For some reason or another, these have been a rash of "end-of-the-world" movies over the past few years. While those living-dead proof, fully armored vehicles will likely never be anything but a fantasy, the Nomad RV should offer everything you need to keep you and your family safe.
Nomad RV Fog Trap
The basic idea here is that the survivors will have to return to a nomadic lifestyle, moving from place to place to find food and water. The Nomad RV will make this lifestyle easier by offering a place to grow food, a system to purify water and a solar array to provide power for both.
A large sail, presently being dubbed a fog trap, will extend from the top of the Nomad to accumulate moisture from the air. This will then be collected and used for drinking and cooking. A greenhouse has also been incorporated to provide a place to grow vegetables and other plants.
According to the designer, a family of four can live and work comfortably inside the Nomad RV for quite some time, assuming no unwanted guests stop for a visit.
While I wouldn't count on seeing the Nomad RV reaching production anytime soon, it's still fun to speculate. EcoFriend
