It needs to be cost effective (which might include profotabilit6), be feasible to implement, sustainable, and a bunch of other stuff too.
Aircraft carriers and subs being the only transportationethod using nuclear is a good sign that it isn't practical for shipping. That is likely a combination of nuclear requiring highly trained staff that are not just out in the work force, the ability to procure a reactor and maintenance parts, the ability to obtain fissible material, the ability to dry dock a ship with a nuclear reactor, and a bunch of other stuff that could even be affordable without being practical for reasons beyond costs.
Best depends on many factors beyond things like efficiency, weight, or durability. Lateen sails are easy to implement with a single mast, are easy to store and maintain, and everyone that has sailed has experience with them. Other sails might do a better job of catching the wind, but with tradeoffs on maintenance and usability.
Practicality is often complex and leans towards easier maintenance and established knowledge.
General rule for ships, at least heavily loaded ships, is to retire after some 60 or so years. There’s no exact number but it exists for each type of ship. Reason is material stress. Even though ship might look okay, they have a lot of stress when transporting cargo or in general dealing with waves. In time, these stresses cause material stress and eventually fracture.
This is the reason behind those videos on YouTube where ship splits in half in high waves. It’s not that ship can’t handle high waves, it’s simply that ship owner wanted to squeeze more money out of the vessel and didn’t want to retire it, even though he was most likely advised to do so.
This is pretty incredible! I hope more industries adopt this mindset and begin to find ways to combat climate change. It’s going to take all industries exerting this level of change!
Amazing, I was reading about the idea of them doing this a while ago. Makes me wonder if the future of shipping will see a return to some of the old trade routes that are more favourable for the winds.
This is fascinating, the sails look quite different from what I would have imagined given the name. Looks more like those ships with the rotating cylinders on them visually, even though of course those operated on a very different principle.
Excited to see how well this works. Would be amazing if they could slash fuel usage significantly, I remember reading even those oversized kites already did a fair bit.
The Pyxis Ocean’s maiden journey, from China to Brazil, will provide the first real-world test of the WindWings - and an opportunity to assess whether a return to the traditional way of propelling ships could be the way forward for moving cargo at sea.
Enabling a vessel to be blown along by the wind, rather than rely solely on its engine, could hopefully eventually reduce a cargo ship’s lifetime emissions by 30%.
It was developed by UK firm BAR Technologies, which was spun out of Sir Ben Ainslie’s 2017 America’s Cup team, a competition sometimes called the ‘Formula One of the seas’.
“This is one of the most slow-moving projects we’ve done, but without doubt with the biggest impact for the planet,” its head John Cooper - who used to work for Formula One team McLaren - told the BBC.
“Wind power can make a big difference,” says Dr Simon Bullock, shipping researcher at the Tyndall Centre, at the University of Manchester.
He said new cleaner fuels will take time to emerge “so we have to throw everything at operational measures on existing ships - like retrofitting vessels with sails, kites and rotors”.

In comments later released by the Spanish football federation Hermoso - Spain’s all-time leading scorer - said the moment was a “natural gesture of affection”. “It was a totally spontaneous mutual gesture because of the immense joy that winning a World Cup brings,” the 31-year-old forward added.
I don’t think either of you know how powerful a moment of elation like that can be. I think she gets it because she was there, living it too. Context, as always, is everything.
Yeah, might. It's good good to question it even if that's the case. Maybe next time someone will think twice about doing something similar if it's not consensual.
I get the sentiment but fuck… every time I see this type of comment it makes it seem as though women are meek powerless individuals it’s like backhanded feminism
I get it’s still a problem I agree, my point is it shouldn’t always just be assumed this is the case that a person has no ability to fend off anyone with a larger power dynamic
Well that’s kind of what the original person said and I gave another option. You don’t know. I don’t know. But saying they’re banging because she changed what she said isnt fair either.
Without relation to what Hermoso (or the RFEF PR team) says, it was not appropriate. Even if they are friends, Rubiales is there as La Liga president, not as a friend.
What would have been the public reaction if Infantino would have kissed Hermoso?
What would have been the public reaction if Rubiales would have kissed Queen Letizia?
This guy is a shame to Spanish soccer, I am surprised the backslash is mainly in social media and the mainstream media is just banking with clickbait low level articles. A shame.
Just for context, it has been revealed that the alleged statement of “natural gesture of affection, etc” is false and forged.
It was released by the Federation, but she never said that.
She has only said that she did not liked it and won’t make any more statements at the moment.
Hermoso was pressured too in the trip back home to appear on the “apology” video from the president (spoiler: he does not really apologize and before that he insulted everybody that did not like the kiss on the radio) but she refused.
The coach tried to persuade the family in the plane too, three times. They did not cave.
