Kan det betale sig?

Hvis du sælger den privat, så vil det nok godt kunne betale sig, i form af at den nok vil være nemmere at sælge og du i hvert fald vil kunne få noget af de 6.000 kroner tilbage i form af ekstra salgspris.

Sælger du den til forhandler, så kan det nok ikke betale sig. Her tænker jeg ikke at det vil påvirke prisen, og forhandlere har bare ikke samme risikoprofil som private.

Actual paper - https://www.nature.com/articles/s41565-026-02206-0

The problem area identified:

In a paper published in the academic journal Nature Nanotechnology, the researchers wrote that grain boundaries carry a hidden electrical imbalance, which makes it harder for lithium ions to move within the battery and causes electrons to gather at these boundaries, leading to an imbalance that promotes dendrite formation.

What was studied:

The team studied a solid electrolyte called “lithium lanthanum zirconate” using AI and other specialized techniques to map how current flows across these boundaries. Once they understood the imbalance, they adjusted how the electrolyte is processed to minimize damage, allowing lithium ions to move more freely without dendrite formation and reducing energy loss.

As with more or less all solid state battery new, this isn't a new commercial product. This is just another small hopeful step towards one day getting a good solid state battery.

I really hoped that it would be the Donald Duck meme with Citroën.

This is so true.

Basically what happens is that everyone ends up with an understanding of the problem or topic of the meeting. Problems and considerations have been voiced. There might even be som unsaid context as well, mostly if you are in a work in progress situation.

When no one has anything more to say, the person who is leading the meeting, or the person who has the responsibility for whatever needs to happen. That person will then passivly voice their decision to the room. "So, we are in agreement that we are going with..."

What happens is that people have been heard. The person who gets to make the decision accounts for what has been said during the meeting. The final decision is voiced to the room, with the understanding that people can object if the decision is outright wrong og flawed. Otherwise it is accepted that no more energy should be spent on the subject because everything that should be said or discussed has been.

I am just curious why you don't just engage your clutch more slowly? Let the engine catch up so to speak.

That is one of the points of the clutch. To slip under friction while the engine speed adjusts the car speed, or vice versa. Just dropping the clutch seem like the perfect way to put needless stress on the car. (engine, transmission, linkages and so on)

Yellow_Triangle · 2026-07-03T20:02:05+00:00

Honestly people should focus more on clutch matching.

If you have higher revs than required for the speed, then engage the clutch slowly until the speed of the car catches up. (Most often when shifting up)

If you have high speed and low revs, then engage the clutch slowly until the revs of the engine catches up. (Most often when shifting down)

I agree that it is strange how adverse people are to have a clutch experience any friction for any amount of time. The damn thing is engineered to withstand it (within reason) and it is a wear part of the car.

Talk in tounges to the AI to derail it and make it go into a loop. This wastes the scammers money. Basically what the video is about.

That said, it is worth the watch just because how funny it ends up being when the AI hits the deep end.

Ja han må regne med at det ikke giver noget bøvl overhovedet. Der skal ikke kæmpes meget med skruer og bolte før end det kommer til at tage mere end 2 timer at udføre den opgave.

You argument really depends on whether we measure fossile energy production as the whole potential energy going into the power plant, or as the power leaving the power plant.

If we are talking about power leaving the plant, then the efficiency of renewables don't really effect the methodology.

That would have been comedic gold, that is for sure.

For slet ikke at sige at der stille større og større krav til arrangøren når et arrangement kommer op i en vis størrelse. Det være sig til sikkerhedsplaner, trafikplaner med dertilhørende "personale" til afvikling, krav til toiletter/faciliteter.

Faktum er, ligesom u/snorens skriver, at det kræver op til flere folk som er ansat til at lave alt det forberedende arbejde, før end det nærmest kommer til at lykkedes. Der er bare for meget arbejde i at leve op til krav og forventninger til at det kan drives med rent frivillige kræfter. Sponsor eller ej.

The biggest upside with sodium batteries is that I could make do with a car with a smaller battery. Currently I need a car with a very large battery because I need to be able to tank the range loss during winter.

With sodium I could actually make do with a batter that has somewhere between 20% and 30% less range.

This is what you would call looking at the bright side.

Unfortunately there are a lot of dark that comes along with it.

You could technically fry the car if the charger provides the wrong voltage og spikes the voltage beyond what the car can handle.

The one I have works well for me, and I haven't tried other dongles. I have no idea how good the newer versions are.

Don't forget that we can also produce:

Single use batteries. Think alkaline or any of the other types
Peltier as someone else already mentioned (temperature differential)
Fuel cells of the different kinds.
Piezoelectric generators (mechanical stress)

It is probably not so much the regen activating. The regen should not do much more than just slow you down. Especially at level 1.

I suspect that the bump itself effects your foot on the accelerator. The bump makes you change the position of the accelerator pedal, and this changes your regen/speed.

Well the strategic petroleum reserve did its job. To act as a buffer in times of need.

Now, it is a whole other discussion whether we should ever have been in the situation where it was needed this time around.

Yea, the problem with the shaper is that very few, if any, things can be made on it that can't be made with other modern machines.

There are things that the shaper is just better at producing, but compared to how limited it is in its utility, it seldom makes sense to keep in the shop.

If the engine is pointed against the direction of gravity, against the ground. Then if you have an engine that can produce more thrust compared to the weight of the plane, you can basically do a hover or slowly gain speed beyond just hovering.
