SOLARBALL / Water Purifier
Dyson Award finalist; Featured on ABC, CNN and BBC. Currently on display in the ROCA Gallery, London

Water. It’s something we often take for granted. However, 1 in 8 people in our world don’t have access to clean, drinkable water. This is the cause of nearly 80% of all sickness and disease in third world regions.

The Solarball is a personal and portable water purification device, capable of producing potable water out of contaminated water. The device can produce up to 3 litres of clean water daily, by absorbing heat from the sun, causing dirty water contained inside to evaporate. As evaporation occurs, contaminants are separated from the water - generating drinkable condensation.

The lower half of the Solarball is insulated by a pocket of air - allowing the dirty water inside to absorb and retain heat more efficiently. Dirty water can be inserted (from the top) and clean water dispersed (from the front) without the need to take the device apart. This reduces significant heat loss whenever water needs to be inserted or dispersed - increasing the speed at which evaporation takes place.

Full-scale, functional prototype manufactured out of PMMA acrylic and polypropylene.
