  1. Thank you for this video! One thing I like about both rotor and wing sail technologies is they can be retrofitted to older ships. That seems like a definite advantage over alternate fuels like hydrogen and ammonia that can only be implemented with redesigns that pretty much require a new ship. There are a lot of cargo vessels out there already - and unlike cars, the companies that own them intend to use them for as long as possible so they can get their investments back. So technologies that can be retrofitted to older vehicles are much more likely to be adopted. I kind of love the wing sails, and hope they work out. You say their claim to reduce carbon emissions by 90% is kind of hard to believe, but I hope there's something to it. It would be wonderful to have a new age of sail, but this time made more efficient by wing sails and weather tracking technology.

  2. You make very good points there. Imagine an ammonia leak at sea! It might produce a death boat with nobody at the controls, that no one can approach without wearing protective gear.
