Floating Wind Turbines

Here is an idea by way of Norway:

This news story reports on the start of a 2-year test of a floating wind turbine. By combining the technology of land-based wind generating systems and the technology of floating oil drilling rigs, they have come up with a way to put a wind turbine in ocean waters (up to 700 m, which is over 2000 feet, deep) where a conventional off-shore turbine could not be built.

This is a way to build a wind turbine far enough off shore that it cannot be seen from a tourist area (a big problem for plans to build wind turbines off of Cape Cod and a potential issue in Florida as well) or interfere with shipping lanes.
