Wind may be an infinite resource at sea, but its exploitation remains a challenge for large-scale maritime transport. During the first campaigns around France and in the Mediterranean sea, the Energy Observer tested two vertical-axis wind turbines for producing energy, and a traction kite to reduce energy consumption.Read moreSaint-Malo, France The Innovations
