Lexus Design Award announces its Grand Prix winner for 2021, the ‘Portable Solar Distiller’





Earlier today, Lexus Design Awards announced their winner for the 2021 edition of their award program on April 27th. The winning project ‘Portable Solar Distiller’ by Henry Glogau was declared the Grand Prix Winner, surpassing 2,079 other design entries from 66 countries. Chosen as the project that best encompasses “Design for a Better Tomorrow”, the Portable Solar Distiller provides clean drinking water by filtering polluted water or overly saline sea water using sunlight. Merging local resource production with community architecture, this low-
tech solution also serves as a shaded gathering place.

The ‘Portable Solar Distiller’ was selected as the Grand Prix Winner from a roster of 6 finalists. Initially named the Solar Desalination Skylight, the design went through the mentorship phase under the expertise of Joe Doucet, Sabine Marcelis, Mariam Kamara, and Sputniko! These four world-class creators guided the finalists in surmounting challenges, helping refine and define the project and bring it to a fully refined stage. The 6 finalists were judged by an elite jury panel comprising Paola Antonelli, Dong Gong, Greg Lynn, and Simon Humphries, the elite panels who judged the entries. After selecting the Grand Prix winner, Judge Greg Lynn commented that “The winner was one of the designers who surprised me the most from the application to the final submission. The consistent mission of the winner persisted while the transformation in scale and social function was exemplary. The design became more refined, more functional and more open-source during the [mentorship] process”. Senior Curator at MoMA and Judge of the Lexus Design Award 2021, Paola Antonelli added, “It is heartening, after a year of isolation and “suspension,” to see that designers are still so firmly focused on the widespread issues connected to the environmental crisis. Our Grand Prix Winner tackled water shortage in exquisite low-tech fashion, using universal technologies that make it scalable and deployable worldwide.”

The Portable Solar Distiller by Henry Glogau aims at providing communities with easy access to fresh drinking water by relying on a highly-effective yet low-cost filtration method using sunlight. Its large canopy serves a dual purpose – harvesting sunlight to help purify water through evaporation, and acting as a community center for people to gather under during the day or even at night. The Portable Solar Distiller’s open-source schematic can easily be tweaked and implemented by anyone, allowing the design solution to have a wider reach and impact. The Portable Solar Distiller is designed in a way that can be carried, opened out, and assembled anywhere. Almost like a beach umbrella, it provides shade for groups of people, while having the added benefit of being able to purify water. The un-drinkable water goes into the canopy on the top, and heat from the sun causes the water to evaporate. Pure drinking water condenses on the upper part of the canopy, trickling down into a jerry can that fills up over time, giving people fresh water that can be consumed or used to cook food. Aside from providing free drinking water, the portable nature of the solution and its ability to create community gathering areas under the shaded canopy are what make the Portable Solar Distiller such an effective design that delivers on the promise of a ‘better tomorrow’.

Portable Solar Distiller by Henry Glogau

A holistic approach to providing coastal informal settlements with water, energy and natural light. The design utilizes abundant solar energy and seawater to create a Portable Solar Distiller. It emits a natural diffused light, produces drinking water, and utilizes leftover salt brine for energy creation.

Testing was done within an informal settlement home over a one-month long expedition to Antofagasta, Chile. Over a 12- hour period the prototype could produce 540 ml of purified water, with a reduction of salinity levels from 36,000ppm (parts per million) down to 20ppm.

Salt brine waste from the evaporation process is further used to create a source of energy through a reaction when placed in storage tubes holding copper and zinc. These 12 salt batteries provided 9.53 volts, powering a LED light strip during the night and charged by a mini solar panel during the day.

As well as the functional performance, the desalinated water adds a morphing dappled effect that changes mood throughout the day, creating a soft ambiance for the living room space where family activities take place.

This innovative skylight uses light from the sun to purify drinking water

What if the sun could purify our water? What if it didn’t require human intervention or energy? What if this low-cost solution could empower coastal regions with an abundance of saline water but minimal access to drinking water? Designer Henry Glogau’s Solar Desalination Skylight knocks multiple proverbial birds with one stone. It serves as a no-cost lighting solution for low-income households, while also using the sun to desalinate drinking water.

The Solar Desalination Skylight is a finalist of the LEXUS DESIGN AWARD 2021. Currently in their 9th year, the Lexus Design Awards are on a mission to ideate and innovate for a better future for humanity as well as for the planet. With their underlying theme of “Designing for a Better Tomorrow”, the awards program looks at solutions that have a uniquely positive impact on society, humanity, and in the process, to reward a new generation of designers for their impactful ideas. The Lexus Design Award’s core objective has always been to foster great ideas and great talent. Creating the perfect environment for a design to grow, LEXUS helps engineer ideas into real, impactful solutions. Apart from accelerating, developing, and promoting design projects, the Lexus Design Award helps kickstart design careers too, with exclusive mentorships from international design stalwarts like Joe Doucet, Mariam Kamara, Sabine Marcelis and Sputniko!, as well as funding for prototypes (up to 3 million Japanese Yen or $25,000 per project) and the opportunity to have your work judged by the biggest figures in design in the final Grand Prix competition. This year’s judges include Paola Antonelli (Senior Curator at MoMA), Dong Gong (Founder and Principal Designer at Vector Architects), Greg Lynn (Architect and CEO at Piaggio Fast Forward), and Simon Humphries (Head of Toyota and Lexus Global Design).

Needless to say, the Solar Desalination Skylight’s purpose aligns perfectly with the awards’ theme of Designing for a better tomorrow. The design uses free and abundant solar energy and seawater to create a diffused light as well as clean, potable freshwater. The residual brine in the purification process is further used as chemical energy to power the diffused light after nightfall. The result is a design that’s cheap, impactful, and makes brilliant use of the resources at its disposal. Seawater is fed through a pipe into the chandelier-shaped skylight. Aside from illuminating interiors, the design uses energy from the sun to distill the salty seawater, which is accessible through a tap at the very base of the skylight. At night, the residual saltwater is used to generate an electrical charge which powers the light, creating a closed-loop that uses abundant resources to their maximum extent to benefit humanity.

The Solar Desalination Skylight is one of the six finalists of the LEXUS DESIGN AWARD 2021. Stay tuned as we feature all the finalist designs following the Grand Prix Winner Announcement here on Yanko Design!
