewing. I may have missed two or three.

It's a great idea. Perhaps we can implement it. But given that the last Prime minister lied to the queen and got away with it... I'm not royalist, but I think that any alternative head of state would be roughly as expensive, and less good at attracting tourists.

Stunt plane wings are, I'm told, "thick" because they have to be strong, and more or less symmetrical. They are pretty nearly "fins". If you take a flat fin and streamline it a bit you get the sort of wing you see on aerobatic planes https://www.amaflightschool.org/getstarted/how-do-i-know-difference-between-basic-trainers-aerobatic-trainers And if you then tweak it to reduce the drag caused by turbulence behind/ above it, you get a conventional aerofoil. Nobody cares about the fuel efficiency of stunt planes, but they have wings that look like dolphin fins in cross section.

That the cross section of the wing isn't what matters. The angle of attack is largely responsible for lift.

Well... that is her title. It's like referring to Biden as "president". What do you expect them to call her "Granny Windsor"?

An interesting question is how well should a flat "fin" work in air. A rocket with a fin (on each side) will follow a curve because the fin provides as "sideway" force. if you turn that on its side the sideways force becomes lift.

Really? I'm sure Peter Sutcliffe would have been grateful for your support https://en.wikipedia.org/wiki/Peter_Sutcliffe He went to jail for doing what he believed was the right thing.

Why? Why can't it arrive a bit later? The air can sort itself out later by swirling about. It's not like having two queues of people going through customs barriers where the couples need to meet up afterwards. The "it goes faster over the curved surface so.... Bernoulli... it generates lift" explanation is clearly wrong. You can fly stunt planes upside down indefinitely. At the very least, you need to consider this as well. https://en.wikipedia.org/wiki/Coandă_effect

Pandemic is not a "level" it's a distribution. But, assuming you continue with your "unorthodox" definition, when the number gets above 100 again, will you accept that you are wrong? Incidentally there were actually 3 elements to his "justification". One was that covid is over the second was that we have finished with brexit and the third is that the war in Ukraine is no longer an issue. There's a pattern here and it's that JRM is either an idiot or a liar (or both).
