Folks,
If you do any research on this:
1) It is driven by the green /climate change movement. Not economics.
2) It may be appropriate Technoloy for appropriate situations. Just like electric cars are.
3) It will fail as the it is being promoted as one size fits all, just like everything else. Instead of letting the market place make the decisions.
4) Idiots think you just need a small propulsion system to get in and out of the harbor.
It’s not new. It’s been around for a hundred years. See posted pics of actual ships ...............................
And going beyond what you have pointed out, why didn’t rotor sails catch on a hundred years ago so that every ship afloat today would have “Cylinder sails” as they call it?

Since youndid the research provide a source.
