I'm in the EU and you absolutely can put a French building on a banknote. I'd much rather look at the Eiffel tower or the Tower of Pisa or Neuschwanstein castle than the European Court of Auditors.
Or if you like to have something modern, Paimio Sanatorium or Turning Torso.
The conjecture assumes durable goods, so it doesn't apply to medicine. Also no resale, so that narrows the scope even more.
The gist of the conjecture is that if the customers can wait out for price drops and the monopolist wants to sell their thing, then after a few rounds of "he knows that we know that..." the price ends up to be the marginal cost.
Now, real world disagrees with the model, so next steps are to examine why this happens and maybe discover some new economic interaction.
EU has Aisler but what you win in shipping times you lose in production lead time (unless you pay for faster service).
And there are probably others but with even less visibility / willingness to interact with private customers. Hell, I used to live next door to a sales office for a local PCB fab, but they never bothered to answer my inquiry about prototypes.
(That's another thing the proto-friendly companies do right: instant quotes without log-in requirement)
My personal experience is like getting eye glasses for your appetite. Easier to eat reasonably sized portions and they're nutritionally well-balanced.
Also the late night cravings are more specific: instead of vague "need to eat something", it's "I'd love a tomato" or "mmm yogurt" or "actually a load of carbs would hit the spot".
55 C might be enough to heat buildings but it's right on the edge where domestic hot water needs to be to kill Legionella. So traditional DH systems need to run hotter.
There low-temp/cold DH systems out there that rely on heatpumps in the buildings to extract the heat. Less losses in the network and you can even use them for cooling, but needs heat pumps everywhere.
In comparison, a traditional heat exhanger is pretty simple technology; just a hunk of metal with a valve.
Microsoft's already building data centers hooked up to district heating (Espoo and Kirkkonummi, Finland). Heatpumps are amazing.
(Seasonal heat storage is also a thing, Espoo's neighbours have tens of GWh of storage, with a new 90 GWh cavern in the works. Not sure if the systems are interlinked.)
And then there are us engineers. I don't care much either way whether Maxwell's equations are ∇F = J or some other form, as long as it makes the problem easier to solve.
If I were in the GA Marketing Committee I'd publish a paper with suitably hand-picked worked examples where the vector approach is long and tedious, and GA version is short and sweet.
They're not great for anything that might produce heat. Seeing a MOSFET slowly starting to imitate the Tower of Pisa after dissipating a measly 1 W for a few moments was a sight to behold.
One of these years I'm going to make a Finnish programming language that enforces the correct case in arguments. And I don't mean silly arguments like camelCase vs kebab-case, I mean grammar.
Some examples to illustrate:
tiedosto on "foo.txt" avattuna
tulostin on PRN1
kirjoita(tiedostoon, "a")
kirjoita(tulostimelle, "b")
If there were one. The closest thing is the Treaty of Lisbon, which in turn was an update on the Treaties of Maastricht and Rome.
However, the matter has been heard in the European Court of Justice in 2002, and the short version is "Community law does not preclude compulsory military service being reserved to men."
