I don't really see why Finland would be unable to scale production though? Expensive workforce? Surely that could be worked around, Sweden still produces semis and have similarly costly workforce. What other impediments do they even face?

because building things in Europe requires complying with a myriad laws and regulations.

Not sure why you’re being downvoted, this is objectively true.

Saying this as a German, where the economy is the worst it’s been in decades and our federal government acts incapable at changing this so far.

Anyone who’s been to China, Israel or the US will be familiar with the pragmatism and, more importantly speed things happen in these places.

I do like Europes rules on civil liberty and privacy protections, but let’s not pretend the bureaucracy is on a unique scale across the board.

Jif creamy peanut butter comes in at 190 kcal per 33 g serving [0], and 2000 kcal is 2.32 kW-h. Doing some good old fashioned dimensional analysis, the energy density of store-bought PB is

  190 kcal |   2.32 kw | 1000 g
  ---------+-----------+------- = 6.68 kW-h/kg
      33 g | 2000 kcal | kg
So, Jif creamy is nearly 17 times as energy dense as Donut's battery. Even so, crunchy is better.

Eh. There are at least a half dozen other companies with working solid state batteries outside China like Rimac in Estonia (with ProLogium in Taiwan and Mitsubishi), Solid Power in Colorado (with Samsung SDI) and QuantumScape in California (with VW's PowerCo SE). Mass manufacturing them is the big issue.

Rimac in Croatia!

My mistake! You're absolutely right. Rimac is in Croatia.

Right, but a jar of peanut butter is more comparable to a gas can than to a solid-stste battery. I'm sure if you measured 100% of the kcal comprising the battery in a bomb calorimeter, the source of measurements of the kcal of food, you'd end up with a significantly higher density - but wholesale combustion is the paradigm we're trying to move past, not towards.

If this is true, it's possible that the technology is from Nordic Nano. That would at least explain how a motor/software company could pull a battery out of thin air: https://www.donutlab.com/nordic-nano-investment/ Their chief scientist is working on solar-powered hydrogen production, which seems fairly unrelated to solid state batteries: https://www.nordicnano.co/chief-scientist-bela-bhuskute-will...

Rolling coal is rude an obnoxious but doesn't "destroy" anything. I think you are projecting something personal against the stereotype guy that does that. Just like someone who was bullied might irrationally hate tough looking bikers. Some men (and women!) like large and overpowered trucks. You don't have to like them, but you should praise the freedom that this country gives us to choose our own pursuits.

Rolling coal is cumulatively destructive to the local environment and to the health of the people in the area in the more general sense, and in cases where truck drivers do it to cyclists and hybrid/EV drivers directly and immediately harmful to their health.

If nothing else, rolling coal with the intent of placing somebody within the plume should be considered assault. Diesel fumes/soot is some nasty stuff.

driving any ICE vehicle is cumulatively destructive. It's not any worse just because you can see carbon particles vs clear exhaust.

Yeah surely rolling coal and SULEV are exactly the same. Never mind the fact that the other one is literally specced to produce less than 10% of the average emissions, surely they are the same.
