Catwalk ready arc welder

This bizarre fabricated arc welding machine is the unique collaboration between jua kali and mitumba. Jua kali literally means hot sun in Kiswahili, and refers to the informal small traders who work outdoors in the sun fabricating mostly work metal and wood items, fixing cars and other household items. Unable to afford new tools they fabricate their own out of locally available materials. Mitumba refers to the second hand western clothing sold on the streets of many African cities. The arc welder uses stolen scrap and second hand wires that are coated for insulation using strips of cloth torn from unsellable mitumba clothes.  This is then wound into the welding machine coils.

God help James if it rains!

I’d gone to Limuru to get a welder for a job on a dairy where I met James Mutahi. He is a typical jua kali wrought iron artisan who operates on the sidewalk outside his street workshop using his own home made tools.  I’ve seen jua kali home made arc welding machines before but usually they are housed in a protective box. To save money James dispensed with the casing revealing the guts of his arc welder.

James was making security grill for a window. There’s a huge demand for arc welding in Limuru especially for gates and window bars which are essential in the high risk security zones of Nairobi and other urban centers.  Nairobi’s security is the result of the collaboration between mitumba and jua kali!

The picture speaks volumes about the Jua-Kali sector in Kenya– cost saving is paramount whilst safety is overlooked hence no housing box – look for welding goggles, fire extinguisher and other safety gear.

I have just spent a week in the field studying Masailand ecology and community conservation with Princeton University students. The location is not that remote (Kitengela and Olerai within 40 km of Nairobi) and the community are wonderfully resourceful when it comes to day to day tools for pastoralism.

Tractor tyre trough for water for goats and sheep

This old tractor or truck tyre was somehow cut, opened up and sealed at either end to make a perfectly good livestock watering trough. Even Joy Adamson noted that the Masai question using modern appliances if home made ones do the job anyway.

Another way to make  a salt lick, Evelyn just cut a truck tyre in half and placed it  on the ground supported by stumps.

home made bucket works perfectly

Why buy a bucket when you can just make one with an old water container and a piece of metal?

Home made shovel

And if you don’t have a shovel for your manure, just straighten out some corrugated iron, cut it and nail to a stick  and Presto – probably more effective than anything you could  buy in Nairobi. Manure is one of the few products sold to passing trucks on these remote ranches.

Keeping land open for wildlife migrations in and out of Nairobi National Park can be costly to those living with wildlife. Those in The Wildilfe Foundations land lease scheme earn 4$ per  acre per year to keep the properties open (no fences)  and to supplement their income they make beautiful beaded artworks for sale on Olerai Conservancy.

It might look like a tough life for some of us, but the Masai out here seem perfectly satisfied and at peace

In Baringo one farmer has come up with two rather interesting innovations.

Murray Roberts is in the business of planting restoring grasslands which involves planting grass seeds in severely degraded landscapes.

The primary purpose of ploughing is to turn over the upper layer of the soil, bringing fresh nutrients to the surface, while burying weeds and the remains of previous crops, allowing them to break down. It also aerates the soil, and allows it to hold moisture better.

A traditional plough comprises a series of blades all facing the same direction.

Murray Roberts has modified his plough so that it has two blades facing each other. These create a hill and furrow effect which is perfect for grass seeding to improve the trapping rainwater in this semi arid part of Kenya. Normally the rainwater hits the surface and sheets off the ground carrying away the valuable top soil and seeds!

But that’s not all. Ever tried to make a fence using barbed wire – you know how tangled it can get? Well not if you use one of Murray Roberts fencing gizmo, it’s basically a tool onto which you thread the barbed wire so that when you go out into the field to fence a plot, you can release the wire in an untangled manner and under tension.  Simple and obvious and you don’t need a wire tightening tool.

That’s William Kimosop and Princeton University Undergraduates checking it out – don’t ask  me what that dog is up to!

Here’s another interesting idea from Dominic Wanjihia (see links to his other gadgets below) – the fuel efficient Sufuria. A sufuria is the aluminium pan that is used by virtually everyone in Kenya to make tea, ugali and for cooking vegetables. Like all pots that we use, energy is wasted around the sides of the pot. In Africa this is expensive as fuel be it gas, kerosene or charcoal  is expensive.

This is what it looks like when assembled

This is what it is comprised of – two sufurias to make one efficient one. Basically a hole is cut out of the bigger sufuria – and the piece cut out becomes the lid so nothing is wasted. To wash the sufuria you just dismantle the pieces by just slipping it out. The heat that otherwise escapes around the edge of the pan, is trapped between the cooking pot and  it’s sleeve.

Though it’s not in production, Dominic is using this sufuria at home and swears that it saves at least 50-75% energy on a kerosene stove (his estimate is based on how long it’ takes to boil water).

So if you put a fuel efficient sufuria on a Kinyanjui fuel efficient stove I wonder how much energy saving you could achieve?

Dominic Wanjihia has been previously on Afrigadget showcasing his flat parabolic mirror, container garden, wearable Solar Panel vest, Food dryer, and camel milk cooler.

I love street food. Everywhere I go, from street markets in Russia, to back alleys of Beijing to side streets in Skopje, to the boulevards of Bamako, I make it a point to eat as many meals from roadside stands as possible. Ghana and Nigeria are no exception. In fact, I love me a MamaPut.

Its only where Mama herself is there to put more of her good eats on your plate, that I really feel I’m getting a good meal. Why? Because I can see ever step of its preparation, talk with the chief personally, and share the transcending bond of food with my fellow man and woman.

Now I wouldn’t call myself a street food expert – I’m not discerning enough for that title, but I am observant in the different styles of edibles vendors. In West Africa, I’m particularly impressed by the stock street food cooking apparatus. Simple, cheap, and recycled, I present to you the “Rim Stove”.

. .

Using the steel rim off a car wheel as the basic starting point, three metal legs are wielded to the outside of the rim. Inside, a metal grate is added to the bottom to hold in the coals, and some form of pan or kettle stand is wielded to the top.

I’ve seen several variations on this theme, but the basics are always the same – the Rim Stove burns charcoal that’s been ignited in the middle of the rim, fed by air from the bottom and heating a cooking container sitting either on the pot stand or the coals themselves.

During on extending brainstorming session, I even tried to think of improvements to the Rim Stove – how it might burn hotter with less customization. My only solution? Make sure a Rim Stove is cooking chips for your fresh grilled fish.

When Dipesh Pabari of Camps International sent me pictures of these laptop bags and bottle can holders, I just knew it would be something you AfriGadget fans would appreciate.

The fact that discarded waste is converted to something very useful… Its definitely AfriGadget. I asked Sander Den Haring a few questions about these cool products.

How did you begin your company?

I was born in a small town called Hellevoetsluis in the Netherlands but only lived there till i was 5. At that point my family moved to Yanbu, Saudi Arabia where i grew up and ended up spending 16 years. Yanbu is an industrial town situated on the Red Sea and i believe that a lot of the what, who, why and where i am is as a result of this. From the very beginning of our time in Yanbu my parents began a weekly outing to the beach which my brother and i eagerly anticipated every Friday (weekend is Thursday and Friday in Saudi Arabia). Once at the beach we would go out and snorkel virgin reefs in the Red Sea and be stunned by the serenity and tranquility each and every time. My love for the aquatic realm and the conservation of said realm has derived from these expeditions. It led me to complete a Masters in Marine Biology from the University of Groningen in the Netherlands in 2000 so that i could work in the field of marine conservation.

In 2004 i moved to Kenya where i have lived ever since. I began work for Buccaneer Diving as a base manager and soon added on the role of resident marine biologist. Under this capacity i was able to instigate a snorkeling program for some of the underprivileged local government schools in Mombasa (Schools to the Sea program) and an artificial reef program in the Mombasa Marine Park. Both these projects had local partners involved as well. I eventually finished full time work with Buccaneer Diving in June 2009 as the Operations Manager of Buccaneer Diving Kenya and currently fulfill only a part-time quality control position within all of Buccaneer Diving (Kenya and Zanzibar).

I really enjoy thinking of ways to create environmental attitudes and the recycled wetsuit product line has been great in achieving this thus far! We are still coming up with new products and refining the existing products. There are no limits barring our creativity.

What was the inspiration for re-using the diving wetsuits?

In the dive industry wetsuits have a finite lifetime after which they become ineffective (have lost their insulating capability), or they become too hole-ridden to use in a professional business. In the past, these wetsuits were discarded. This seemed an obvious waste of material (as for the sake of a few holes, large patches of usable neoprene were being thrown out), so Buccaneer Diving began looking at what could these patches of neoprene be used for. Traditionally we have used smaller bits of neoprene for various “odd jobs” (eg. snorkel holders, buffering/padding material, informal packaging, patch material for other wetsuits), but these “odd jobs” required small amounts that did not need frequent replacement. So we started thinking if there was anything else that could be made and the obvious item was laptop bags. The bottle/can holders soon followed suit as the sleeves and legs of wetsuits already had the obvious shape (they just needed a bottom added). We are currently making the products more of an “item” and also looking into how we can incorporate the production of these products to benefit other charities. these exciting developments will be happening within the next few weeks we hope so definitely watch this space (it’ll be worth it!).

When did you start selling the bags/bottle covers etc?

This is a new venture and its been active for the last seven months, so still very young. We are looking at various other items we can make from the recycled neoprene (placemats and coasters might be possibilities).

How much do the items cost?

Currently the laptop bags sell for Ksh 2500 (about 32 usd) and the bottle/can holders ksh 350 (about 5 usd)

Are they made in Kenya/Mombasa?

They are indeed produced in Mombasa. Again, the story behind the production will unfold in the next few weeks and its worth the wait.

Where can people order? Can they pay by MPESA (Mobile Money)? (Just kidding, but hey!)

These products can be purchased at the Buccaneer Diving base at the Voyager Beach resort, Mombasa. We have not yet explored the use of MPESA in the purchase of these products as they are still young, but who knows what the future will bring. We can also arrange for products to be sent via courier if people are unable to visit the Buccaneer Diving base. Sander can be reached via email sander at green-water [dot] org.
