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.

Judge Deon van Zyl donates prominent collection of legal books to the UFS
2009-12-08

 His Honourable Judge Deon van Zyl, Inspecting Judge of Prisons recently donated his collection history of law books, including valuable editions of Roman Dutch law resources and works on Roman law and history of law to the Faculty of Law at the University of the Free State (UFS). “I trust that this will be of use as aids for research and training in law,” Judge Van Zyl said.

This is the biggest collection ever that the faculty received.

Prof. Johan Henning, Dean of the Faculty of Law says this collection is of invaluable worth for the faculty as well as the UFS. This unique source will enables the faculty to place postgraduate learning and research about the common law on a much higher level. “Without this collection the faculty will have been much poorer,” Prof. Henning said.

Judge Van Zyl made this donation showing his appreciation for what the Faculty has managed to accomplish over the years. At age 26, from 1 July 1971 to 31 December 1973, he was the first Head of and Professor in the Department of Roman Law and History of Law who taught in the Faculty of Law at the UFS.
