Cheaper Floodwalls
Via NRO,
this interesting article about how the floodwalls appear to have broken. It raises the question of sabotage, since the walls broke
after the hurricane itself passed through. Did barges hit all of these spots? Or were they moved by something less accidental?
Our own environmentalists have been thinking about ways to break dams and levees for a
long time. Google "Monkey Wrench Gang" to see a panorama of sabotage plans. Since the monkey-wrenchers and the Mohammedans want the same century, and since Adam Pearlman-Gadahn has linked the two groups in a more formal way, it's worth pondering.
If the breaks resulted from overtopping, there is a neat new technology called "Invisible Floodwalls", which avoids overtopping without completely rebuilding the entire levee system, and without permanently raising the visual blockage of a floodwall. It's already being
used in Grand Forks, ND. Note: the Corps approved this method, so they will undoubtedly be considering it among many other possibilities. I'm just sort of placing it on the blogworld table here (i.e. Technorati) ... so when a porky politician says it's impossible to improve the walls without total rebuilding, this answer will be a bit more available for public debate.
