Youthful, Vienna based start-up firm, Fontus, has actually transformed the canteen. The technology, which is solar powered, uses a thermoelectric cooling system to lead to condensation which will, in time, fill out the attached water bottle.
As Inhabitat points out, “After over 30 experiments, Retezár was able to calibrate Fontus to achieve a steady output of one drop of condensed water per minute. Given the right conditions, the device can harvest as much as a half liter of water in an hour. Although this is an impressive achievement, it is not sufficient for a hot, humid day. The Fontus is also ineffective in urban areas, where pollution contaminates water molecules pulled from city air.”
Fontus has developed two different self-filling bottles: The Airo for hikers, and the Ryde for cyclists. Fontus joins many promising projects in the quest to harvest water from air. In 2013, MIT scientists created a special mesh material that pulls water from fog and the results so far have been encouraging.
Perhaps the professors could stitch an on-campus water-capturing web that might spare Boston of its wicked humidity. More importantly, these technologies could allow for a substantial decrease in water insecurity, which could alleviate poverty and serve as a resilient climate change adaptation.
So this isn’t yet a viable choice for city dwellers, yet perhaps future versions will include a filtration system, allowing the bottles to be used in any kind of atmosphere. With the ideal renovations, these water bottles could be game-changers in everything from armed forces usage to impoverished areas without access to drinking water.
