The Lexus Design Award 2021 has announced the finalists for this year. Amongst the cream of the crop is Henry Glogau’s ingenious contraption: a skylight that uses free sources of energy to light homes at night and distill seawater into safe drinking water.
This no-cost, clean energy solution can provide basic services for impoverished communities. The Solar Desalination Skylight works by evaporating seawater through the energy of the sun. During the day, seawater is fed through a pipe into the bowl-shaped skylight where solar power is used to distill the salty seawater. The skylight has a tap at the base of it to extract drinking water.
After the sun goes down, the residual brine left from the water purification process is used to generate an electrical charge to power the light.
There is a community in Antofagasta, Chile, where this brilliant invention is already being used. The design is affordable, practical, and takes advantage of free and clean energy sources.
Glogau’s Solar Desalination Skylight is up against a pretty impressive competition to win the Lexus Design Award 2021, but whether or not it is declared the winner, the skylight is already proving to have a great impact on the underprivileged communities.
