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.”

UFS to investigate implementation of quality-monitoring system for SA food industry

The University of the Free State (UFS) will be investigating the implementation of a quality-monitoring service for the South African food industry. 

This was decided during a workshop to discuss the external quality monitoring in the edible oil industry of South Africa, which was recently held at the UFS.

Major role players in the fast-food sector like Nando's, Spur, Captain
Dorego's, King Pie Holdings, Black Steer Holdings, etc and various oil
distributors like Felda Bridge Africa, Refill Oils, PSS Oils and Ilanga Oils attended
the workshop. Also present was Mrs Ina Wilken, Chairperson of the South African National Consumer Union (SANCU) and key-note speaker of this workshop. She represented the consumer.  

These role players all pledged their support to the implementation of this quality- monitoring system for the whole food industry. 

The decision to implement this system follows the various malpractices reported in the press and on TV concerning food adulteration (eg the recent Sudan Red Scare), misrepresentation (eg olive oil scandal exposed in 2001) and the misuse of edible frying oils by the fast-food sector. 

“One of the basic rights of consumers is the right to safe food. Consumers must be protected against foods and food production processes which are hazardous to their health. Sufficient guarantee of the safety of all food products and food production processes should be implemented. It does not help to have adequate food standards and legislation and there is no manpower to do the necessary investigation or monitoring,” said Mrs Wilken.

The South African Fryer Oil Initiative (SAFOI), under the auspices of the UFS Department of Microbial, Biochemical and Food Biotechnology, currently monitors edible oils in the food industry and makes a seal of quality available to food distributors.

“Last week’s decision to implement the quality-monitoring system implies that we will now be involving also other departments in the UFS Faculty of Natural and Agricultural Sciences who are involved in various aspects of the food chain in an endeavor to implement this quality monitoring system,” said Prof Herman van Schalkwyk, Dean:  Faculty of Natural and Agricultural Sciences at the UFS and one of the main speakers at the workshop.

Prof van Schalkwyk said that the main aim of such a system will be to improve the competitiveness of the South African food industry.  “It is clear that the role players attending the workshop are serious about consumer service and that they agree that fraudulent practice should be monitored and corrected as far as possible.  Although some of the food outlets have the capacity to monitor the quality of their food, it may not seem to the consumer that this is an objective process.  The proposed external monitoring system would counteract this perception amongst consumers,” said Prof van Schalkwyk.

The workshop was also attended by representatives from SAFOI and Agri Inspec, a forensic investigation company collaborating with inter-state and government structures to combat fraud and international trade irregularities.

Agri Inspec has been working closely with SAFOI for a number of years to test the content of edible oils and fats.  “Extensive monitoring and control actions have been executed in the edible oil industry during the past four years to ensure that the content and labeling of oil products are correct.  Four years ago almost 90% of the samples taken indicated that the content differed from what is indicated on the label.  This has changed and the test results currently show that 90% of the products tested are in order. However, to maintain this quality standard, it is necessary that quality monitoring and educational campaigns are continuously performed,” said Mr Joe Hanekom, Managing Director of Agri Inspec. 

“The seal of quality presented by SAFOI should also be extended to include all the smaller oil containers used by households,” Mrs Wilken said.

The SAFOI seal of quality is currently displayed mainly on some oil brands packed in bigger 20 liter containers, which include sunflower oil, cottonseed oil, palm oil etc which are used by restaurants and fast food outlets.  “Any oil type is eligible to display the seal when meeting certain standards of authenticity.  In order to display the seal, the distributor must send a sample of each oil batch they receive from the manufacturer to SAFOI for testing for authenticity, ie that the container’s content matches the oil type described on the label. This is again double checked by Agri Inspec, which also draws samples countrywide from these certified brands from the end-user (restaurant or fast food outlets). If in breach, the seal must be removed from the faulty containers,” said Prof Lodewyk Kock, Head of SAFOI.

“It should however be taken into account that oils without a seal of quality from the UFS can still be of high quality and authentic. Other external laboratories equipped to perform effective authenticity tests may also be used in this respect,” said Prof Kock.

“It is also important to realise that any oil type of quality such as sunflower oil, cottonseed oil, palm oil etc can be used with great success in well controlled frying processes,” he said.

Further discussions will also be held with the Department of Health, the SA National Consumer Union and Agri Inspec to determine priority areas and to develop the most effective low-cost monitoring system.
