Artificial intelligence is seen as an advanced and dangerous technology, but IBM is showing how it can help solve problems for Africa, writes ARTHUR GOLDSTUCK.
Artificial intelligence has been getting a bad rap lately. It’s been blamed for the way Facebook and Twitter promote fake news on the basis of showing people more of what they are already click through to read. That in turn is credited by some with handing Donald Trump the US presidency. It’s also been blamed for introducing bias into anything from home loan approvals to facial recognition systems, which tend to be more accurate with Caucasian faces than those of others.
But a team of scientists at a research facility in Braamfontein, Johannesburg, hopes to change all that.
“We are working on beneficial AI,” says Tapiwa Chiwewe, a scientist at IBM Research, which opened its second global research lab in Africa at the Tshimologong precinct in 2016. “We want to create AI that benefits people. In Africa, there are all kinds of socio-economic problems and we’re in a unique position to create AI that improves people’s lives. But we also want to create economic and social value.”
The emphasis is not on AI for its own sake, or operating independently of humans, but on creating symbiotic systems that help humans perform their roles better.
“These range from data driven healthcare to digital urban ecosystems,” says Craig Holmes, vice president for Industry Solutions and Business Development at IBM Middle East and Africa. “We’re researching air-quality management in partnership with the city of Johannesburg and Tshwane, we’re looking at traffic management in cities, and even wildfire risk prediction in the Cape Town area.”
Many of these projects will deliver benefits in the medium- to long-term future, but at least one is ready to roll out. It will be launched this Sunday, April 22, marking Earth Day. Appropriately, it is aimed at promoting sustainable energy.
It’s called EmpowerSolar, and is a web-based application for designing solar powered solutions for domestic and business use.
IBM explains on the site: “The app uses a sophisticated algorithm to determine an optimal solution, along with an estimated price based on current typical prices. The algorithm takes into account the amount of sunlight at your chosen location, along with the specified usage of the various electrical appliances chosen.”
The app was developed by Dr Ashley Gritzman, a young scientist at IBM Research. By coincidence, he had graduated as an electrical engineer and was an installer of solar systems before joining IBM.
“I had a small startup, assessing people’s energy usage, monitoring household or small business consumption, and told them how to reduce their energy use, ranging from changing old light bulbs to LED, to using solar geysers for water heating. Then we’d spec the systems, and design and install. I saw there was a big divide between home owners who may want energy efficiency, and the knowledge of installers and retailers of the technology.
“When I joined this lab, they asked, what contribution can we make to the energy question in South Africa? I saw a big gap of information. For example, solar is regarded as way too expensive for many and they wouldn’t look at it. But in fact, people have no idea what it will cost. If they assume it will cost hundreds of thousands of rands, they won’t even pick up the phone to enquire. I wanted to bridge the gap between homeowners and new technology.”
Part of Gritzman’s motivation was the dramatic fall in solar costs: the price of panels has fallen 50% in the last 5 years. The Renewable Energy Independent Power Producer Procurement (REIPPP) programme, designed to encourage private investment in renewable energy, has seen contract prices fall from R4 to 65c per Kilowatt Hour since 2011.
“South Africa has great resources in both solar and wind, and there is no longer a question that it is cheaper than new-built coal or nuclear. But it has to be super user-friendly, so that my parents can use it; it has to be technically accurate and pricing has to be correct, or else it’s not useful. And the electrical designs it comes up with have to work and be correct.
“When I was doing the solar stuff myself, a design would take a lot of time and a lot of calculations to do an initial quote. Then they also want to run the garage lights, for example, and you have to redo it. The app will be useful to home owners, but also to installers to do a quick design and costing.”
Gritzman’s PhD was in machine learning and image processing, which fits in perfectly with the artificial intelligence focus of the Research Lab and IBM’s Watson AI engine, which has been used for numerous medical breakthroughs, ranging from cancer research to tuberculosis treatment. However, EmpowerSolar fed a personal passion, and he was quickly able to drive it from idea to reality.
“It’s a responsive web site, it looks like an app, but doesn’t have to be downloaded. You choose your location, and we ask a few questions that are easy to understand. The big difference is in how much sun you get. We’ve got little sliders, and ask people to use those to select direction, angle of roof and appliances they’d like to use with solar energy.
“When I was an installer, we’d just say how many kilowatt hours do you use a month, and most people don’t know. So we build this from the ground up, with categories, like home office, kitchen, and lighting, and within each we have a database of generic appliances.”
Part of the purpose of the service is to promote energy-efficient behaviour. As users indicate the appliances they use, messages pop up that, for example, advise that an electric geyser uses a large amount of electricity, and indicates the cost and benefit of installing gas or solar. Nothing is hidden. The application includes costs for solar panels, batteries, charge controllers, inverters and installation costs.
Gritzman is as enthusiastic about South Africa’s advantages as he is about solar power.
“South Africa really is sunny. If you compare us with Germany, one of the world leaders in solar, the least sunny spot in South Africa still has more sun than the most sunny city in Germany. That puts in perspective what opportunity we have.”

Showmax launches half-price mobile streaming service
A new streaming product designed specifically for Africa, featuring TV series as well as African content and live sport, is aimed at filling the gap in subscription video on demand services
The subscription video on demand (SVoD) model, which originated in the USA, spread rapidly in countries where uncapped broadband is affordable and widely available. However, because the model also relies on consumers being comfortable with transacting online and having ready access to credit cards, it has barely scratched the surface across Africa.
On top of that, smartphones are often the only only form of Internet access across Africa, and none of the popular SVoD services have been designed for the format.
Showmax says it plans to change this with the launch of a new mobile plan that costs 50% of the standard Showmax package but still features 100% of the same video content. Showmax is set apart by a combination of four pillars: hit African content, exclusive international series, topkids’ shows, and live sport, including weekly matches from the English Premier League, Italy’s Serie A, and Spain’s La Liga.
Showmax says the new plan is aimed at consumers who only use smartphones and tablets to watch video content. Video resolution peaks at standard definition to help reduce data consumption. As it is a product aimed at individuals, only one concurrent stream is included in the plan. As with the regular service, it is also available for a 14-day free trial.
“This is all about an African service developing a solution that meets the needs of African consumers,” saus Niclas Ekdahl, CEO of the Connected Video division of MultiChoice. “Customer feedback consistently points to local content and sport as some of the things that people value most from Showmax. That’s of course on top of the international series, movies, and kids’ shows that are our bread and butter. With all of that content now available in a product designed specifically for mobile usage, we’re doing something no other service can offer.
“On top of that, with groundbreaking deals like our new offer with Vodacom in South Africa, we solve the credit card issue through add-to-bill payment and the data issue by including data directly in the package. We’re looking to launch similar offers in Kenya and Nigeria soon.”
Both the standard and mobile plans include live sport, sport magazine shows and sport documentaries. The 2019 Rugby World Cup Final was streamed live on Showmax earlier this month, and the following is a selection of some of the football due to be live-streamed in November:
22 November: Levante vs Mallorca (La Liga)
23 November: Arsenal vs Southampton (Premier League)
24 November: Bologna vs Parma (Serie A)
25 November: Aston Villa vs Newcastle United (Premier League)
29 November: Celta Vigo vs Valladolid (La Liga)
30 November: Fiorentina vs Lecce (Serie A)
30 November: Chelsea vs West Ham United (Premier League)
Showmax’s mobile plan is currently available in Nigeria, Kenya, and South Africa.

Online series wins SA’s Journalist of the Year award
A series of stories on gang warfare in Hanover Park earned Tammy Petersen of News24 the ultimate prize in South African journalism. Here are all the winners of the Vodacom Journalist of the Year awards.
At the 18th edition of the Vodacom Journalist of the Year Awards held at Vodacom World earlier tonight, News24’s Tammy Petersen took top honours and the R100,000 grand prize as national winner for her body of work on a gang war series entitled When you live in Hanover Park, you know death. Petersen’s submission was one of over 1,000 entries received from around the country across 12 categories – Investigative, Opinion, Lifestyle, Photography, Sport, Economics, Politics, CSI, Live reporting/ breaking news, Data Journalism, Multi-platform and the Young Journalist of the Year Award. This year’s theme – Connect the Dots – pays tribute to the best-of-the-best of those entries.
Takalani Netshitenzhe, Chief Officer for Corporate Affairs at Vodacom Group says: “This year has seen extraordinary entries to the 18th Vodacom Journalist of the Year Awards. Not all the stories that are national winners were about huge events but also showed the importance of telling the stories of ordinary people. In line with our theme, the dots were indeed connected, and we congratulate all the winners.”
Convenor of the judging panel Ryland Fisher says: “The quality of entries has convinced the judges once again that our industry is in good hands, as far as journalism is concerned, despite the many problems that have beset the industry in recent times. Judging from the entries, South African journalists are determined to fly the flag high for a free, independent, and vigorous media, which augurs well for our democracy. As judges, we can only salute all the entrants for the great work that they submitted. In the end, our industry is probably the biggest winner.”
Judges for this year’s awards are: Ryland Fisher (convenor), Jermaine Craig, Arthur Goldstuck, Albe Grobbelaar, Franz Kruger, Patricia McCracken, Mapi Mhlangu, Collin Nxumalo, Mary Papayya, and Obed Zilwa.
