(PhysOrg.com) -- Way back in the 70’s Georges Mougin, then an engineering graduate, had a big idea. He suggested that icebergs floating around in the North Atlantic could be tethered and dragged south to places that ...
Back in World War II there was a clever idea to use icebergs as floating aircraft carriers, but now we know birds of prey got there first.
