These gorgeous twisty skyscrapers are 3D printed from desert sand

•, Michael Trei
Sand Babel is a desert city concept with several tall skyscrapers built using the material that surrounds them: sand. The towers are created using a massive solar-powered 3D printer, forming shapes that have been inspired by tornadoes and the mushroom rocks found in the desert. Each treelike structure is connected to the other buildings through a series of partially buried tubes that form the roots of the building, while the trunk contains housing for the residents.

The wide fluctuations in temperature normally found in a desert climate are leveraged to generate water using a giant condensation net at the top of each structure, while cooling is provided by a pair of double-helix tunnels that channel air under the building's base.
