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.
