Is This Gigantic Biblically-named Floating Buoy the Key to Saving New Orleans?

Everyone who's been to reconstruct and preserve New Orleans has been going about it all wrong, apparently. While they were foolishly toiling to rebuild buildings damaged by Hurricane Katrina, they should have just been building a humongous, floating pool toy.

From Gizmodo:

NOAH (New Orleans Arcology Habitat) is a massive, 1200-foot city within a building that's hurricane-proof and can actually float (don't worry, it's tethered to something or other). Conceptualized through a mind trust of three architectural firms, green (wind, solar and water) energies would help power the structure's 20,000 residences, 1,000,000 square feet of commercial space, school, hospital and, just for fun, 3 casinos.
