The next generation cargo ship by Wind Challenger Project, substantially reduce fuel consumption. The idea is to utilize giant retractable sails, 50m high by 20m wide, to make maximal use of wind energy.
The results indicate that hybrid ships could reduce annual fuel consumption by about 30% on average.
“Using today’s technology, it’s possible to make big sails, and to control them automatically. Also, navigation technology includes networked maritime information and weather forecasting, so ships like this can travel safely. Using wind energy, as in old-fashioned sailing ships, is actually feasible.”
