Energy - cooling system works on gravity instead of electricity

gravity-powered cooling system that extracts water from the air without using electricity

New cooling system works on gravity instead of electricity - Super InnovatorsSuper Innovators

Summary:

New slippery surface on water-collectors releases pinned water, which drops off under gravity, unlike earlier systems which need electricity. Extracts water from air. No moving parts, so very low maintenance requirements

Potential Applications: irrigation, washing, cooling buildings on which solar cells are based
