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.

Two research chairs awarded to UFS women
2015-09-15


Prof Pumla Gobodo-Madikizela

Two professors at the University of the Free State (UFS) have just been chosen as recipients of research chairs by the National Research Foundation’s South African Research Chair Initiative.

The research chairs are a massive financial injection for research in each of the relevant disciplines – that of Profs Pumla Gobodo-Madikizela from the Centre for Trauma, Forgiveness, and Reconciliation Studies at the UFS, and Felicity Burt from the Department of Medical Microbiology in the Faculty of Health Sciences.

Profs Gobodo-Madikizela and Burt are two of 42 female researchers in the country receiving research chairs as an initiative to give due recognition to women in research.

Profs Hendrik Swart, from our Departement of Physics and Melany Walker, Director, Centre for Research on Higher Education and Development, each also holds research chairs by the NRF. A third research chair has also been granted to the UFS Department of Plant Sciences for the research in field crops.


Prof Felicity Burt

The work of Prof Burt’s research chair is to investigate medically significant vector-borne and zoonotic viruses currently circulating; to define associations between these viruses and specific disease manifestations that have previously not been described in our region, to increase awareness of these pathogens; to further our understanding of host immune responses, which should facilitate development of novel treatments or vaccines and drug discovery.

Prof Gobodo-Madikizela, who has received international recognition for her work on forgiveness studies, will use this research chair to investigate historical trauma within two African contexts – those of South Africa and Rwanda. She hopes to gain insight into the role that memory plays in the formation of the experience of trauma, and to bring about healing of the trauma.

Prof Corli Witthuhn, Vice-Rector: Research at the UFS, expressed her pride on the announcement.

“We are extremely proud of the national recognition these two outstanding women researchers received.  The UFS strives for research excellence, and the five current NRF research chairs, as well as two NRF A-graded researchers who are at the forefront of their disciplines globally, indicates our continued commitment to innovating, relevant, and high-impact research.  We are excited about the progress of the past two years to position the UFS as a national leader in research.”
