Has anyone suggested salvaging all those thousands of empty tractor-trailer-shipping containers washed ashore and using them as bulwarks for the breaches in the levees? I mean you can carry them empty by copter or tracor to a barge and tow them to the levee where, filled with sand/debris they can be sunk. You could weld or bolt chains to them to form a flexible sea-wall even.
I've heard very little on ideas about how to fix the levee breaches. The sandbag idea fell through, though I heard they were having another go at it? Not sure.
