Over the weeks since the first post we did on Dr. Cedrick Ngalande’s inexpensive power source for Africa, we’ve been emailing back and forth about his invention. Yesterday, he sent me a link to a video of his device on YouTube.
“The rotor moves slowly most of the times but does pick up at certain intervals. This process continues for many hours. Since the rotor is quite heavy (and hence more inertia) a small geared DC motor can be connected to the rotor to generate power for cell phones, $100 laptops, and other things in Africa. People can leave this thing to charge their phones/$100 laptops overnight.”

We’ve written about young Malawian William Kamkwamba a couple of times here on AfriGadget, so it’s great to see him getting recognition in the WSJ! The article is titled “A Young Tinkerer Builds a Windmill, Electrifying a Nation“. Take a look at the video:

Victor Kaonga points us to Dr. Cedrick Ngalande, a Malawian, who has built a prototype power source made specifically for Africa. It generates power using sugar and yeast for up to 8 hours at a time.
Mobile phones are big in Africa, however it’s a real challenge to power them. How about night time electrical lighting, rather than paraffin lamps. Of course, in Africa we can think of all types of applications that this device could be used for.
This gadget will be very ideal to developing countries like Africa where electricity is scarce. As you know, the growth of cell phone is fastest in Africa. The problem most Africans have is that they cannot charge those cell phones due to lack of electricity. Some have to walk long distances just to charge cell phones. My invention will make it easy for these people to charge their cell phones. Also, this generator can be used to charge $100 computers which are being introduced in Africa. It can also be used to charge or operate medical devices in rural Africa.
On a side note, I love seeing inventions made by Africans for Africans. It’s only by living and being a part of the everyday life that you get past the surface issues and start to really understand the real problems to be overcome. Personally, I love this story; it’s ingenious and African - just what we like here on AfriGadget!
If you have any stories, pictures or videos of ingenious African solutions, send them to us!

There’s a really interesting story about a man in Kenya who claims to have created a plane from scratch.
Using a Volkswagen beetle engine, and aluminium sheets for the body, Mr Gachamba made a single seater plane.
He tested it out at an airstrip in Nyeri and sure enough, it took off. Caught up in the excitement of the minute, he decided to fly to his home in Mathira.
A few minutes into the ride, he noticed the engine was overheating. He decided to turn and in the process the low flying plane struck a tree top and crash landed. He was injured in the leg and has had a limp since.
(Read the rest of the article)
I’d love to see pictures of this plane, though I’m doubtful of there being any as this happened in the 70’s. Either way, a fun story. Right now he’s building his own Hummer from an old Datsun engine and “wheelbarrows, wheelchairs, metal pipes and other vehicle accessories”. At 75 years old he’s not slowing down at all!

One of the things that I find most interesting in my travels around Africa is the similar uses of technology to meet the varied demands of different types of mechanics and workers. The particular case I’ve been thinking over is the use of a simple frame and different engines to meet a specific need.
Many of the same components are used from one machine to the next. The fabricators know that each machine has a different use, but that the parts used to make them unique are not that many.
For instance, below is an image of a painting machine.
The painting machine has an engine, an air compressor and a tank for holding the compressed air.
I’ve seen the same setup, switching out the air compressor for a circular saw, water pump, or a generator. In the same way, the compressed air tank can be switched out for a larger fuel-holding tank or some other machinery that fits the specific need.
Below is an image of the same type of machine, this one with the same setup, except that the compressor is used for tire repair instead of painting.
Generally, the engine and the frame are the mainstay. The engines used are primarily Briggs & Stratton, the old workhorses of Africa, though I’ve seen Honda trying to make headway in this market lately as well.
The machinery setup is a good example of low-cost fabrication using a modular setup. All of the local fabricators tend to use the same frame setup so that they can mix and match with each others work.

[Update: I'm currently going through my archive of pictures and videos for more machines like this. If you have some pictures of these types of machines, please send them my way.]

This post is dedicated to Blog Action Day, where thousands of blogs around the world unite to talk about one theme. This year it is the environment.
Simon Mwangi calls himself a mabati (sheet metal) blacksmith. He takes junk and creates beautiful metal animal sculptures. If you happen by his roadside shop on Ngong Road in Nairobi, you’ll see a number of crocodiles and if you’re lucky, a full sized giraffe.
If you’re in the market for a crocodile, which he sells primarily to hotels, be ready to pay 30,000 Kenya Shillings (about $450). They take about one week to make.
What’s remarkable about Simon, beyond the actual artwork that he fabricates, is that everything he does and works with is made from left over metal junk. Even the welding machines that his team uses are made by the team from leftover metal plates and copper wire. (See an example of the welder at this earlier AfriGadget post)
This is an excellent example of how Africans reuse and recycle to meet their needs. Many times their ingenuity creates thriving businesses, proving that entrepreneurship and environmental needs aren’t mutually exclusive.

Most of the stories on AfriGadget are stories of work-based ingenuity. However, every once in a while you get an incredible story about someone who creates an amazing do-it-yourself “fun” item. In this case Wired is reporting about Cyril Mazibuko who creates his own home made paraglider:
Cyril is the only black South African currently registered with the sport’s ruling body. And it all started with a glider he made from plastic bags, purloined rope and baling wire, a glider that flew — sort of — though it both amazed and horrified the professional paragliders who saw it.

Ken Banks of Kiwanja.net is a mobile expert as it relates to the developing countries. He sends in a picture from his most recent trip to Uganda. 200 Ugandan Shillings per unit is equivalent to about $0.11.
Ken on the BodaPhone:
I met this phone operator off Kampala Road this afternoon, who was riding round on this bike. Luckily he was a fellow Liverpool supporter so we hit it off straight away – and he let me take a photo of his BodaPhone setup. Pretty neat, and with a spare battery to allow him to stay on the road longer. Uganda is really hotting up on the mobile front, with two new operators about to enter the market towards the end of the year.

Ken is quite active in this space and runs the very popular Social Mobile Group, found on both Facebook and on his site. He has also been interviewed in a story today on BBC that talks about the mobiles in Africa.

Simon Kasiraba is one of many sausage vendors found in the cities and small towns throughout East Africa. He’s the prototypical micro-entrepreneur trying to make a living by supplying a need (food - conveniently available). He’s on AfriGadget because of the simple innovative solution that he employs to keep his food ready to be eaten at all times of the day - which is very important when you’re set up beside a bus stop.

He keeps the meat warm using steam, with a simple charcoal heater placed inside the body of the sausage cart. The water goes into the pipe on the side of the cart, and floods a water panel directly underneath the meat. When it gets hot, the steam keeps the sausages warm, yet juicy. The cart cost him 14,000 shillings (about $200). He sells each sausage for 10 shillings (about 0.14 cents).
Here is a video of Simon showing me his sausage heating cart:
Images of the sausage heating carts can be found in the AfriGadget Flickr image pool.

First off, I’d like to thank the thousands of readers who visit AfriGadget every week. It’s been great to see the amount of interest that innovation Africa-style engenders. I’d like to give a little update on what’s been happening and where we’re going with AfriGadget in the near future. If you’d like to help in some way, please contact me.
Some AfriGadget Groups
AfriGadget Flickr Group - We have an image gallery on Flickr that you can take part in. Tag your images “AfriGadget” and add them to the AfriGadget group.
AfriGadget Facebook Group - Just started this month, the AfriGadget Facebook group is a place that you can talk to other AfriGadget readers and find like-minded friends.
Website Redesign
This has been a long time coming. The current site has some problems that we’d like to “fix” via a redesign. We’ll still be using WordPress, but want to make it more accessible and increase the breadth of information available. Feedback indicates that people like the look and feel of the current site, so we’ll try and stay pretty true to what you see now.
There has been an ever increasing number of emails asking for more information on specific projects, as well as a great deal of interest from people who want to purchase some of the items that we’ve shown on AfriGadget. We’re going to be building in some of those features into the new site.
Helping Micro-Entrepreneurs
I’ve had a number of interviews by different media outlets over the last couple months, and one specific interview by a South African radio company really hit me. They asked, “How does AfriGadget help the Africans who are beings showcased?”. I didn’t have an answer - or, I did, but the answer was “not at all”.
In the new site, we would like to work with an organization like Kiva, and their partners, to create ways for people to invest in some of the entrepreneurs that we talk about. In the cases where it makes sense, we’ll also help the entrepreneurs sell some of their items via our website.
Growing AfriGadget
The website initiative is only one of the three that we’re planning for this year. If we can find the right partners, we’ll be announcing some projects that a couple AfriGadget editors will be leading that are, quite frankly, much more exciting and “big” than a website redesign. As we grow AfriGadget we’re looking for partners who can help us. Contact me if you’d like to know more about those initiatives!
All of us do AfriGadget on the side. The growth of the site that I have outlined above is meant to benefit the innovators in Africa, not those of us who manage and create content for this site.
