Can't afford to build your hardened, underground bunker for the cyber-zombie-alien apocalypse? It's a problem a lot of us have. That's why you should try this model, made entirely from recycled shipping palates.
Over at Inhabitat, they're calling this the "Slumtube" - it was invented by Andreas Claus Schnetzer and Pils Gregor, two designers in Johannesburg, where the summer can be stifling and the winters bone-chilling. This hangar-like structure is well-insulated for heat and cold, and is made of cheap materials you can steal from any abandoned shipyard after most of humanity has perished.
When the cyber-zombie-aliens attack, you can install recycled prison bars as a barrier and set a bunch of these tubes up in a circle with your farm in the center. You stay snug, but most forms of hostile (un)life are out in the cold!
