In the bay of fundy they discuss tidal turbines for power generation. I
think the goal was to make a string of these at the lowest sea levels; when
I first heard about it, I thought they would want to float those turbines.
I don’t know where your discussion about 10,000 tiny turbines on the facade
of high rises came from, but maybe if it was a long, linear squirrel cage
sort of spinning thing it could be a shape that could work. It may just be
changing the form that the tech is taking. I thought someone deterimined
that the human being was about at the midpoint between the largest things
and the smallest things in the universe. Was that Feynman? or Nova?
