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.

The University of the Free State (UFS) will confer three honorary doctorates at the Summer graduation ceremony on 6 December 2012. One of the world’s foremost philosophers is among those to be honoured. Prof. Martha Nussbaum, described by The New York Times as “one of the most prominent female philosophers in America”, will be honoured with a D.Litt. degree in the Faculty of Humanities. Judge F.D.J. Brand, a former Constitutional Court judge, and Prof. Otto Walter Prozesky, one of the country’s foremost medical researchers, will also receive honorary doctorates.

Prof. Nussbaum, who has honorary doctorates from 40 colleges and universities in America, Canada, Asia and Europe, is recognised for her intellectual and public contribution to human development. She is the Ernst Freund Distinguished Service Professor of Law and Ethics at the University of Chicago and an active member of the American Philosophy Association. Prof. Nussbaum is well-known and respected as a public intellectual and is considered to be one of the most prominent philosophers in the world.

Prof. Prozesky is to be honoured for the important role that he played in the field of medical research, especially as the President of the Medical Research Council and as researcher/educator in the field of virology and HIV/Aids. He is to receive an honorary degree in Medicine in the Faculty of Health Sciences.

Judge Brand, Extraordinary Professor in Private Law in the Faculty of Law at the UFS, is to receive a Doctor Legum degree in recognition of his considerable contribution to the legal science. More than 120 of his judgments are reported in South African legal reports. A review of recent South African legal journals (over the past five years) shows that reference is made to his judgments in at least 30 articles and case discussions.

The Summer graduation ceremony will be held in the Callie Human Centre on the Bloemfontein Campus and will take place in two ceremonies. At 10:15, master’s degrees and doctorates will be awarded, and at 15:15 qualifications will be awarded in a combined graduation ceremony of the Faculty of Health Sciences and the School of Open Learning.

  • Prof. Martha Nussbaum will lead a conversation with members of the public and the campus community on 7 December 2012. On 8 December 2012, she is the main speaker at the UFS’s conference on “Engaging the Other: Empathy and Breaking Transgenerational Cycles of Repetition” on the Bloemfontein Campus.
