Nigeria’s Tuteria, Kenya’s Mobi-Water, Uganda’s Yaaka Digital Learning Network and South Africa’s GreenTower Microgrid have been selected as finalists for the Royal Academy of Engineering Africa Prize for Engineering Innovation for their engineering innovations which provide solutions to local problems.
From Nigeria, systems engineer Godwin Benson developed Tuteria, an online platform that links students to qualified tutors. Users can find tutors within their budget and location to teach them to play the piano, sew clothes, learn a new language and more. Tutors also cover a range of academic subjects for a range of ages.
Both students and teachers are thoroughly vetted before being allowed to use the service. The platform also has a rating system, and students book using an upfront online payment system, with the tutors paid once the lessons have been confirmed.
Yaaka Digital Learning Network
A Ugandan innovation, the Yaaka Digital Learning Network, also aims to bring education to those who can’t physically access learning institutions.
Developed by Africa Prize finalist Hindu Nabulumba and her team, Yaaka is designed like an interactive social network, where teachers and students can share academic knowledge and materials.
Students and teachers ranging from pre-primary school to university level share materials in the form of text, audio, audio-visual or video content. Online classes are held for those with internet-connected devices.
For those without internet access, an offline version has also been developed.
Addressing water challenges, finalist Kelvin Gacheru’s innovation is Mobi-Water, a smart solar-powered water monitoring system.
In Kenya, where 40% of urban and 60% of rural residents lack access to a safe and reliable water source, the water resource engineer designed the Mobi-Water system to enable water tank owners to monitor and control the water levels in their tanks from any location using their mobile phones.
Mobi-Water sends a text message alert to up to 10 mobile numbers when water levels drop below a certain point. Users can remotely open and close valves and pumps if they want to refill the tank or redirect the water.
The GreenTower Microgrid
Finally, South African rocket scientist Andre Nel’s invention tackles water and energy issues. The GreenTower Microgrid is a hybrid, solar microgrid solution that uses 90% less energy to heat water.
Only one-third of Africans have access to grid-connected electricity and heating water accounts for the majority of electricity costs in homes and offices.
A single unit of the GreenTower Microgrid packaged in insulated recycled shipping containers can service 15 homes, and reduce the electricity demand from a community by 65%, considerably easing the pressure on the national power grid.
The four finalists were selected from a pool of 16 shortlisted candidates from across sub-Saharan Africa, who all received six months of training and mentorship.
The winner will be announced on 23 May 2017 in Nairobi after pitching live to the judging panel and assembled audience. The winner receives £25,000, and £10,000 is awarded to each of the runners-up.
Previous winners of the Africa Prize for Engineering Innovation are Tanzanian Dr Askwar Hilonga, creator of the NanoFilter, and Cardiopad founder Arthur Zang from Cameroon.
The other 12 candidates on the 2016/2017 Africa Prize shortlist are:
- Achiri Arnold Nji (Cameroon) with the Traveler mobile software system, designed to monitor the speed, location and number of passengers on a bus and alert the driver and authorities to potential dangers.
- Alex Makalliwa (Kenya) developed Electric Tuk-Tuks and off-grid solar-powered charging stations to overcome poor grid connectivity, save Tuk-Tuk drivers on daily motoring costs and reduce CO2 emissions.
- Aline Okello’s (Mozambique) Rainwater Harvesting App helps users set up rainwater harvesting systems tailored to their area and rainfall patterns.
- Brian Turyabagye’s (Uganda) Mama-Ope smart jacket helps doctors identify pneumonia faster and more accurately.
- Edwin Inganji (Kenya) developed the Usalama mobile phone app to speed up the reaction time of Kenya’s emergency services.
- Fredrick Ouko’s (Kenya) Riziki Source is a web and text message-based platform which connects people with disabilities to jobs and employers.
- James van der Walt’s (South Africa) SolarTurtle is a mobile power station that provides instant electrification whenever it’s needed.
- Joel King’ori Kariuku (Kenya) developed the Sisal Decorticator, a mechanised peeler, which makes it more profitable for natural sisal fibre to be processed.
- Lawrence Ojok (Tanzania) designed the Green Rock Drill as a solar-powered alternative to modern fossil-fuel rock drills for small-scale artisanal miners. It is better for the environment and has an 18-month lifespan.
- Peter Mbiria’s (Kenya) E-Con Wheelchair can go off-road, climb up and down stairs and allows the user to stand upright while automatically navigating familiar terrain, and keeps its passenger perfectly level throughout.
- Sesinam Dagadu (Ghana) developed CodeRed, a logistics app that reduces emergency response times using a custom-made mapping system for urban areas that don’t have formal addresses.
- Dr Wilfred Fritz (South Africa) designed the Water&Solar100 lightweight portable solar cooker that tracks the sun automatically, has temperature and timing controls and even generates electricity to charge batteries.
