If you can get an SA in, you can get a water cylinder. That is the physics of phase change materials. You need a pump the energy is at just slightly higher than the phase transition temperature.

It is force (N, mass x acceleration) at a distance (m, metre). So Torque = Nm So basically, the longer the handle, the more torque can be applied. Power (W, kW) is torque times angular velocity (degrees/time, though usually expressed as radians/s) This is why a car engine gives maximum torque a little below the maximum power RPM and an electric car has maximum torque and power at 0 RPM. As for safety, just don't put the drill between your legs (if your are male, females I will not comment on).

I am surprised no one has mentioned this animatronic device. https://www.ebay.co.uk/itm/235247737432

May stabilise the temperature to the ideal growing conditions. Get some hemp seeds (Trill bird food) and see how well it works.

Another way to look at it is that June generation is 12% above the mean (rough figures). How much of that 600 kWh (roughly) do you actually use?

Did you glow when it was cold.

Not really. Only skimmed it this morning.

Just did a DuckDuckGo search and clicked on the link

Heard this on the BBC News this morning and instantly thought of @JohnMo. Did a bit of searching but nothing showing up on the Today website. So had to scroll though the broadcast. 06:10 AM Seems to be based on this FT article. https://www.ft.com/content/2ea6bf6d-04e9-453b-a35f-cd6431cfc7bf Which I managed to read without registering.

Plant the stones and in a few years you can be harvesting your own crop (I have a few planted in pots and may plant them properly one day).

Because of the designs used, they were perceived as temporary caravans/beach huts. I have an American mate who worked in an architects office for many years (did the model making/photography) and when she moved to the UK she heard the term "put all your money into bricks and mortar" for the first time. She still finds it an funny saying and often says it when conversation about our class system crops up (which is quite often when an American is in the room). We seem to have designed a housing system and sell it as a privilege to be a home owner, if you cannot get on the housing ladder it is because of personal failings i.e. you own a phone, have a coffee in a cafe.

I wonder if they could be repurposed to store waste energy.

Usain Bolt would have run that distance in about 6 seconds.

What the (expletive deleted) does that mean.

Almost certainly is the reason. Not only does water take around 5 times as much energy as concrete to heat up, once it start to evaporated, it takes silly amounts. Over 500 times the energy. Been saying it for nearly 2 decades now, but not many people want to believe me.

Really quite a marked difference isn't it. Makes me wonder why people want to add 'thermal mass' when it takes so much energy to heat up.

I spent 8 hours in Tarmac head office telling whoever turned up that I was waiting to get paid. Tarmac were in the national press at the time as an example of a company that did not pay small contracts in time, if ever.

And today's date is?

Well it could be an autocorrect typo.

And add an extra 300mm of insulation on the long North wall.

Not sure old people need instant. Perfect temperature. It's what we keep our house at. About my favourite temperature as well. There is a bit to much hair shirtery when 20°C is quoted, even though that is about my mean temperature.

Not excessively hot and well within the capabilities of all heat pumps. Just a case of designing it correctly and making sure there are not too many losses though the fabric of the building.

@CalvinHobbes What room temperature are you trying to reach? This is what determines your heat source. You can if you want do a combination heating systems i.e. wet ASHP and an A2AHP. I was at my Mother's Care home yesterday, noticed that there is a number of ASHPs on the building. Had a little route about and it seems the place is heated with them, why the radiators do not seem hot, but they are near enough on all the time.
