What Do You See?

I have a talk that I give when people ask me to speak on AfriGadget at conferences that is called, “What do you see?”. It’s a visual and interactive quiz where I take the audience through different images of AfriGadget and ask them what they’re looking at. It’s a lot of fun, and it proves to everyone why it’s so hard for people in the West to come up with contextually relevant life hacks in Africa.

Below are some images from an old family friend who has spent his life working in rural Southern Sudan and Kenya. Under each image you’ll see why it’s interesting. By the way, I too missed the relevance of the flip flops at first glance…

Making use of available resources for a hinge. I really like the way that Ben has used these old slippers and shoe for the hinge of his small kiosk/shop at Butere.


Home made African chair

This old chair at Mahanga in Western Province shows the ingenuity of the local carpenters in making use of available resources, with the carton and stuffing from sisal and wood shavings.


Bottles and plants in Kenya

I saw one just like this in Bungoma, but was not quick enough with the camera to get a good shot. Turns out Zain, a major mobile phone service operator is using these as pre-fab offices in rural areas.

Turkana zipper head dresses

While visiting a rural community in the dry bushlands of Elementata I met some Turkana women who were absolutely captivating

Did you notice the creative head dresses? Zippers may have been invented in USA but nobody would have imagined they’d be used for head dresses.  I was so awed by the outfits that I forgot to ask where they got all those zippers from - I can’t get rid of the image of all the village men wondering about with gaping flies.

Toy Tractor from Recycled Plastic

Taken in the Rift Valley province of Kenya, this picture shows two young boys with their toy tractor. Notice the use of discarded plastic and a few nails. Simply ingenious, simply Afrigadget!

Paraffin Lamps and the Informal Recycling Industry

Franco Mithika works in Gikomba, an industrial area in greater Nairobi. His job is to take scrap metal tin cans and a soldering iron to fabricate paraffin lamps. Paraffin lamps are used by millions of Kenyans, especially those who cannot afford or get electricity into their home for lighting.

Creating Paraffin Lamps in Gikomba

It costs about 110/= Kenyan shillings to make, and it sells for around 150/= ($1.90). You can buy them wholesale for 1550/= ($20) for 24 pieces. It takes about a minute to make one (less for the truly gifted fabricators).

Here is a video of him making one:



Thinking about the unofficial recycling industry

What’s particularly interesting here, is that this scrapes the surface of a rather larger recycling industry that hums beneath the surface of the city. How it works is this. The youngest and poorest go around the city and collect scrap metal of all types. These are then taken to a buyer who sorts them into their different types. This is who people like Franco then buy from and create their wares.

The scrap metal picked up gets sold for just a few shillings per kilo. When sorted, the tin cans that Franco buys, are sold for 300/= ($4) per kilo.

So, there’s a rather efficient system at work. It’s run by entrepreneurs who figure out a way to make things work. A byproduct is that everything (metal) is used, and much less waste than there would be otherwise.

The Swahili Bed

A Swahili bed and couch

The Swahili bed was in a recent article on MAKE Magazine (a publication that inspired AfriGadget’s creation). In it they discuss why this style of bed is so useful on the hot and humid East African coast.

“In Kenya, the most common and most useful piece of furniture is the rot- and bedbug-resistant Swahili bed.”

“In most houses, you can only find one type of furniture: the Swahili bed. It’s used as a couch, bed, table, and everything else. It’s comfortable and perfect for the hot, humid climate.”

The beds are made from locally grown mvuli or mbamba kofi trees, then straps are created out of palmetto leaves which are soaked in salt water and woven into rope.

Years ago I used to export furniture like this from East Africa, so it’s something that I happen to know quite a bit about. Which provides yet another lesson for those of us who live, or work, in Africa. That is, items that seem mundane to us, as we live our lives in Africa, can be quite exceptional if we only stop to really look.

Philip’s Model Plane at International ArtBots Show (Video)

“I feel good when I do these things.”

One of my favorite stories on AfriGadget has been of Philip Isohe and his hobby of making very detailed (and working) model airplanes and buses made from scratch. Earlier this year, the ArtBots Show contacted me to get Philip to create one for them that they could show at their annual show in Dublin, Ireland that is happening this weekend. The airplane will be given away as a prize at the show.

They also asked me to create a video of Philip to use at the show:

Building The Sun - A Kenyan Videographer’s DIY project

Jim is a musician, videographer and member of the Kenyan animation trio Just-A-Band. He needed a consistent light source for his video shoots, and as he puts it…
1. the sun is REALLY powerful
2. but very unpredictable

So he decided to create his own lighting equipment from easily available components that included:

1. 2 cardboard boxes (20/-)
2. 15 bulb holders (approx. 150/- each)
3. energy saving bulbs (the 23-watt ‘cool daylight’ types - 450/- each. Ouch.)
4. a roll of aluminium foil (approx. 200/-)
5. lots of cellotape/masking tape

With the help of his friend Kevin who is an electrician, he went from this

and

To

Contrast his total cost of approximately 7000 Kenya shillings (about $113) with Tungsten lights being sold in Nairobi, Kenya for 20,000 Ksh (about $320), this is a neat DIY project that not only saved him some money, but also shows the African Ingenuity we are always excited about.

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.
