Can you source your statement that fast charging reduces lifetime?
- Comment on The "standard" car charger is usually overkill—but your electrician might not know that [32:26] 1 week ago:
I‘m not sure if fast charging degrades batteries. Just read somewhere an article stating that fast charging initially - first charge - boosts the overall capacity of the batterie due to chemical reactions that do not occur that long at anodes.
The issue with fast charging was the thermal management - it’s getting to hot. This is managed by good battery management and a different packaging of cells nowadays. I think fast charging isn’t an issue anymore. Can’t provide you a link or such, it’s what I gathered through serveral podcasts.

In recent test of a German suto club they found out that it‘s cheaper/ more effective to charger faster. You loose a lot of energy if you load slow over hours.
This energy is taken by the electricity of the car. So, while charging the car is on and takes some Watts/h. There are just a few brands that habe decoupled the charger circuit from the overall electric circuit of the car.
Can’t find the article now, but I think charging a PHEV through a standard power plug had about 20% energy lost. It was clearly visible that a charger is a good choice.

Good point.
However, there‘s a crucial difference to cars. Robots are hardware AND software. And I don’t know anybody who uses Windows 95, CorelDraw, and Netscape today. Software and connected hardware outdate mich faster than simple hardware.
- Comment on Hyundai begins using Boston Dynamics humanoid robots at US factory 1 month ago:
The battery! It lasts for just 1-3 hours. That’s why there aren‘t robots on the battlefield nowadays. Once the energy issue is solved this will change
- Comment on Hyundai begins using Boston Dynamics humanoid robots at US factory 1 month ago:
Sure. But at what costs? One can do many things by technology. Are people willing to pay for it? And how much?

What do I do? I‘m a cooker. Yeah I cook meals. Early in the morning I press this button and meals get ready and dishes cleaned and served. That’s cooking today.
I love it old school. Cooking on a stove, cleaning dishes by hand and peeling vegetables manually. Automation is evil, you know, it takes jobs. That’s why I cook on a stove

Well done. It’s needed so urgent. Craftman still work like in the 60-90ies. They are sooo old school. And call it „tradition“.
If they use a laser for measuring things, that‘s advanced. If they use a smartphone and digital apps for notes and customer contact (instead of pen and manual notebook) that’s advanced. Wtf.
I had quite many craftman in my house last years and it’s unbelievable how they work nowadays. Two of them even didn‘t send me a final invoice. Well, that’s stupid backoffice work. Many couldn‘t send me an offering after having a (time consuming) site visit at my house. One showed up twice because he lost his paper with the measurements. And didn‘t send an offering.
Nono, I lost all my respect about any modern capabilities of craftman. It’s insanely old schooled.
Coming back to the 3d printer: How is construction building up a house nowadays? One after the other is doing their work. Nobody thinks ahead. How do they lay out pipes, lighting or power lines? By cutting into the wall. Why? Because of tradition. Any documentation? With pen and notebook? No way. How laying tiles in a bathroom? Showing up with a stack of tiles and cut it one by one. Laser measure it first and cut ahead at their shop to save time? Well, the leaning walls and tradition, they will answer.
I do not wonder that building up houses became insanely costly.
Sorry for my rant. But my experience were just eyeblowing and frustrating. (And as my mother was a craftman I know that matter a bit)

And if you ignore construction sites with high cranes and not documented buildings. Or overland high voltag power cables, wind mills, hobby drones, and local variations of birds.
It‘s just taking the complex challenges of autonomous drivinf into the third dimension. Making it even more complex.
- Comment on British soldiers tune radio waves to fry drone swarms for pennies 2 months ago:
It uses high frequency radio waves to disrupt or damage critical electronic components inside drones, causing them to crash or malfunction.
At a range of 1km…
That‘s useful not just for drones. I wonder if this works against helicopters, too.

You swap seeing with recognizing. You recognize things. And you see light.
- Comment on British soldiers tune radio waves to fry drone swarms for pennies 2 months ago:
That’s it. And, indeed, you see light. That’s what your eyes do.
Little smart ass knowhow: With your hands, you can feel light. (You feel infrared light as heat. Not visible light though. Just heat up your cooker stove and it emits a bit visible red and a lot infrared light. Don’t touch just keep your hand close to the stove. Now you feel the IR-„light“)

In general an electric car is cheaper than a combustion car. Being it the petrol vs electricity or purchase price. Today, western car companies produce high end electric cars only. That’s why the costs are high. Wait for the Chinese low end cars.

That was until 2023. In 2024 the regulations were changed and kow it can’t be stopped. Neither stopped by your landlord, by the city, nor the local power company. Just buy it for around 400€ and install it (no Deye inverter though). You’ll get 2 or 4 solar panels, an inverter and a cable with schuko plug to connect inverter to your flats power network.
You plug it into your power plug and as soon as the sun glares, your little power net in your flat gets cheap power. If you adapt your behavior accordingly - start laundry, dryer, ironing at noon - you can save some bucks.
I have no quick start guide in englisch. May be you google around a bit. If you live in an older building, you should read about old power cables as well and start with low wattage- 600w inverter. It’s really that easy now 😋

- Comment on Germany hits 62.7% renewables in 2024 energy mix, with solar contributing 14% 5 months ago:
In other news, Germany imports quite some percentage of its electricity from other countries, like nuclear-produced electricity from France. So, in a sense and to a degree, it outsources the emissions to other countries.
That is simply not true. You might get an update of the actual state of energy production AND imports va exports here: pv-magazine.com/…/germany-hits-62-7-renewables-in…
My memory fails me, so it may have been different gas and different purpose than electricity. Anyway, it came as a very poor taste.
Even this is not true or just blabla at least. It’s Biogas, gas made out of animals poo, plants and other degradable things.
I strongly suggest that you either check sources before posting a comment. Or just stay quite instead „there was something I heard somewhere…“

In Germany, from 1st of January each local power provider has to offer a flexible contract that gives through the market price. But I think it’s too early right know as it has some peaks. Otherwise choose Tibber, Voltego or others. Once you can load your car at night, it’s worth to take a flex tariff

Buy a Balkonkraftwerk. It’s cheap right now in Wintertime. If you take one without battery, it has a return of invest of 1-2 years. Just 2-4 solar panels for your balcony or somewhere else and you plug it into your power plug (schuko stecker). It‘s worth, easy to install and allowed without applying the landlord in Germany.
