Biking cross-country through rough terrain may mean that access to fresh, drinkable water may be limited. But what if there was a device that could "pull" moisture from the air and transform it into drinking water? That's the idea behind Austrian designer Kristof Retezár's Fontus, a "self-filling" water bottle that can make water out of thin air.
The solar-powered bike accessory uses a Peltier Element to generate water. It's essentially a cooler with two chambers that facilitates condensation, and takes in air as the bike moves, which is then slowed and cooled down by barriers that allows it to condense and form water, which is channelled and collected in the bottle.

Uh, most of the world does not regularly experience 50% humidity and 20 C conditions.
Basically, this is a dehumidifier in a bottle. Plug one in and see for yourself how much water the air in your area is capable of producing (perhaps divide by a constant factor of 2 to simulate efficiency loss from size).
