Two brilliant teenagers from the Free State province discovered a way to generate water from cow dung.
Mookgo Mofokeng and Reatlehile Sekaja are both 17 years old doing grade 12 at Beacon Secondary School in Qwaqwa, SowetanLive reports.
They made their discovery in 2016 and showcased it at the recent Eskom Expo for Young Scientists, Briefly.co.za learned.
The two girls won gold medals for their discovery at the Expo, which was held in Ekurhuleni from 3 to 5 October, 2018.
They explained that water for farming is scarce in their area and this inspired their innovation. They designed a dewatering machine which extracts the water using pipes and a suction system.
Mofokeng explained that they are able to extract 800ml of water from 1kg of cow dung. She added:
This water is also very good for plants as they grow much faster because it acts as a fertiliser. The water can still go for purification.
Over 500 students from South Africa and around the world participated at the Expo. They won medals, cash prizes, bursaries, and laptops for their impressive innovations.
