Heh!  :)    Just ask around. The rest of the world has been building
offshore wind farms for many years.

... planning stage include Dogger Bank in the United Kingdom at 4.8 GW, and Greater Changhua in Taiwan at 2.4 GW

Cool!  Thx Billk.  A wind turbine at sea is almost a win/win.  We get the nearly clean power and don't need to look at the damn things or worry about them swatting birds all over the place.  I was at sea last week, only about 20 miles out from shore.  No birds.  The continental shelf goes out a ways, on the US east coast it does.  Even if it is close enough to shore for seagulls, well... there are plenty of those and gulls might be nimble enough and smart enough to evade them.

Sea air is highly corrosive, so it makes for an interesting mechanical engineering puzzle to figure out how to make those rigs corrosion resistant.  With sea-based turbines, we have a most interesting possibility: water-cooled oil.  Heat dissipation is a big challenge on those installations.  We could perhaps create a dynamic seal, send the hot oil down to the sea surface in a continuous flow, drop the heat into the sea, cool oil keeps everything fresh up top.

The boat people won't like it.  But there aren't very many of them.
