Cyclists know that you need to keep hydrated. And to make sure that you don’t run dry, industrial design student Kristof Retezár has designed a prototype self-filling water bottle. How? It turns air into water while you ride a moving bicycle.
Using the principle of thermoelectric cooling—where humid air passes through solar cells and condenses air moisture into water droplets—the water bottle is able to collect up to 0.5 litres of water within an hour. Of course that’s in countries that have the right climate.
“I wanted to bring a solution to many problems, including water scarcity,” Kristof said.
Kristof’s invention—called the Fontus—is designed as a handy bicycle accessory. It can be used for long bike tours and is also a good solution to water scarcity.
Kristof claims that the basic elements of the device aren’t too expensive. He estimated that the prototype costs between $25 and $40 to make. However, he notes that may change depending on future iterations of the water bottle. He eventually hopes to refine the device with a purification system. Thus allowing it to be used in cities with pollution. He’s also be looking into crowdfunding options and investors to mass-produce the device.
