Kristof Retezár, an industrial designer in Austria, designed this clever gadget called Fontus. When it's humid, the system draws water out of the air and pours it into a water bottle. It mounts on a bike frame, so if you're biking in swampy weather, you could use it to supplement your water supply.
Solar cells power the unit, which cools the top and heats the bottom. Perforated walls inside collect moisture, which flows down a tube into the bottle. It can produce roughly one drop of water per minute.
