The young engineers making tools for their communities

Some engineers dream of skyscrapers and rockets. Others dream of something closer: a better way to test for malaria in their village, a cheaper way to power their school, a smarter way to keep vegetables fresh at the market.

Across Africa, young engineers are building tools for the people around them. They often start with limited money, borrowed equipment and a lot of persistence. What they build may not always make headlines — but it changes daily life.

Who are the young engineers making tools for their communities, and what can we learn from their journeys?

Why young engineers matter

Africa faces big challenges — energy access, health care, water, food security, climate change, transport. It also has the world's youngest population. Young engineers are uniquely placed to solve local problems because:

• They know the problems first-hand.
• They grew up with mobile phones and the internet.
• They're willing to try new approaches.
• They'll live with the results for decades.

But Africa also has a shortage of engineers. UNESCO's Engineering Report has highlighted that many African countries have far fewer engineers per capita than they need for infrastructure and development.

The Royal Academy of Engineering's Africa Prize has supported well over 100 African innovators from many countries since 2014, with many alumni creating jobs and serving thousands of customers. (Royal Academy of Engineering) Programmes like this show what happens when young engineers get training, mentoring and funding.

Brian Gitta: a malaria test without needles

Brian Gitta, from Uganda, had malaria several times as a student. Each time, diagnosis required a blood test — a finger prick, a lab, waiting. He and his team asked: could we test for malaria without drawing blood?

They developed Matibabu, a low-cost device that uses light and a magnet to detect malaria-related changes through the skin, connected to a smartphone. In 2018, Gitta became the youngest winner at that time of the Royal Academy of Engineering Africa Prize for Engineering Innovation.

The lesson: personal frustration can be the start of innovation. Gitta didn't start with a business plan. He started with a problem he had lived.

Like all medical innovations, such devices need long testing and approval before wide use — a reminder that engineering for health requires patience and evidence.

William Kamkwamba: power from scrap

In Malawi, a teenage William Kamkwamba built a wind turbine from scrap — a bicycle frame, a tractor fan and PVC pipes — using diagrams from a library book. It powered lights and, later, a water pump for his family's farm during hard times.

His story, told in "The Boy Who Harnessed the Wind," shows what engineering is at its heart: understanding a need and using what's available to meet it. Read more in African makers who teach what they know.

"I try, and I made it." — William Kamkwamba, describing building his windmill (TED talk, 2007)

Arthur Zang: a heart test for rural areas

Cameroonian engineer Arthur Zang developed the Cardiopad, a medical tablet that lets health workers in remote areas carry out heart tests and send results to cardiologists far away. It answered a real gap: very few heart specialists, mostly in big cities.

His journey from a young engineer with an idea to an award-winning innovator is described in more detail in From a classroom robot to a local solution.

Other young engineers to know

Across the continent, many young innovators have been recognised for tools that serve their communities. Examples include:

• Innovators in the Africa Prize network working on solar cold storage for farmers, affordable prosthetics, water filtration, clean cookstoves and agricultural sensors.
• Kelvin Doe (Sierra Leone), who built batteries, a generator and a community radio station from scrap as a teenager.
• Student robotics teams across Africa, including Team Benin at the FIRST Global Challenge, designing solutions around global challenges. See Team Benin au FIRST Global Challenge 2026.

Many of these engineers share a pattern: they started small, used what they had, and kept improving.

Joke break: Ask any young engineer how their first prototype worked. The honest answer is usually: "Perfectly — in my room, at night, when nobody was watching. The moment I showed it to someone, it caught fire." Every inventor has a story like this. The good ones keep a fire extinguisher nearby.

What these engineers have in common

Looking across these stories, patterns appear:

Not "I want to build something cool," but "People in my community suffer from this."

• They started with a real problem

Scrap, second-hand parts, shared workshops, library books, free online resources.

• They used what was available

Every successful device went through many versions.

• They tested and failed — a lot

Teachers, engineers, programmes like the Africa Prize, university labs, maker spaces. (See Why local mentors can change a young person's future.)

• They found mentors

Competitions, media coverage and talks helped them get funding and partners.

• They told their story

Cost, ease of use, repair and local conditions mattered as much as clever design.

• They thought about users, not just technology

The barriers they face

It's not easy. Young African engineers commonly face:

• Lack of funding. Early-stage money is hard to find.
• Import costs. Electronic components can be expensive and slow to import.
• Limited equipment. Few well-equipped labs and workshops.
• Regulation. Medical and electrical devices need approval, which takes time and money.
• Brain drain. Some talented engineers leave for opportunities abroad.
• Scepticism. Some customers trust foreign brands more than local inventions.

What helps: programmes and spaces

Several types of support help young engineers:

• Prizes and fellowships: The Royal Academy of Engineering Africa Prize, the Africa Innovation Foundation's Innovation Prize for Africa, and national competitions.
• Maker spaces and fab labs: shared workshops with tools. (See African makers who teach what they know.)
• University labs and incubators.
• School clubs and competitions: robotics and science fairs. (See How to start a school robotics club with one kit.)
• Online learning: free courses in electronics, coding and design.

How you can support young engineers

• Buy and use local innovations when they're safe and good.
• Offer mentorship if you have technical or business skills.
• Share their stories on social media.
• Donate tools or components to schools and maker spaces.
• Invite them to test solutions in your business, school or organisation.
• Encourage girls: engineering needs everyone. See The women building new paths into science.

How to start if you want to be one

If you're a young person dreaming of engineering:

• Learn the basics: maths, physics, coding.
• Build small projects at home with cheap components.
• Join a club, maker space or online community.
• Look around for problems: write them in a notebook.
• Pick one and build a rough prototype.
• Show it to people who have the problem. Listen.
• Improve, then enter a competition or fair.

Remember: you don't need permission to start. You need curiosity and persistence.

Frugal innovation: doing more with less

Many young African engineers practise what researchers call "frugal innovation" — creating good solutions with limited resources. The idea was popularised in the book "Jugaad Innovation" (Radjou, Prabhu and Ahuja, 2012), which looked at inventors in India and other emerging markets who designed affordable, simple, robust products.

Frugal innovation principles:

• Use local, available materials.
• Keep designs simple and repairable.
• Focus on the core need, skip unnecessary features.
• Design for tough conditions: heat, dust, bumpy roads, unstable power.
• Keep costs low enough for local customers.

This isn't "cheap engineering." It's smart engineering. A solar lamp that survives a fall, a water pump that local mechanics can repair, a medical device that runs on batteries — these can be more valuable than expensive high-tech tools that break down in real conditions.

A day in the life (illustrative)

Consider an illustrative young engineer in Abomey-Calavi we'll call Ifè (illustrative). She studied electrical engineering and now builds solar-powered cold boxes for fish sellers.

Morning: She visits the fish market at Cotonou's lagoon to check how two prototype boxes performed overnight. One kept fish fresh; the other's battery drained early. Midday: She rewires the second box and adjusts the insulation using a cheaper local material. Afternoon: She meets a microfinance officer to discuss letting sellers pay for boxes in small weekly amounts. Evening: She teaches three apprentices how to repair the boxes' charge controllers.

Her work combines engineering, business, teaching and listening. That's what community engineering looks like in practice.

Engineering with empathy

The best engineering isn't only about clever machines. It's about empathy — understanding people's lives and needs. The young engineers in this article didn't just ask "What can I build?" They asked "Who needs help, and how can I help them?"

That question will shape Africa's future far more than any single invention.
