Fuel saving Sufuria

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. sufuria 1

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?

Rim Stoves: Cooking MamaPut Goodness

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.

An Oven Made From a Blockbuster Drop Box

The following story came in from Luca Varaschini (by way of David Sasaki) who was born and raised in Robertsport, Liberia where his father was a doctor. He now lives in Milan, Italy, but was in Robertsport a couple weeks ago for the first time since he left as a child.

During my first week back in Liberia I had been invited to Hawa’s birthday party, on Sembehun Beach, not far for Robertsport, so I passed some time with the ladies while they were preparing western-style food for everyone: rice, beef stake, pasta and potato salad. Then they started stirring what would have to be two cakes for the dessert, and I started wondering how they’d be able to bake them, since the only cooking apparels in the big warehouse were these coal pits on the ground.

They showed me the oven, a big metal cabinet against the far wall; looks like a refrigerator on legs, to allow a coal pit to fit under the bottom, but when I get near it, I see it’s a Blockbuster Quick Drop Booth! The front, where the slit had been closed, faces the wall and the back door is to access the oven; inside are several fridge trays, on which they lay the pans. The door is then locked with a simple bolt and sealed all around with wet cloths.

The cake was fabulous.

[Editor’s note: I’m find myself incredibly curious trying to figure out where they found this… How did a Blockbuster drop box get to Liberia?]

Jiko Production Using Gas Cylinders

Bush camping is one of the greatest pleasures of living in Kenya – only if you have the right equipment. On a recent hastily planned trip to Lake Magadi hot springs we discovered too late that we’d forgotten the jiko (charcoal cooking stove). Stopping in Magadi town which serves only one industry, the Magadi Soda Company, we had one made for us right there and then in a very active jua kali workshop.

I always wondered where the metal for jiko’s came from – In this the many discarded gas cylinders are chopped into segments to make up the body of the jiko.

There seems to be no power shortage here, a mess of electric cables and metal and wooden waste remnants from the soda company is an active business for about 20 artisans making furniture, gates, and jikos for the staff of the soda company.

A ten minute job turned out into a one hour event and a thousand shillings later ($20) we take off proudly with our extremely heavy stove. That’s when we discover that there is no charcoal to be had in this part of the world anyway. We ended up with a 3 stone fire.

At dinner time we realized that we’d forgotten most of the food anyway (camping note to Paula: don’t believe him when he says “I already put it in the car” ).

Nevertheless, the hot springs were fabulous.

Don't believe Lonely Planet's version of the hot springs as "tepid"  - it was excruciatingly hot
Don't believe the guide books version of the hot springs as "tepid" - these springs are excruciatingly hot

The Jiko came home and has not yet been used – and thinking about it now … should I be worrying about cooking on something made from gas cylinders? Is it just iron or could there be lead in this?
