windmills sited on dykes would be very high performing turbines, due to stronger winds and less turbulence. That means stronger foundations adapted to dyke needs would be feasible. For example, there could well be hybrid foundations using some of the offshore technologies, using piles or jackets.

There are methods to build to dyke requirements. Whether the tourist industry would agree is another story. As the costly reality of poisons for generation creeps into society, and after the next nuke disaster, high capacity factor wind turbines on dykes won't seem so out of place.

Further, there are already offshore scale turbines (with 120m + rotor diameter) on land in Belgium, The Netherlands, Denmark and Germany.
