The “WaterDrop” of the solar researcher Ap Verheggen comes with promises of a better future.
Basically, the “WaterDrop” is a handheld solar-powered condensation device that produces cool drinking water.
In the words of Verheggen himself:
If temperatures rise, the air contains more water. Normally, higher temperatures also mean more sunshine. So, why not focus on harvesting water out of the air, powered only by renewable solar energy? In this way drinking water and water for agriculture become available in most dry parts of the planet.
The photovoltaic modules on the exterior absorb solar energy during the day. And then this energy is used to cool the air and produce condensation, while also powering a fan to create airflow. The result is drinking water which is collected in a small cistern.
