A group of university students and lecturers are on a road trip of a different kind as they travel over 4 000km to test out their solar powered car – the Ilanga II fuelled only by the sun, writes JENNI EVANS.
Solar panels? Check. Ion batteries? Check. 3D printer for spares? Check. A group of university students and lecturers are on a road trip of a different kind as they travel over 4 000km to test out their solar powered car the Ilanga II fuelled on nothing by good old sunshine.
“It can do up to 140km/h,” says Nickey Janse van Rensburg, who lectures mechanical engineering at the University of Johannesburg’s Energy Movement lab.
“Because we don’t have a lot of sun today we are doing 90km/h,” she said from the convoy snaking toward the Northern Cape town of Kimberley to show off the vehicle named after the Zulu word for sun.
And every time they stop, they draw a crowd of people keen to see what can be done by a group of bright sparks looking for clean green alternatives.
Resembling a cross between a space pod and a yacht, the aerodynamic lines of the orange and white Ilanga II draws delighted crowds wherever she pulls up. And that is exactly what the university wants – for people in the towns and rural villages along the route to see how green technology can be used in every day life.
Says Janse van Rensburg, the Ilanga II could even be plugged into a wall like a cellphone, if needed, to charge.
The Solar Car Project promotes the study and development of efficient energy use, environmental awareness, energy management and innovative engineering.
On Thursday the residents of Klerksdorp who arrived with their children at the team’s leg-stretching and system-tweaking stop at the Mitsubishi garage were intrigued by what they saw. Her “engine” is 300 lithium ion batteries which work almost like cellphone batteries, and almost 1 000 business card-sized thin solar panels.
Along the route, even mayors have come out to welcome the team which is happy to explain how everything works and tell people about other ways of using “green” technology in their every day life.
And of course, everyone wants to see some laps and they are not disappointed. And then it’s go time again.
Warren Hurter, engineering project manager at the university’s manufacturing research centre, is one of the three drivers taking turns on the test run.
He explains that the solar panels on top of the vehicle convert the energy from the sun into power in the battery packs.
The solar panels are similar to the solar cards that powered the Mars Rover which wheeled around the red planet looking for signs of water activity, its solar panel “wings” capturing enough energy during the four-hour Mars day to enable it to explore, and communicate with the team on Earth.
The Ilanga II’s tool box is a 3D printer which will be used to replace parts it might need for running repairs. The 3D printer has already produced the steering interface, the buttons, the battery holder and the brackets for the roof panel.
“We haven’t needed to use it as yet,” said Hurter.
They have had a small suspension problem so far, and when they started their journey in Johannesburg the telemetry system which measures the car’s performance was playing up.
“But that’s all part of the experience,” says Hurter who says he was the kid who played with Lego and pulled things apart to spend hours figuring out how to put it all back together again.
Camping along the way they have a support team which stays up until late making adjustments to the vehicle.
The Ilanga II is their third solar-powered car after the Ilanga and the Ilanga 1. Their team hopes to take her to next year’s Sasol Solar Car Challenge where the Ilanga 1.1 scooped the Technology and Innovation Award previously. Local and international solar car developers compete in that race between Pretoria and Cape Town as part of their work on improving the technology and to share ideas.
The race to find energy efficient alternatives has already given rise to the electric hybrids already on the consumer market.
Because the Ilanga II is built around efficiency, it only takes one driver. The team scanned the shape of one of the drivers, placed it into the vehicle and built it around his shape. So only drivers with his shape will fit into her.
The department partnered with UJ’s Prof Vivian Alberts at PTiP Innovations, who developed and internationally patented the thin film photovoltaic technology used on the car. These are very thin solar panels which they hope to pilot in rural communities in the near future, according to the university’s website.
Hurter says the car does not have any luxuries apart from indicators and headlights. The only radio is the two-way radio the team uses to communicate. It is a bit noisy on the inside because it does not have the sound padding that cars usually have, but from the outside, it is very quiet, and has no emissions.
The project has sponsorship from companies such as Eskom and Siemens, and a support convoy provided by Mitsubishi which also wants the crew to log their vehicles’ fuel efficiency for its own studies.
And when will be able drive one? Not in the near future. The Ilanga II Solar Car Project is not being built for sale, but for now is being used to research and develop sustainable and green engineering that can be used in the real world.
They already have plans to introduce the technology to power village pumps.
Spectators can look forward to seeing Ilanga II at pit stops and lectures along its route which will include a trip through Namibia and Botswana.

How tech is keeping us young
Research by Lenovo revealed people who use tech feel, on average, 11 years younger.
Technology is making the world feel younger, healthier and more emotionally connected, reveals new research by Lenovo, suggesting a growing relationship between technological innovation and wellbeing.
The research, which surveyed over 15,000 individuals from around the globe, from the US, Mexico, Brazil, China, India, Japan, UK, Germany, France and Italy, not only found 40% of global respondents feel “a lot” or “somewhat” more youthful thanks to technology, but on average it made them feel younger by 11 years.
This rings most true in China, where 70% of Chinese respondents said technology made them feel more youthful, which could be perhaps due to technologies ability to build connections between generations, especially those who might have once felt disconnected from tech-savvy youngsters. For example, grandparents are now able to better communicate with their grandchildren via smart technology due to its growing ubiquity and ease of use.
The research suggests that this sentiment is felt world-over, across genders and ages. “To know how to operate newer technology makes me feel younger” one US woman, said. Another woman, from France, also stated, “Compared to the younger generation who are born with all these technologies, my adaptability makes me feel younger”. On the other side of the globe, one female respondent in India cited tech as making her feel like she “can do anything with it which any youngster can do,” and one Chinese male respondent said: “It helps me catch up with the times – not only gaining more knowledge, but also feel that I’m on-trend; I feel younger”.
The research generally revealed that many older generations think using technology helps them to connect better with younger people as well as feel livelier and more knowledgeable. This is especially evident when it comes to the role smart devices (from PCs, tablets to smart home assistants and more) play in terms of relationships with family and friends. When asked to compare technology today to those of 20 years ago for giving them the ability to feel connected to what is going on in the lives of the people they care about, 65 percent answered it’s “getting better”. While 75% also said technology is improving their ability to stay in touch with family and friends who live far away.
The global research also revealed that tech is helping people when it comes to mental health and wellbeing, offering emotional gains, particularly in parents. Over three-quarters (78%) of working parents stated the ever-connected nature of technology helps them feel more emotionally connected to their children, even when they are away from home. An even larger portion (83%) of working parents agreed that emerging technologies are making it easier for them to feel confident that their kids are safe and secure while they are at work.
Over two-thirds (67%) of respondents in the survey stated they were optimistic about the future of technology and the role tech can play in our lives and society, especially in wellbeing, with 67% believing devices are currently having a positive impact on the ability to improve their overall health. And that’s hardly surprising, considering 84% also said tech has empowered them to make improvements in their lives overall.
Take for instance how one respondent, a 51-year-old woman from the US, highlighted how science is using technology to do great things for amputees, and enabling those suffering from mental illness to better connect with people from all over the world. “I think that the medical breakthroughs we’ve had are a tremendous statement on how we can have a positive relationship with technology,” she said.
The recognition that tech is helping to improve the quality of life could also be a result of the time it tends to save people. Half of respondents across all markets (50%) feel their smart devices save them 30 minutes or more a day by helping them do something faster or more efficiently. Similarly, over half (57%) agreed smart devices, such as computers and smart home devices like smart displays and smart clocks, are making them more productive and efficient, the highest perceptions of which were seen in China at 82% and India at 81%.
In terms of personal health, 36% of respondents said smart devices have made it easier for them to access health care providers and make doctor’s appointments, and a further 39% of those under 60 years of age stated modern tech makes it easier for seniors to contact emergency services.
A 23-year-old woman from India, for example, expressed her belief that the technological advancement of medical science is helping people better fight diseases and potentially cure them. “Lives of people are better off nowadays because they know ways of curing such health hazards,” she said. “Through technology, increasing the life span of an individual is very much possible.”
Psychologist and founder of Digital Nutrition, Jocelyn Brewer, said: “Keeping up with advancements in technology can feel like a full-time job, but it can have positive impacts on people’s sense of themselves and their age. While older people are stereotyped as being techno-phobic or inept at staying on-trend, this research points to the fact that maintaining currency in the digital space helps people feel more youthful, more connected to young people and youth culture, which in turn is a social currency for feeling valued and a sense of belonging or in ‘the know’.
“It’s this tech knowledge that drives the perception of feeling younger, without having to revisit the angst of our adolescence!
“Staying connected to the people we care about is a wonderful feature of technology. And while it is no replacement for face-to-face connection, it is a valuable supplement to communication for those who might be geographically divided. Parents can manage a range of responsibilities and provide increasing appropriate autonomy to teenagers through a variety of communication tools, reminders and systems that can help take the struggle out of the daily juggle.”
Dilip Bhatia, Vice President of User and Customer Experience, Lenovo, said: “There is a growing relationship between innovation and wellbeing as smart technologies are not only helping people globally to stay more connected but aiding wellbeing in the form of compassion and empathy by building better connections between them.”
“Technology has a transformational ability to unite people across generations and walks of life around the world, with the potential to help them to live healthier and more fulfilling lives. At Lenovo, we passionately believe in creating smarter technology for all, which is why we focus on making our technology accessible, blending into the everyday lives for the benefit of more people.”
Advanced traffic management tech market hits $1bn
A new report from Navigant Research analyzes the ongoing transformation occurring in the traffic management industry, providing global market forecasts, segmented by region and technology, through 2028.
Advanced traffic management systems (ATMSs) such as adaptive traffic control (ATC) are enabling greater efficiencies in the traffic management ecosystem and can help integrate the expected growth in vehicle populations without overwhelming existing infrastructure. ATMSs are also enabling the development of smart intersections, which are emerging as one of the most important data-driven backbones needed for solving core city challenges. Click to tweet: According to a new report from Navigant Research, the global market for advanced traffic management will be worth more than $1.1 billion in 2019. Annual revenue is expected to grow to nearly $3.8 billion by 2028, representing a compound annual growth rate (CAGR) of 14.2%.
“The global advanced traffic management market is expected to more than triple by 2028,” says Ryan Citron, senior research analyst with Navigant Research. “Over the next 10 years, the market is expected to achieve gradual but accelerating growth as cities prioritize reducing traffic congestion and greenhouse gas emissions, make improvements in safety and livability, and integrate ATMSs with other smart city initiatives (e.g., smart street lighting).”
Currently, cities vary in their level of maturity in using ATMSs. Collecting traffic and vehicle detection data is often the first step toward advanced traffic management. Then, in-depth traffic analytics enable traffic managers to develop mitigation strategies and make operational improvements to existing traffic signal timing systems. In cities with mature traffic management solutions, ATC technologies enable traffic signals to adjust based on real-time traffic conditions, traffic data is sent from traffic lights to connected vehicles, inter-agency data sharing is on the rise, and transport platforms are used to manage mobility ecosystems.
The report, Advanced Traffic Management for Smart Cities, analyzes the ongoing transformation occurring in the traffic management industry. The study focuses on ATC, traffic analytics, artificial intelligence, vehicle-to-infrastructure communications, and vehicle detection technologies. Global market forecasts, segmented by region and technology, extend through 2028. This report also explores regional trends in advanced traffic management strategy and highlights city case studies where innovative projects are being deployed.
