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.

Seminar puts language issues under spotlight
2012-06-29

The South African Languages Bill does not meet the Constitution’s requirements and is not doing much to curb English monolingualism.

This viewpoint of a number of critics was discussed at a language seminar at the University of the Free State (UFS) this week.

The Faculty of the Humanities at the UFS presented the seminar on the Bloemfontein Campus, where interested parties could discuss issues and developments relating to the South African Languages Bill.

The seminar formed part of the combined annual conference of the South African Applied Linguistics Association, the Linguistic Society of Southern Africa and the South African Association for Language Teachers.

At the conference, the rich diversity of language and also the complexity of language in South Africa was recognised.

The latest South African Languages Bill has attracted much interest and varied viewpoints this past year.

One of the most significant - and also the most controversial - suggestion of the present bill is to extend the present bi-language obligation to a four-language obligation, which implies that at least one African language is added to the present formula.

Furthermore, there are other important stipulations regarding the establishment of language units that will have implications for the public service, and specifically, for language practitioners.

Prof. Koos Malan, a Constitutional Law expert from the University of Pretoria, speaking during a discussion session, said: “Language determination in constitutions and language legislation are indications of the official ideology towards dealing with language and cultural diversity in the specific state. The ideology can range from the support of multilingualism – at the one extreme – to the other extreme, where only one language will get preference as the official language.”
