The Swedish 'freighter of the future' concept Oceanbird cargo ship with five colossal 260-foot extendable wing 'sails' that promises to reduce harmful emissions by as much as 90 per cent.
The 650-foot-long aerodynamic Oceanbird vessel can transport 7,000 cars at an average speed of 10 knots, powered mostly by wind.
A transatlantic crossing on the vessel will take around 12 days - only slightly longer than today's fossil-fuel powered cargo ships.
Shipping is a central function in global trade and stands for around 90 per cent of transported goods all over the world.
When completed, it will be the world's largest sailing vessel at 650 feet long and 130 feet wide.
The ship will be ready for customers to order at the end of 2021 and the first vessel will be delivered at the end of 2024, although prices are undisclosed.
