This is super cool. I hope it pans out this time. I've seen a number of attempts to add sails to cargo ships in the past, and generally they have not been a success because it involves adding a skilled person to the crew to manage the sails and cargo companies are allergic to paying extra salaries, even if they manage to make more than their salary back in fuel costs.
