I used coal because the GP said they were in an area where coal and natural gas were primarily used for generation. Since coal is used as part of the blend, it seemed reasonable to consider it as a worst case scenario for efficiency. I was

Natural gas powered heat pumps actually exist, and are commercially available, although rare in North America. Most use an ammonia absorption cycle. Efficiency is lower than one might be hoping, quite a bit less than 2x. Here's a Ca

I downvoted you for your overconfidence. Your conclusion might be right, but it's not as straightforward as you suggest. You're right that the transmission losses aren't large, but you seem to be missing the much bigger los

There's a comment here from someone trying (probably unsuccessfully) to answer this same question: https://althouse.blogspot.com/2023/03/a-federal-official-wro... I can't find anything about this term wi

Meta: I noticed that the date near the top of the linked page (under the title) briefly flashes "Mar 24" before switching to "Mar 23". What's happening here?

Not quite true. The USDA regulates descriptions of all eggs packed with a "USDA grade shield" whether organic or not. Not all USDA graded eggs are cage-free, and not all cage-free eggs are graded by USDA. But, eggs packed under

Seems likely, so I unvouched and flagged it. Thanks!

I vouched for this to bring it back from being auto-dead, but I'm still not sure if it's a ChatGPT experiment or a new real user. It's a not a bad comment exactly, but it seems slightly off. Goldenpreppy8, can you speak for

I'd go farther: I thought it was a surprisingly good writeup for a general audience magazine! Northern Woodlands is interesting, partly because they take a somewhat pro-logging stance for what is essentially an environmentalist natur

I was guessing that the goal was to smear the lenses with something greasy, thereby reducing its ability to do long range surveillance. Jet fuel is essentially kerosene, which usually leaves a waxy residue. But maybe there's a better

Yes, this was obviously a deliberate attempt to disable or at least disrupt the drone. But the drone was almost certainly conducting surveillance to benefit Ukraine. As such, the Russian actions are not necessarily an act of war against the

I think this "friction" is really important to understand. For code of this sort, usually you figure out what assembly you want produced, and then you figure out the intrinsics necessary to produce this. In your mind, there is

I'm not sure of your familiarity, but I've worked with Daniel on several projects, and think you might be guessing wrong about his attitude toward warnings. He's not the sort who ignores warnings. His tendency is to change

I was tempted to give a similar answer, but I'm not so sure it's irrelevant. Yes, the windchill won't affect the energy efficiency of the heatpump. But it will affect the rate at which the house loses heat, and thus the BTU

Stray connections: A few years ago we renovated an old house in a nearby part of New York State. It involved cleaning out things left in the attic by the owner in the 1930's. Based on the clippings and memorabilia left behind, we de

Maybe this is a good place to ask. At 49:51 ( https://youtu.be/FLpGH0BpOnk?t=2991 ) there is a reference to a leaked British government email that discredits Bellingcat, saying they aren't ~"effective anymore becau

You might be misinterpreting. His nomenclature is misleading, but he doesn't mean "2x", he means "2X", where X is the number of companies. That is, you give 1 million € to 10 companies, and the one winner makes yo

As an American I tend to think of European and British police as being less violent, because they are frequently not carrying firearms, but their tactics with vehicles are often much more violent than would be allowed in the US. As an examp

You raise a good point, and are right that the linked article doesn't explicitly say this. And searching a bit, I didn't find any other clear claims about how these would be used. But is there actually some other way that would

Tomte's phrasing is confusing, but I don't think this is what he meant. I think he's accusing others of making comments with the intent of derailing stories, and not claiming that this is why he is posting such stories. His

I recently read an interesting chapter in a book from the 60's that seems relevant. The chapter is "Reactionary Aspects in Black Power", and it's in Julius Lester's book "Revolutionary Notes". Here'
