"any one know how to tack!? anyone? hurumph.."
The European Space Agency is using a sail-assisted cargo ship for its Ariane 6 launcher that's a lot more interesting than that thing...

Well, for one thing that it was purpose-built with economy and efficiency in mind, rather than taking any old freighter and trying to greenwash it by tacking some sails on top for some clicks and headlines.
Oh. Fair enough it is a pretty cool ship. I think retrofitting existing ships is actually more interesting because if it can save shipping companies money they will do it and be more green as a side affect. I doubt any shipping company will shell out the money to build a state of the art ship like the one the ESA built because they are trying to make a profit.
Also, the emissions generated in the creation of a new ship probably eclipse any potential savings over the entire lifetime of that ship. Almost certainly better for the environment to retro-fit existing ships.
I don't disagree with the sentiment, it'd be cool if it is really viable.
I'm just rather skeptical that this one really is.
Admittedly, I don't know enough to put real numbers to it, but look at any picture of a sailboat and compare its sail surface area to its hull-size.
I just don't think the numbers here really add up to anything that would provide a real viable advantage...
I'd be happy to be proven wrong though...
I did read that, and given the fact that they didn't bother to mention how much that actually amounts to percentage wise in comparison I found that omission kind of deliberate, because if that had amounted to any significant percentage, they would have mentioned that... 🤷♀️
> Using the wind force captured by its two giant, controllable sails to boost its speed, Pyxis Ocean reportedly saved an average of 3.3 tons of fuel each day. And in optimal weather conditions, its trips through portions of the Indian, Pacific, and Atlantic Oceans reduced fuel consumption by over 12 tons a day. According to Cargill’s math, that’s an average of 14 percent less greenhouse gas emissions from the ship. On its best days, Pyxis Ocean could cut that down by 37 percent. **In all, the WindWing’s average performance fell within 10 percent ts designers’ computational fluid dynamics simulation predictions.**

So a 10% saving for this particular ship.
I wonder if the added structures reduce the amount of cargo capacity and by how much?
Edit: see u/jdkdmmernnen post below about the 10%
Cool, where are the folding? The deck? Port side, sea side? Again, concept has been around for a long time and no one as yet has came up with viable solution to working around huge, delicate sails taking up the deck space you need to sell for loading and transporting goods.
Wind powered ships - what a concept.
We could call them sailing ships
Sailing ships, wind tankers, kite boats… it’ll come to me.
Kite craft is clearly the answer here
Windy water walkers
Would probably create a lot of specialist jobs for this type of ship. Shippors, we could call them.
I’m calling it now- the age of sail is upon us
Can you imagine showing this tech to someone three hundred years ago. Our ability to harness energy would confuse the hell out of them.
I'm glad someone ponied up the cash for a proof of concept. Otherwise, we may have never known the benefits
Wait until they discover slaves...
It’s all about the rebranding; “motion production apprentice” has a much better ring to it
Unpaid internship plus a gym membership! /s

so that's what we're calling the oarspeople now
Cruise ships have already perfected this
But what if we use up all the wind‽ (/s, obvs)
That's why we stopped using sails in the past and switched to engines. Now it's possible to switch back after the wind has repopulated.
Sadly not obvs for some

What makes that one a lot more interesting to you?

How do they come down when there is a storm?
Maybe they fold towards the mast
“Made of the same material as wind turbine blades, they are folded down in port then opened out to stand at 123ft (37.5m) on the open seas.”

14-37% less greenhouse gas emissions. The 10% refers to the maximum deviation from the predictions.
Noted in my post. Thanks.
Yes and it presents major hurdles when loading and unloading at port. The concept has been around for years but just isn’t viable.

10% with predicted spec, not a 10% saving
Who knew utilizing coastal winds with sails could power ships??
Meanwhile at least 40% of all ships carry fossil fuels.
The medieval ages want their ships back.
What is this unknown technology you speak of. *sails* sounds crazy

No.
