Seconds later, he continued, “Doc Ronny Johnson. Does everyone know Ronny Johnson, congressman from Texas? He was the White House doctor, and he said I was the healthiest president, he feels, in history, so I liked him very much indeed immediately."

All of this would be the funniest shit ever if it wasn’t so dangerous to world politics.

I wish it was only useless:(

They are 100% aware

Shit is weird, it was completely offline for a day or two but now I’ve been able to access it via app again for a couple of days, I can even post this from feddit.de. Meanwhile in the browser it appears entirely dead. As if the Lemmy instance is working again but the Apache is down.

Our cities are too old to be build with cars in mind.

Vast parts of the cities I lived in were completely bulldozed to accommodate cars.

Loads of people love to pretend an NPP is just a hut with a magic gem inside delivering an endless amount of power for free. In reality they are huge, highly complex, high-security facilities that take decades and billions to build and need to be operated and maintained by loads of highly trained staff in 24/7 shift operations. This isn’t to downplay their merit of providing CO2 emission free power, but for the love of god please appreciate the enormous effort and expense this is achieved with, especially when comparing it to renewables.

gas furnance that was somehow under-dimensioned – the idea is that in the real cold days you’d still have the good ole fireplace

Oddly enough I’ve never encountered that in Germany, I only ever see catastrophically oversized furnaces that start cycling in March… Seems to me plumbers never really worry too much about correct dimensioning, they just put the same 20 kW furnace that they know and love to install in every apartment and single family home. For some it will be somewhat adequate, for some it’ll be oversized, who cares, customers never complain when the furnace cycles, but when it’s too cold, you’ve got a problem. Same as they’re never too worried about finding suitable supply water temps. Just set it to 80 and you’re good, it’s the customer who pays horrendous gas bills, not you lmao. That’s also why everyone thinks their Altbau has to have 80°+ supply water when they have never really tried anything lower to see if it maybe suffices. My parents had their oil-furnace on 80C supply for the past 40 years and last winter when everybody was trying to save as much energy as possible they figured out you can set it to 55 as well.

but assuming they’re saying that it’s saying that $0.63 worth of natural gas gives you the equivalent thermal output of 1kWh

Correct (although $0.063), and interesting to see you seem unfamiliar with this, this is the standard way of listing energy prices in Europe, it’s not just that site. That site was just my first hit when I looked up Canadian energy prices. It’s the low heat value and it’s determined by the energy in a fuel if not allowed to condense (which is the relevant value for a traditional furnace, if you have a more modern condensing furnace you take the high heat value) and it makes it relatively easy to compare different sources of energy.

Canada is huge, and some of that landmass is in the Arctic circle.

What people never realise is that being far up in arctic climates doesn’t only impair an SCOP. Yeah the lowest temps are very cold, but that means temporarily bad COPs. An SCOP is made up of the whole heating period though, which in colder climates is longer, so in turn you have several months more of the time where heat pumps are extremely viable with temporary COPs above 5 or 6 saving loads of energy. The real problem is if your lowest temps are so low that a heat pump will stop working entirely, in which case you get a hybrid system or just leave your old furnace in as backup, which is even better for your SCOP because you omit the month(s) with the worst COP and only use the heat pump when it’s most viable. Let’s say you live in Tuktoyaktuk and heating period is basically all year, then you have your furnace on for 3-4 months but you’re saving massive amounts of energy with your heat pump in the other 8-9 months of the year.

touching on the nuances of the word “efficiency”

I actually tend to avoid using that term for heat pumps anyway, as it’s not really correct in terms of physics. What makes heat pumps so viable is a coefficient of performance, their actual electrical efficiency isn’t all that good at 50-60%, but it’s also kinda irrelevant. It’s sometimes easier to just call it efficiency, but like you say, once you go into the nitty gritty it falls apart.

if your energy cost for that source of power is high, it’s going to lose the financial argument every time.

How high, is the question. How much more is electricity where you live that heat pumps “lose the financial argument every time”? Where I’m from a kWh of electricity is roughly 2.8-3x that of natural gas, so most modern heat pumps will beat that, some by quite a margin.

If globalpetrolprices.com is to be trusted and Canadian natural gas is 0.063 CAD and electricity is 0.165 CAD you’re very much in the same boat with a 2.6 ratio. Most heat pumps should be able to beat a 2.6 SCOP even in Canada.

So, sure, the study only looks at COPs and not at overall cost, but I think it’s not unreasonable to expect home owners to be able to divide electricity price by gas price and compare it to the SCOP of heat pumps on offer.

You’d usually run two or more units in a cascade/multiplex when requiring large amounts of power rather than having one giant unit. Means you can turn off one or more units entirely for low heating demand.

Too cold, too cold…

In Germany this will likely still be a controversial take in 2026. Our political right managed to shift this debate into ideology territory and a good chunk of people believe heat pumps are environmentalists’ fever dreams that don’t really work in cold Germany.

A split system AC is a heat pump in any context. So is a refrigerator. They’re all the same technology that move energy via a refrigerant’s latent heat by compressing it into a warm part and letting it expand into a cold part.

I hear that too. Not just politicians, there’s loads of experts lecturing on heating technologies. It’s just too cold in Germany for heat pumps. Doesn’t stop Scandinavia from getting them, granted, but in Germany it’s just too cold. No point. Sorry.

The little lithium deposit that could

While y’all here:

is there a terminal emulator that has “modern” text entry controls while still having tab completion? Like selecting text by going shift+leftarrow or deleting whole words by holding ctrl+backspace/del or replacing whole words that are selected while pasting text rather than it pasting at the point where the curser is at the start of selected text so you still have to manually delete the original characters. Maybe Undo, redo with ctrl (shift) z…

Stuff like that. Just wondering. I always find it very cumbersome to fiddle with long commands especially if they contain long paths that you want to modify. Lots of backspace and arrow-keys hitting for every single character…
