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.”

Researchers international leaders in satellite tracking in the wildlife environment
2015-05-29

 

Ground-breaking research has attracted international media attention to Francois Deacon, lecturer and researcher in the Department Animal, Wildlife and Grassland Sciences at the UFS, and Prof Nico Smit, from the same department. They are the first researchers in the world to equip giraffes with GPS collars, and to conduct research on this initiative. Recently, they have been joined by Hennie Butler from the Department of Zoology as well as Free State Nature Conservation to further this research.

“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 the computer. These systems make possible the efficient control and monitoring of wildlife in all weather conditions and in near-to-real time. We can even communicate with the animals, calling up their positions or changing the tracking schedules.

“The satellite collar allows us to use the extremely accurate data to conduct research with the best technology available. The volume of data received allows us to publish the data in scientific journals and research-related articles.  

“Scientific institutions and the public sector have both shown great interest in satellite tracking, which opens up new ground for scientific research for this university. Data management can be done, using Africa Wildlife Tracking (AWT) equipment where we can access our data personally, store it, and make visual presentations. The AWT system and software architecture provide the researcher with asset tracking, GPS location reports, geo-fencing, highly-detailed custom mapping, history reports and playback, polling on demand, history plotting on maps, and a range of reporting types and functions,” Francois said.

Data can be analysed to determine home range, dispersal, or habitat preference for any specific species.

Francois has been involved in multiple research projects over the last 12 years on wildlife species and domesticated animals, including the collaring of species such as Black-backed Jackal, Caracal, African Wild Dog, Hyena, Lion, Cheetah, Cattle, Kudu, Giraffe, and Black Rhino: “Giraffe definitely being the most challenging of all,” he said.

In 2010, he started working on his PhD, entitled The spatial ecology, habitat preferences and diet selection of giraffe (Giraffa camelopardalis giraffa) in the Kalahari region of South Africa.

 

Since then, his work has resulted not only in more research work (supervising four Masters students) but also in a number of national and international projects. These include work in the:

  • Kalahari region (e.g. Khamab Nature Reserve and Kgalagadi Transfrontier Park)
  • Kuruman region (Collared 18 cattle to identify spatial patterns in relation to the qualities of vegetation and soil-types available. This project took place in collaboration with Born University in Germany)
  • Woodland Hills Wildlife Estate and Kolomella Iron Ore – ecological monitoring
  • A number of Free State nature reserves (e.g. Distribution of herbivores (kudu and giraffe) and predators (camera traps)

Francois is also involved with species breeding programmes and management (giraffe, buffalo, sable, roan, and rhino) in Korrannaberg, Rustenburg, Hertzogville, Douglas, and Bethlehem as well as animal and ecological monitoring in Kolomella and Beesthoek iron ore.

Besides the collaring of giraffes, Francois and his colleagues are involved in national projects, where they collect milk from lactating giraffes and DNA material, blood samples, and ecto/endo parasites from giraffes in Southern Africa.

With international projects, Francois is working to collect DNA material for the classification of the nine sub-species of giraffe in Africa. He is also involved in projects focusing on the spatial ecology and adaptation of giraffe in Uganda (Murchison Falls), and to save the last 30 giraffe in the DRC- Garamba National Park.

This project has attracted a good deal of international interest. In June 2014, a US film crew (freelancing for Discovery Channel) filmed a documentary on Francois’ research (trailer of documentary). Early in 2015, a second crew, filming for National Geographic, also visited Francois to document his work.
