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.

What were South Africans left with after The Spear? More importantly, what did we learn from The Spear?

These were the issues discussed at a seminar, Beyond the Spear, on the controversial Brett Murray painting at the Bloemfontein Campus of the University of the Free State (UFS) on Monday 13 August 2012.

The university hosted this seminar, Beyond the Spear, in conjunction with acclaimed journalists, to look deeper into the lessons that South Africans learnt from this painting and the reaction from the public and politicians following soon after it went on display at the Goodman Gallery in Johannesburg.

The four panellists, Mr Justice Malala (political analyst, journalist and host of the news show, The Justice Factor), Mr Nic Dawes (editor in chief of Mail & Guardian), Mr Max du Preez (investigative journalist and political columnist) and Ms Ferial Haffajee (editor of City Press), all presented their views and experiences on the public’s perceptions of this artwork.

In his opening remarks, Prof. Jonathan Jansen, Vice-Chancellor and Rector, said the purpose of the seminar was to help us make sense of what happened. Prof. Jansen also chaired this seminar.

“This being South Africa, there will be more ‘Spears’. More public crises will unfold that divide the nation and that will stir the emotions. We need to understand what happened so that we are better prepared to deal with the coming ‘Spears’.”

Issues on leadership, South Africa’s hurtful past and the freedom of expression were some of the topics raised by the panellists.

“This has taught us that South Africans – especially the older generation – still need to vent their anger… White South Africa must be patient and allow black citizens to shout at them,” said Mr Du Preez. He warned that this anger should serve a constructive purpose. In reaction to a question if Brett Murray did not disrespect Pres. Jacob Zuma’s dignity with his controversial painting, he said that this painting was “…rude and disrespectful.”

“It was meant to be. It was not honouring him.” He said that politicians will do anything, including messing with the country’s stability, to further their own interests. “From now on we need to be far more alert, far more cynical about our politicians.”

Mr Dawes shared his experience and said that the debates around The Spear were very painful considering where the nation has come from. He said the painting opened up painful pasts and difficult spaces. “It is up to the media to open up these difficult spaces.” He said the painting also brought up questions of how South Africans deal and live with pain. “South Africa must live with its past. The debate should now be how to preserve space for the country’s ghosts and how its citizens could get the resilience to deal with it.”

Ms Haffajee, who was caught in the crossfire between freedom of expression and human dignity and who refused to remove a picture of the painting from the City Press website, said that the media was viciously played by politicians.

“This had shown that achieving freedom took many lives, but it took very little to kill it.” She said The Spear is art that it is part of a rich cultural heritage of protest art.

Mr Malala said with the debates around The Spear painting, something died in South Africa. “The debate was taken away from us. We let politicians get to us.”

After the panellists delivered their presentations, Prof. Jansen led a discussion session between the audience and the panellists.
