They call it a house. We'd call it a pod. But no matter what term you use, the Ecocapsule is a self-sustaining shelter. Thanks to a built-in wind turbine, roof-mounted solar panels, and a high-capacity battery, there's no reason to connect it to the grid, while an intelligent rainwater and dew collection system works with built-in water filters to let you use pretty much any water source. Despite its small size, it can still hold two adults comfortably, with a folding bed, kitchenette, and even a toilet and shower.
