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.

Former President Nelson Mandela was part of the Moses generation that took people out of bondage. What the country now needs is the Joshua generation that will take it into the promise land.

This is according to political analyst and public commentator, Prof. Somadoda Fikeni. He was speaking to staff and students participating in the Global Leadership Summit, which took place on the Bloemfontein Campus from 8-20 July 2012. Prof. Fikeni took part in a panel discussion on Justice and Reconciliation. He and other panellists observed that there were still many challenges facing reconciliation in South Africa.

Referring to controversial statements made by Helen Zille, Julius Malema and Pieter Mulder, Prof. Fikeni said public discourse had become toxic and that the country was faced by a leadership crisis.

Ms Yasmin Sooka, a former Commissioner of the Truth and Reconciliation Commission (TRC) and Executive Director of the Foundation for Human Rights South Africa, asked if reconciliation had not come at the expense of redress. She said that to date there had been no restitution.

Ms Lihlumelo Toyana, a post-graduate student at the university, was also part of the panel. She told the audience that 18 years into democracy, there are still people waiting for justice. Toyana said young people hoped to see change and wondered if South Africans would ever sit down and have dialogue about the past. “We need closure; we need to take the country forward.”

The other panelists were lawyer, politician and former Human Rights Commissioner Prof. Leon Wessels; a professor from the University of Cape Town’s Law Faculty, Prof. Jaco Barnard-Naude; and psychologist, Prof. Alain Tschudin.
