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.

Statement: Visit of the Portfolio Committee on Education to the UFS
2005-02-25

The chair of the Portfolio Committee on Education (PCE) Prof Shepherd Mayatula has commended the management of the University of the Free State (UFS) for its positive approach to the incorporation of the Vista and Qwaqwa campuses.

According to a statement issued by the university’s communication section, Prof Mayatula said that while there were outstanding issues to address, a platform had been created through the visit of the portfolio committee for the UFS to find solutions.

Speaking at the end of a visit to the Bloemfontein campus of the UFS, Prof Mayatula said: “You know the issues that exist between the three campuses and you know the solutions. You don’t need recommendations from the Committee.”

Earlier today the PCE held a three-way meeting between the PCE, the management of the UFS and the Vista Task Team, representing staff and students at the Bloemfontein campus of the former Vista University .
 

The Bloemfontein campus of the former Vista University was incorporated into the UFS in January 2004.

The multi-party delegation from the PCE was led by its chairperson, Prof S Mayatula, while the delegation from the UFS was led by the Rector and Vice-Chancellor, Prof Frederick Fourie, while the Vista Task Team was lead by Mr Paseka Mokoena.

Following a presentation by the Vista Task Team and a presentation by the UFS management, other committee members also commended the UFS for the spirit in which outstanding issues were being handled.

It was indicated by portfolio committee members that other universities have far more serious problems than the UFS, and that some of these universities have also been visited by the PCE. The UFS appears to be on the road to be an important pilot case for incorporations and mergers.

The issues that were discussed during today’s meeting included the following:

  • outstanding issues in the process of incorporating the Bloemfontein campus of the former Vista University into the UFS, including:
  • staff issues and conditions of service
  • issues of student aid and pipeline students
  • governance of the UFS
  • the long term utilisation of Vista as a site

The Rector and Vice-chancellor of the UFS, Prof Fourie, expressed his appreciation for the role played by the Portfolio Committee on Education in bringing about a common understanding of the transformation issues facing the UFS.

Prof Fourie said the Portfolio Committee’s visit was a useful intervention to bring about a sense of urgency in resolving matters affecting the Vista campus as well as the Qwaqwa campus.
