We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.

https://en.wikipedia.org/wiki/Energy_efficiency_in_transport

that table is thoroughly fascinating. i mean all of them, there's more than one table on that article

apparently walking is the most energy-efficient transport mode of all?!?!? apart from bicycles

what i find mind-blowing is that airplanes consume approximately the same amount of energy as cars and trains. I mean i can easily see cars and trains being on the same level, but i always thought that airplanes consumed like an order of magnitude more fuel than cars. considering how everybody keeps saying that "airplanes consume so much fuel" and such. crazy.

and also boats are less efficient than i thought? boats consume 16 L/100 km while cars, trains and airplanes consume 6 L/100 km?

My guess is taxis and things like Uber.

Something you have to call up/book to get anywhere

It's a bonkers newish form of not-a-bus, often running passenger vans, usually operates where you either book your rides a day or two in advance or book with an app and wait 5-120 minutes for it to show up, and the service runs door to door.

They're ultimately super inefficient in the real world requiring an extremely high driver:passenger ratio to be at all competitive with bus services

Edit to add: it's basically the answer to "what if taxi replace bus?"

[–] Swedneck@discuss.tchncs.de 1 points 2 weeks ago (1 children)

oh come off it, it's a great way to provide service in areas that are NEVER going to get proper bus lines otherwise.
We use it in most of sweden (as a fallback in rural areas) and it's perfectly functional.

[–] Trainguyrom@reddthat.com 1 points 2 weeks ago (1 children)

Oh yeah it makes perfect sense for very small towns and rural areas, but when a city with a population measured in the hundreds of thousands seriously tries to run a demand response transit system as literally it's entire transit system, it deserves more than this level of derision

[–] Swedneck@discuss.tchncs.de 1 points 2 weeks ago (1 children)

right, but maybe americans can try to remember that actual rural areas (as in, something between the density of suburbia and wyoming) do exist, and that the entire world doesn't consist of 30 megacities in a desert? It's very frustrating to see perfectly valid modes of transport dismissed as bonkers and inefficient, when it demonstrably works okay in the right circumstances and enables 90% of my country to have any sort of public transport at all.

I see this kind of thing so often from americans, taking their personal experiences with public transport and their local conditions, and projecting that upon the entire concept of public transport as a whole.
Everything from "public transport is full of stinky druggies and is only for the truly desperate", to "the only form of public transport that exists is buses; trains and trams are ancient and irrelevant". And it's baffling because just looking at how things work in the rest of the world would immediately disabuse those notions.

Hey man, I get the frustration, but your frustration is misplaced. I presently live in a town of ~10k people, married a woman who grew up on a goat farm outside of a town of 700, I work in an unincorporated community of around 400. I just took a big vacation in which I rode about a dozen different transit systems, and I'm already planning the next one. I'm a freaking model railroader and I've been looking at potential adding a running model bus system to my model railroad as well.

Trust me I get what you're saying, I understand the exact frustrations you've expressed, I just ask you do the same for me
