Eco-vehicle Race
Join the UFS on 13 May 2023 at 09:00 (student performances at 09:00 and race at 10:15) on the road around the UFS Odeion School of Music for the annual Kovsie ACT Eco-Vehicle Race. Don't miss out on this incredible display of endurance; support your favourite team to victory!

Kovsie ACT at the University of the Free State (UFS) is presenting the sixth Kovsie Eco-Vehicle Race this year.

Come and show your support for our students who will be representing our colleges and three campuses, along with the Central University of Technology. Be a part of the action:

Date: Saturday 13 May 2023
Time: 09:00 Performances by student artists
Time: 10:15 Official start of Eco-Vehicle Race
Venue: UFS Odeion School of Music parking area

The Eco-Vehicle Race represents the last phase of a nine-month co-curricular skills programme, providing our students with a set of skills that prepare them for the world of work. 

In this programme where students are equipped with basic knowledge and skills on sustainable energy, they get the opportunity not only to race the eco-vehicles, but to also understand the workings of the vehicle, which is critical for repairs done by the team during the race. 

Our students will be competing in three events:

  • Obstacle course: Teams will be challenged by obstacles to test their control over the car.
  • Smart lap: A timed lap in which the drivers take the main track for the first time.
  • Endurance race: The teams need to finish as many laps as possible using the least amount of energy in 45 minutes. 
The winners of the three events will each receive a trophy. There will be a trophy for the best pit stop as well as a spirit cup for the team with the best energy and support from the audience.

Come and support our students as they showcase their ingenuity and endurance. Don't miss out on the action! For more information, click here to contact Jady Carelse.

Car manufacturers will also exhibit hybrid/electric vehicles; come and view the exhibition and learn more about how these cars work and their benefits.

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
