This giant water drop is solar powered and offers cool water where it is scant
There is a fear that the not-so-distant future may be waterless. This acute shortage may have inspired something in the design of the WaterDrop, a conceptual solar-powered drop. The idea has been conceptualized by Ap Verheggen. The WaterDrop employs condensation to create water out of air by leveraging sunlight, which is commonplace in most ‘warm’ regions. “If temperatures rise, the air contains more water,” Ap said. “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 outside of the WaterDrop is equipped with photovoltaic modules that absorb solar energy that is then used to cool air to produce condensation. A fan is also powered up in the process to create airflow. Ap plans to add small rocks to the system so as to gain necessary minerals.
