East College - Eco Vehicles Team
Overall winners of the 2022 Eco-vehicle race, East College, hard at work to get their car ready for the race held at the Odeion parking lot on the Bloemfontein Campus.

For the first time, the University of the Free State’s 2022 Eco-vehicle race – held on the Bloemfontein Campus on 14 May 2022 – had students from all three campuses participating in the programme and race; a cup was awarded to the college with the best support.

Although the annual event did take place in 2021, only team members were allowed access to campus due to the COVID-19 pandemic and lockdown regulations, and therefore the race was streamed live. 

Karen Scheepers, Assistant Director: Student Life, said: “To have the students back on campus supporting their teams was incredible; this event will become bigger and better every year.”

With the Eco-vehicle race project, the UFS aims to use an innovative skills development approach that will enable students to develop basic knowledge and skills on sustainable energy.

This year, 130 undergraduate students enrolled for this co-curricular skills programme that runs for nine months and culminates in the Eco-vehicle race. A total of eight teams competed in the energy efficiency race, speed race, obstacle course race, and the main event – the endurance race. For the first time in the main event, the teams raced against each other for 18 laps. 

The winners of this year’s event were Central College (Akasia, Karee, Kagiso, Soetdoring, and Wag-’n-Bietjie residences) for Spirit Cup, South Campus took home the Pit Stop, North College won the Smart Lap, and South College won the Endurance Race. The overall winners of the Eco-vehicle race were East College (Legatum residence). 

The driver for East College, Lebakeng Motlotlo, said: “Even though I have always been part of the KovsieACT Committee in my residence, seeing that the focus this year was more on energy saving and saving resources, it pushed me to participate.”

Motlotlo believes the practice he and his team went through worked for them, as they were able to practise “how to turn, slow down around corners, and save energy”. 

“Our team was very dedicated and knew how to improvise when faced with challenges. As a small residence and most of us living off campus, the race taught us the importance of teamwork.” 

Motlotlo believes “initiatives such as the Eco-vehicle race are important, as we learn other skills outside of lectures, which we sometimes think are not important”.

Scheepers said the plan is to “grow the programme, motivate other universities to also invest in their students through this programme, and race to become a national and maybe an international event”.

“The programme adds value to the student experience to ensure that they do not only obtain a degree during their study period, but also undergo practical application of acquired knowledge and skills through real-life situations and meaningful learning encounters,” said Scheepers.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
