After the Hurricane Katrina tragedy, designers and engineers began working together to developa plan to keep the residents of the Big Easy safe during times of flooding. One idea being proposed is a giant floating building called NOAH, which stands for New Orleans Arcology Habitat. The habitat boasts 20,000 residential units as well as 3 hotels and 500 timeshare units. Also housed within its triangular walls is loads of commercial space, 8000 parking spaces as well as cultural spaces, public works and schools. The idea is that you could live your whole life in NOAH if you so chose. In addition to using solar and wind power to support the structure, given its location on the water the building would also use water turbines to generate power. No doubt it would be quite the floating structure…if it is ever built!
