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. it's really a simple, age-old process.
