Roadtripping through Africa in a solar-powered car

Published

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.

Mars Rover

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.

Power pumps

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.

Cisco Security Connector

With all the malware, viruses and trojans doing the rounds, it is difficult for users and enterprises to ensure that they don’t become targets. Cisco, in collaboration with Apple, has brought out its Cisco Security Connector to protect users. The app is designed to give enterprises and users overall visibility and control over their network activity on iOS devices. It does this by ensuring compliance of mobile users and their enterprise-owned iOS devices during incident investigations, by identifying what happened, who it affected, and the risk of the exposure. It also protects iPhone and iPad users from accessing malicious sites on the Internet, whether on the corporate network, public Wi-Fi, or cellular networks. In turn, it prevents any viruses from entering a company’s network.

Platform: iPhones and iPads running iOS 11.3 or later

Expect to pay: A free download

Stockists: Visit the Apple App Store for downloading instructions.

 

Diski Skills

The Goethe-Institut, in co-operation with augmented reality specialists Something Else Design Agency, has created a new card game which celebrates South African freestyle football culture, and brings it alive through augmented reality. Diski Skills is quick card game, set in a South African street football scenario, showing popular tricks such as the Shibobo, Tsamaya or Scara Turn. Each trick is rated in categories of attack, defence and swag – one wins the game by challenging an opponent strategically with the trick at hand. Through augmented reality, the cards come alive. Move a smartphone over a card and watch as the trick appears on the screen in a slow motion video. An educational value is added as players can study the tricks and learn more about the idea behind it.

 

The game will be launched on 27 October 2018 at the Goethe-Institut.

Namola

With  recent news of kidnappings on the rise, a lot more thought is going into keeping children safe. Would your child know what to do in an emergency? Have you actually asked them?

Namola, supported by Dialdirect Insurance, is a free mobile safety app. Namola’s simple interface makes it an ideal way for children to learn how to get help in an emergency. All they need to do is activate the app and push a button to get help that they need, even when their parents are not around.

Parents need to install the app on their child’s phone, hold down the request assistance button, program emergency numbers that will automatically be dialled when the emergency button is pushed, and teach their children how and when to use the app.

Platform: Android and iOS

Expect to pay: A free download.

Stockists: Visit the store linked to your device.

 

Exhibid

Exhibid could be thought of as Tinder, but for for art lovers. The interface looks very similar to the popular mobile dating app, in that users swipe left for a painting that doesn’t appeal to them, or swipe right for something they like. Once an art piece is liked by swiping right, one can start bidding or make an offer on it. The bid is automatically sent to the artist. Should he or she accept the offer, the buyer makes a payment through the app’s secure payment gateway and the two are put in contact to make arrangements for delivery.

Platform: Android and iOS

Expect to pay: A free download.

New kind of business school

At a recent meeting, ALLON RAIZ, founder and CEO of Raizcorp, realised that in order for today’s youth to become entrepreneurs, teachers, the curriculum and the parents need continually expose them to entrepreneurial thinking from a young age.

Published

on

Several years ago, I found myself in a meeting with my business partner and two of my staff members. In front of us was a client who was sharing some of the frustrations in his business. At the end of the meeting, my partner and I were extremely excited about the prospect of two massive opportunities we had both independently identified while listening to the client. My two staff members, on the other hand, completely missed them. This led me to wonder what it was in my own and my partner’s backgrounds that allowed us to so easily spot opportunities while my two staff members remained oblivious … I realised that the difference was that my partner and I both had an early exposure to entrepreneurship while they didn’t.

Not long afterwards, I was delivering a lecture about how Raizcorp grows and develops small businesses at Oxford University’s Said Business School in my role as their Entrepreneur-in-Residence. I mentioned the above incident and spoke about my intention of going into children’s education with a view to providing an entrepreneurial perspective.

One of the professors in attendance asked me if I’d ever heard of a piece of research by Henrich R Greve called Who wants to be an entrepreneur? The deviant roots of entrepreneurship. It’s a pretty unfortunate title but a fascinating piece of research nonetheless. It highlights how certain contexts in childhood result in a much a higher probability of becoming an entrepreneur. For example, kids who participate in solo sports such as tennis or athletics are more likely to become entrepreneurs than children who play team sports like soccer and cricket. Conversely, your mother’s participation in the parent-teacher association has a negative correlation to you becoming an entrepreneur. I spent the rest of the afternoon in the professor’s office discussing other research papers that unequivocally proved that context during your childhood has a massive influence on whether or not you will follow the entrepreneurial route.

Another member of the lecture audience was a double-PhD from the USA who was completing her MBA at Oxford. After the lecture, she approached me and volunteered to help build a framework to incorporate entrepreneurship in the school curriculum without interfering with the formal requirements of the CAPS curriculum.

She spent nine months in South Africa working with me to build out a practical framework. The next phase of the plan was to find the right school at which to embark upon this journey. In December 2015, Raizcorp purchased Radley Private School and we began our entrepreneurial education adventure in earnest in 2016.

At the centre of the Radley philosophy is that the school (the physical building), the teachers, the curriculum and the parents are the “marinade” in which the kids need to soak in order to be continuously exposed to entrepreneurial thinking from a young age. The aim was that if, in future, the kids found themselves sitting in a boardroom with me and my partner, they too would be able to identify the opportunities that we did.

A big shift this year has been the launch of our Entrepreneurial Educator Guide (EEG) programme where we have been training our Radley teachers (whom we call guides) to understand entrepreneurship, business language, business concepts, financial documents and the like. (The EEG training makes use of Raizcorp’s internationally accredited entrepreneurial learning and guiding methodologies.) We have also employed a full-time staff member to ensure that these concepts are imbedded into all lesson plans and classroom activities.

Through my network at Raizcorp, I have been pleasantly surprised by the massive support we’re receiving from prominent entrepreneurs and businesses who want to participate in our Radley Exposure programme, where we take our kids of all ages on visits to different types of businesses so they can understand the difference between retail, wholesale, manufacturing, logistics and so on. Prominent businesspeople have put up their hands to come to the school and tell their stories of hard work, resilience and perseverance. This ties in beautifully with the 17 entrepreneurial concepts that we are instilling into our Radley learners (such as opposite eyes, lateral thinking and opposable mind), while never compromising on our quality academic offering.

As parents, we’ve all heard the terrible statistics about the probability of our kids finding jobs in the future. At Radley, we’re working hard to ensure that our kids have a legitimate and lucrative alternative to finding traditional employment and that is to become an entrepreneur. Radley is all about producing job creators and not job seekers!
