Rules for Posting Guides on Our Community

1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.

2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.

3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.

4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.

5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.

6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

Ferry super sus. Like a cruise ship, but starts and stops more? Doesn't make sense.

There is many small ferries in the UK which are basically a floating platform that get's dragged through the water on a cable. If you run that off an electric motor those can be quite efficent.

Maybe they are thinking about those.

What is producing the electricity? If it's clean energy, maybe. It shouldn't be "thinking about those," but rather trying to compare similar load to energy cost per person. If the underground, rail, etc can't beat something that has to push through water that doesn't really make sense.

What is producing the electricity?

That question can be applied to all the electric forms of transportation of the chart though.

But if we assume it's the about the same energy mix as for the tube or trams, then it isn't that surprising. Volecity is major factor in the drag equation and ferries move very slow but have high capacity, so even with the additional drag, moving on cables should be closer to rail efficency than to a ship which has to use a propellers.

It's still odd that it's below those other two, but I would have assumed they are in the same ballpark.

So bicycles are not a major form of transport?

You're breathing more intensely than usual, so there is some overhead. But then again walking would take longer and may produce more carbon overall for the same distance

And don't forget the methane from your farts.
