This is Oceanbird. A cargo ship, designed by the Swedish company Wallenius Marine to reduce CO2 emissions related to maritime transport, and sails thanks to wind energy. Thanks to the five large telescopic wings of the height of 80 meters that will be equipped with algorithms for the exploitation of the wind, the ship 200 meters long and 40 meters wide will be able to navigate at a speed of ten knots (that is, 18 km / h). According to Wallenius Marine, with 7.000 cargo cars, the ship will take 12 days to cross the Atlantic. The ship is expected to be built in 2024.
