    This is fascinating. I got questions.

    What’s the ROI? Is it a no-brainer to install these things for the cost savings? If not, and if they prove out, governments should look at making them mandatory and providing partial subsidies. Or, maybe an easy loan to jump start adoption?

    This video answered some more questions. They do indeed fold down for rough weather and clearance and appear to rotate 360°.

    I’m assuming they’re computer controlled for max efficiency?

    Not seeing any downsides here.

        According to that video, they fold out of the way. I’m not sure if they currently fold on the real ones. The article mentions:

        the 125-feet of height added by WindWings could potentially complicate docking in many locations. According to Jan Dieleman, president of Cargill’s Ocean Transportation business, they’re already working to address such issues.

        Which seems to imply they don’t. Their solution of modifying ports to accommodate the sails might mean the folding aspect wasn’t viable?
