Just when I thought that no one could dream up or think of the dumbest thing possible, life surprised me. The above link is to a floating city for the rich to travel the world in a self contained vessel. It's the new Titanic everyone!!
I am so stunned that I cant bag on it, I got material for ten years if I start. I know that if it was possible to colonize the moon in my lifetime I would go in a heartbeat knowing full well the hardships, but on an over priced yacht? The guy who is selling this idea is either the biggest whack job or the worlds greatest salesman.
