A Tablet for Africa?

Guest post by Jay Cousins:

For many of you reading this, the title of this article might lead you to a vision of one laptop per child – or some other Silicon Valley vision of progress for Africa.

The technology I wish to discuss is slower and simpler. Full disclosure: it’s my invention.

The Betabook is a portable whiteboard, which can be used with a smartphone for archiving, content creation, and social media sharing.

During my time in Egypt working with the icehubs network, I tested the initial prototypes. Uses in this context included:

  • Translation – through drawings (and the written text of others) I’ve been able to communicate with Deaf Egyptians in Aswan and others who cannot speak English.
  • Improved communication – visual aids, allow for clearer communication of objectives or ideas
Part’s list for Air Quality Kit – Preparing for a Hackidemia workshop in Alexandria – see previous post for outcomes.
  • Note taking during field work, and archiving using my smartphone
  • Annotation of photos as a form of resource documentation.
A visual model of the problems of land inheritance in Egypt, along with potential solution.
  • Creating an illustrated children’s story with my wife (story by me, illustrations by Zeinab)
I found the Betabook to be an invaluable tool, and something I could share and use freely with my peers. Asking collaborators to “draw it for me” allowed for clearer communication, and easy creation of new ideas.

Three deaf brothers I used it with in Aswan liked it so much we decided to do a spontaneous workshop to show them how to make their own.

Early prototype showing difference between readily available plastic and custom created.

We used locally sourced plastic sheet – not as good as our custom material but enough for their needs.

I hope that the project can also serve as inspiration, demonstrating that Technology need not always be digital. This project started in a bedroom with a pair of scissors, and developed in the open.

An early prototype built from an old notebook, some plastic sheet and some tape using a pair of scissors.

Since the end of my contract we have funded the product on Kickstarter. I’m pleased to report it’s been enthusiastically received by the Egyptian Market.

We recognise the current price of the Betabook makes it less accessible to all tiers of the African market. To address potential demand we are making our material available for people to produce their own. We are also encouraging group buying to reduce postage costs.

For Hubs which already use new process models such as:

  • Graphic Facilitation
  • Open Space
  • Hackathons
  • Service Design Workshops
  • Business Canvas Workshops

The Betabook offers the opportunity to reduce long term material costs and generate additional income streams.

There are lots of discussions about localised production within various hubs and organisations. We can see the potential of local micro-businesses to profit from producing their own versions of the Betabook. We’re interested to connect with communities who upcycle local waste. Collaboration with local artisans could also lead to unique product offerings.

While its too early for us to get this network of producers up and running at this point, we are eager to gage the demand for this model. Please feel free to get in touch if you’d like to be one of the first to know when we are ready to take this conversation further.

SK8OPIA – Skate Ethiopia

These are great news from our Ethiopia-based partner iceaddis: a student recently designed a new wheel for skateboards that can be produced in Ethiopia – made and designed in Africa. Reinventing the wheel? Eh!

Bauhaus product design student Daniel Scheidler presented his bachelor project on affordable and locally appropriate vehicles for individual transport in Ethiopia. Through extensive field research in Addis Ababa, Daniel concluded that new roads of good quality have been built across the city and the country, but owning a car is still far too costly for the great majority of the population, while the public transport system (buses & taxis) on the other hand is overcrowded. Derived from personal experience in the skateboard scene, Daniel’s proposed solution is a locally adapted type of skateboard, as a viable option for the daily transport needs of the urban masses.

Of central importance to the concept is the wheel, which was especially designed for easy production with locally available materials. Up until now, any complete wheel on the Ethiopian market, be it for bicycles, wheelchairs or skateboards, has been an expensive import from abroad. Daniel’s prototype relies on a core out of spray foam insulation, cast with a reusable mold and supported by a fiberglass coating and leather or rubber from used tires. The wheel design is meant to be gradually enhanced and adapted through the iterative process of small-scale local manufacturing.

You are what you breathe

When was the last time you noticed the air you are breathing ? Do you know how it affects you and your health?

air pollution Egypt

Egypt leads the list of the most polluted cities in the world, in terms of particulate matter. Moreover, according to the latest report by the WHO, every Cairo resident’s daily share of air pollution is equivalent to smoking a pack of cigarettes a day.

This motivated the makers from icealex hub in Alexandria Egypt to work on solving this global problem.

Their solution: Build an air quality monitoring kit

afrimakers air pollution kit

The kit uses Arduino, gas, humidity and temperature sensors, RGB LEDs and an LCD screen to detect and measure air pollution. The Afrimakers team wishes to understand and map pollutants in their local environment and identify main pollution sources and best strategies of individual protection.

The idea was inspired by the Air Quality Egg project, which is based on Arduino, allowing anybody on the world to monitor CO2 and NO2 levels around his house, and share the results online, to be compared with the rest of the world records.

What distinguishes the prototype designed by the Afrimakers team from the AirQuality Egg’s, is the reduced cost and the outreach to local schools, communities of makers and learning centers for children. The same components of the kit can be used for many other projects which also reduces the investment for schools.

The team has a detailed documentation for this project and aims to create several learning modules for this project that could be used in schools and video tutorials.

This week, the project developers are visiting the makers in Nairobi and organizing a series of workshops in collaboration with Fablab Nairobi and iHub in order to improve their prototype and reflect about how it can be locally-driven.

If you would like to build your own air pollution monitor you can follow the instructions made by the icealex team. In case you don’t have access to the same sensors or materials we encourage you to “fork” their project here and and adapt it to your local resources.

A main goal of the team and their project is to encourage makers and local communities to dream, make and share meaningful projects that are solving big problems and are extremely affordable.

Blade-less wind turbine blows fresh air into power generation

A guest post by Kahenya, Founder of Simple Community

The name William Kamkwamba might not sound familiar to many, but he is one of the most significant technology game changers in Africa. He did not design the most glamorous device on the planet, and neither was his creation unique. However, it was extremely significant.

Using just a book, Kamkwamba, now 25, designed and built a windmill that generated electricity and pumped water in his home village in Malawi. This was significant because he proved that it was possible to build things with instant grassroots impact that did not require a business plan, a website, a marketing strategy, a funding strategy or even a glamorous launch. He gained instant fame.

Kamkwamba managed to ensure that he could meet his immediate power needs using tree branches and scrap material. He was able to generate electricity and pump water using pure green energy. That was a decade ago.

Enter the future and a decade later, we have the Saphonian Blade-less wind turbines – another African design, this time from Tunisia. It focuses on clean energy.

The inventing company, Saphon Energy, led by Mr Anis Aouini, understood that older generation turbines, built in Europe, had some fundamental flaws that no-one had resolved.

For one, they generated a lot of noise and vibration. There is the unmistakable whirring, and if you live next to one, unless it is not in motion, you could have sleepless nights before getting used to the sound.  They also unwittingly kill a lot of birds. Unaware birds collide with the blades and get killed.

Not the Saphonian. It has a sail shaped body, similar in concept to sails on a boat or dhow, which makes it bladeless. The unit does not have the famous rotating blades common with older generation turbines and windmills. Even better, the advantages are not limited to aesthetics or providing environment friendly energy. The Saphonian eliminates inefficiencies usually created by moving parts in a windmill.

The lack of blades and other rotating gears means that there is very little aerodynamic energy, and this results in improved power generation. It also reduces mechanical losses. Thus, the Saphonian has been found to be about 2.3 times more significantly efficient than conventional turbines and windmills. It also means that due to the hydraulic system, the Saphonian is able to store energy, which enables it to supply a steady flow of power, provided there is wind flowing or there is energy stored in the system.

In ordinary systems, whatever is generated has to be consumed instantly. National power grids usually supply the exact amount required. This means that when demand exceeds supply, there will be some places without power. On the other hand, excess energy, not being stored, would go to waste.

The storage capability of the Saphonian is therefore significant. Further, the equipment is cheaper to produce than conventional systems. It costs 45 per cent less to develop and deploy a Saphonian Blade-less turbine. With customisations, that cost could be further reduced.

Saphon Energy has tested a 300–500 Watt system as a prototype. It has performed better than was anticipated. The company is now focused on developing a second generation prototype that in many instances, will improve on the hydro-mechanical performance of the first generation unit.

What will matter for this development and its growth is how many national electricity providers deploying wind infrastructure decide to use this more cost effective technology. The Saphonian has proved that Africa can actually improve on previously available technologies that were not as efficient as they could have been.

For William Kamkwamba, this would be a climax to his dream, that affordable energy solutions developed in Africa could actually compete with foreign platforms and even outperform them.

As Africa struggles to meet electricity needs for a growing population, it is necessary for the continent to develop its own home solutions suited for the environment and the pocket. Convenient and relevant innovations such as the Saphonian stand a good chance.

It is no wonder therefore that the Saphonian has won its parent company the KPMG innovation Grant for 2012.
