Henry Glogau, a New Zealand-based designer, developed the Solar Desalination Skylight, an innovative solution aimed at addressing resource scarcity in coastal regions. This device utilizes solar energy to evaporate seawater, generating both light and potable water. The design works by directing seawater into a bowl-shaped skylight, where solar heat causes evaporation, transforming the salty seawater into clean, drinkable water. The leftover salt brine, an often-overlooked byproduct, is used to create energy that powers a soft diffused light, providing illumination during the night. This clever design is a finalist for the Lexus Design Award 2021, which celebrates solutions with a positive impact on humanity and the planet.
In addition to its practical application for drinking water and light, the Skylight is a low-cost, sustainable solution that addresses basic needs in places like coastal Chile, where access to clean water and energy is limited. By leveraging abundant natural resources—solar energy and seawater—Glogau’s creation offers an affordable and eco-friendly way to improve living conditions in vulnerable regions, where both water scarcity and energy poverty are prevalent​.
