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.

Smash hits the
Super Smash Bros. delivers what the fans wanted in the latest “Ultimate” instalment, writes BRYAN TURNER.
Super Smash Bros. Ultimate, the latest addition to the popular Nintendo Smash series, has landed on the Nintendo Switch with a bang, selling 5-million copies in the first week of its release. The game has been long-anticipated since the console’s release, as many fans consider
It features 74 playable fighters, 108 stages, almost 1300 Spirit characters to collect while playing, and a single-player Adventure mode that took about three days (or 28 hours) of gameplay to complete. The game offers far more gameplay than its predecessors, making it the Smash game that gives its players the best bang for their buck.
For those new to the game, the goal is to fight opponents and build up their damage score (draining their health) to knock them off the stage eventually. This makes the game seem chaotic, as many players jump around the platforms as if they were on quicksand, in order to avoid being hit by the other players.
It also services two kinds of players: the competitive and the casual.
Competitive players can be matched on the online service by skill ranking to enjoy playing with similarly high-skilled opponents. This is especially important in e-sports training for the game, and for players wanting to master combos against other human players. The casual gamer is also catered for, with eight-player chaos and button-mashing to see who comes out luckiest. This segment is also important for those wanting to learn how to play.
Training mode is also a place to go for those learning to play. It offers “CPU” players that are graded by intensity to train as a single player to learn a character’s moves, combos and general fighting style. More challenging CPU players can also be used by competitive players to train when there isn’t a Wi-Fi connection available.
Direct Play features in this game, allowing two players with two Switch consoles to play against each other over a direct connection – no Wi-Fi needed. This is especially useful to those who want to have a social gaming element on the go, similar to that of the cable connector of the Gameboy.

Win Funko Fortnite in Vinyl
Gadget and Gammatek have nine Funko Fortnite figurines to give away.
A Funko Pop figurine based on a character set is indicative of reaching the heights of pop culture. It is no surprise, then, that the world’s biggest online game, Fortnite, has its own line of Funko Pop figurines. The Funkos are modeled on the characters in game, including Drift, Ragnarok, Dark Vanguard, Volar, Tracera Ops, and Sparkle Specialist.
Now, local Funko distributor Gammatek has released the Fortnite figurines in South Africa. To celebrate, Gadget and Gammatek are giving away a set of three Funko Fortnite figurines to each of three readers (9 figurines in total). To enter,
