Eco Vehicle Race 2024
This year's Eco-Vehicle Skills Programme saw remarkable participation. A total of 148 students completed the programme successfully.

For the past seven years, the University of the Free State’s (UFS) Kovsie ACT has proudly hosted the successful Eco-Vehicle Race. This event has grown into a major highlight, thanks to the significant support from MerSETA (Manufacturing, Engineering and Related Services), which has enabled the development of a comprehensive skills programme focused on sustainable energy and eco-vehicle technology.

In 2020, MerSETA's funding allowed Kovsie ACT to create a detailed skills initiative culminating in the exciting 2021 eco-vehicle race. Over nine months, 150 students received extensive training in eco-vehicle technology. This programme provided students with both theoretical knowledge and practical experience, preparing them not only for the competition but also for real-world applications of sustainable energy solutions.

Dr WP Wahl, Director of Student Life, emphasises the value of this initiative, saying, “This effort provides students with a set of skills that will help position them in the labour market. They are equipped with basic knowledge and abilities in sustainable energy, enabling them not only to compete in the eco-vehicle race but also to comprehend the inner workings of the vehicle.”

CUT Team 4: Overall winner of Kovsie ACT’s Eco-Vehicle Race 2024

According to Teddy Sibiya from the Kovsie ACT office, this year's Eco-Vehicle Skills Programme saw remarkable participation and achievements. A total of 148 students - 118 from the UFS and 30 from the Central University of Technology (CUT) - completed the programme successfully. Additionally, 10 engineering mediators completed the Mediated Learning Experience course, providing mentorship essential to the students.

In the 2024 Kovsie ACT Eco-Vehicle Race, CUT Team 4 emerged as the overall winner. Kovsie Q secured second place and East College took third place. North College won the Spirit Cup and was announced as the pitstop winner alongside East College.

In the Obstacle Race, which tested teams' control over their cars through various challenges, CUT Team 4 claimed the winning title. They also came in first place in the Endurance Race, where the objective was to complete as many laps as possible using the least amount of energy in 45 minutes.

The race took place at the UFS’s Bloemfontein Campus on Akademie Avenue, next to the George du Toit Administration Building, with spectators watching from the Red Square parking area.

Eco-Vehicle Sustainable Skills Programme 2.0 introduced

Sibiya announced the next phase of the journey - the Eco-Vehicle Sustainable Skills Programme 2.0. “With continued support from MerSETA, we have expanded our partnerships to include Nelson Mandela University and will continue to involve students from the Central University of Technology.”

“In the next phase, the focus is on developing a new eco-vehicle prototype and creating an advanced skills programme around it,” adds Sibiya. “We aim to debut and race this new eco-vehicle by 2025, continuing our commitment to innovation and sustainable energy education.”

Dr Wahl elaborates, “Students will be taught the same skills, but the learning experience will be deepened. The skills programme consists of five cycles. In cycle one, the students build a race car on a small scale that includes a charging station and a small solar panel. In cycle two, students learn to programme the small-scale racing car from their cell phones or laptops. In cycles three and four, they build the larger race cars with battery packs and solar panels. All of these come together in cycle five during the Eco-Vehicle race when the energy conservation of the cars is tested.

Support from sponsors

Several sponsors were involved in this year’s Eco-Vehicle Race. OFS Fire supported the race with equipment and certified training for all the participating students. Several of the teams also secured sponsorships: East College from Deluxe Grills, South Campus from SA Truck Bodies, West College from Mpeki Tsh Trading and Project, and the CUT Teams from the South African Institute of Electrical Engineers (SAIEE). Haval also exhibited a car at the event.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
