> The idea is not to turn modern cargo ships back into sailing vessels. Instead, these systems are designed to work alongside conventional engines, using the wind to reduce fuel consumption whenever conditions allow.
Given the increasing number of companies that are mentioned as upcoming partners for actual installations, it might be that they've finally been able to convince shippers that wind power is viable for cost savings.
We have had hybrid sail/combustion engine cargo ships for 200+ years, today they are reduced to novelty or historical status. We have been experimenting with goofy hi tech rotary sails for more than a century, and no one has really done more than make a few demonstrators for publicity.
