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.”

A great honour was bestowed on a researcher at the University of the Free State (UFS) when he was invited to the preview of the documentary film, Last of the Longnecks. Dr Francois Deacon, lecturer and researcher in the Department of Animal, Wildlife and Grassland Sciences at the UFS, who also has a role in the film, attended the preview at the Carnegie Institution for Science’s Smithsonian National Museum in Washington DC, in the US, in March this year. The preview formed part of the DC Environmental Film Festival.

The Environmental Film Festival in the US capital is the world’s leading showcase of films with an environmental theme and which aims to improve the public’s understanding of the environment through the power of film. During the festival, the largest such festival in the US, more than 150 films were shown to an audience of 30 000 plus. 

Dr Deacon was invited by the producer of Last of the Longnecks to be part of a panel handling a question-and-answer-session about the film directly after the show. He described it as the greatest moment of his life. 

Role in the film Last of the Longnecks

“My role in the film was as the researcher studying giraffes in their natural habitat in order to understand them better, so that we may better protect them, and be able to provide better education on the problem in Africa,” says Dr Deacon. 

“Together with Prof Nico Smit, also from the UFS Department of Animal, Wildlife and Grassland Sciences, Hennie Butler from the Department of Zoology, and Martin Haupt from Africa Wildlife Tracking, we were the first researchers in the world to equip giraffes with GPS collars and to conduct research on this initiative,” he says. This ground-breaking research has attracted international media attention to Dr Deacon and Prof Smit. 

“Satellite tracking is proving to be extremely valuable in the wildlife environment. The unit is based on a mobile global two-way communication platform, utilising two-way data satellite communication, complete with GPS systems.

“It allows us to track animals day and night, while we monitor their movements remotely from a computer over a period of a few years. These systems make the efficient control and monitoring of wildlife in all weather conditions and in near-to-real time possible. We can even communicate with the animals, calling up their positions or changing the tracking schedules,” says Dr Deacon.

The collars, which have been designed to follow giraffes, enable researchers to obtain and apply highly accurate data in order to conduct research. Data can be analysed to determine territory, distribution or habitat preference for any particular species.

Over a period of three years (2014-2016), the Last of the Longnecks team from Iniosante LLC captured on film how Dr Deacon and his team used the GPS collars in Africa to collect data and conduct research on the animals.

“With our research, which aims to understand why giraffes are becoming extinct in Africa, we are looking at the animal in its habitat but not only the animal on its own. If the habitat of these animals is lost, they will be lost as well. Therefore, our focus is on conservation and better understanding the habitat. The giraffe is only a tool to better understand the habitat problem,” says Dr Deacon. 

Since the beginning of his research Dr Deacon and his team have had six new collar designs, with animals in four different reserves being equipped with the collars. The collars use the best technology available in the world and make it possible to determine how giraffes communicate over long distances, and how their sleep patterns function. Physiological and biological focus is placed on the giraffe’s stress levels, natural hormone cycles, and milk quality in cows.

Experience at the film festival

“Absolutely amazing. Totally beyond our frame of reference as South Africans.” This is how Dr Deacon describes his experience of the three days in Washington DC during the film festival.

“It was an absolute honour to be part of the global preview of the film and to be able to work with Ashley Davison, the director of the film, and his team. I am just a rural farm boy who dreams big, and now this dream is known worldwide!” he says. 

The film, which will be launched in April, will be screened in South Africa on the National Geographic channel in May 2017. Meanwhile, the film will also be shown at eight other film festivals in the US. 

Work will start on a follow-up documentary in October and Dr Deacon is excited about the prospect. A mobile X-ray machine will be available from October. Internal sonars could also be performed on each of the animals. Researchers from around the world will form part of the team which will be led and co-ordinated by Dr Deacon and his co-workers at the UFS.
