Nordjyske jernbaner har gjort det gratis at have cykel med i toget. Det har gjort at jeg bruger min cykel væsentligt mere end før.

Don't get me wrong, I hope it does, but realistically the EU will likely just ignore the petition by giving a quick no vote and continue with their lives.

What a lovely accident.

I am 100% expecting them to have learned absolutely fuck all from 2042, and instead double down on what they THINK people want. A hero fps "I am always the main character" game.

In reality they can never compete with stuff like Fortnite or CoD, because EA has no fucking idea who their customers really are, and they'll never care to figure it out.

Every single one of my Samsung appliances work great. Most notably my washing machine and dryer. Never had a single hickup in the ~6 years I've had them. A lot of the time people have issues with stuff, is because they don't take care of their machine, and expect an appliance will run reliably for 10+ years with 0 maintenance. They don't.

99/100 times user error is the answer to most stuff. Users are idiots who will not accept responsibility as long as they can say "well it's the appliance that is built bad".

Because of innovation.

Let's say we make 4 standard sizes today. Type A (25kwh), Type B (50kwh), Type C (75kwh) and Type D (100kwh). These 4 different batteries have different sizes, because energydensity and all that.

In 3 years some company finds a much better way to store electricity. Now they can pack 50kwh into a 25 kwh pack (with the same linear progression through the other types. So now you'd need a Type A1 and Type A2, Type B1 and Type B2.... and so forth. Now you have 8 different kinds.

Sure you could just reuse the obsolete batteries for something else, or strip them down to their materials and use those, but that would be so incredibly wasteful in energy, that the green option, would be to offer both. That way someone who only needs a type B1 for their commute, can save a bit of money, while the company isn't forced to replace all the batteries. But now you have a shitload of different batteries in your storage.

In 3 years time some new company have made an even better battery. The batteries should be able to function for more than 6-ish years, in fact, many places have warrenties for 10+ years, so just determining that they're done and needs replacing isn't a viable option at this point. So now you need 12 different kinds of batteries.

Sure you may not need as many of each battery with each new generation, but you're still going to need an excess of what you expect to have to need. Otherwise your customers will choose your competitor when you run out of their particular battery.

But the absolute biggest issue is. How many batteries would you need in a city like Tokyo at a single battery swapping station? 100 isn't going to do it, 1000 is probably more realistic. How do you store 1000 batteries in a city like Tokyo? Buy a skyscraper, knock it down and build a storage building? You'll be half a billion in dept from the start and won't break even in your lifetime.

In short. Swappable batteries is an attempt to overengineer a problem that has an insanely simple solution. Patience. Who knows, maybe in 20 years you'll be able to charge 50kwh in 5 minutes anyway?

Biggest problem I see with this is storage. A Fiat Punto sized car will need a smaller battery than a Peugeot 5008. Even if a place like the EU were to force standised tech to make Peugeot batteries to be interchangable with VW or BYD, the amount of different batteries due to car size will make swappable batteries require a rediculous amount of storage space. So how do you get that kind of space in the middle of London? Or Tokyo?

I think just growing a patience and planning when and where to charge is a much more efficient way of going about it.

Charge while you're shopping, or while the car is parked at your job, or while you're picking up the kids from school.

And really all it took to debunk it was my 6 year old self after having heard it (from a teacher none the less), and putting sweet food on the spot that could supposedly only sense sour stuff.

How this myth has ever spread is beyond me...

Just tried this with ChatGPT, stupid thing doesn't think rabbits and cows lay eggs. Instead it started talking about the sizes of egg cells in mammals.

A lot of those problems is 100% fixable through the settings menu...

While you're waiting, innocent people are going to die. Your inaction is actively aiding the fascists.
