This Bottle Can Turn Air Into Water.
So how does it work? According to a description of the product on the award site, solar panels generate the electricity needed to cool the upper chamber of the device, while the bottom heats up. As the bike moves forward, air is pulled in, and then slowed and cooled as it moves through that upper chamber. The moisture from the air then condenses into water and drips into a bottle.
Retezár sees potential applications for his device beyond the world of cycling. For example, a product like Fontus could be used to generate water in places where ground water is scarce or polluted, assuming the climate conditions were right.
"I wanted to bring a solution to many problems, including water scarcity," Retezár said.
