2023 Africa Prize for Engineering Innovation finalists
Chukwuemeka Eze, a Nigerian electrical engineer, developed the Revive Kit, a modular e-mobility service used to convert gas-powered three-wheeled motorbikes to run on rechargeable lithium-ion batteries.
Edmund Wessels, a South African biomedical engineer, has developed FlexiGyn, a battery-powered portable handheld device enabling gynaecologists to diagnose and treat a woman’s uterus without anaesthetic or expensive equipment, increasing women’s access to reproductive healthcare, particularly in remote areas.
Gibson Kawago, a Tanzanian electrical engineer, developed the Waga Pawa Pack, a rechargeable power source created from recycled laptop lithium-ion batteries, providing a reliable and affordable electricity source.
Anatoli Kirigwajjo, a Ugandan software engineer, developed Yunga, a local digital security network that connects neighbours to each other and police within a 20km radius via a physical device, smartphone app or SMS service, providing security at a low cost.
The finalists were chosen by the Royal Academy of Engineering, which founded the Africa Prize in 2014, after receiving support over eight months to help them accelerate their businesses.
The remaining 11 candidates from the 2023 Africa Prize shortlist are now eligible for the One-to-Watch Award worth £5,000, for which they will compete for the public’s vote at the Africa Prize final. The 11 One-to-Watch Award candidates are:
- Affordable AMD Solution, Boitumelo Nkatlo, South Africa - A technology to treat acid mine drainage (AMD) using industrial waste to recycle contaminated water for human consumption.
- Aquaset, Obed Zar, Ghana – A smart water management system that monitors water levels in boreholes and water tanks, regulating the rate at which water is pumped and preventing pump breakdowns and water waste.
