If you are a cyclist, you are familiar with the feeling of anxiety that arises when you start running out of water in the middle of a ride: there are still several kilometers to go home, and the risk of dehydration increases significantly. Fortunately, the invention of student designer Christoph Reitzaar will save you from both dehydration and unnecessary worries. Christoph has developed a device that attaches to the bicycle frame and uses solar energy to convert moisture in the air into drinking water in your bottle. The secret of the new device lies in the use of thermoelectric cooling. Solar panels generate energy, which is used to cool the top part of the device, where the air enters during the bike ride; the moisture condenses and flows into the bottle. The bottom part remains warm, which only accelerates the condensation process. Continue reading →
