Before the event, he didn’t think it was possible to set two new national track records within 18 hours, but he gained so much confidence after the first win that Danie Breitenbach decided to simply go for it.

With the help of his guide, Oratile Molale, the final-year Law student at the University of the Free State bettered his own South African records in the 800 m (2:05,04) and 1 500 m (4:25.59) in the T11 category (completely blind athletes). This was at the SASAPD National Championships for physically disabled and visually impaired athletes in Stellenbosch. His previous records were set in 2017.

“I struggled with various injuries over a period of two and a half years, during which I never managed to gain my top form. Since January, I was able to train injury-free. I was confident that I could improve on my 800 m record of 2:08,90. Having had such a great first race gave me the confidence to give the 1 500 m record a go the next morning,” Breitenbach (24) said.

With no 800 m event at the Paralympic Games or the World Championships, he is hoping to qualify in the 1 500 m for next year’s Paralympic Games. “I will have to improve on my time, as they are only taking about the top-five in the world. I’m sure I can go quicker with another couple of months of training.”

“I’ve been to a few international events, but these two records will rate among my best achievements. I compete in the 400 m, 800 m, and 1 500 m, but the 800 m is my favourite. I enjoy the balance between speed and endurance.”

Breitenbach was born with limited vision, but at the age of ten became completely blind after suffering a retinal release.

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.
