No, the 70% for EVs is in real world conditions. The 30% for hydrogen is in ideal conditions, it’s usually around 10% in real life conditions right now.
And the efficiency of EVs doesn’t decrease that much at temperature increases or decreases, especially not down to the efficiency that hydrogen has right now.
This video is sadly only in German, but the guy who made it is a researcher for hydrogen and batteries (he knows what he is talking about), he explains it very well, why hydrogen will never work for cars: youtu.be/ZXC33UjdtBU?si=zHfORdzj0bfSesrS
Hydrogen might be clean if it is produced from renewable energies, but we don’t even have enough renewables to cover our current consumption, much less 3 times as much to cover everyone using hydrogen, and I don’t know what you mean by abundant, of course it is around everywhere bound in water, but we can’t use it before splitting it, which needs those insane amounts of energy.
There are also no projects that are able to go above those 30% because it’s just not possible, we can’t break the laws of physics.
We get new battery advancements every year, the current Trend is replacing everything with LiFePo4 batteries that are almost as good as LiNMnC batteries, because they need much less rare materials. Those batteries weren’t good enough a few years ago to be used in cars.
In the End electric cars are already good enough for almost all use cases and cost competitive, factoring in the running costs, while almost all car manufacturers have given up on hydrogen because they made losses even with their very expensive hydrogen cars.
I am seeing you being part of the “fusion is almost here” crowd, EVs don’t need to improve anymore to be competitive, but they most likely will, considering that the market for EVs is pretty big nowadays.

It is literally physically impossible to increase the efficiency of electricity-> hydrogen -> electricity above 30%, and that’s if everything is perfect.
EVs are above 70% efficient in the real world btw.
Hydrogen will be useful to decarbonise some parts of heavy industry where electricity cannot be directly used, but that’s about it.
There is a reason why fossil fuel industries are pushing hydrogen, because it means that the car makers can keep selling combustion cars until hydrogen is ready, which it never will be.
And even if hydrogen cars were somewhat ready in 10 years, EVs and the charging stations would also be much better than they are now.
And hydrogen has such a low density that a tanker truck could only carry hydrogen for around 100 car refills, compared to 600-900 that a normal tanker truck does. So every gas station would have to be connected to a hydrogen pipeline, which will realistically never happen.

If I want to be able to access my trunk easily I will have to go forwards.
Otherwise I always go backwards.

Here in Germany the forum culture is still somewhat alive, social media did take a big cut though.

Except Steam never deletes games that you already own or takes them away from you for other reasons.
Yes, they could do that in the future but its the one company where that is unlikely.

Holy shit, 300mg caffeine sounds insane to me (a German). Over here Energy Drinks are not allowed to contain more than 32mg caffeine/100ml. So a big can (500ml) would have 160ml. Those are already a bit too much for me, I can only imagine how 300mg would feel.

Hey that is my name, it doesnt have to be associated with the idiot Elon.

Welp, I have only now seen this post on the 19.09.2024.
I guess I did not only miss the notification, but also the rapture itself.
- Comment on Decentralised YouTube alternative Odysee no longer serving ads 5 months ago:
It also breaks the flow of the video, which is why I have started skipping them. I noticed just how much nicer videos without any sponsorships are because you dont have to dedicate time to lead into and out of an ad and can continue the video without explaining everything twice.
I also dont see any value gained by me or the creator if I fully watch the 100th squarespace commercial, as I dont get to hear anything new.
But the most egregious videos are where they try to hide that they are transitioning into an ad, like by creating some minute long argument that leads from the topic to the sponsor. Which leads to me not only having wasted my time for the actual ad, but also the transition.

You can also run the Network Controller on any PC or even Home Assistant if you dont need to do any advanced traffic routing features.

Temper proof torx makes me lol, because almost every bit set I own includes them.
If you break it off you will most likely leave some behind, which will significantly reduce the mating area because you cannot insert the bit fully and may lead to stripping the screw.
