# Solar-Powered Water Bottles The Fontus Self-Filling Water Bottle Uses Water Harvesting Methods By Alyson Wyers | Published 2014-10-22 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/selffilling-water-bottle References: [psfk](http://www.psfk.com/2014/10/self-filling-water-bottle-cycling.html) & [jamesdysonaward.org](http://www.jamesdysonaward.org/projects/fontus-2/) This self-filling water bottle was built for your bike. The [solar-powered invention](https://www.trendhunter.com/trends/floating-solar-still) takes moisture in the air and turns it into drinkable water. Designed by Kristof Retezar, Fontus can collect up to half a liter of water in one hour in ideal climate conditions, or a constant flow of one drop a minute. Based out of Vienna, the industrial designer was inspired by the 2 billion people in over 40 countries who do not have access to clean water. The method of [water harvesting](https://www.trendhunter.com/trends/the-kara-pure-2) is an old one practiced for over 2000 years. Retezar explains his aim to make a self-filling water bottle as "a small, compact and self-sufficient device able to absorb humid air, separate water molecules from air molecules and store water in liquid form in a bottle." ## Trend Insights (Trend Hunter) - Score: 6.3/10 - Popularity: 88% | Activity: 93% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Gen Z, Millennial, Gen X - Top markets: Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### Key Themes Behind This Trend - **Solar-powered Drinking Water:** Innovative water bottles that use solar power and collect moisture from the air provide opportunities for disrupting the traditional bottled water market and promoting sustainable practices. - **Water Harvesting Technology:** Water harvesting technology can be integrated into a variety of products and industries to collect and purify water, providing opportunities for disrupting traditional water management methods and promoting sustainability. - **Access to Clean Water:** Innovations in collecting, purifying, and distributing clean water can have a significant impact on communities without access to clean water, creating opportunities for disrupting the traditional aid and development industry. ### Where This Applies - **Beverage Industry:** The solar-powered water bottle and other innovative water products offer opportunities for disrupting traditional bottled water and beverage companies, promoting sustainable practices. - **Outdoor Industry:** The Fontus self-filling water bottle and other water harvesting technologies offer opportunities for disrupting traditional outdoor gear and equipment companies. - **Aid and Development Industry:** Access to clean water is a significant issue in many areas of the world, and innovations in water collection, purification, and distribution can disrupt traditional aid and development approaches. ## Related on Trend Hunter - [Self-Cleaning Water Bottles](https://www.trendhunter.com/trends/halo-smart-water-bottle.md) - [Accessible Atmospheric Water Dispensers](https://www.trendhunter.com/trends/water-from-air.md) - [Customized Smart Water Bottles](https://www.trendhunter.com/trends/ocean-bottles.md) - [Self-Refilling Coffee Machines](https://www.trendhunter.com/trends/kara-pod.md) - [Drinking Water Home Appliances](https://www.trendhunter.com/trends/atmospheric.md) - [Five-in-One Water Filter Bottles](https://www.trendhunter.com/trends/vitaloop-water-filtration-bottle.md) - [Pure Drinking Water Systems](https://www.trendhunter.com/trends/spout-water.md) - [Bacteria-Killing Water Bottles](https://www.trendhunter.com/trends/uvc-selfcleaning-water-bottle.md) - [Portable Water-Carbonating Canteens](https://www.trendhunter.com/trends/sparkling-water-bottle.md)
