This egg-shaped capsule may look like something from outer space, but it’s being developed here on planet earth by Bratislava’s Nice Architects. The concept brings a micro shelter with an impressive array of sustainable technology that includes solar power, rainwater collection and filtration, and wind power. They plan to reveal a prototype in the next month, and make it available for sale later this year.

Inside you’ll find a cozy quarters of just 86 square feet. Designed to be easily transported, it can serve as a tiny house or office, and includes a toilet and shower, kitchenette, work and dining area, folding bed and storage both inside and out. Perhaps most exciting is the built-in technology it comes with, including a 28 square foot solar array and a silent 750 watt wind turbine.

Details are still fuzzy, though we expect to learn more once the firm makes its reveal on May 28 at the Pioneers Festival in Vienna.
