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.”

Prof. Dingie Janse van Rensburg promoted to Outstanding Professor
2007-11-19

The University of the Free State (UFS) is pleased to announce that Prof. Dingie Janse van Rensburg, Director of the Centre for Health Systems Research and Development has been promoted to Outstanding Professor.

In 1991 the Executive Committee of the Council introduced the category of Outstanding Professor to give recognition to a small group of outstanding academics. Not many academics at the UFS received this status since then.

Prof. Janse van Rensburg has been working at the UFS for 37 years and played a big role in establishing a culture of scientific publication among young and upcoming researchers.

Prof. Janse van Rensburg enjoys extensive national and international recognition as researcher and research manager. He delivered various national and international papers and is involved in a variety of international research projects – some of which were initiated by him. He succeeded in involving a variety of foreign researchers in long term research projects.

In 1993 he established an entrepreneurial research and development centre, which he has sustained for more than 13 years. The centre enjoys recognition nationally as well as internationally as well as credibility in the eyes of the international donor community, within government’s health sphere as well as in peer academic circles.

Prof. Janse van Rensburg has for several years been a grant holder of both the National Research Foundation and the Medical Research Council for research projects on Tuberculosis and HIV/Aids.

During his career at the UFS Prof. Janse van Rensburg received several merit awards and commendations from the UFS and other institutions. These include the Stals Prize in 1993 from the Suid-Afrikaanse Akademie vir Wetenskap en Kuns, a Council Medal from the UFS in 2003, the UFS Centenary Medal in 2004, an award from the Department of Health in 2004 for excellence and continued support of this department, a promotion to Senior Professor from the UFS in 2005 and the Free State Premier’s Excellence Award Gold category in 2006 for excellence in research and development.
