The show "The Colony" on the Discovery Channel is about a Group of 15 people who try to survive a post Apocalyptic world for 10 weeks. The Experiment has them located in a Warehouse by the LA River with no power grid and occasional bandits to threaten their way of life.
Most of everything they use to survive comes from their hands and their creativities and experiences.
I just wanted to mention the show, because it's probably the only educational reality show on TV and it's very ERE focused while the Audience itself doesn't realize it.
These 15 people get together and survive in almost luxury at the end just fine for 10 weeks with their innovations and self created self-sustaining systems! So why not just live that way for a lifetime?
