A couple of enterprising Kenyan engineering students are showing how mobile phones are an inventor’s dream. Their two inventions – one a way to re-charge phones while bicycling, the other an aid for catching fish – show the potential for adapting this technology to the needs of the poor.
The rapid spread of mobile phones across the South is giving rise to a flurry of invention and experimentation. While many of the new mobile phone-users do not have much money, they are often driven by poverty to invent solutions – and in so doing prove the phones offer many ways to generate income.
According to the International Telecommunications Union (ITU), Africa is the world’s fastest-growing mobile phone market, and the number of subscribers surpassed 300 million in 2008. The number of mobile phone users in the world passed 4 billion in 2008, and the fastest growth was in the South (ITU). The trend towards increasing development of inexpensive handsets means more phones will be reaching even more poor people in the future.
Kenya has seen blistering growth in mobile phone ownership: from just 200,000 users in 2000, there are now more than 17.5 million people with mobile phones out of a population of 38.5 million
As powerful as mobile phones are, they need electricity to keep working. The struggle to find a steady supply of electricity vexes many in the South, so finding cheap or free ways to recharge the phones represents a huge market opportunity.
While mobile phone recharging has become a business in its own right across the South, it is costly as well as time-consuming. Some people spend hours just getting to recharging stations.
To tackle this chronic problem, Engineering students Pascal Katana and Jeremiah Murimi of the Department of Electrical and Information Engineering at the University of Nairobi, Kenya (http://uonbi.ac.ke/departments/index.php?dept_code=HE&fac_code=32) have invented a device called the “smart charger.” It is powered by the dynamo that is standard issue with most bicycles sold in Kenya. Dynamos on the bicycle’s back wheel are little electricity generators that use pedal power to illuminate the bike’s lights.
It takes an hour to charge the mobile phone by peddling the bicycle: around the same time it takes to charge a phone using an electricity plug. A one-time charge for somebody can cost up to US $2 at a recharging service. But the smart charger sells for 350 Kenyan shillings (US $4.50) – around the cost of two charges.
“We both come from villages and we know the problems,” Murimi told the BBC.
“The device is so small you can put it in your pocket with your phone while you are on your bike.”
The smart charger has been assembled from bits and pieces the duo found: “We took most of (the) items from a junk yard,” Katana said. “Using bits from spoilt radios and spoilt televisions.”
To test the experimental device, workers at the university campus were recruited to have a go.
“I use a bicycle especially when I’m at home in the rural areas, where we travel a lot,” said campus security guard David Nyangoro. “It’s very expensive nowadays charging a phone. With the new charger I hope it will be more economical, as once you have bought it, things will be easier for you and no more expenses.”
Kenya’s National Council for Science and Technology (http://www.ncst.go.ke/) has now backed the project and the students are exploring ways to mass-produce the smart charger.
Another invention by Katana has adapted a mobile phone to improve fishermen’s success, according to Afrigadget (www.afrigadget.com). It amplifies the sounds made by fish as they feed. As the sound is broadcast outwards from the feeding, other fish are attracted to the same place, believing there is more food. A GPRS/GSM (http://en.wikipedia.org/wiki/General_Packet_Radio_Service) mechanism in the fishing net is triggered when there is enough fish in the net, and an SMS text message is sent to the fisherman letting him know it is time to haul in the net.
It looks like Pascal Katana can re-charge your phone and fill your plate!

The East African nation of Kenya has become synonymous with high-quality agricultural products, and offers lessons for other countries across the South. The country has been able to combine innovation in new technologies (it is a pioneer in mobile phone applications like m-banking), with quality control for its products like the Coffee Kenya Brand logo (http://www.coffeeboardkenya.org) and ease of access to information on Kenyan products and resources via the internet – crucial to drumming up international business – like the SME Toolkit Kenya (http://kenya.smetoolkit.org/kenya/en) .
There are several advantages to improving standards and productivity in agricultural products in Africa. The first is regional: greater productivity and efficiency will help in reducing malnutrition and food crises that have plagued the continent for decades. Secondly, it also allows Africa to export food to other countries with fast-growing economies and boost the continent’s wealth.
The dramatic changes taking place in African countries – especially rapid urbanization that has made the continent home to 25 of the world’s fastest growing cities (International Institute for Environment and Development) – means there is an urgent need to increase food production and stabilize rural economies to support farming.
Kenya is considered home to one of the continent’s most successful agricultural production zones, with multiple agricultural products and brands developing a solid global reputation for quality.
The country benefits from the fertile Great Rift Valley (http://en.wikipedia.org/wiki/Great_Rift_Valley) , where the country’s biggest crops – tea and coffee – are grown.
Agriculture is a key part of Kenya’s economy: 75 percent of the working population is employed in the sector. Farming sits behind tourism as the country’s second biggest contributor – 20 percent – to the gross domestic product (GDP).
Kenya has had a great deal of success with fruits, vegetables and flowers (Kenyan flowers are a mainstay of many European supermarkets). Kenya has been able to achieve this by using well the 10 percent of the country’s land that is suitable for farming.
Around Mount Kenya (http://en.wikipedia.org/wiki/Mount_Kenya) , the cool and wet climate is perfect for farming tea, coffee, flowers, vegetables, corn and sisal. Other products that have been successfully grown include sugar cane, pineapple, cashew nuts, cotton, and livestock-related products – dairy goods, meat, hides and skins.
Kenya’s main export markets are the United Kingdom, the Netherlands, Pakistan and the United States. This agricultural export success has had a knock-on effect of reinforcing a global reputation as one of Africa’s best countries for business.
In the tea market, James Finlay and Williamson have a strong reputation and sell to major supermarkets in the UK.
Another successful tea company is Kenya Tea Packers Limited (Ketepa) (http://www.ketepa.com) . A Kenyan-owned company, it enhances the standard of living of the small scale tea growers of Kenya who are the bulk of its shareholders.
Kenya is one of the world’s top 20 coffee producers and has a good reputation for its Arabica beans. Kenya produces 2 million bags of coffee a year and the coffee industry employs 6 million people (www.coffeeboardkenya.org) .
When it comes to exporting flowers (http://www.kenyan-flowers.com) , Kenya is a global powerhouse: 38 percent of the world’s exported flowers are grown there. The majority – 97 percent – are sent to the European Union. Its popular flowers include chrysanthemums, roses and carnations. This time-sensitive crop benefits from the air links of its capital, Nairobi.
Kenya even has a successful brand of beer, Tusker Lager (http://www.tuskerlager.co.uk) . It is a leading export and is proudly African, with its elephant logo and motto “My beer, my country.” It has a large market in the United Kingdom.

Using the Internet in Africa has its challenges, as anyone who has worked there knows. Issues can include weak Wi-Fi signals, slow Internet service providers, electricity outages and power surges that can damage or destroy sensitive electronic devices.
Power surges (http://electronics.howstuffworks.com/everyday-tech/surge-protector3.htm) can occur for a variety of reasons but are usually a sudden surge in the current flowing to the wall outlet from the power mains. They are common in developing countries, and can be tragic for electronic devices.
Most electronic devices are designed for use in developed countries where people can take the power supply, and ubiquitous Internet access, for granted. This affects the way devices are made. Designers will assume many things are available to users and build the electronic devices accordingly. But for users in Africa and across the global South, what seems easy in the developed world is fraught with frustration and wasted time.
This is a big obstacle to economic development and places people in Africa at a disadvantage in the modern world of fast communications.
One initiative is out to transform this experience for the better with a made-in-Africa solution that is being modified based on real-world experience and user feedback.
The BRCK (brck.com) bills itself as “your backup generator for the Internet” and is intended to address the problems of finding a reliable Internet connection, staying online in a power blackout and saving devices from destruction when there is a power surge.
Anyone who has tried to use a laptop computer to upload some photographs in Africa will know the frustration felt when the Wi-Fi signal drops away. The BRCK hunts around for the strongest signal and grabs it so the user can carry on working.
Built to be robust and take knocks and bruises, it is a sleek, black plastic brick-shaped device with the letters BRCK elegantly embossed on the side.
The BRCK can function as a hub for up to 20 devices, with a built-in Wi-Fi signal able to cover multiple rooms (so a team can work off a single Internet connection), a battery that can last eight hours, a 16-gigabyte on board memory hard drive, and software to allow for remote management by apps on other devices such as smartphones. While it is not able to speed up an already poor connection or increase low bandwidth, it can “scavenge” around to find the strongest signal and hop to it right away. It can work with Ethernet, Wi-Fi, and 3G and 4G networks.
If a blackout occurs, it quickly switches to the onboard battery without forcing a re-boot of the computer.
It has been developed in Nairobi, Kenya and the first plastic prototype of the BRCK device was milled at the Fab Lab Nairobi (http://fablab.uonbi.or.ke/) using a 3D fabricator machine.
The BRCK’s makers describe it as a tool “trying to create ubiquitous Internet” and an “enabler of the Internet of things.” The BRCK is designed around the changing way people work and access the Internet, frequently moving from place to place. People now don’t just rely on one device but have many – a mobile phone or smartphone, a laptop, a tablet, an iPod or other device.
A Kickstarter fundraising campaign (https://www.kickstarter.com/projects/1776324009/brck-your-backup-generator-for-the-internet) gives more details on the origins of the project and offers many ways to support the different stages of development, right up to mass manufacturing of the BRCK.
One application of the BRCK is for research. It could be deployed to gather data at a field site, then connect via the Cloud (http://en.wikipedia.org/wiki/Cloud_computing) to pass data back to a lab at a university in another country for analysis.
The BRCK is being built by Ushahidi (ushahidi.com), a non-profit technology company that makes open source software and made its name with the crowdsourced mapping platform it built during the post-election violence in Kenya in 2008. The Ushahidi platform has been deployed around the world since in many crisis situations.
Founded by David Kobia, Juliana Rotich and Erik Hersman, the Ushahidi team is focused on “building tools that improve the way information flows in the world.” It is about making tools to help people communicate in the most difficult places.
BRCK comes with a visually appealing website that makes excellent use of the BRCK’s ebony good looks.
The website boasts: “If it works in Africa, it’ll work anywhere”.
The ongoing development of the BRCK can be followed on the website’s blog: http://www.brck.com/2014/01/they-case-for-engineering-brck-in-africa-part-1/.
“The idea is to build a company around the product rather than just do a one-off product – and to gradually improve the product through new versions,” said BRCKs chief technology officer Reg Orton.
“Our engineers are based in Kenya now – we are not based in China, we are not based in the (Silicon) Valley. What that means for us we are able to go out there and (be) able to see the problems directly.”
The BRCK can be ordered online and will be available for sale soon, according to the website.
