UFS Sasol Solar car
Team UFS, which has entered its solar-powered vehicle, Lengau (meaning Cheetah in Sesotho), will compete against more than 11 other teams, both local and international. Pictured here is the entire team during one of the road tests at Brandkop in Bloemfontein.

It is almost three years after Team UFS first decided to put a solar-powered vehicle on the road. Within a few days, this dream of participating in the international Sasol Solar Challenge will become a reality when they depart from Carnival City in Johannesburg on 9 September 2022.

For the challenge, the team of ten members will stop at six points between the departure point and the V&A Waterfront in Cape Town, where they will arrive on 16 September 2022.

Completing the estimated distance of 2 500 km

“The team that finishes with the greatest distance covered within the allotted time, will win the challenge,” says Dr Hendrik van Heerden from the UFS Department of Physics and project manager of Team UFS. 

The UFS, which has entered its solar-powered vehicle, Lengau (meaning Cheetah in Sesotho), will compete against more than 11 other teams, both local and international.

Dr Van Heerden’s two main objectives in entering the challenge, are to build a solar-powered vehicle robust enough to complete the estimated distance of 2 500 km during the 2022 Sasol Solar Challenge. Furthermore, he aims to establish capacity in the students and staff through acquired practical knowledge on the management, design, construction, and actual racing of solar-powered vehicles, which is to form the basis for participation in future projects and event competitions. 

Bringing together expertise from the UFS Departments of Physics, Engineering Sciences, Computer Sciences and Informatics, Electronics and Instrumentation, and Geography, the team of 23 started with the construction of their vehicle on 18 October 2021. 

Just over 10 months later and the car is fully functional, already passed a few road tests, and the crew is ready for the big challenge ahead.

The three drivers, Albert Dreyer, Monica van der Walt, Denver de Koker, together with back-up driver Lukas Erasmus, will travel on public roads via a predefined route over eight days, driving every day between 07:30 and 17:00. The aluminium-frame vehicle will weigh up to 370 kg, including the frame, the five solar panels, and the driver, and can reach a maximum speed of 60 km per hour (they aim to average 45 km/hour). 

According to the Sasol Solar Challenge rules and regulations, no driver is allowed to drive for longer than two hours. The capacity of the batteries and the availability of sun will determine how often the drivers will need to stop to recharge the solar batteries. 

Popularising electric vehicle technologies

This is the first time that Team UFS will be participating in the Sasol Solar Challenge. A guardedly optimistic Dr Van Heerden says their goal is to complete the full distance without breakages, and to accumulate as much knowledge and information as possible. With the next Sasol Solar Challenge in two years’ time, they plan to enter again. 

“Our long-term aim is to continually improve on the design, technology, science, and project implementation to participate in events and challenges around ‘green’ energy and relevant technologies. An additional aim is the popularisation of electric vehicle (EV) technologies through outreach programmes,” says Dr Van Heerden. 

Prof Koos Terblans, Head of the Department of Physics, says one of the key benefits of this project was that the group, consisting of personnel and students from different departments, learned to work together as one team. “Together, they worked and made plans to collect and apply the maximum amount of energy. Looking at the bigger picture, they are solving a worldwide problem, that of harvesting and applying energy. I am very excited that they have come this far; this is a first for the university.”

Mafuma aims at elusive tournament victory with Junior Springboks

He has never won a rugby tournament, so Mosolwa Mafuma has only one goal: to win the Junior World Cup as Junior Springbok in England.

Even though the 20-year-old Shimlas wing has achieved success, and it is pleasing to excel individually, he believes it is more satisfying when his team triumphs. According to Mafuma, who could just as well be an athletics star, he wants to help the South African U20 team take a different approach.

He and the prop Kwenzo Blose are players from the University of the Free State who will represent the Junior Springboks from 7 to 25 June 2016 in Manchester. The team will play the first of three group matches on 7 June 2016 against Japan in the Academy Stadium.

New approach for SA U20 team
Mafuma, who was Player of the Tournament in his first Varsity Cup in 2016, says the Junior Springboks are well prepared. “We have the skills, and the structures at the Junior Springboks are different than before. There is not just one game plan like playing with big guys. We want to try new things and have a different approach.”

It is with this team that he wishes to achieve something. “It is one thing to be able to say that you are the Player of a Tournament, but your team did not win. I have not won something at school (with St. Benedict’s Boys College in Johannesburg) or this year with the Shimlas.”

Speedster on athletics track
The speedster is one of only a few rugby players who also have a profile on the IAAF website. His fastest time in the 100 m is 10.37 seconds (a national U17 record) and 20.37 s in the 200 m.

In high school, this first-year Psychology student played rugby during winter and took part in athletics during summer. Only at the end of Grade 11 did he started focusing on rugby. “I was more of an athlete than a rugby player,” he says.

It is no coincidence that the nickname he acquired due to his speed, is Dash. His other nickname, Senkie (derived from the Afrikaans word ‘seuntjie’) he received as a child from his parents because he was such a small child.
