TOKYO - THE world's first cargo ship partly propelled by solar power took to the seas on Friday in Japan, aiming to cut fuel costs and carbon emissions when automakers ship off their exports..link
if only there were some other form of propulsion that could be used to move ships across the ocean ..

you'd think it'd be possible to devise a hybrid wind / turbine propulsion system such that when conditions are favourable, sails could deploy to assist. surely that'd have a much greater impact on reducing fuel consumption than 0.2%..
i'm also guessing that the mass of the sail system would be such that it's not adding a significant amount to fuel consumption when they're not in use.
maybe it's been done already.
