“giant kites” mfs really just forgot the word for sails
It’s actually proper kites, at least the pioneering tech is kites. They’re computer-controlled, deploying and retracting on the push of a button and navigating themselves into and out of winds to complement the main drive and controls. It’s been on the market since the early 2000s and has always made economical sense, but:
There’s a structural problem slowing down the process: ship owners (who have to make the investment) often don’t pay for the fuel – that’s the charterer’s duty. The charterer on the other side doesn’t charter the ship for long enough a period to make low-carbon technologies pay back.
From what I’ve seen it’s kites acting as sails so you aren’t bound to using a mast which takes a lot of space and limits your sail area
I think they are actually proper kites flying rather high (at least compared to regular sails) in approximate 300 m AGL.
The big difference is that at this hight there is significantly stronger wind.
Wanted to see what that would look like and found more info here: https://www.euronews.com/green/2021/12/20/this-huge-kite-is-dragging-cargo-ships-across-the-atlantic-ocean
Billionaires reinventing the train is out, billionaires reinventing the sailboat is in
If billionaires reinvented sailboats it would be some shitty CGI pod powered by nfts.
