Imagine a water bottle on your bike that was self-filling. That is what Kristof Retezár hopes to create with his Fontus water bottle. The idea is simple enough; the water bottle uses solar cells to create an electrical temperature change which creates condensation. The condensed water is then stored in the water bottle for drinking. Sounds good at first glance but it seems to only create one drop of water per minute.
After more than 30 experiments, I finally achieved a constant drop-flow of one drop of condensed water per minute. After developing a functioning inner system, I designed a compact and practical hull which can be easily attached to a bicycle, integrates the water bottle and can be comfortably handled.
Maybe they can figure out a way to increase the fresh water output. Either way, they did create a fancy video (after the break).
