What is the currently maximum available performance of NACS?

CCS is designed up to 1000V and 500A. Charging stations offer typically up to 350 kW.

What do the available NACS charging stations offer? As I remember Tesla is only using 400V batteries, so with 500A they only get up to 200kW.

So the switch to NACS sounds like a performance downgrade. But yes: probably a usability upgrade but at the cost of longer charging times.

Is Tesla planning to switch to 800V too? So they can deliver more performance?

Actually, it’s not just another plug. The fact that the same Pins are used for AC and DC charging adds a little bit more complexity to the car. Either you need additional switches in the car to separate the Onboard AC-Charger from the charging port, or the AC-Charger must be designed to withstand an DC input on its AC-Input contacts. That probably won’t be the biggest problem when the DC-voltage is just around 400V, as the AC-voltage is not that far away.

But if you switch to 800V Batteries (which most of the industry is doing), that probably could get more challenging, as the AC-charging-voltage won’t change.

We‘ll see what the car industries solution will be.

A lot of incredible science would be involved. And much much more money and a lot of time.

If we (humanity) could achieve that, that would be really cool.

But: how much solar-, wind- and battery-farms could we built with the same money and in much less time?

Fusion is great, but it will probably not be the solution of the energy demand we currently have. Nevertheless it’s something we should pursue furthermore. But we shouldn’t bet everything on it.

Probably because the need of moderation.

If you host an instance and let people in (even if it’s a limited circle, i.E. your students) you are responsible for moderation. I think that’s something institutions back off currently.

For an mail server that’s much easier.

What about mobile apps? I’m on mastodon, but I basically never see the mastodon UI as I stick with Ivory (as I’m a former Tweetbot User on some ancient Microblogging Plattform which has transformed to something… else).

I don’t want to use some „nice looking“ Webpages which are optimized for mobile screens. I want dedicated Apps, as they offer mostly the much better experience.

I think the recent run of developing high class Mastodon Apps earlier this year (as the mentioned ancient Plattform kicked them out) gave mastodon an enormous boost.

Also that’s the same for Lemmy for me. Since Memmy and Mlem are in the AppStore (where I preferred Memmy), I use Lemmy much more and haven’t opened Reddit since 1st July.

So, as long as there aren’t any major high class mobile Apps for firefish, I don’t expect it getting anywhere near to mastodon.

Let’s see. I work at a huge corporation (tens of thousands employees each with his own laptop). Until now: only windows, currently since a few years HP Elitebooks (the suck completely if you need a little bit power) and optionally some zBooks.

Some months ago they introduced MacBooks as another option. But with less support and some things a bit more complicated as the corporation completely relies on the AD user management.

Unfortunately we have a ton of custom made software applications or specialized software which - of course - run only on windows. So currently, the MacBooks are only an option for the typical Outlook, PowerPoint, Excel user.

I don’t see this being transferred to complete Mac compatibility within the next 10 years. Probably step by step (we just started using Codebeamer as our Requirements Engineering tool, which is completely web based. That’s nice. :)

But that’s just the first step. We‘ll see in a few years.

By the way I’m not sure if Microsoft would be that sad if people would use Macs more than windows. As long as Microsoft can continue to sell Microsoft365 and alle their other Azure services. That’s where they make the money. They don’t really make money with windows.

And with Satya Nadella Microsoft changed its focus: Bring the product to every single platform, not only windows. iCloud is nice, but I don’t see the huge functionality the Office Cloud brings into the game with all the tools Microsoft has to offer. Apple is here far far far away.

So if in the end, the companies use Macs to access Microsoft365… well. 🤷‍♂️ it hopefully runs better than on windows.

If hate my HP Elitebook 850 G6. Even with 32 GB RAM. It sucks.

The reliance on fossil fuel didn’t change a lot since shutdown of the last nuclear power plants. And basically… nuclear is also fossil. The fuel rods aren’t just there. They consist of materials which are mined. The difference is only that they are not emitting CO2. But instead the nuclear waste has to be stored for some thousand years. Germany already has a lot of tons of waste and still no place for final storage.

And as we could see last year in France, nuclear isn’t also that much reliable too.

The quitting of nuclear energy was still the right decision. The timing together with the Russian/Ukrainian war wasn’t the best, but unfortunate something like shutting down a nuclear plant ist something you can easily postpone when the plan is planned and startet to execute. Also a bad decision of previous german governments was to shut down nuclear plants and not building up a replacing renewable infrastructure. So in the end, there was no other choice for the current government to shut them down and rely on gas and coal a bit more than they wanted too.

„… which is rapidly becoming the de facto charging standard in North America and Europe.“

Wait? Europe? I have never heard of anyone in Europe switching to NACS. Europe is all CCS2, even Tesla uses CCS2. Only Model S and X are using a custom Tesla-Solution which is based on the Typ2 AC-Connector. An probably switch to CCS2 in the next generation cars.

So, definitely no NACS in Europe as far as I know.

I run a private Mastodon Instance. The server gives me the option to automatically delete the media-cache after a given number of days (I have it set to 180 days). If the data is needed again, it will be pulled from the original instance. Again. If still available.

An additional setting is the deletion of the federated content at all, which is saved on my server. This probably cannot be reverted, as the server doesn’t know anymore what to pull from what server… I have this setting at 365 days.

Additionally I can set my personal account to auto delete my own posts after a given time. With being able to set some excludes (favorited, bookmarked, posts which got a minimum of likes, …). But this is not a server setting, it’s an account setting.

Social media does not need to be saved forever. :)

Well… for iPhones (and other smartphones) I’m not sure if anything changes. There is a exception in the regulation: if the device is waterproof, it is enough if the manufacturer or repair shops can change the battery for you. They do not need to be user replaceable.

But probably for MacBooks, there will be replaceable batteries in the future. I don’t see, how Apple will find a way around this regulation.

Apple Watch: they are waterproof —> nothing changes.

AirPods: well… are they waterproof? I don’t see user changeable batteries ever. Perhaps they will become waterproof in the future too? :) AirPods, now also for swimming and diving!

iPads: well: probably there will be changeable batteries in the future. Or we will have underwater Tablets soon. We just need another input method. Probably gestures like the VisionPro?

Hui. r/interestingasfuck hat auf NSFW umgestellt (damit Reddit keine Werbeeinnahmen dort bekommt) und scheinbar sämtliche Moderation eingestellt. r/porn ist dagegen vermutlich harmlos, was da gerade abgeht. Wild.

r/wellthatsucks hat einen anderen kreativen Protest. Dort geht es jetzt um Staubsauger.

Diese Mod Teams zeigen jetzt ein bisschen Kreativität. Ist fast schon wieder lustig. :)

Well… the question should be: where does all this electric charge come from? I you harvest it from humidity in the Air, the charge would removed. Thus, you have to replace the humidity in the air with fresh, „charged“ humidity.

Is there any natural effect, that this works automatically? Or do you need a fan? How much energy would that need?

Too much questions, too less details for a too simple solution.

In an ideal world, automation could free up the human workpower to relevant topics (instead of taxi/Uber/etc.). Science, development or even social working.

But as we are not in an ideal world, this would never work, as it would need equal and ver could education where you see every student what it is: essential brain capital which must not be left ignored.

So the reason why we get automated driving is: because we hate monotonously driving every day the same route through the traffic jam.
