HelioWater domes use solar power to produce clean drinking water

could solar powered spheres solve the clean water crisis?

In 2019, UNICEF and the World Health Organization published a report that revealed 1 in 3 people globally do not have access to safe drinking water. In response to this staggering statistic, designers and inventors around the world are developing novel ways of accessing clean water. The latest idea comes in the form of HelioWater, a French company conceived by Marine Tech. Composed of large spheres mounted onto a metal frame, the HelioWater device relies on a large solar panel at its basis to power the purification process. The company says each module of 1 sqm produces 10 liters of water per day.

How does HelioWater work?

The HelioWater method is completely autonomous and works using evaporation, condensation and mineralization. Seawater is pumped into the sphere, where it evaporates and condenses onto the inside surface of the top dome. Clean drinking water then drops to the bottom and is pumped away.

The components are made using recyclable materials that are resistant to adverse weather. All the equipment is delivered in a box to make it easy to transport, and it’s also quick and easy to install and operate. Furthermore, the single modules can be grouped together to cater for larger needs. The company thinks that HelioWater could be the ideal solution for disaster relief and refugee camps, where available water may be unsafe for human consumption.
