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.

Eusibius McKaiser gives first talk on new book at Kovsies

Students and staff from our university got the first glimpse of political and social commentator Eusibius McKaiser’s new book, There is a Bantu in my bathroom, during a public lecture of the same title held by the author on the Bloemfontein Campus.

McKaiser told the audience that they were amongst the first people to get a preview of his book, a collection of essays on race, sexuality and politics.

His talk centred on domestic race relationships, posing the question whether it was acceptable to have racial preferences with regard to whom you live with. Recounting an incident he encountered while looking for a flat in Sandton, McKaiser said the country was still many kilometres away from the end-goal of non-racialism.

McKaiser, who hosted a weekly politics and morality show on Talk Radio 702, and is a weekly contributor to The New York Times, said the litmus test for non-racialism in South Africa was not what people utter in a public space, but rather what was said in private.

“We need to talk more about the domestic space. In public, we are very insincere and quick to preach non-racialism.”

Recounting conversations he had with Talk Radio 702 listeners on the incident, McKaiser said that preference about whom you live with was not specific to white people’s attitude. He said many of his black listeners also felt uncomfortable living with a white person. “The question is, ‘What do these preferences say about you? What does it say about where we are as a country and people’s commitment to non-racialism?’”

McKaiser was the guest of the International Institute for Studies in Race, Reconciliation and Social Justice.
