Solar power will give you non-stop water during bike rides
If you're a cyclist, you know the anxiety that comes with running out of water in the middle of a bike ride -- the last thing you want is dehydration when you're miles away from home. Design student Kristof Retezàr may just set your mind at ease, though. He recently developed Fontus, a bike-mounted device that uses solar power to convert air moisture into water for your drinking bottle. The key is its use of thermoelectric cooling. Solar panels generate electricity that cools the top of the device, where air comes in as you ride; as the moisture condenses, it drips water into a bottle below. The bottom stays warm, but that only accelerates the condensation process above.
