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.

DB Prinsloo has been appointed as Director of KovsieSport, effective from 1 April 2012. He has been acting in this position since 2010.

Apart from leading this division for some time, DB has been involved as a sport manager at KovsieAthletics since 2003. “Athletics is my speciality sport, but during the past two years as acting director, I have managed to create a balance and I was able to divide my time in order to serve all the sporting codes.”

He is very excited about his appointment. “It’s such a privilege. I have been a Kovsie since my first year in 1982, and I am really proud to be able to go the distance,” he says.

Regarding his vision for KovsieSport, DB says, “I would like to see Kovsies become the first choice university in South Africa for students who are interested in sport – be it performance sport or recreational sport.”

He finds students’ involvement in sport at university important. “I would like to see us increase our excellence, something we are already working hard to achieve. Participating in sport is a lifestyle choice and I would like to see all students participating in our recreational sporting activities. A healthy body is home to a healthy spirit,” he says.
