Looks like 80% of firefighters (or rescue personnel according to modern naming) in Finland are members of volunteer fire brigades or so-called contract fire brigades and they respond to nearly half of the total emergencies but over 90% of emergencies outside densely populated areas.

Well, maybe there's enough prototype production for motor cycles.

Wind in practice. There's only few hours of sunlight in the winter during the day. There has been a surge of electric boiler buildup by district heating companies in the last few years to exploit the periods of high wind and resulting very low electricity prices.

Heat is transferred using disctrict heating networks where 65-120 C water is circulated.

Several cities in Finland have water based thermal batteries already, connected to local district heating networks. They have been previously used to store energy from existing combined heat and power plants, but now that wind power build up has created a lot of excess cheap power period, have been modified to include electric boilers.

You can also build the datacenters somewhere where there is plenty of carbon free energy available. Google has just recently bought two plots in Northern Finland, near some serious grid connections, and they're not the only one with plans.

Finland can build and has been building a lot of wind power lately since it's flat and quite sparsely populated but with relatively good infrastructure. There are lot of projects in the planning pipelines just waiting for demand. Electricity prices are among the lowest in Europe already.

I don't think Nordics will be needing much batteries, Norway and Sweden have so much hydropower that can absorb fluctuations in the power production and usage. But there still will be a lot installed alongside new renewable sites, you can use them to optimize the grid connections.

Finnish energy company ST1 tried to make a deep heat district heating plant and drilled few over 6km deep wells. They wanted to connect the wells at the bottom but failed to get enough water flowing between wells for profitable operation.

TIL that networkd has built-in DHCP server. I don't think that this matters here, using networkd for client configuration shouldn't prevent using something else for server.

Entire police force of Finland (~7300) is only about fifth of NYPD (~33000 officers), but they have over 10 times more drones, more than 330.

At least here in northern Finland you could already do that even with staff present. Everyone goes in with backpacks or bags and with self service there's no way to actually monitor if all the books were properly checked out.

anttisalmela — Thu, 09 Nov 2023 06:35:05 +0000

It's not uncommon in Nordics to have satellite libraries with mainly self service hours where there's no staff present but you need to swipe / scan your library card to get in.

Consumers in Finland (and as far as I know, in other Nordics too) can get Nordpool spot priced electricity contracts, doesn't really get truly negative since you need to pay margin, taxes and transfer anyway.

Last year, 2000 MW of wind power was built, at the end of the year total power was 5200 MW. Olkiluoto 3 nuclear reactor was brought online, 1600MW. Solar power nearly doubled, from 358 MW to 606 MW. So far this year 500MW of wind power and 100MW of solar has been added to the grid.

Queries for grid connections pass already 100GW. Over twenty electrolysis plants are in planning.

I live above latitude 65 degrees so auroras are quite common. Few years ago I had to deliberately go out and seek location without light pollution and watch auroras because I wasn't sure anymore if I had actually seen them live.

Now I atleast remember the delighted screams of tourists that were taking photos there.

The bubble that knows about this ban so far is relatively small. Will it reach the advertisers at all?

Edit: my bubble was too limited.
