One Man, an Airplane and a Hummer

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.

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!

Africa’s Modular Machines

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.

Mubarak Abdullahi’s home-made helicopter takes Nigeria’s Kano Plains by storm

Yahoo! News (among other sources) carries a story from October 21st about Mubarak Muhammad Abdullahi of the Kano Plains of Nigeria who has built a working helicopter over the last 8 months using scrap aluminum and parts from a Honda Civic, an old Toyota and from the remains of a crashed Boeing 747.

This inventor has had no formal training in flying and his helicopter has never flown higher than 7 feet of the ground. In an interview, he talks about how the machine works:

“You start it, allow it to run for a minute or two and you then shift the accelerator forward and the propeller on top begins to spin. The further you shift the accelerator the faster it goes and once you reach 300 rmp you press the joystick and it takes off,”

Mubarak is ambitious however and has embarked on a new project to build a better helicopter that will be able to make 3 hour flights. He hopes to get support for his project from the Nigeria Civil Aviation Authority (NCAA) and other Nigerian government bodies.

Where the World Sees Junk, Africa Recycles

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.

A Successful Business Entrepreneur in Africa

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.

HAPV – Human and Animal Powered Vehicle in South Africa

The HAPV (Advertised as HAPPY) is a twist on the ‘horse and buggy’ mode of transportation, making this a donkey, cart, solar panel on a canopy FUV (Farm Utility Vehicle) that is quite ingenious and absolutely AfriGadget. A donkey drawn carriage is commonplace in many countries in Africa, and this retrofit by the organization Water and Wheel adds more functionality and utility especially suited for rural Africa.

Fitted with a solar panel that charges a 12 volt battery under the driver’s seat, the “HAPPY” becomes an independent, sustainable source of energy that powers cell phone connectivity, front and rear emergency lights and a small neon tube at night. Add a water filtration system, and the “HAPPY” doubles as a multi functional mobile business unit, that can empower an entrepreneurial owner, to generate income from it as a fresh water outlet, a mobile phone kiosk or a spaza shop – even after dark.
