The US spent ~15000 USD per capita on healthcare in 2024, the highest number in the OECD. The second highest spending is in Switzerland at ~10000 USD per capita. So healthcare is ~50% more expensive in the US than in any other (rich) countr

Why would an article from 2019 be a counterargument to criticisms from 2022? Especially when the first sentence of that article is a prime example of Mearsheimers blind spot: that the Russians aren't actually realists, but instead are

European truck manufacturers like MAN and Scania have already had electric semi-trucks on the market for years. And they are selling, the Danish transport giant DSV alone has 400 driving around Europe.

The NATO 2% goal is quite a bit older than the Russian invasion of Crimea, dating back to at least the NATO summit in Riga in 2006. In any case ramping up our production of artillery shells and other munitions needed by Ukraine would defini

By increasing the return for other investors I'm increasing the cost of capital for the oil exploration companies. So: Yes, not buying shares in existing oil companies will (ever so marginally) decrease oil exploration.

Index funds are largely synonymous with passive, long term, buy-and-hold investors. That kind of investors are best served by slower changes to the index, especially since index funds are intended to piggy back on the price discovery that h

What if you try to go with the second option but the vendor barely puts any effort into getting the fix out to user and then it's a year later and the vulnerability is still under embargo? Maybe you decide that the next time you find a

Grandparent's report uses a nuclear LCOE of 110 USD/MWh which is pretty close to the Korean nuclear plant in Abu Dhabi. The (AFAIK) only plant they've built outside Korea. The French nuclear plants have an average capacity fa

My point was that the comparison with nuclear explosions is wonky, since we (in the world of that analogy) already have seen a tiny nuclear explosion 15 years ago. And we kept being told that explosions 100 times larger are just around the

Hydrogen has a volume problem, though. A 1st generation Toyota Mirai contains 5 kg of H2, equivalent to 197 kWh. That would take up 55 m3 at atmospheric pressure which is why the Mirai stores it at ~700 atmospheres. That's still a 78 l

In Haskell it's only ever one of (A(B)(C) or (B(A)(C), and you can tell which based on which characters B is made up of. If B starts with one of !#$%&*+./<=>?@\^|-~` it's the second situation, otherwise it's th

An AG corporation has stocks in order to track who owns how much and also attach different economic and voting rights to different classes of stock. The other way to incorporate a limited-liability company in Germany is the GmbH, which trac

Can you point to anywhere in INSAG-7 where they talk explicitly about that? Because if not your point about the show ignoring INSAG-7 falls a bit flat.

Sure, I'm just saying the power increase did happen, according to both INSAG-1 and INSAG-7. Neither INSAG-1, INSAG-7 nor Legasovs report claims there is a rapid increase in power before AZ-5 is pushed. The claim in INSAG-1 is that this

135% is quite low for an air source heat pump. For instance a Samsung HHSM-G600005-1 [0] claims to have been tested to be 485% efficient at heating water to 35°C and 283% efficient at heating water to 55°C, both with 7°C air temperature. Fo

No, natural gas _peakers_ don't need water for cooling, since they don't have steam turbines like combined cycle gas plants. Cooling is only necessary in thermal plants to condense the steam on the low-pressure side of the steam t

Land use per kWh is almost completely unimportant. Here in Denmark solar farms take up 0.09% of the land area and produce 7% of our electricity or ~2.5% of our energy use. That means 4% of our land area would be enough to cover all our ener

The fact that low-grade parasite-infections dampen autoimmune diseases isn't that big of a win. Presumably our immune system is as aggressive as it is in part due to the parasite-load our ancestors were exposed to.
