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.

‘Leadership is formed through ethical behaviour’
2012-08-20

Mr Edward Kieswetter
20 August 2012

“Being ethical is not about what we can do, it is about what we ought to do.” This is according to Mr Edward Kieswetter, Group Executive of Alexander Forbes Limited. During his lecture to MBA students in the Business School, Mr Kieswetter allowed the audience to engage in a discussion about ethics and leadership in the business world. Mr Kieswetter is also Vice-Chairperson of the UFS Council.

Part of the lecture was discussing South Africa as a country that was not born in ethics. Mr Kieswetter commented that although context was is very important in making decisions, South African people tended to, for example, and “feed on corruption, instead of acting actively against it”. Questions about South Africa’s ethical foundation were raised. Mr Kieswetter explained that one of the greatest challenges with the South Africans was to help them understand that a person always had a choice. “If you have to compromise on your own values, you are not doing anybody justice.”

Ethics can promote common and social goals if they are not determined by what people feel and strive to reach beyond the barriers that religious beliefs put up. He shared of his life’s most valuable lessons learned about people in leadership positions. “A great leader has incredible self-awareness and displays a huge amount of humility.” He said that in life it was not about being perfect; it was rather about being authentic, even in challenging times where the outcome might affect the current situation negatively. “My greatest successes came from lessons I learned in making mistakes and growing from them.

“If you have nothing to die for, then what is there to live for?” Mr Kieswetter said when asked whether he would compromise his financial position if he did not agree with the ethics of the company he worked for. “By constantly complaining instead of progressing, we are giving up our power to change, and that is a scary thing for South Africa as a developing country.”
