Dr. Ngalande’s Sugar and Yeast Power Generator

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.”

Africa’s Modular machines Continued: Saws

This is a continuation of Erik’s post on African Modular machines.

The video below shows how the machines are used in wood workshops to make design cutouts, carve out pieces for furniture and to split planks of wood. It is essentially the same machine pieces, motor, pulleys and frame, just customized for different uses. The customization is done in a small industry locally known as Jua Kali or Gikomba, where entrepreneurs like Mr. John Chege purchase them for use in small workshops like this.

When playing the video, please mute it, there is lots of noise from the machines.

William Kamkwamba in the Wall Street Journal

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:

Malawian Invents a Power Source Made for Africa

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.

Electric power by sugar and yeast

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!
