AfriGadget Innovator Series: Simon Mwacharo of Craftskills

I recently had a chance to conduct an email interview with Simon Mwacharo, an entrepreneur based in Nairobi, Kenya who a great example of what George Ayitteh has so aptly described as “The Cheetah Generation”.

Simon owns and runs CraftSkills, a small business based in Nairobi, Kenya that focuses on designing and building self-sustaining renewable energy projects in places not accessible to the electric grid. Craftskills had to date undertaken challenging projects in Kenya, Uganda, Tanzania, Cameroon and Rwanda among other places. Simon, whom AfriGadget first got to meet last summer at TED Global in Arusha, Tanzania, graciously agreed to conduct an email interview with AfriGadget.

Craftskills windmill project

AfriGadget: Could you tell us when and how Craft Skills got into the business of renewable energy in East Africa and the inspiration behind the organization?

Simon: CRAFTSKILLS was found in the year 2000 by myself. I was inspired by a challenge from my rural home where we have not had power for the last 40 plus years since [Kenya’s] independence [in 1963]. I come from a hill side village in Sagalla, Taita Hills in Coast Province where we receive quite some strong wind from the Nyika Plateau. This wind passes through without being tapped and sometimes our roofs can not stand in its way.

I started talking to people about wind turbines and how I can get an affordable one which I can make and produce for other needy people. When darkness falls in these villages plus the fog it is virtually impossible to travel the terrain at night.

AfriGadget: Tell us a little about the people behind Craft Skills and the staff who work for the organization.

Simon: I started with two workers. I could not afford to hire trained people so I decided to train myself first then train my two boys. Then I got a friend who repairs radios and TVs in Kibera to help me design and put together a charge controller.

Now we have a team of 20 people and other partners out there in the field with their staff totaling 50. We have technicians, welders fitters, fiberglass experts and engineers and sales people.

AfriGadget: What is the typical profile of a Craft Skills project? Who is your typical client and how are the projects typically executed?

Simon: Most of our clients are not the owners of the projects we put up. They benefit from the battery charging services in the wind/solar sites we put up with our partners. The low income earners who cannot afford grid power or are in settlements where grid power is unavailable. We take both to do the sites ourselves involving the people on the ground as partners. Others are home owners who have invested a lot on building good homes in non grid areas – these put up turbines for their own use like lighting, and pumping water from wells and boreholes. The other segment is the business people I market areas where there is no grid who put up turbines to run charging centres and sell power to other shops or run their off-grid businesses like lodges and hotels, schools and other institutions.

AfriGadget: Can you share with our readers some of the challenges that Craft Skills faces in executing your projects?

Simon: We have faced cultural challenges where we cannot put a turbine on the most ideal site due to beliefs on such sites hence we have to educate the citizens to allow us to do so or redesign the project and relocate. Another is the financial capability of the citizens we find in these off grid areas.

[As a result of this] we have designed low power product (battery bundles and LED lights) to reach them so that they can be counted as beneficiaries of this new technology.

AfriGadget: Why renewable energy? What is the rationale behind Craft Skills’ exclusive focus on projects that produce energy from renewable sources.

Simon: We were looking for something which is affordable and sustainable and cuts across the economic sectors. Solar was proving to be more expensive, delicate, sophisticated and easily stolen when installed on ones home. We needed to sell people more power at a cheaper rate hence wind was the best candidate.

Wind is everywhere just like solar – one needs to get the right spot to put the turbine as high as they can. Its 24 hrs (Day and Night) and we found a cheap way we could make our turbines take advantage of low wind situations with the multi-pole generator, hollow blades for the propeller, with 90 per cent locally available materials making our technology the best application for this region.

AfriGadget: Which would you say has been the most satisfying/gratifying project that you have been involved with at Craft Skills? What was so special to you about this particular project?

Simon: The Chifiri water pan project to me is most gratifying. This settlement is all arid land pastoral community. The demand for water for drinking washing and watering the thousands of livestock is enormous.

Our turbine provided a cheaper solution for water and lighting the “manyattas” around the water pan. The contractor on the ground is excellent on his construction of the earth dams. His design impressed me that water was going to be available for over 6 months instead of the normal 4 months after the rainy seasons. He made sure the dams were well compacted and fenced to avoid animals hoofing inside the dam – increasing the rate of percolation and lose of water in the ground. Water is only available at the kiosks which are piped and placed near the settlements. The project provides water troughs for the animals to drink from and bathrooms for the people to clean themselves in. Within the fenced dam there is an armed home guard or caretaker manning the place with a security light up the tower hoisting the turbine.

Bio-Diesel From a Small Village in Sierra Leone

Makeni is a small town in Sierra Leone. Like the rest of the country, it is trying to recover from years of internal strife. Unlike the rest of the country, they have the Binkolo Growth Centre, a small industrial project near Makeni where the manufacture of small farm implements, tailoring, carpentry and blacksmithing takes place, and includes the use of disabled people. Two VSO volunteers, one from Kenya one from Canada, work to train and bring new ideas to the centre.

One such idea was to create a fuel replacement for their pickup by using local palm nuts, a by-product of the palm kernels, which are generally fed to pigs or used for fertilizer. Since diesel fuel for their truck runs approximately $5/gallon, it wouldn’t hurt to try.

Palm Nut Crushing Machine

It became clear that in our poor country the chief hurdles were getting the chemicals and the right equipment. The search was on for the chemicals and after quite a treasure hunt and more than a few bribes we managed to find 4 litres of Methanol and 5 kilos of Potassium Hydroxide (enough to make a good bomb I think)…

…Actually the whole scene was quite amusing. Here we were hoping to compete with the big oil producers in the back yard of a small village and using an untried collection of old car parts, old pipes and taps attached to a used chemical container, all put together in an image downloaded from the internet. Nonetheless we were fuelled by much excitement, with much of the local community looking on, wondering what on earth we were up to.

Mobile Phone Ingenuity in Africa

This last week I had the opportunity to catch up with one of my favorite bloggers, Jan Chipchase, while we spoke together on a panel at the Global Philanthropy Forum. Jan works for Nokia as what can best be described as a design and usability ethnographer. He explores the way mobile phones are used worldwide and reports that back to Nokia’s design team. He’s a fascinating person to talk to, and I thought I might highlight some of the stories he’s come up with while exploring in Africa.

Creating a new mobile phone from old phone partsOne of the consistent themes of Jan’s message is that it in each country he visits there is a booming market of hackers and mobile phone mechanics who are doing all kinds of interesting things. They are taking the designs of the West and applying them to their lives, modifying them and making them work for their local needs. From Accra to Nairobi, there is always a “cell phone alley” for you to buy, repair or customize your mobile phone.

In a post titled, “Recycled, Upcycled: Remade” he tackles the question of whether it is possible to create a phone completely of recycled parts.

Of all the internal concepts I’ve followed this year this is one I keep returning to, not least because sustainability is a pressing issue in a billion+ products-per-year industry - but also because the team tackled a number of related weighty issues in what was a far reaching project. I hope that in due course more of their design thinking makes it into the public domain, not least to stimulate critical feedback from people like your good selves.


Dual SIM card in Accra, Ghana

One of the more interesting innovations is the development of a dual SIM card hack so that users can access multiple carriers.

This product has two SIM card slots in a single phone - primarily to support price sensitive/prudent consumers who wish to optimise their call costs by maintaining SIM cards from two different phone operators. As in many countries - calls to a customer using a different Ghanaian operator cost slightly more than those on the same network.

There are many more examples of mobile phone use in Africa and the ingenious solutions that locals come up with for their particular situations on Jan’s blog. The last image that I want to show is of the Village Phone project (by Grameen Bank) happening in Uganda. Jan has taken an excellent picture and annotated it with the important facts about this project in a rural Uganda.

Fighting Hunger, One Village at a Time

The Universal Nut Sheller (UNS) is part of the Full Belly Project. It’s really an amazing story about a device that has had a direct impact on a number of African countries. The story goes that Jock Brandis, an American inventor, was on a trip to Mali and saw some women who had been shelling peanuts leaving them with bleeding hands. This spurred him on to create a device that would help end hunger.


The Universal Nut Sheller in Africa
(Watch a video of a pedal-powered one in action)

How does it work?

The process works by centrifugal force and friction. The Universal Nut Sheller is basically a concrete cone within a cone, open at the top and bottom, with the interior cone being solid. The interior cone, or rotor, rotates on a shaft and has an attached handle (Note: only one moving part!). The user turns the handle around fast enough to spin the nuts to the outside through centrifugal force. The nuts fall between the surfaces and are rolled and squeezed, allowing the nuts and shells to fall through to the bottom. This mix of nuts and shells is then winnowed out, the old fashioned way.

Reach and Impact
According to the Full Belly Project, this machine is being used in 12 African nations, including; Mali, Uganda, Malawi, DRC, Gambia, Ghana, Kenya, Nigeria, Senegal, Sierra Leon, Sudan and Zambia.

The nut sheller is being used to shell more than just peanuts. As new villages take up the device, they turn it towards their own diverse nut shelling needs, such as jatropha, neem nuts, shea nuts or coffee.

Most importantly, he Universal Nut Sheller costs about $50-75 dollars to make, depending on the price of local materials, and will serve the needs of a village of 200 to 1000 people.

Like two past projects that we’ve highlighted on AfriGadget, this one is encouraging. Both the recently profiled see-saw power machine (possibly), and the KickStart pumps are based on the belief that sustainable economic growth comes through empowering local entrepreneurs to start, or extend, their businesses. In fact, the plans for the UNS are free and downloadable.

Powering African Schools with Playground Toys

Dan Sheridan and his see-saw power idea for African schoolsThe BBC is running a story on a young inventor, 23-year old Daniel Sheridan, who has designed a teeter-totter (see-saw) that can be used to power school classrooms in Africa. His ultimate goal is to see a whole playground of energy-creating equipment.

“The current need for electricity in sub-Saharan Africa is staggering. Without power development is extremely difficult. The potential for this product is huge and the design could be of benefit to numerous communities in Africa and beyond.”

The idea came about after travels to East Africa, where he taught at a school and was inspired by the students. Daniel developed the see-saw power design as part of his final year at Coventry University. He has calculated that five to 10 minutes use on the see-saw could generate enough electricity to light a classroom for an evening.

Some Thoughts
What would be more interesting would be to see this idea built out with local supplies, as Daniel is going to be doing soon in Uganda. Then, with the knowledge learned there, see if it could fall into the same model of micro-entrepreneurial devices that we see with the KickStart water pumps. Speaking of which, this also reminds me of the PlayPumps idea, which also has a lot of potential.

Daniel states, “The unique selling point of this product is that it is not intended as a profit-making design.” I can only hope that he means this as profit for him. Profit making on the ground by Africans of this type of design could be crucial for its long-term success.

AfriGadget on the BBC/PRI “The World”

AfriGadget’s second monthly BBC/PRI interview with The World is now live. Juliana, one of the editors who also blogs at Afromusing, was interviewed this month. You’ll hear her start talking at about 17:15 in the podcast.

Affordable solar charger for Mobile Phones

Our friend Ken Banks of Kiwanja.net and NGOMobile wrote about the challenge of mobile phone charging in off grid Africa; noting that this solar powered charger could be one of the solutions. 75802145-B69F-4065-A5DC-C40CA6D90D4B.jpg

I quite agree; two years ago i bought a similar solar powered charger that cost $99. The charger pictured above is made by G24 innovations, and costs $20. This is just the kind of technology that AfriGadget likes, because it is not only quite handy to have, but it is empowering and well suited for off-grid rural areas in Africa,  California or anywhere with sunlight for that matter. Ken explains it best…

In some rural areas, where the lack of reliable mains power might be the difference between making it worth owning a mobile or not, a small solar panel such as this could be a deal clincher. Of course, solar energy has been touted as a solution for charging mobile devices for years now, but what’s interesting about this is the cost. Suddenly, it actually seems possible. And by possible, what I really mean is affordable.

Read more about the device.

AfriGadget: the story behind the stories.

What does it take, out there in the field, to get an AfriGadget story?

Well, this video that I took back in the summer of 2007 shows Hash (aka WhiteAfrican) hard at work getting the Africa’s Modular Machines piece that went up in AfriGadget last November. Yes, the sound quality and camera work are atrocious but sometimes, opportunity just presents itself.

I am happy to report that as you can see, he was busy bringing Firefox to the people as he did this.

Simpsons Carvings from Kenya

This one is not exactly AfriGadget, more like an AfriToy, but we love the story nonetheless. The video reporter Ruud Elmendorp visited the small village of Tabaaka, near Kakamega, in western province Kenya. Below is a video showing the master carvers at work, creating soapstone figures of The Simpsons characters. The carvings are available for online purchase through the CraftVillage website. Please click on the image below to view the video.

Al-Jazeera also covered the story last year, focusing on the economic boost of the Simpsons movie on the village, as it saw an increase in the number of orders for the carvings. It is the confluence of popular culture and African handicraft that we particularly enjoyed when it came to this story. If we had our way we would have soapstone carvings of Strongbad! One day.

PS: AfriGadget will have a monthly feature on The World Technology Podcast, which you can subscribe to here. The first issue is now posted. Many thanks to Clark Boyd, the AfriGadget team is quite excited about this.
