Disastr is a simple, clear, logical proposal for evacuating whole cities in the event of terrorism or natural catastrophe. It is a last ditch sheltering solution for hundreds of thousands to tens of millions. We may never need this plan, but if we do, it may save lives one day. It relies on peer-to-peer disaster relief and commercial supply chains to provide housing, and the power of the network to coordinate relief efforts. There is an opportunity for a major tech company (Amazon, Google, Yahoo etc.) to provide this service using their redundant computer clusters.
Disastr has no official status, but has been positively reviewed by the American Red Cross and FEMA.
