Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Here is a 10m-resolution map of the Mediterranean coast of France. Doesn't seem good: a rather steady fall to about 100m depth right from the shore, no plateaus higher than -100m. So off-shore wind would be possible only in the nearest band beyond the shore.

This map is a perfect example of why offshore wind is such a good fit for the North and Baltic Seas.  The largest pool table in the world.

While the US has three very long coasts, much of it is similar to this section of France, and is the reason why current offshore wind may be limited there.  The difference is the US has a Saudi Arabia worth of undeveloped onshore, even if that entails significant transmission cabling and costs.

Another possibility looms in the near future.  Floating designs are already being tested, and more are on the drawing boards.

Could these floating designs also incorporate wavebob technology to create combined wind and wave power generators?

I'm not familiar with this technology, even after checking the website, but it's doubtful it would be used on a stationary or floating foundation, as the wind turbines need to remain relatively stable.  A site electrical grid could possible be used together, if the power is compatible.

What an involved way of saying i don't really know.  But the reasons for doubt must be addressed.

The submarine canyons visible on that map are magnificently displayed - a perfect example to show that rivers don't always stop at the shore.

Isn't that particularly the case in the Meditterannea where the shore was much, much farther a few millions years ago ? Those canyons were dug by rivers before the shore, if I remember correctly.

It's indeed thought that many of the dramatic Meditteranean submarine canyons were largely shaped through intensified river erosion, because of the Messinian salinity crisis, some 5-6 million years ago - whereas the erosional forces of rivers are thought not to have been as dramatic for the rest of the world.
