US Navy launches kites (to save fuel)

For the first time in the history of the fleet on one of the US Navy transport ships, a computer-controlled giant kite was lifted into the air. According to experts, this will help save from 20% to 30% of fuel, that is, about $ 1600 per day.

The ship has been modified by the Military Sealift Command (MSC), which transports military equipment across the Atlantic. The ship’s engines are now assisted by the 120-meter kite MV Beluga, produced by the German company SkySails .

This is really a huge snake in the form of a paraglider, it hovers at an altitude of 100-300 meters in the sky and pulls the ship behind him.
