We are not really sure if this homemade aircraft will ever manage to take off (or land), but – according to the following reports aired on Kenyan TV a few days ago – I.T. specialist Gabriel Nderitu from Kahawa West in Kenya obviously spent much love & funds on building his very own aircraft.
Our avid readers will certainly remember Mubarak Abdullahi’s home-made helicopter in Nigeria, the homemade helicopter in Somaliland as well as this odd story on someone who claims to having built a single seater aircraft way back in the 1970s from an old VW Beetle engine (hey, at least air-cooled, the way it’s supposed to be). The important and innovative part, it seems, is that these guys were willing and able to invest time and money into their projects – even though success is uncertain.
The Kenyan TV station did a follow-up on the story and… well, it seems that Mr. Nderitu miscalculated the stability of his landing gear (among other things).
The balloon shows that gas is being produced. The costs for the drum and professional valves may already be too high for some, and the design isn’t that optimal. They intend to add a storage drum with a water-filled header tank for constant pressure and the loading & desludging processes obviously still require some work.
We still like the approach though, because it does indeed “prove the theory”, as David notes. The theory of building a rather small anaerobic digester that will even work with smaller amounts of organic waste.
Goes to show that producing methane gas from something which would otherwise remain unused (livestock faeces usually kept in such drums for a few weeks without harvesting the methane potential) still is an interesting alternative & well appreciated once costs are covered.
Our friend Bill Zimmerman, a technologist who runs a startup un-incubator called LimbeLabs in Cameroon, posted this interesting story on his blog about a teacher who makes an extra income by fabricating gadgets out of Bamboo.
Avid readers may remember the Bamboo Bike project, so the idea of using Bamboo as an alternative and sustainable material isn’t that far fetched. In fact, we’re glad that someone took the initiative and ventured into this field with so many different products at the same time. Bamboo Magic, really. Make sure not to miss out the video!
“I had an opportunity to stop by the 2009 South West Regional Agro-Pastoral Show, an annual exhibition for local farmers and craftsmen, here in Limbe this afternoon. The event was held on a community field ringed by exhibition booths overflowing with every imaginable vegetable, fruit and live animal cultivated and raised in the southwest region of Cameroon. In addition, there were a number of innovators with homemade products and gadgets crafted from local materials.
Amid all the displays, one guy stood apart with some creations that can only be described as a near perfect marriage of form, function, green design and a borderline obsession with bamboo. Lekuama Ketuafor is the proprietor of Bamboo Magic, a one-man cottage industry he’s started to supplement his work as a teacher.
Using a set of simple hand tools, glue, varnish, skill and loads of patience, Lekuama finds ways of using bamboo—a ubiquitous, low-cost, renewable material—in ways many people have never imagined. Judging from the size of the crowd gathered around his booth, I suspect few Cameroonians had seen anything quite like Lekuama’s creations before.
Among the intricately decorated bamboo shoes [2], vest, palm wine calabash, cowboy hat, clocks and so on, I was immediately attracted to two incredibly cool electronics-related pieces: a bamboo covered Nokia phone and an attractive and functional laptop case. Here’s a video of Lekuama, dressed appropriately in head-to-toe bamboo wear, demonstrating these items:
The attention to detail on the laptop case is impressive, right down to the external USB port access, shoulder strap attachments, carry handle, magnetic clasps, internal elastic keeper strap and red felt lining. And how about that chic mobile phone?
Due to the time intensive nature of his craft, Lekuama makes these items for sale in very small quantities. However, his dream is to establish a training center where he can transfer his skills to young Cameroonians and build a community of artisan microentrepreneurs.”
Obviously, agricultural shows in Africa are a great resource for AfriGadgets.
After all these fascinating AfriGadgets from Maker Faire Africa, here’s another invention as seen by our friend Cedric Kalonji, a Congolese journalist in Kinshasa (D.R.C.):
For the lack of a cheap power supply in the City of Kinshasa, smart mechanics came up with this little stove that speeds up combustion by adding a little electric fan (hidden inside this tube that looks like being part of a flat spring). The fan itself is powered by (Chinese!) batteries and with the burning of charcoal, this quick stove obviously isn’t the greenest solution. But it works and does the job for those who will otherwise have no alternative.
Cedric also mentions on his blog post that it’s difficult to identify the inventor of this device. A perfect example of how low-cost technology easily gets adopted and/or modified (and why intellectual property rights are still a major issue in many places).
