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.

Well-established root system important for sustainable production in semi-arid grasslands

The importance of a well-established root system for sustainable production in the semi-arid grasslands cannot be over-emphasised.

A study of Prof Hennie Snyman from the Department of Animal and Wildlife and Grassland Sciences at the University of the Free State is of the few studies in which soil-water instead of rainfall has been used to estimate above- and below-ground production of semi-arid grasslands. “In the past, plant ecological studies have concentrated largely on above-ground parts of the grassland ecosystem with less emphasis on root growth. This study is, therefore, one of the few done on root dynamics in drier areas,” said Prof Snyman.

The longevity of grass seeds in the soil seed bank is another aspect that is being investigated at present. This information could provide guidelines in grassland restoration.

“Understanding changes in the hydrological characteristics of grassland ecosystems with degradation is essential when making grassland management decisions in arid and semi-arid areas to ensure sustainable animal production. The impact of grassland degradation on productivity, root production, root/shoot ratios, and water-use efficiency has been quantified for the semi-arid grasslands over the last 35 years. Because of the great impact of sustainable management guidelines on land users, this study will be continuing for many years,” said Prof Snyman.

Water-use efficiency (WUE) is defined as the quantity of above- and/or below-ground plant produced over a given period of time per unit of water evapotranspired. Sampling is done from grassland artificially maintained in three different grassland conditions: good, moderate, and poor.

As much as 86, 89 and 94% of the roots for grasslands in good, moderate and poor conditions respectively occur at a depth of less than 300 mm. Root mass is strongly seasonal with the most active growth taking place during March and April. Root mass appears to be greater than above-ground production for these semi-arid areas, with an increase in roots in relation to above-ground production with grassland degradation. The mean monthly root/shoot ratios for grasslands in good, moderate, and poor conditions are 1.16, 1.11, and 1.37 respectively. Grassland degradation lowered above- and below-ground plant production significantly as well as water-use efficiency. The mean WUE (root production included) was 4.79, 3.54 and 2.47 kg ha -1 mm -1 for grasslands in good, moderate, and poor conditions respectively.

These water-use efficiency observations are among the few that also include root production in their calculations.
