The earth swallows a river
6/3/11The earth “swallowed” the river in an agricultural area at a distance of about 800 m. from this town of 9,000 inhabitants in the Santander province town, authorities said in a broadcast over the Colombian radio station RCN.
The 15,000 tons «Maartje Theadora» is the first fishing vessel to use this system, which is an invention of the «SkySails» company, and which consists of a blue and white “kite”, sized 160 square m. which will pull the ship by a rope of 300 meters, aiding the ship engine. The “kites” will generate a pulling power of 8 metric tons, comparable to the power of an Airbus A 318.
