Wow. A 25% efficiency boost is huge, both for the shipping company and for the planet.

Wikipedia states that 3-4% of the global carbon footprint is shipping. https://en.wikipedia.org/wiki/Environmental_impact_of_shippi...

CO2 is cut by 27% through a combination of systems. I think the MALS (air bubble) tech on it's own increases fuel efficiency by ~10%, based on the published papers, and you spend 2% of that gain on actually producing the bubbles.

Apparently break-even on the upgrade cost is reached within a couple months. They are also starting to put it in cruise liners [1].
