An architectural group from Slovakia is introducing their portable, egg-shaped, solar/wind-powered Ecocapsule at the Pioneers Festival in Vienna this month.
According to Lloyd Alter’s article on TreeHugger:
The designers claim that it “is fitted with all essentials necessary for a comfortable prolonged stay without a need to recharge or re-supply.” It has all the comforts of home: a tiny kitchen, a bathroom with toilet and shower. There is a pullout bed and lots of storage, all in a 4.468 m (14′ 7″) by 2.407 m (8′) egg with an area of 8 m2 (86 SF).
It’s powered by 2.6 m2 (28 SF) of solar integrated into the roof and a 750-Watt (42.65 BTUs/minute) wind turbine feeding a 4200-Wh battery bank. The shape is somehow optimized for rainwater collection, which is then filtered for use.
The designers characterize it as being suitable for a wide range of applications: from an independent research station or a tourist lodge to an emergency housing or a humanitarian-action unit.
