Could wave power be an answer to SAs electricity crisis
Attending a recent guest lecture, were from the left: Prof Marian Tredoux UFS Department of Geology, Prof Stoffel Fourie fromWalter Sisulu University, and Thoriso Lekoetje a third-year UFS Geology student.
South Africa has a 2800-km long coastline with high wave energy potential that can generate electricity. Presenting a lecture at the UFS Department of Geology, Prof Stoffel Fourie discussed wave power as a possible solution to the country’s electricity needs. Prof Fourie is a geophysicist and the chairperson of research and development in the faculty of engineering at Walter Sisulu University.

Power at any time
Wave power is a renewable and sustainable resource. “It can provide continuous base load power because wave energy systems do not suffer from ‘time of day’ issues as other renewable energy options. This means that it can generate power at any time of the day,” said Prof Fourie. 
Discussed also was the wave power advantages and disadvantages. 

Wave energy advantages
• Wave energy is a reliable renewable energy resource;

• Reduces dependency on fossil fuels;

• Wave energy is predictable and consistent;

• Generates little or no pollution to the environment compared to other energy resources; and

• Presents no barriers or difficulty to migrating fish and aquatic animals.

Wave energy disadvantages
• Wave energy conversion devices are location dependent, thus limiting possible sites where they can be implemented;

• Offshore wave energy devices can be a threat to shipping as they are too small to detect by radar; and

• High capital investment required for start-up costs, construction and maintenance.

“Looking at both advantages and disadvantages, there is no doubt that South Africa can use this method to harvest energy. With the right investment and political buy-in, wave power could provide a continuous supply of energy and contribute to all South Africa’s electricity needs,” Prof Fourie said.

Kovsie Netball team aims for first home final on Monday 12 October 2015
2015-10-09

Kovsies Netball has been unbeaten this year.

The University of the Free State (UFS) netball team  is hoping to continue its good performance in the Varsity Sport series against the North-West University on Monday 12 October 2015 at 19:00, in order to reach the finals for a third consecutive year.

The teams will meet in the Callie Human Centre on the Bloemfontein Campus for a follow-up of last year’s semi-final. Kovsies won that that game in Bloemfontein with a score of 51-45.

If the home team prevails, they will be hosting a final for the first time.

The Kovsies, who were unbeaten this year, and finished at the top of the log, were the champions in the first two seasons, but had to play away from home in the final against Pukke in 2013 and Tuks in 2014.

The last league match they lost against Pukke was in 2013. The score in Pretoria was 47-60 in favour of the Pukke.

Many of the clashes between the teams have been very close games. Last year, there was a 45-45 draw in Potchefstroom.

In the first round of 2015 between Kovsies and Pukke in Bloemfontein, the UFS won by 47-38.

In their final league match in Stellenbosch on Monday 5 October 2015, Kovsies won against Maties by 41-33, while the Pukke, who ended fourth on the log, defeated the Madibaz 65-32 in Potchefstroom.

In the other semi-final on Monday, Tukkies and Maties, second and third respectively on the log, will play against each other in Pretoria. This match will be broadcast live on a big screen in the Callie Human Centre on Monday.

The Kovsie captain, Karla Mostert, who will be playing for Bath in England next year, is currently ahead on votes for Player of the Series. Last year, she was also Player of the Series. Fans may vote for her on the Varsity Sport Facebook page at https://www.facebook.com/varsitysportsSA.
