Rules (2024-08-30)

  1. This is an English-language community. Comments should be in English. Posts can link to non-English news sources when providing a full-text translation in the post description. Automated translations are fine, as long as they don't overly distort the content.
  2. No links to misinformation or commercial advertising. When you post outdated/historic articles, add the year of publication to the post title. Infographics must include a source and a year of creation; if possible, also provide a link to the source.
  3. Be kind to each other, and argue in good faith. Don't post direct insults nor disrespectful and condescending comments. Don't troll nor incite hatred. Don't look for novel argumentation strategies at Wikipedia's List of fallacies.
  4. No bigotry, sexism, racism, antisemitism, islamophobia, dehumanization of minorities, or glorification of National Socialism. We follow German law; don't question the statehood of Israel.
  5. Be the signal, not the noise: Strive to post insightful comments. Add "/s" when you're being sarcastic (and don't use it to break rule no. 3).
  6. If you link to paywalled information, please provide also a link to a freely available archived version. Alternatively, try to find a different source.
  7. Light-hearted content, memes, and posts about your European everyday belong in other communities.
  8. Don't evade bans. If we notice ban evasion, that will result in a permanent ban for all the accounts we can associate with you.
  9. No posts linking to speculative reporting about ongoing events with unclear backgrounds. Please wait at least 12 hours. (E.g., do not post breathless reporting on an ongoing terror attack.)
  10. Always provide context with posts: Don't post uncontextualized images or videos, and don't start discussions without giving some context first.

(This list may get expanded as necessary.)

Posts that link to the following sources will be removed

Unless they're the only sources, please also avoid The Sun, Daily Mail, any "thinktank" type organization, and non-Lemmy social media (incl. Substack). Don't link to Twitter directly, instead use xcancel.com. For Reddit, use old:reddit:com

(Lists may get expanded as necessary.)

Ban lengths, etc.

We will use some leeway to decide whether to remove a comment.

If need be, there are also bans: 3 days for lighter offenses, 7 or 14 days for bigger offenses, and permanent bans for people who don't show any willingness to participate productively. If we think the ban reason is obvious, we may not specifically write to you.

If you want to protest a removal or ban, feel free to write privately to the primary mod account @EuroMod@feddit.org

Wireless charging wastes a ton of power. Roads also get beat to hell.

I really don’t see this being practical.

So an overhead wire would be better right? Then we could attach multiple trailers together, that would be neat !

Let’s replace the road with something more durable! Iron should do the trick. Also if everything is attached, only 1 person really needs to drive! That would free up a lot of people’s time.

[–] BestBouclettes@jlai.lu 12 points 1 day ago

That'd be so neat!

busses are just mobile train cars change my mind

Well, Germany was already testing this. And having it seen live personally on a vacation (we happened to take that road where this was tested by chance) - it just looked like a shitty version of a train...

Somewhere like North America I could see how it makes sense. There's a lot more road infrastructure than rail, and this can be built over it fairly cheaply and easily.

These strike me as a much better plan than in-road wireless.

Though, I wonder what the durability of these are compared to the same you see in cities for trams. Big difference for those is the speed. Would they get worn away too fast? Can they economically make the cables extra thick/hard to compensate?

[–] elvith@feddit.org 6 points 22 hours ago

I mean regular trains do use them all the time and those can go like 80-320 km/h (or even faster in other countries) where as truck only go like 80-100 km/h in Germany.

I'm more concerned how much the amount of trucks wears them down compared to trains. You need many more trucks than trains for the same amount of goods and also trucks have a much higher frequency.

[–] lime@feddit.nu 19 points 1 day ago

could even make the electric truck road separate from the normal road, for safety.

Less batteries, lighter vehicles. Makes a lot of sense. And while roads get beat to hell, I assume it doesn't affect it that much.
