Floating contra-rotating wind turbine delivers twice the energy of today's largest turbines. Norway-based company World Wide Wind (WWW) has unveiled a new kind of floating, vertical-axis wind turbine (VAWT) that has the potential to revolutionize the way we capture and utilize wind power. This novel VAWT design uses two sets of tilting, contra-rotating blades to deliver twice the output of today’s largest turbines.
