The use of horizontal-axis wind power mills is easier on land than at sea due to their large average size. A new, smaller and easier, 10 megwatt design may help.New Energy Focus.com reports:
"British company VertAx Wind Ltd has appointed marine engineering specialists SeaRoc to devise a safe way to install the machines, as the technology enters its second phase of development. Wind turbines used in offshore wind farms are currently based on horizontal axis designs, but making them bigger to make maximum use of the high winds out to sea is physically difficult. VertAx believes its vertical axis design offers a much easier way to scale up wind generation machines - and will also see them requiring less maintenance, another key issue for wind farms installed in the open ocean."
