Concept Cargo-Ship Powered by Wings

A concept cargo-ship powered by wings, titled the “Oceanbird,” has been designed by an innovative team of Swedish researchers and boat builders.

Wind and Wings 
——————–
The ship is powered by a pair of massive wings instead of a traditional engine. By using the wind instead of fossil fuels, the ship could cut down on emissions ( Learn moreconcept.
The huge wing-like sails are designed to be able to swivel to catch the wind. They can also retract to go under bridges. 
The ship uses five wings, each being 262 feet long. They are made from metal and composite. They are twice the height of the sails on the biggest sailing ships today. 
The ship is designed to be 656 feet long and 131 feet wide. This will make it the world’s largest sailing vessel when completed.

Sustainable Cargo Ships?
————————
At present cargo ships carry around 90% of global trade, roughly 11 billion tons of goods each year – and are major contributors to greenhouse gas emissions ( Learn more ). 
“Oceanbird” was designed to be a car carrier capable of carrying 7,000 vehicles, but Marine said the technology could easily be adapted to other types of vessels, including cruise ships.
The tradeoff associated with wind power is that “Oceanbird” can carry 7,000 cars across the Atlantic in 12 days, rather than the 8 needed by traditional cargo ships.
