@Pocster likes to get knocked up in toilets by farm hands. Any help.

Yes. Buy stuff carefully, and don't go silly on technology. Two big things that many think improve their lives are kitchens and bathrooms. Be sensible about those and save yourself £40k. Windows are just sheets of glass in frames. Always remember that. Adding insulation at the design stage is the time to do it, not as an afterthought. Work out which parts give you the greatest return.

I would like to, may have to see if I can fit it in to a trip up to my mother's.

There is a reason we have dull stainless steel at work.

Buy a new one.

I can't, I don't understand it. The model of kinetic energy I have, while only a model, does not fit in this case. But then I don't really understand a lot of the quantum physics, entanglement is one of them, even though I know it is real.

Two things to research then: Converting from Temp/RH to Absolute Humidity (AH) Statistical Modelling

Atoms at temperatures beyond absolute zero may be a new form of matter Physicists have coaxed a cloud of atoms into having a temperature beyond absolute zero and placed them in a geometric structure that could produce an unknown form of matter By Karmela Padavic-Callaghan 7 June 2024 The temperature of atoms is determined by their energy and entropy agsandrew/Shutterstock A cloud of atoms with a temperature beyond absolute zero – which is also bizarrely hotter than any positive temperature imaginable – could be a mysterious new quantum state of matter. Luca Donini at the University of Cambridge and his colleagues have put thousands of potassium atoms into this seemingly paradoxical situation by precisely manipulating their energy levels and quantum states. “Quantum mechanics allows you to do this, while classical thermodynamics would never allow it,” he says. Normally, if you have a collection of atoms that are moving around quickly, with lots of kinetic energy, then the temperature is high. In contrast, slow-moving atoms with little kinetic energy have a low temperature. When all atoms are perfectly still, the Kelvin scale – used by scientists to measure temperature – hits absolute zero, the lowest value possible. But physicists also have a more precise definition of temperature that reflects how energy is distributed among the atoms, a property related to a system’s entropy, or how disordered it is. For a collection of atoms with a positive absolute temperature, only a few of them have lots of energy, while most have lower energy levels. At absolute zero, all atoms have the same, minimal energy. But at negative absolute temperatures the distribution flips so that higher-energy atoms become the majority, and those with lower energy become outliers. This leads to one of the biggest oddities about negative absolute temperatures – they are technically hotter than all positive temperatures. This is because a negative absolute temperature object will always have more energy, so putting it together with a positive temperature object would make heat flow into the latter, as from a warm room into a cold glass of water. Donini and his colleagues achieved this unusual temperature by putting potassium atoms into a vacuum chamber and cooling them very close to absolute zero using lasers and magnetic fields. This allowed them to control the quantum states and energies of the atoms, ultimately coaxing them into a negative absolute temperature. They presented the work at the annual meeting of the American Physical Society Division of Atomic, Molecular and Optical Physics in Fort Worth, Texas, on 5 June. This kind of experiment was first performed in 2013, but now the researchers have carried out a more advanced version that allows them to arrange the negative temperature atoms into a pattern of hexagons and triangles called the Kagome lattice. In this arrangement, the atoms can be pushed into a quantum state where all of their energy comes from interactions with other atoms, but they have no kinetic energy. Physicists are unsure what kind of matter those properties will create, says team member Ulrich Schneider, also at the University of Cambridge, and they now face the challenge of pinning down the properties of this new quantum substance. “We’re going into unknown territory, and we are getting measurements, but interpreting them and knowing what they mean is not trivial,” says Schneider. Achim Rosch at the University of Cologne, Germany, says that exotic and rich quantum behaviours tend to emerge from particles arranged in Kagome lattices because of the very specific energies they can have in this arrangement and because of its intricate geometry. For instance, some theorists predict that the atoms may form a fluid that flows with zero viscosity, an idea that seems contradictory when none of the atoms have any kinetic energy, and so should be unable to move. “There is a slew of possibilities of what could happen in this context,” says Rosch.

Buys a lot of climate change, intergenerational, environmental and political damage as well. Earth’s atmosphere is trapping twice as much heat as it did in 1993 Earth’s energy imbalance, a key measure of global warming, has doubled in the past 20 years, raising concerns about how much heat the oceans are absorbing By Madeleine Cuff 5 June 2024 More of the sun’s heat is getting trapped by Earth’s atmosphere muratart/Shutterstock Earth’s atmosphere is trapping more than twice as much excess heat now compared to 1993, making scientists increasingly concerned about the impact on the world’s oceans. The planet’s energy imbalance is a measure of how much surplus heat there is in the climate system. It is the difference between how much energy enters Earth’s atmosphere from the sun, and how much is radiated back into space. Earth has been absorbing more energy than it emits for decades, as increased concentrations of greenhouse gases in the atmosphere trap more heat from the sun. This imbalance has increased sharply in recent years, according to estimates based on data from ocean buoys, published in the latest Indicators of Global Climate Change study. Between 1974 and 1993, Earth’s average energy imbalance was 0.42 watts per square metre (w/m2), but between 2004 and 2023 it more than doubled to 0.87 w/m2. “The Earth is out of energy balance, which is due to the greenhouse gas effect. There is less energy leaving the system,” says Karina von Schuckmann at Mercator Ocean International, a non-profit organisation based in France. The Indicators of Global Climate Change, co-authored by von Schuckmann and more than 50 other climate scientists, is published annually to provide an update on the state of the world’s climate. It follows the same methodologies as the Intergovernmental Panel on Climate Change and aims to act as an interim update to the IPCC’s comprehensive, but infrequent, assessments. The most recent IPCC assessment, which was published in 2021, estimated Earth’s energy imbalance at 0.79 w/m2 during the period 2006 to 2018. The energy imbalance has been increasing since the 1970s, due to increased greenhouse gas emissions and lower air pollution, which helps bounce heat back into space. Previous studies, using satellite sensors, have concluded that Earth’s energy imbalance has doubled since 2005. This is worrying news for the world’s oceans, which are absorbing around 90 per cent of this excess heat. The oceans have been warming at record-breaking rates every year since 2019, research shows. The oceans are “our sentinel for planetary warming”, says von Schuckmann. The additional heat is warming ocean waters, making them less effective at capturing CO2 from the air, driving sea level rise and severely affecting marine life. Some of the changes could be permanent. Recent studies also suggest the excess warmth is penetrating into the deep ocean, to depths of up to 2000 metres. This heat will take thousands of years to resurface, and in the meantime could affect ocean currents, oxygen levels and marine chemistry. “Earth energy imbalance is not just some sort of esoteric quantity that scientists like to look at. It’s got real world implications,” says Norman Loeb at NASA Langley Research Center in Virginia. Studies also suggest the rate of acceleration in global ocean heating has increased over the past 20 years, indicating the rate of change for Earth’s energy imbalance is also rising. This may be in part due to a diminishing albedo effect – as warmer temperatures melt snow and ice, there is less white surface on Earth to reflect the sun’s heat. The rate of increase has jumped sharply even since the 2022 Indicators of Global Climate Change report, which estimated the energy imbalance at 0.89 w/m2 for the 2010-2022 period. This year’s paper puts it at a record 0.96 w/m2 over the 2011-2023 period. 2023 was a record-breaking year for air and ocean temperatures, driven primarily by climate change and a global swing to El Niño, a natural climate variation that brings warmer temperatures. The jump in energy imbalance in 2023 is probably due to the sudden swing to El Niño, says Loeb. “Traditionally, when you have La Niña, the climate system takes up energy. And then when you have El Niño, it releases energy,” he says. “When you go from La Niña to El Niño, it packs a big punch.” Alongside warnings about the increase in energy imbalance, the latest Indicators of Global Climate Change study also cautions that global average temperatures are rising at 0.26°C per decade, double the pre 1983 warming rate. With emissions at the current level, the world has just five years left before the 1.5°C temperature goal is broken. Journal reference: Earth System Science Data DOI: 10.5194/essd-16-2625-2024

Shorten the shower times. My shower uses the same amount of water as a bath half decent bath full.

I think most chalks are water based acrylics with plasticisors. Most paint isn't.

I think you are on a hiding for nothing trying to estimate internal RH from external data. RH is based on empirical data, not a formula, so even the best models are not correct (though good enough). Ask another question, i.e. what is an acceptable level of RH for a given temperature range.

Kernow is a different county. And has a lot of inbred wankers in the council.

It is not as simple as that. To find that out you would need two identical units, both with the same parameters, with the only difference being the gas. And that is not how heat pumps are made. Pick the one that suits your needs.

Welcome. I know Buckinghamshire quite well, I go there every couple of weeks. What is your nearest town?

The heat load (energy) will be 48 kWh\day. To pump in that much energy in 6 hours you need a radiator that can deliver 12 kW (power).

Here is a way to work out the loads, then you can calculate how much mass to add to counteract them. https://www.structuralbasics.com/wind-load-calculation-on-walls/ Wind speeds at ground level are very low, and short of the shed being at the top of a hill, are significantly lower than the Met Office shows, which are measured at 10 metres.

No. That was the Olympian Helen Glover, a fair Penzance maid. I am about half a mile from her Golden Post Box at the moment.
