I can understand the ends being different to an RJ, but if the cabling is normal POE CATxx then if the manufacturers wire it differently, they are just being twats. Why have international standards and then modify them. Makes more work for everyone.

Thanks, I had forgotten that this was happening. ETS has been quietly plodding along in the background and does not seem to have affected costs too badly.

Carbon intensity per $GDP is a key indicator and should maybe used more when imposing tariffs. https://ourworldindata.org/grapher/co2-intensity USA 0.26kg/$ UK 0.12kg/$ France 0.11kg/$ Germany 0.17kg/$ Japan 0.22kg/$ China 0.43kg/$ India 0.27kg/$ Australia 0.29kg/$

A friend of mine is an American and she worked for a large architectural company. She had never heard the sayings 'as safe as houses' and 'put your money into bricks and mortar'. They do teardown and rebuild a lot more than we do, use fractures to produce structures, don't piss about on site, generally have a more relaxed view in planning, and I think the codes they work to are easier to understand. As for the sizes of the houses, the UK has disgustingly small houses. We should be ashamed of our housing, and of the industry I general.

That is part of the issue, the weather regimes are very different.

And no vapour control layers, insulation, ventilation control. Many then had a large gas boiler fitted that was run on a timer, this caused condensation issues. (I had a 1910 terrace and it was awful, but if I had known in 1984 what I know now, I could have improved it no end)

Like most things it hits a fundamental physical limit. I think one of the problems in engineering is we all got duped by Moore's Law. While this held true for micro electronics, it was not true for engineering in general. Moore's Law was really an engineering/manufacturing/quality challenge, not something fundamental about silicone. (Someone on here described building a chip as akin to making a pinhead sized working replica of a Spitfire, but only using normal hand tools)

Yes, this is how I set up check lists at work. One can usually find the person who has forgotten all about it.

Which will enshittify the world even more. What amazes me about these scams is that the creators have a flair for marketing/advertising/promotion/sales, and then take a risk by selling total crap. They could use the exact same skills they have and sell viable goods, and probably at a higher markup. I used to work at one of the largest jewelry retailers in Europe. The markup was about 10 times the wholesale price. It is never worth stealing jewellery, you may, at best, get 20% of the wholesale value. Not really worth it.

I agree. May have mentioned this before but someone I knew was banging on about the high cost if heating his mother's flat. Was heated by electrical panel heaters. I suggested an A2AHP, but he decided that portable oil filled electric 'radiators' where better. A few weeks later he told me that his mother's bills had been greatly reduced. I pointed out that it was now spring and a lot warmer (∆T now 5K rater than 25K). No, it was the new heaters. He kept quiet about it this winter. Some people think buying something new will always be an improvement.

Can't we not put rare earth magnets on a fan blades? It works to soften water, improve fuel consumption, cure headaches and rheumatism, it just has to cool air.

Not sure, but I seem to remember that forced induction engines follow a different cycle. Not that it really matters in the above cases.

Yes.

I think we would be better off slashing education budgets and reducing the checks on online sales. Let the 'hard working family' loose their money, it is theirs to loose.

Efficiency = 1-Tcold/Thot So like any reciprocating engine, it is going to be pretty poor.

Environment Earth is heating up faster than at any time in its history To understand where climate change is heading, we have to look at the planet’s distant past and appreciate the disturbing uniqueness of our situation, says Bill McGuire Bill Mcguire24 July 2026 http://localhost:56805/wp-content/external_image/aHR0cHM6Ly93d3cubmV3c2NpZW50aXN0LmNvbS93cC1jb250ZW50L3VwbG9hZHMvMjAyNi8wNy9TRUlfMzA2MjUwNjQ2LmpwZw__.jpg Rising levels of carbon dioxide in the atmosphere are trapping more heat Bill Gozansky/Alamy As Europe bakes in what could be its hottest and driest summer on record, the rapid transformation of our climate is harder than ever to ignore. But how much hotter will it get, and what will that mean for life on Earth? To get a picture of our future, we can either use computer models or look to episodes of rapid climate change in the geological record. While models are invaluable in terms of tracking where our world may be heading, peering back into deep time provides unrivalled information about cause and effect; about how the climate has changed in the past and what the consequences were. There is no guesswork involved, as the evidence is all laid out for us in the sediments and rocks, in the ice sheets and in the remains of ancient life. Looking back in time also helps us to put human-caused global heating in context by making comparisons with past episodes of rapid temperature increase, and when we do this, the news isn’t good. It isn’t so much the degree of heat that is the issue – our world has been much hotter than it is today for much of its 4.6-billion-year history – but the speed of change. Perhaps barring the immediate aftermath of the dinosaur-obliterating asteroid impact 66 million years ago, atmospheric carbon dioxide levels have never risen as quickly as they have in the last couple of centuries. Even worse, nowhere in the geological record is there evidence for the average temperature of our world climbing as quickly as it is now. This means 10 times faster than during the Palaeocene-Eocene Thermal Maximum, which marked extreme hothouse conditions 56 million years ago, and at least 20 times faster than at the end of the last glacial period. Judicious analysis of past climates also permits us to recognise potential analogues for where our world is heading in the decades and centuries to come. Over the last 50 million years or so, the planet’s climate has followed a broadly cooling trend, which we are now rapidly rewinding – a process, if you like, of prehistorification. Deciding how far back we will end up is still within our gift, but it is a given that our grandchildren will grow up in a climate different to any experienced during the tenure of human civilisation. Modelling studies suggest that if – and it’s still a big if – emissions peak by 2040 and then fall quickly, we will rewind the climate clock 3 million years and bequeath to our descendants a Late Pliocene climate. Then, atmospheric CO2 levels were much lower than today, at 330 to 400 parts per million (ppm), but the temperature was between 2.5ºC and 4ºC above the pre-industrial average, and sea level 15 to 25 metres higher. Pliocene conditions could start to appear in the continental heartlands as soon as the 2030s and spread out from there. If we fail to rein in emissions fast enough, or if natural feedback effects drive more heating than expected, then a further rewinding of the climate clock back to the Miocene becomes more likely; to a time 15 million to 17 million years ago, when CO2 concentrations, at 400 to 600 ppm, were a bit lower to moderately higher than they are today. At 6ºC to 8ºC above the 1800s, however, the temperature was far higher than expected for such CO2 levels, suggesting the involvement of other heating factors that we don’t yet fully understand. Sea level was maybe 50 metres higher than it is today. But this may not be the end of it. The current high rate of heating documented by satellite observations and borne out by Earth’s rapidly escalating energy imbalance implies that rewinding the climate clock back fully 50 million years remains within the bounds of possibility, eventually reprising the blistering heat of the early Eocene hothouse. Such conditions would make most of our world uninhabitable for humans, and severely test the capacity of our species to prevail. As the Persian poet and mathematician Omar Khayyam observed almost 1000 years ago: “When I want to understand what is happening today, or try to decide what will happen tomorrow, I look back.” They are words that serve us well as we contemplate our future climate, and that we ignore at our peril.

Related Environment This El Niño will be the hottest by a huge margin The super El Niño now developing in the tropical Pacific has a 90 per cent chance of becoming the strongest in 150 years, breaking global temperature records and unleashing extreme weather Alec Luhn23 July 2026, updated 27 July 2026 http://localhost:56805/wp-content/external_image/aHR0cHM6Ly93d3cubmV3c2NpZW50aXN0LmNvbS93cC1jb250ZW50L3VwbG9hZHMvMjAyNi8wNy9TRUlfMzA2MjI1Mjk2LmpwZw__.jpg El Niño events are linked to dry weather in Australia, which can lead to devastating wildfires such as those in 2019 SAEED KHAN/AFP via Getty Images The planet-warming super El Niño now developing will almost certainly be the strongest ever, breaking the record by an unprecedented margin. Out of hundreds of simulations by 14 forecast models, 90 per cent predict the tropical Pacific will reach a sea-surface temperature anomaly that hasn’t been seen in 150 years of observations, according to the California non-profit organisation Berkeley Earth. It is expected to peak at 3.6°C above average, far above the 2.75°C record set in 2015-16. Zeke Hausfather at Berkeley Earth says this is one of the few times a climate forecast has truly shocked him. “Even the median of all the models expects we beat the record by 0.8°C,” he said at a media briefing on 23 July. “If this does end up occurring, it really would be record-shattering and unprecedented.” El Niño happens when easterly winds weaken in the tropics, allowing water they’ve pushed into the Western Pacific Warm Pool to wash back towards the eastern Pacific. Rainfall shifts eastward, weakening easterly winds further in a self-reinforcing feedback loop. Although it’s a natural cycle, it delivers a jolt of heat on top of 1.4°C of global warming, setting off extreme weather around the world, according to Berkeley Earth. Already, this El Niño is revving up faster than any previous event. Sea-surface temperatures in the central-eastern Pacific have reached 2.1°C above average, vastly outpacing the 1.6°C increase seen at this time of year during the 1997-98 El Niño, the previous record-holder for speedy development. This “explosive onset” has already put the event in very strong or “super” El Niño territory, only a month after it started. And once you consider that El Niño doesn’t peak until late autumn or winter, it really does look like the world is facing a “Godzilla” El Niño, the name given to those that increase temperatures past a rise of 3°C. Within a few months, the huge swathe of warm water across the Pacific will heat up the rest of the world. Global temperatures in 2027 are likely to reach 1.7°C above the pre-industrial average, smashing the record set in 2024, when temperatures were 1.5°C above the average. The El Niño is coming on so fast that there’s even a chance 2026 will break that global temperature record first, as some have predicted. As a result, the 20-year temperature average will likely exceed 1.5°C by 2029, failing the goal set by the Paris Agreement, said Robert Rohde at Berkeley Earth in the briefing. “We’re already over 1.4°C, so there’s very little margin left,” Rohde said. Different regions will see different extreme weather. Densely populated southern China could experience heavy rainfall in the spring and summer, raising the risk of flooding on the Yangtze river, forecasters have warned. The 1997-98 super El Niño caused flooding on the Yangtze that killed more than 3000 people. The north-eastern US tends to face drier conditions during El Niño, while the southern US gets wetter, which can unleash mudslides in places like California. Australia tends to dry out, raising the threat of bushfires like those seen during the “Black Summer” of 2018-19. India, southern and central Africa and parts of Central and South America all face drought risks, which could push up the price of commodities like rice, coffee and chocolate even in less-exposed countries like the UK. “We might get lucky and have smaller reduction in rainfall in Africa or India, but generally… the damages scale with the strength of the El Niño,” said Hausfather. Strong El Niño events also cause harm to ecosystems, such as widespread coral bleaching, which is expected this year as well. While some research suggests El Niño events are getting stronger, other studies disagree. What is clear is that the impacts will get worse as global warming accelerates. “It’s something we need to start preparing for today and make sure we have systems in place to deal with drought conditions,” said Hausfather.

Why not just mandate A2APHs and EAHPs for water heating and ventilation. 2 jobs done in one hit. Oh hang on, burning means it's working. Can't remember where I read that.

I think they would be getting a telling off if they tried to deny it. There is only so much negative spin that is allowed. I have a soft spot for the Telegraph as it was the daily paper at home, Sunday Times on Sunday. Not bought either for over a decade now.

According to Wikipedia 2 billion tonnes of oil are moved each year. If water, that would be about 2.2 bt. If we take a conservative usage of 1 tonne/day.person to cover everything (includes agriculture, industry etc), the UK will need to ship 24 billion tonnes a year (65m people by 365 tonnes). Don't think Captain Pugwash is up to it.

I have just started reading this by Hannah Rictchie _OceanofPDF.com_Clearing_the_Air_-_Hannah_Ritchie.pdf

Yes

Forgot about this on my doorstep. 3MW electric and some thermal. I think they are selling on the back of lithium extraction. https://gel.energy/about/united-downs/ https://www.bbc.co.uk/news/articles/cewzg77k721o

Which bit. Here is the radio active decay. https://en.wikipedia.org/wiki/Earth's_internal_heat_budget Here is the tidal heating. https://en.wikipedia.org/wiki/Tidal_heating About 0.0073 W/m2 most in the oceans, so not really relevant. All these thermal forcings are generally measured at the mW/m2 scale. As much as I line innovation and large engineering projects, we currently do not have time to wait for the Golden Goose. We need to crack on with Wind, Solar, Hydro, Storage and Demand Management. We have everything we need to do that, and have actually had it for the last 30 years.

A bit, most is radioactive decay There is some tidal warming. It is a bit strange to go to all this trouble when there are easier alternatives to develop. https://goexplorer.org/using-the-ocean-to-power-tropical-islands/ They spent, I think, £1.5m on the Jubilee Swimming Pool geothermal project. It failed and they put a heat pump in. Seems strange when they have a warm ocean literally 10 feet from it and a local firm that makes Water Source Heat Pumps. I am sure I could get an AI to write up a gushing proposition for just about any energy source, present it to some greedy, but ignorant, investors, and laugh.

We currently have mines deeper than that. They will almost certainly have to pump out water. https://en.wikipedia.org/wiki/List_of_deepest_mines The UK has mines almost as deep. https://en.wikipedia.org/wiki/Boulby_Mine They probably could have mined deeper, but they stopped at the resource they were after.
