Recycling car batteries in Rural Kenya

Maina, Rhoda and little Winnie are  a typical Kenyan family who live on the outskirts of Nairobi in an area that has no electricity.

But they have solved the problem of getting the daily news

When I visited their home I was impressed that despite the lack of electricity, Maina has come up with an innovative solution and is able to keep up with whats going on and listen to his favourite Kikuyu music all day long!

Here’s a better look at the system – a second hand car battery hooked up directly to his radio

The wiring is simple

Fully charged the battery last 2 weeks. To recharge Maina has to take it to a place in town for 24 hours at a cost of Ksh 50 (about 80 cents US. If he were to  use ordinary batteries Maina would be paying several hundreds of shillings per month (15$) and creating toxic waste with their disposal (Kenya has no battery disposal system).  No wonder used batteries are in such huge demand!

And no wonder this family is smiling!

I’m wondering how much it would cost to hook up Mainas battery to a solar panel and  some lights. They currently depend on hurricane lamps.  Powered with kerosene these are not only a weak source of light but are dangerous and prone to cause fires.

Got any ideas anyone – can we charge a car battery from solar?

AfriGadget and the solar FLAP bag project

I’m scrambling to put my bags together for Ghana, as I leave in just a day for Maker Faire Africa. There’s only one problem, I don’t have everything that I need, and I’m waiting on a shipment from a California bag company. The good news: I’ve just been told that I’m no longer sworn to secrecy, so I can begin telling the story. Here is the FLAP bag project story (from my perspective) and AfriGadget’s involvement in it.

A little background

Four months ago the Pop!Tech team approached me about their collaborative project with Sheila Kennedy of the Portable Light project, who showed off her solar TB blanket at Pop!Tech 2008, and Timbuk2, the well-known messenger bag company.

FLAP bag project companies

Their plan was to develop a bag that has the potential to bring the benefits of portable power to selected global communities around the globe, and they were hoping the I could help with distribution and testing within the African communities that I frequent, where power is crucial. Of course, I jumped right in, this was just too intriguing to not do so, plus I have great admiration for all of the players: Pop!Tech, Timbuk2 and Sheila Kennedy.

The FLAP bag project

FLAP stands for Flexible Light And Power. The flap on the messenger bag has the single solar panel on it, connected to the tech tray, which has an on/off switch, an LED light and a USB connection. So, in concept, the bag can be used as a portable lighting and power supply unit for anyone. Most useful however, to those lacking consistent power for devices or an electric lighting option.

This bag will be the official Pop!Tech 2009 bag, and will also be sold by Timbuk2 sometime after that. It’s a unique bag that has the potential to change the way a lot of people (not just in Africa) do things. I don’t have detailed information on any of that, so look to the Pop!Tech team for more information on availability.

AfriGadget’s part in this

Due to my fairly extensive travels, dealing with just the right cross section of potential users for the bag, I was in the right place to distribute some test bags for feedback from end-users. My job, over the next three weeks will be to find the right types of people to give a bag to, interview them before and after, and report back on my findings.

My first stop is Ghana, then on to Kenya and Uganda. I have 10 FLAP bags, with plans to hand out 4 in Ghana, 4 in Kenya and 2 in Uganda. To do the interviews, I will have the help of Henry Addo in Ghana (also a colleague or mine at Ushahidi), and with David Ngigi in Kenya (a young videographer and friend). Pop!Tech has supplied us with small video cameras that we’ll be using for the interviews, as well as some starter questions and types of individuals that they would like to see get the bag.

My objective is to find people from many walks of life, from taxi drivers to citizen journalists, and from roadside food ladies to seamstresses. One of my questions is this: can much of this bag be created from locally available materials?

My main goal: find out if it is useful, usable and if its adaptable to everyday life in Africa.
The Challenge: asking people how they would adopt these kits, looking for inventiveness.

I won’t be sugar-coating my own reviews, nor those of the people who we interview.

Tune in for more tomorrow

My next post will be pictures of the kits, unboxing of the items that I have received and my initial opinions on them. I’ll also be doing some personal interviews (video diary) of myself throughout the weeks ahead, giving some insights into the day’s events and overall thoughts on the FLAP bag project.

[Update: Day 1 video diary]

I’ll also be using Twitter for updates, and though I manage the @AfriGadget account, when I get on the road I usually just post from my personal @WhiteAfrican account.

Additional updates from the manufacturer and from the project team will be found on the Pop!Tech blog and the Timbuk2 blog from time-to-time.

Harnessing Personal Movement for Power in Rural Africa

Dr. Cedrick Ngalande is an inventor. He’s been working on inventing new ways for everyday rural Africans to create enough electricity to power items like mobile phones or other small electrical devices. In the past, he’s been on AfriGadget for his yeast + sugar rotary electricity generator.

Today he has announced a new project called Green Erg, which harnesses (literally) a person’s movement energy to create electricity.

Harnessing Personal Movement for Power in Rural Africa

“This is basically a dynamo which is being driven as a result of friction between the ground and the blocks. The small yellowish blocks (these are covered by rubber in the real commercial product) rotate as you pull it. They are designed to rotate even on bumpy run even roads. We have tested it on moist lawn and have worked. It is very smooth so much that you basically don’t feel any disturbance as
you move along.

At normal walking speeds we have gotten more than 2 watts which is more than enough for running cell phones or radios. I envision that people will attach this to themselves and walk with it – or even attach it to an ox-cart, a skating board, bike, etc.”

AfriGadget Innovator Series: Simon Mwacharo of Craftskills

I recently had a chance to conduct an email interview with Simon Mwacharo, an entrepreneur based in Nairobi, Kenya who a great example of what George Ayitteh has so aptly described as “The Cheetah Generation”.

Simon owns and runs CraftSkills, a small business based in Nairobi, Kenya that focuses on designing and building self-sustaining renewable energy projects in places not accessible to the electric grid. Craftskills had to date undertaken challenging projects in Kenya, Uganda, Tanzania, Cameroon and Rwanda among other places. Simon, whom AfriGadget first got to meet last summer at TED Global in Arusha, Tanzania, graciously agreed to conduct an email interview with AfriGadget.

Craftskills windmill project

AfriGadget: Could you tell us when and how Craft Skills got into the business of renewable energy in East Africa and the inspiration behind the organization?

Simon: CRAFTSKILLS was found in the year 2000 by myself. I was inspired by a challenge from my rural home where we have not had power for the last 40 plus years since [Kenya's] independence [in 1963]. I come from a hill side village in Sagalla, Taita Hills in Coast Province where we receive quite some strong wind from the Nyika Plateau. This wind passes through without being tapped and sometimes our roofs can not stand in its way.

I started talking to people about wind turbines and how I can get an affordable one which I can make and produce for other needy people. When darkness falls in these villages plus the fog it is virtually impossible to travel the terrain at night.

AfriGadget: Tell us a little about the people behind Craft Skills and the staff who work for the organization.

Simon: I started with two workers. I could not afford to hire trained people so I decided to train myself first then train my two boys. Then I got a friend who repairs radios and TVs in Kibera to help me design and put together a charge controller.

Now we have a team of 20 people and other partners out there in the field with their staff totaling 50. We have technicians, welders fitters, fiberglass experts and engineers and sales people.

AfriGadget: What is the typical profile of a Craft Skills project? Who is your typical client and how are the projects typically executed?

Simon: Most of our clients are not the owners of the projects we put up. They benefit from the battery charging services in the wind/solar sites we put up with our partners. The low income earners who cannot afford grid power or are in settlements where grid power is unavailable. We take both to do the sites ourselves involving the people on the ground as partners. Others are home owners who have invested a lot on building good homes in non grid areas – these put up turbines for their own use like lighting, and pumping water from wells and boreholes. The other segment is the business people I market areas where there is no grid who put up turbines to run charging centres and sell power to other shops or run their off-grid businesses like lodges and hotels, schools and other institutions.

AfriGadget: Can you share with our readers some of the challenges that Craft Skills faces in executing your projects?

Simon: We have faced cultural challenges where we cannot put a turbine on the most ideal site due to beliefs on such sites hence we have to educate the citizens to allow us to do so or redesign the project and relocate. Another is the financial capability of the citizens we find in these off grid areas.

[As a result of this] we have designed low power product (battery bundles and LED lights) to reach them so that they can be counted as beneficiaries of this new technology.

AfriGadget: Why renewable energy? What is the rationale behind Craft Skills’ exclusive focus on projects that produce energy from renewable sources.

Simon: We were looking for something which is affordable and sustainable and cuts across the economic sectors. Solar was proving to be more expensive, delicate, sophisticated and easily stolen when installed on ones home. We needed to sell people more power at a cheaper rate hence wind was the best candidate.

Wind is everywhere just like solar – one needs to get the right spot to put the turbine as high as they can. Its 24 hrs (Day and Night) and we found a cheap way we could make our turbines take advantage of low wind situations with the multi-pole generator, hollow blades for the propeller, with 90 per cent locally available materials making our technology the best application for this region.

AfriGadget: Which would you say has been the most satisfying/gratifying project that you have been involved with at Craft Skills? What was so special to you about this particular project?

Simon: The Chifiri water pan project to me is most gratifying. This settlement is all arid land pastoral community. The demand for water for drinking washing and watering the thousands of livestock is enormous.

Our turbine provided a cheaper solution for water and lighting the “manyattas” around the water pan. The contractor on the ground is excellent on his construction of the earth dams. His design impressed me that water was going to be available for over 6 months instead of the normal 4 months after the rainy seasons. He made sure the dams were well compacted and fenced to avoid animals hoofing inside the dam – increasing the rate of percolation and lose of water in the ground. Water is only available at the kiosks which are piped and placed near the settlements. The project provides water troughs for the animals to drink from and bathrooms for the people to clean themselves in. Within the fenced dam there is an armed home guard or caretaker manning the place with a security light up the tower hoisting the turbine.

Powering African Schools with Playground Toys

Dan Sheridan and his see-saw power idea for African schoolsThe BBC is running a story on a young inventor, 23-year old Daniel Sheridan, who has designed a teeter-totter (see-saw) that can be used to power school classrooms in Africa. His ultimate goal is to see a whole playground of energy-creating equipment.

“The current need for electricity in sub-Saharan Africa is staggering. Without power development is extremely difficult. The potential for this product is huge and the design could be of benefit to numerous communities in Africa and beyond.”

The idea came about after travels to East Africa, where he taught at a school and was inspired by the students. Daniel developed the see-saw power design as part of his final year at Coventry University. He has calculated that five to 10 minutes use on the see-saw could generate enough electricity to light a classroom for an evening.

Some Thoughts
What would be more interesting would be to see this idea built out with local supplies, as Daniel is going to be doing soon in Uganda. Then, with the knowledge learned there, see if it could fall into the same model of micro-entrepreneurial devices that we see with the KickStart water pumps. Speaking of which, this also reminds me of the PlayPumps idea, which also has a lot of potential.

Daniel states, “The unique selling point of this product is that it is not intended as a profit-making design.” I can only hope that he means this as profit for him. Profit making on the ground by Africans of this type of design could be crucial for its long-term success.
