Portable solar device creates potable water
The Solarball, developed as Mr Jonathan Liows final year project during his Bachelor of Industrial Design, can produce up to three litres of clean water every day. The spherical unit absorbs sunlight and causes dirty water contained inside to evaporate. As evaporation occurs, contaminants are separated from the water, generating drinkable condensation. The condensation is collected and stored, ready for drinking.
Liows design was driven by a need to help the 900 million people around the world who lack access to safe drinking water. Over two million children die annually from preventable causes, triggered largely by contaminated water. It is an increasing problem in developing nations due to rapid urbanisation and population growth.
Mr Liows simple but effective design is user-friendly and durable, with a weather-resistant construction, making it well suited to people in hot, wet, tropical climates with limited access to resources.
The challenge was coming up with a way to make the device more efficient than other products available, without making it too complicated, expensive, or technical, Mr Liow said.
