There's several projects ongoing to store heat from district heating systems, for example in Västerås [1] and Linköping [2]

Vattenfall is fully state-owned anyway.


Vattenfall invested heavily (hugely) in German brown coal, then shelved it. Swedish tax payers effectively accelerating German energy off brown coal. In the greater scheme of things, not sure what to think of it, but as an investment, it was pretty bad.


Yeah they also invested in Dutch natural gas which was a catastropic deal.

I think the relationship between the government and Vattenfall is heavily regulated so that they can't micromanage and have to set high profit goals for the company. It is probably required so that it does not interfere with market economy.


Articles at the time seem to disagree about the "without political oversight" part, focusing on the political nature of the decision:

They might have invested in nuclear if they didn't buy coal, couldn't have that.

Also, I think the largest cash deal in Swedish history is something that is just moving along together with the new coffee machine for the lobby, without political oversight.

The decision also went by the prime minister, although he at first disputed it:

More or less the premise of this 2021 article: https://www.thedrive.com/the-war-zone/40054/adversary-drones...


Amazon creates their own security chips since several years with the Nitro system: https://aws.amazon.com/ec2/nitro/


The reasoning they don't need to build anything in their servers that's not needed still stands. It doesn't make sense if you need just a few units of a given type, but hyperscalers, who deploy computers by the acre, any unused SAS connector is dead weight.


Normally these ageeements are time limited to say 1-3 years and then needs to be renegotiated, this is when union requires some certain salary increases over the next agreement period and for that promise to not strike given that the employer hold up the agreement. Should the not come to a agreement during the negotiations, strikes are an option.


Found a quite good article about differences on the helmets (and some other firefighting techniques like fognails) in https://www.firehouse.com/safety-health/ppe/helmets/article/...

This fognail video was quite interesting also https://www.youtube.com/watch?v=Oe_V7aLyzM8


Immobilizers are mandatory in EU since 1998, so yes.


Gas stations charge for air?


Does your place of business have an air compressor outside, an air hose and fittings for the public to use for free?


Yeah, more or less every manned gas station in Sweden has that.


No, I meant non gas station providing air for free... Since we're on the topic of businesses giving free services only tangentially related to what they sell.


I guess one example is bikeshops providing air for bikes for free. But I agree, not many services provide things for free. I’m assuming gas stations see it as a way to draw in customers, many also have bathrooms for free.


Yes it’s common to have a timed payment machine for air. Usually dual purpose with a vacuum machine as well.


Interesting, here in Sweden air is always free, however vaccums cost money (but way less stations have vaccums).


The eu-north-1 AZ’s are in Västerås, Eskilstuna and Katrineholm, all ~100 km from Stockholm and ~40-80 km from each other.
