Could wave power be an answer to SAs electricity crisis

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.

Rugby players still a Kovsie pride

Glory after glory, Kovsie rugby players seem to be making waves on- and off-campus in the rugby world. Four players, who formed part of this year’s formidable Shimlas squad, wore their Cheetahs jerseys in their debut cap for the Free State team in this year’s Super Rugby tournament. Niel Marais, Niell Jordaan, Elandré Huggett, and Gerhard Olivier were hand-picked to join the squad by the same man who lead Shimlas on their unbeaten streak, Franco Smith. Smith was recently announced as the Cheetahs’ new coach.

In their debut game (6 June 2015) against the Sydney-based Waratahs, Marais, Jordaan, Huggett, and Olivier had the privilege of playing alongside Tienie Burger and Henco Venter, who are also Shimlas teammates. Burger and Venter are not new to the team. Burger has been with the team since 2014 and Venter since 2013.

The young men appeared again in the game against the Blue Bulls in the final round of Super Rugby on 13 June 2015. Marais and Jordaan were part of the starting line, and were joined by Venter. It was unfortunate that the home-ground advantage did not work in the favour of the Bulls, as the team strode away with their first victory for the tournament, leaving Smith a very blissful coach.

We congratulate Tienie Burger on signing a professional contract with the Cheetahs.
