Oh I think I know what you’re talking about, abusing a minisplit by idling the inverter back too far. Effectively you have a hugely oversized condenser for the tiny flow, under the right conditions like a cool night you can get ridiculous subcooling.

But COP is irrelevant in this case because you’ve derated the actual BTU to near zero, you aren’t moving any refrigerant.

Also yes this will kill your compressor because the minimum speed is set where it will get enough oil flow. Run it too slow, and it won’t pick up oil and eventually seize up. You also could end up running the suction in vacuum which is also hard on compressors.

Actually come to think of it, I don’t think Pert is actually gendered. But everyone knows it’s a “man’s shampoo”, because it isn’t actively marketed as a “women’s shampoo”… Yeah, pretty stupid, isn’t it.

I saw 5 for air-air and was impressed. Then I see SCOP? Oh please. Why not change the scale again to make sure nobody knows what a good value is. Just like SEER on an air conditioner.

SCOP varies depending on environmental conditions!

Real COP or go home IMO. Watts out/watts in, no fudging numbers to confuse consumers again.

I designed my heating system around a fairly efficient non-condensing NG boiler that takes 40W for the fan. I can run it and the circulators off my battery bank no problem, and handle a sustained power failure. But only because of the natural gas.

I’ve been integrating a water-water GSHP into it to provide summer cooling and a supplemental heat source from my solar panels. It works well, but in my climate (Rural Canada) I would be insane to completely remove my gas boiler IMO. Heating demand is just way too high on the sort of days where the power goes out. I’ve been working on plans for a wood boiler but insurance has put their foot right down on anything that burns wood in the last couple years.

Here in Canada we can’t get lithium at a reasonable price so I have 10kWh of lead-acid (which as you know is actually 5). Doesn’t go very far on a cold winter day with 4 hours of sun and snow on the panels!

On the upside I haven’t had to hook my generator to my house in years, I’m really happy with my “grid-independent” system.

Double would be a COP of over 10. That’s a stretch for an overbuilt GSHP and not even slightly feasible for air-air.

High COPs are usually easy on a compressor as they represent low compression ratios and low differential temps. For example I can hit around COP 7 in cooling on my scrap heap GSHP, with an evap temp around 10C and condenser temp around 20C. That’s a high side pressure around 100 psi and only 30 psi of differential, “barely working” as far as the compressor is concerned.

The only way I know to get high COPs is to have an oversized condenser and a way to get your refrigerant below ambient, like evaporative, ground source or overnight radiant so you can get the compression ratio down, unless you know a secret in which case I’m not afraid to burn out a compressor or two trying it out!

If the man gets his hair really dirty, like farm dirty with diesel and moly grease and itchy chaff bits, then it means it probably doesn’t have what it takes to do the job.

My wife bought endless shampoos, I tried them for sport and none ever impressed me. Our hard water laughs at fancy shampoos and soaps.

I always told her to forget it and use my big jug of Pert. A classic that says something on the back like “Pert wasn’t designed to waste your time and money. Pert was designed to get your hair clean” but she was sure there was something wrong with it because it was only 5 bucks.

Finally one day she gave it a try and has used Pert ever since. It made her hair smooth and soft, it even washes moly grease out and it smells “fine”, men’s shampoo is the winner IMO

And now my shower is so tidy with only one jug of shampoo

Out here in hard water country we just call that “Dove”

Seriously if you’re looking for a soap that just plain works in ANY water and doesn’t leave your skin feeling like it shrank a size, a good old bar of Dove is the answer.

It had better at least be blue.

Lol, jokes on us they’re all blue, cobalt or not

Great to hear this story of success. That plus

$266.99 per probe for the original proprietary one

Reminds me of Schneider’s stupid proprietary dongle for programming their PLCs. It’s just a CH341 in a funny shaped case that fits into the funny shaped slot on the PLC, where it plugs onto an ordinary 0.1" pin header to talk logic level serial.

Plus it has a custom USB ID of course. Probably costs $2 to manufacture, sells for almost $300 as well.

what’s the purpose of holding the most important job in the world, if you constantly have to worry about going to prison? Ridiculous.

Big yikes there. The purpose is to serve the American people.

The President is not the King of America, and its easy to not have to worry about going to prison - just don’t commit crimes. Before Trump, the question wasn’t even relevant.

The interesting thing to me regarding both power and blasphemy is that by the fact that it was on display in a major cathedral, those in charge have already given it their blessing. Anyone calling “blasphemy” only looks like a fool.

So you have these “traditionalists” wanting to drag the Church backwards. But due to the hierarchical structure of the Catholic Church that’s just not how it works. Church leadership has made significant progressive strides over the last decade, leaving people like this Tschugguel with only impotent rage and vandalism as their options. And as you state this only adds new context to the art, giving it more power and ensuring that their regressive goals are not taken seriously.

Meanwhile the Evangelicals have gone absolute nutters, I never thought I would see the day where the Catholics were the “progressive” church. But they play the long game, and have always changed along with society over the millenia.

Interesting to see the charts there showing a steady 25% against. Even when asked if a majority government should have the support of a majority of voters!

Who are these guys! Its hard to believe that a quarter of people surveyed appear to not want our democracy to function.

The work had drawn criticism from some Catholics, who said it was blasphemous.

I won’t deny it’s kind of an odd idea for a sculpture and clearly designed to create controversy, but claiming that it’s blasphemous just confirms the fact that they don’t know the definition of the word. It just depicts a defining moment in Christian history, whether you like the aesthetics or not… The Catholic church has definitely celebrated weirder things.

I don’t see how people like you miss the entire concept of “base load”.

I live in a region with vast amounts of renewable energy resources. It’s always windy and the sun shines almost every day. I have solar panels on my house that cover most of my DHW and a large fraction of my summer cooling load, and keep most of my appliances running.

But right now, the sun is down and the wind is flat. And I still need power. My battery storage would be depleted by morning, damaging it through overdischarge if I don’t buy power from the grid instead.

And it’s a lovely summer evening with no heating or cooling demand! What about midwinter, -35C and dark and snowy? Where is my power coming from on that day, after a month of days just like it?

Nuclear.

Sure lasers don’t have recoil, but I see no reason a laser gun can’t have recoil.

Anything from flywheel energy storage, a lasing medium compressed by pistons, massive magnetic fields created by high currents, who knows what’s inside that thing.

A handheld laser gun has to generate a beam of such unrealistic intensity that I’d be surprised if the power stage didn’t buck in some manner.

Straight into the toaster from the freezer. If you want bread, set the toaster light. If you want toast, set it dark.

Some toasters even have a switch for frozen bread to compensate.

Here in rural Canada we have always frozen bread even short term. Mostly because mice can’t get into the freezer.

Thanks for the American context as I’m a Canadian and our systems are different here. I didn’t realize the risks involved and the motivation behind it. I think this might be my least popular comment on Lemmy ever😅

The USA as a battleground between religion and atheism changes the context as I would shrug most of this off here in Canada as harmless. Like the 10 commandments? Most of them are good advice, basically just “don’t be a piece of shit” and i wouldn’t have a problem teaching them to kids… Unless the goal is to teach them actively as the word of God and marginalize non-believers as sinful, in which case this is absolutely criminal. That is church, not school.

We have a more robust separation of church and state to the point where when I read “teaching the Bible in school” I hear “robustly secular, historical and cultural study” which as I stated I believe would be a valuable learning experience. In Quebec there are even rules that public servants can’t display any religious symbols at all, even as small as a cross on a bracelet. The leader of our Conservative party recently made a statement that both abortion and gay rights were “a closed issue” and he would not stand for any attacks on them.

So personally my wife and I made the hard decision this year to send our daughter to a Catholic school next year due to the rapidly declining quality of public education. However the Catholic school district here is publicly funded and staffed, with strict regulations that any religious content is optional and that respect must be given equally to those who choose it or do not choose it.

Many of her friends have already made the switch (regular school is quickly emptying out of smart kids and turning into a zoo as parents pull their kids) and stated this is exactly how it works, most of them being non-religious as well but impressed with the discipline and learning outcomes. My wife teaches college and said the difference is night and day with some kids even making it out of public highschool unable to read. Meanwhile my daughter’s new school has won awards for the achievements of its graduates and their placement in top schools and in industry.

So you see I’m comfortable enough with our dedication to secularism here in Canada that I am willing to send my daughter to an actual Catholic school with no fear that she will be brainwashed… Obviously a bit of bible study doesn’t scare me but in the context of the USA culture war it’s clearly a much bigger deal.

Deere makes good equipment but you won’t find one piece of it on my farm. Fuck em

Looks like I’m gonna run my Mercedes 300D until it literally collapses into a heap. The engine is supposed to be good for a million miles, after that I guess I can change bearing journals, valves and seats, bore it out and do oversize pistons like they did back in the day.

I’m appreciating more and more owning a car that only has an electrical system for the lights and radio

No I’m serious, I’m here in SK and we’re trying to push Moe and his cronies out for the NDP this fall, and our biggest problem is the federal NDP damaging the brand by backing Trudeau. All we say all day is “The SK NDP is not affiliated with the federal party, we stand for working Canadians, vote Moe out”

If you think $500 for low income and seniors is anything other than a bone thrown to pacify the poor then Singh has pulled the wool over your eyes.

The requirement for “no access to insurance” absolutely torpedoes the entire thing. Private insurers need to fall, universal coverage is the only way. Dental is the Canadian equivalent to the entire USA health insurance racket.

Congrats on living in the one green riding, which does give you some power over your single seat party… Which ultimately holds no power at all in our broken system.

I’m sorry to say I voted Trudeau on the promise of electoral reform, which he then told us we didn’t want. I’m in a safe blue riding which means my vote is pointless, so I’m going full protest vote next time for the PPC 🤣 Max is laughable, especially his obsession with dairy supply management, but enough votes for “burn it down” will hopefully send a message.
