Water is hard to find in the desert, so designers Bartłomiej Gowin and Tomasz Janus created a giant tower called the 'Hydro Aero Device' to collect moisture from the air. The Hydro Aero Device is a massive skyscraper that works sustainably to harvest a steady source of water from the air around it.
The building works by condensing moist air on cold tubes. That condensation then trickles down to a central tank through canals. Water in the tank can then be distributed to residents of the tower or to the surrounding community. This process is powered by piezo-electrical strips that generate energy from wind friction.
To further conserve water, the tower recycles liquids used by inhabitants. Greywater is filtered and then stored separately for reuse.
