Average density for non-uniform objects is pretty useless, since the cubic volume scaling makes a mess of things. As an example, I pulled the stats for an electric locomotive. 19x3x4.4 meters, mass 90 metric tonnes. That's an average d

The new planned datacenters aren't near major population centers, so potential for district heating might be limited. Eyeballing from the map one of them is about has about 25 km from Oulu (pop 200k), and another is 30 km from Kajaani

I'm going to put in a good word for the SN100C / Sn100+ / SnCuNiGe lead-free solder. It's been my go-to for the past 8 years or so, and it flows almost as nicely as leaded.

Oh for Pete's sake, Sweden. Anything to avoid building more North-South connectivity. Sweden is currently split into four pricing areas due to lack of grid capacity. All the cheap electricity is typically in the north (hydro) and then

The Treedix cable tester is awesome. Ordered one after reading Terence Eden's positive review* and went through all my cables the day it arrived. My favorite was the cable with only the ground connected; went immediately into the bin.

Xanthan is the best if you need non-toxic slime for artistic purposes (e.g. Halloween decorations). Just make a stiff gel and hit it with a stick blender for desired consistency and lumpiness. This does introduce a lot of small air bubbles

"valuable asset for Europe", and it's available in 5 countries. Yay. We already have a bunch of local non-interoperable systems, so what's one more?

Sibelius was already in the last series of Finnish notes, so personally I'd pick Tove Jansson.

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

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 se

That's a bit unfair, since one of the achievements of Gustavus Adolphus was establishing governing institutions and professional bureucracy. The bigger issue with that plan was be that the king was off fighting a war in Poland.

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,

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 s

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 heatpum

Not yet, the Microsoft center is still in planning/construction. But up north there's at least one city (Kajaani) on data center heat; details in another comment.

Nice! Apparently the local supercomputer cluster in Kajaani has also been hooked up in 2021 and is responsible for a fifth of heating.

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

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 p

The electricity can flow both ways in a cable, and for example right now Denmark is exporting to most of its neighbours. https://www.svk.se/om-kraftsystemet/kontrollrummet/ is a wonderful resource

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. For about two seconds before I cut the power.
