Science prodigy Cynthia Uwah, a Gr. 11 learner of the Calculus High School in Bloemfontein, has developed a device called the Ultimate Working Algae House.

This innovation has won her a gold medal at this year’s regional Eskom Expo held recently in Bloemfontein.

Cynthia’s unique device also qualified for exhibition at this year’s International Science Fair (ISF) to be held in Johannesburg from 3 to 6 October.

She is one of the 139 medal winners who will take part in the exhibition and she ended top of the 368 young scientists who attended the regional leg in Bloemfontein. Entrants from primary and secondary schools presented a wide range of themes, including alternative energy sources, environmental sustainability, health and medicine, water saving, recycling, and more.

The learners’ passion for the fields of science, technology, engineering, mathematics and innovation was on full display.

Cynthia said she was driven towards the project after learning that 72% of the greenhouse gasses causing global warming were carbon dioxide.

She does not hide her passion to have a cleaner environment and curb the effects of climate change on the planet.

Her device puts her on the right track to achieving this goal.

“The device utilises the photosynthetic characteristics of algae as a working tool to convert the carbon dioxide in the air into oxygen, thus assisting in reducing the current rate of global warming,” she said.
