A nice piece here on new ways to harness wave energy with underwater buoys. These would be less intrusive than surface buoys and present no boating hazards . . . would be fun to explore while diving too!

“A town with 55,000 inhabitants would need half a square kilometre of seabed covered with 100 buoys to power it,” AWS states.

The Pacific coast and the Western edge of Europe would be prime candidates because of their active surf, no luck for the Mediterranean though, too calm . . .
