It's a modern day Noah's arc, a luxury shelter fully equipped with everything from an entertainment theater to an exercise room. If you can fork up between $25,000 to $50,000, this could be your home away from home should disaster strike.
Robert Vicino says business is booming. His company, The Vivos Group, is in the process of building seven shelters around the country and one in Europe that is expected to be the size of Wal-mart .
"Our goal is to accommodate 6000 people worldwide by 2012," he tells CNBC. "That's only one in one million people so we're not even scratching the surface with the potential here."
The shelters are buried 25 to 50 feet below the earth's surface so they can withstand a 50 megaton nuclear blast within a 10 mile radius, biological and chemical attack, earthquakes and tsunamis.
