Solution for Nairobi Blackouts

It’s no secret that Kenya’s rivers are running dry as a result of forest destruction and environmental degradation which has led to a season of blackouts in the capital city Nairobi.

Typical of the ingenious people of Nairobi one street vendor has cashed in on the crisis with this wonderful gadget which he markets as

“Perfect for Nairobi black out”

As you can see I could actually read by the light of this lamp which is made from a used tin can, some pieces of wire to make the connections

And the battery compartment is ingeniously crafted from a circle cut from a retired flip flop.

I love my juakali lamp and everyone that I know  in Nairobi needs one of these lamps. Everything about it is so true to the juakali spirit – hand crafted using colourful recycled tins, and designed for a real purpose with a handle so you can move it around from room to room or hang it up. The vendor tried to sell it to me for Ksh 350 but we settled on Ksh 200 (about $2.50) though I’m sure he would have gone cheaper but the traffic was moving and I had to go.

If you want one visit the Nyayo stadium roundabout.  They stood out amongst the chinese junk that vendors are selling you could practically kit out your house from the junk on sale there. Here’s a short list of what I saw during my 30 minute traffic hold up:

Pens, hats, footballs, blow up spiderman (who needs one of these?), peanuts wrapped in newspaper cones,

smelly car things, driveres licence holding cases, scarves, giant maps, Kenya flags, apples, kits (spiderman kites),

Nike shorts, cowboy hats, socks, oanges, backpacks, cheap watches, key chains knives, olympic medals (yes I wanted one of those!),

knee length shorts for guys who sag, hazard ttriangles, cables to cack your car, name tags for meetings, torches, window wipers (!),

car mats, pears, plumbs, tiny folding chairs for children (or Chinese people?), vehicle number plates, fire extinguishers, stickers,

Enormous framed pictures of furry cats and snow leopards (I can just see one of these this in my house), bananas and bandanas, plastic lunch boxes, pillows and cussions, a huge variety of stuffed toys,

posters with Jesus’ sayings, polo shirts, stearing wheel covers, spanners, screw drivers and of course my favourite – juakali lamps.

Nairobi never fails to impress. I love it. What else have you seen on sale in the Nairobi streets?

Re-using plastic containers in Kenya

While hiking in the rift valley recently I came across a cow wearing this plastic gadget on his nose. It’s made from an old plastic container …..the local herdsmen said it was to stop him from suckling his mother – which is especially critical due to the severe drought in the region.

Simple and effective I’d say!

And here’s another one from Dominic Wanjihia – he calls it his vertical shamba

and it’s water efficient and space conserving… perfect for a tiny yard.

Here’s another clever use of plastic water bottles – bird feeders are impossible to find in Kenya

So Maina Maina fabricated this at Kitengela Glass where virtually nothing is thrown away

These feeders have pieces of mirrors attached and attract a huge assortment of birds at all times.  He’s selling them at Ksh 200 (US $2.50 )

MFA: Water bag design challenge!

Amy Smith (of MIT’s IDDS) somehow got a hold of a mic and madhouse has now ensued! Everyone has been split up by their birth month into groups. They are given 5 water bags (sachets) and told to solve the world’s greatest problems. 30 minutes later we get…

5 Bag challenge

January: The Sachet Kebab
Decreasing litter and polution. People can collect water sachets off the ground easily with a pole and spiked end. It can be placed along the roads, and a lot of trash can just be spiked on the tip of it.

February: Hydro Electric
Generate electricity by using the bags to create small turbines.

March: Light absorbent and heat absorbent bags
They also had a crazy idea of drinking the water, peeing in the bag and selling that to farmers for fertilizer… to much laughter…

April: Potting and a Wallet
Drink the water and make it empty. Cut the top off and put in soil and grow small plants. Take another bag and put a small hole in it for drip irrigation. Second idea: use the bag to put your money in for when it rains.

May: The individual water-shower packet and a purse
Hang the water and put a small hole in it. Create a purse out of it to hold a camera or mobile phone.

June: Waterbelt, glasses strings
They’ve created some really interesting spectacle (glasses) holder. Also, a waterbelt to hold the water as you’re moving around.

Maker Faire Africa: Ghana 2009

July: Water purifier
Uses the light from the sun to help purify the water. It takes a bottle top cut off and used as a funnel as well. It’s shaped like a train, for marketing reasons.

August: Kids toys
Make small airplanes and hats for children and an hourglass made from 2 water bags.

September: Drip irrigation and a pillow
Puncture a bottle or a bag on top to collect water, then use for drip irrigation. Also fill multiple old empty bags with air and put them inside a pillow case to create a pillow.

October: Drip irrigation
Starts with a bag, then a tube made of old empty bags that can direct the water further and over more areas.

November: Water resistant mobile phone case
“Your phone case is not water resistant, ours is. Clap for us.”
“We have created a water wallet, not just a plastic money carrier.”

December: Water sachet lighting system and a sachet wrist watch band
Put full bags on your roof that diffuses the light and warms the water.

Charging mobile phones with bikes and scrap

Just last week two African inventors won recognition for inventions that involved scrap, bicycles and mobile phones.

William Kamkwamba grew up as a farmer in Malawi, at the age of just 14, he had built his own wind generator.

During a drought his families fortunes collapsed and he spent his time in libraries reading and discovering about wind energy. He found components for his invention in a scrap  yard; a tractor fan, shock absorber, PVC pipes and a bicycle frame.

When his prototype was able to run four bulbs people arrived to charge their mobile phone. William has just appeared on TED  Global conference in Oxford this week to the conference to tell the audience how he did this.

Another inventor has already appeared on Afrigadjet and has just been discovered by the BBC. Pascal Katana, 22 who with Jeremiah Murimi, 24, has gone beyond fish and has invented a dynamo-powered “smart charger” to help people without electricity in rural areas to charge their cell phones. The system costs $4.50 and it takes an hour to fully charge a cell phone.

These two young men developed the idea during summer break. Wish I had so much energy in my holiday.  These guys should be at Maker Faire in Ghana this August.
