btw cargo ships are already incredibly efficient tho.
even if they produce a ton of co2, when divided by actual amount of goods delivered, they are hundreds of times more efficient than trucks

Yeah, we really should swap out all those trucks crossing the Atlantic with cargo ships.
Why don't we just replace all the trucks on the road with cargo ships?
Oh absolutely. But why not make them even more efficient?
1,000x efficiency is good
100,000x efficiency is better.
Besides, now is the best time to do all the r&d for when fossil fuels are non-existant. Better to figure out how to mixmax wind while you have other options than when you have no choice.
My company makes sustainable packaging, and the primary way we compete as a sustainable bag product for our food grade division is eliminating the CO2 costs associated with shipping overseas (most reusable grocery bags are made in China).
As a result, it takes around 600 of our paper bags to be as bad for the environment as one reusable bag.
While overseas shipping is necessary and as efficient as it can be (so far!), it is still a major greenhouse factor (so far!)
Also everything that touches a container ship ends up on a truck at some point, so there's not really any savings there.
Fingers crossed for the Golden Age of Sail Part 2: Wind Boogaloo, even if it hurts our bag division a bit. The net gain is too good to ignore

#BringBackTrains
Kind of hard to send cargo by train across an ocean though...
Ramps. Jump it over the ocean.
Twas in reference to trucks. Highways have replaced rail and so trucks have replaced trains.
When russia collapses and the US turns Siberia into west Alaska we can just build a bridge across the Bering strait.
Yeah but in the future Arasaka is going to lay a ton of AI controlled mines all over the ocean and lose control of them and ocean travel will be impossible. Oh wait, that’s just a ttrpg and a video game. A corporation would never do something like that in today’s world…

I was ready to mock this, but the more I look into it the more sense it makes.
Honestly I had the same thought process

From the Wikipedia article linked below:
A rotor ship is a type of ship designed to use the Magnus effect for propulsion. The ship is propelled, at least in part, by large powered vertical rotors, sometimes known as rotor sails. German engineer Anton Flettner was the first to build a ship that attempted to tap this force for propulsion, and ships using his type of rotor are sometimes known as Flettner ships.
https://en.m.wikipedia.org/wiki/Rotor_ship
See also the Magnus effect.
So nice of Magnus to put aside his chess career to help the planet
Not to mention his career as a chaos demon
What an extremely cool thing to learn! And the gifs on the article are very helpful

I know it's just me, but everytime I hear the expression 'What a time to be alive!', I think of the voice of the host of the Two Minute Papers YouTube channel.
Edit: I thought it was just me, but it wasn't just me
I think of this scene:
A fellow paper enjoyer!
Hold onto those papers!
Isn't it like 20% fuel reduction only? Not insignificant
There are lots of grand claims for the potential of wind assist on ships, but I suspect they're based on idealized physics and best cases. Actual results seem to be less impressive https://www.ics-shipping.org/news-item/potential-of-wind-assisted-propulsion-hindered-by-perception-and-funding-challenges/
They claim 5-10% fuel savings, which is decent, but not earth shattering. Pyxis, which started operation in August with two big wing-sails, is likely to be the best current practical evidence, but I haven't been able to find any results online. Speculation that it might reduce fuel consumption by 3 tons/day, which is about what you could get just by slow steaming.

Do cargo ships go under bridges?
Many do not. Few bridges cross major harbor entrances.
But I've also seen this concept before. The sails retract. If you look closely you can see how they're segmented.

Certainly not this one
Boats with sails?? Blasphemy!! How are they going to stop when they get to the edge??? Argh,me and me mateys need fossil fuels..mo mercury mo problems, ya heard?
You sunk my cargoship.
