Driving Too Slow

You didn't factor in the transportation cost of the electricity. The losses are not large, but it starts eating into the CoP margin. The real issue is the cost of the installation. A heat pump requires backup heat for when it's not very effective such as low temps but also for removing ice from the coils. To do that they run it in air conditioner mode and run the backup heat to keep the house from cooling off.

Heat pumps are tricky to get a fix on their true effectiveness. The CoP only covers the normal operation of the heat pump basic function. In the US they invented a measure to factor in all inefficiencies called SEER. But there's no useful way to turn the SEER number into something technically useful other than just comparing it to the value for other units.

Yes, more complexity is great! To heat water in a tank, I would use solar heat to reduce the primary heating source. These can be very inexpensive and very cost effective.

No joke. Widely publicised. Wide gaps on supermarket shelves where carbonated drinks should be displayed.

I don't think it quite reached the stage of screwing meat production where CO2 is used to stun/kill the animals. Brexit and "reclaiming control of our borders was sufficient for that.

Deregulated with the aim of minimising prices (sotto voce: in the short term), and run by a court jester.

No more than you do.

At least _I_ clearly delineate the limits of my knowledge of the specific facts.

Martin Brown clearly states where /you/ just make things up out of sheer ignorance. I have done the same in the past, and /eventually/ you began to concede that your personal experience does not translate into the rest of the world.

Oh, you have "forgotten" the pictures I posted when you previously claimed charging EVs was easy.

A couple of examples from my local knowledge...

Yesterday I was looking at houses for my daughter in Cardiff, the capital city of Wales. Here's one, where not only is parking outside the house illegal (see the zig-zag lines), but we had to park on a different street 100 yards away. https://www.google.co.uk/maps/@51.486144,-3.1470046,3a,75y,39.05h,87.19t/data=!3m6!1e1!3m4!1sjw4PVbayoLiJXAUEIcjjPg!2e0!7i16384!8i8192 Here's another, in an expensive part of a city with large conservation areas. Please indicate how a top floor flat resident would charge their car. https://www.google.co.uk/maps/@51.4695176,-2.6173275,3a,75y,9.71h,98.29t/data=!3m6!1e1!3m4!1sw-bqPg3m9lsW_d_NOf_AXw!2e0!7i16384!8i8192 My parent's house there /does/ have a driveway. That's a /major/ selling feature, and is worth a /lot/ of money.

You are the one who has learned nothing.

In many parts of the UK your outlet would be hundreds of yards away on a different street, and often 100ft in the air. In such places there's little possibility of installing a public charging point due to lack of space on the pavement, number required, and sheer cost - let alone being in conservation areas.

The same is true in many European cities, and I probably Asian cities.

No.

We import it from places with cheap hydro, e.g. Iceland.

Three years ago, Britain’s last major aluminium smelter, Lynemouth, was closed. This followed the closure of the Anglesey plant in 2009.

An industry, that used to boast of production figures of 300,000 tonnes a year, is now reduced to the tiny Lochaber plant, rated at 43000 tonnes.

The reasons for these closures was well documented at the time, and the major one was high energy costs, largely due to UK climate policies.

That would require joined-up thinking and forward planning from politicians that believe free markets will solve all problems.

Hence it is highly unlikely :(

I am well familiar with pricing. I know that spot market prices are insanely high and *that* is what our government has committed us to for gas supply for electricity generation. They shut down the last decent sized UK gas storage facility about 5 years ago. They are quite literally buying on the spot market and paying over the odds to divert LNG tankers to the UK *right now*. I agree that it is insane, but it is exactly what you get by deregulating and short term profit motives.

Nowhere near. They are buying LNG in tankers at *huge* expense. Buying on the spot market and having a JIT system for gas with virtually no buffer stock means they are absolutely at the mercy of price gougers. Strictly it isn't price gouging so much as what the market will stand!

To many countries decarbonised in the dash for gas. Now that Russia has throttled back the gas supply to Europe there is insanely high demand for gas to keep the lights on at *any* price.

This doesn't look temporary. The whole of Europe will lose electricity if the s*it hits the fan.

France still has worthwhile nuclear capacity but the rest will be toast.

Not at all - it threatened food supplies for Xmas. They *had* to do something - the company wasn't prepared to run at a loss. It is yet another side effect of the insanely high gas prices.

This one shouldn't be paywalled. BTW you can sometimes get around the paywalls by putting the appropriate search term into Google and reading it from their cache.

Google "CO2 producer restart operations UK minister strikes deal" and the first link should be the article with a paywall free token appended although it might ask you a question first.

They get the food grade CO2 as a byproduct of fertiliser manufacture. Then the CO2 is used for production of fizzy pop and stunning animals for slaughter.

It hasn't failed yet but there is every reason to expect a spectacular and catastrophic failure of UK infrastructure before too much longer.

We are stuck with a very dodgy conman as a Prime Minister who doesn't think any rules apply to him. His cabinet consists mostly of B-ark material so that his "Genius" may appear to shine all the brighter.

Think Trump light and you get the general idea. His position is now in danger over the No 10 Partygate affair with garden parties held during the first lockdown (no one told him it was against the rules!).

Even some Tory MPs have said that he should go. Government whips appear to have been blackmailing Tory MPs to back The Boris. That is now the subject of a police enquiry. (They are not called whips for nothing)

The government is retaliating by trying to defund the BBC. We live in interesting times. Electing a populist demagogue is a very bad idea!

I think there may still be one plant operating in Scotland still limping along but they would be better off shutting it down and just selling the electricity right now!

It seems to be still operating according to Scotland info:

The last really big Alcan one in England closed down a decade ago. Not economic to make aluminium with UK electricity. They were a victim of the 2008 financial crisis recession backwash (orders down >80%).

RTZ pulled the plug (literally). Steel making largely gone the same way.

Resistive heating is the baseline - it is 100% efficient, with all the electrical energy being turned into heat. Heat pumps do better - providing more heat energy where you want it (in the house) than the electrical energy in.

Resistive heating is used all the time, all over the world, for all kinds of heating applications.

That makes no sense. You can go from high temperature to low temperature with pretty close to perfect efficiency - it's the opposite direction that is inefficient.

There are no such things. (Have a little read-up on Carnot's law.)

You can certainly use waste heat from thermoelectric generation for domestic heating. There are limits to the efficiency, but you would get more total useful energy from the same source fuel. Whether that is worth the costs involved in making the infrastructure and transporting the heat from source to homes is another matter. In most places the power stations are far from where that water could be used, and by the time you have got the useful energy out of the water it is no longer that hot. Remember, you have to physically transport the water. How do you intend to get the waste water at, say, 80°C a distance of 10 km without losing more than about 15°C along the way?

Why would it ever have any impact on anything? Is the UK incapable of changing gears and buying CO2 from other countries? Maybe you need a channel pipeline to transport it? LOL

If it is deregulated no one is "running" it. Deregulation is fine as long as it's not a monopoly and there's no reason CF should have a monopoly. Didn't the UK travel the world establishing colonies? Now they are being mugged by a CO2 producer because the UK can't figure out how the ship in CO2? The world is laughing at this one!

Ah, it all makes sense now. CF is a US company. Most likely the groundwork for this started when Trmp was in office setting the tone of ripping off everyone and anyone.

Actually, I found an article about it and CF shut down production because the feedstock became expensive enough to make CO2 production unprofitable. I suppose CO2 prices had not risen. But if that is so, it means there are other sources of CO2 for the UK that are keeping the price down. Now this makes no sense at all. But here is the explanation, "The agreement with the company will last for three weeks whilst the CO2 market adapts to the global gas prices". So it is just a stop gap measure.

Who coined the phrase, "Much Ado About Nothing"? I should have known.

Except you didn't. You talked about "tariffs" and other nonsense which you simply made up.

Stop the BS now!

Sorry, I meant Martin Brown mentioned "tariffs", but you also created pure speculation which is nonsense.

I did some work on Moscow's hot water system, measuring the thermal energy in/out of a big site.

Moscow was interesting. Most apartment buildings were overheated and unmeasured. When it got too hot, people would open their windows.

And hence my statements are correct, and you read faster than you are able to comprehend.

The clown in charge in the UK has disconnected the country from the rest of the world. Yes, it should surely be possible to import CO₂ from other countries. But it would take them months to figure out the red tape involved and who should pay which tolls, tariffs or taxes. No European drivers will drive their trucks into the UK, and the UK doesn't have enough drivers to spare. And European suppliers would mostly be quite happy to let the UK suffer after the s***ty way the UK government has treated the rest of Europe.

The current government in the UK couldn't organise a piss-up in a brewery, and seem determined to screw up the country as much as possible while partying against the rules.

They can organise a piss up in Downing St, as their illegal parties demonstrate :(

Maybe we should lend them Trmp? Would that be an improvement? We certainly have no use for him, spare parts for an obsolete machine, eh?

Dear Dumbass, go ahead and name two brands of heatpumps that provide at least

100kBTU of heating capacity with outdoor temps of negative F. Be sure to hand over the name of the authorized installers within say 25 miles of or zip code 60601. Thanks. I'll give them a call and get some quotes.

Start with my challenge #1 and we'll work from there.

I'd wager this old clown can't even describe the refrigeration cycle without help from ask jeeves or a trip to the library.

Cleary the mold in your super-insulated house has rotted your brain.

That's standard fare for any large steam heat setup- let everyone roast and open the windows.

District heating is one this the commies have figured out. The mega heating plants in large Polish cities are fascinating.

In Chicago there are still some interesting district heating and cooling plants in downtown. The large schools and hospitals maintain their own and some still do cogeneration as well. Once the operation is large enough there's no reason to not extract ALL the energy in any form you can.

The difference between us and NYC is we have qualified engineers and maintenance people. The norm of steam blowing out of parking cones bolted to the streets in NYC is some third world nonsense only animals who can't figure out how to use dumpsters tolerate or accept.
