Could wave power be an answer to SAs electricity crisis

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.

UFS sets deadline for applications
2005-11-14

The University of the Free State (UFS) calls on all prospective students wishing to study at the UFS in 2006 to submit their applications for admission by no later than 30 November 2005.

“This applies to first-time entering first-year students, senior students who have interrupted their studies for at least one year and undergraduate students from other educational institutions,” said Mr Vernon Collett, Registrar:  Academic Student Services at the UFS.

According to Mr Collett students whose applications for admission are received after 30 November 2005 and until 25 January 2006 will be accepted subject to the availability of place on the programme they applied for. 

“After 30 November 2005 academic advice within a one-stop service may not be available to students and no conditional exemptions will be considered.  No transfer students from other tertiary institutions will also be accepted after 30 November 2005,” said Mr Collett.

Prospective students who want to apply must pay a non-refundable fee of R110 into a designated account, which will be provided when the application form is sent to them.  The signed application form must be accompanied by a certified copy of the prospective student’s identity document or passport and a proof of payment of the application fee.  The application form of a minor must be signed by his/her parent or guardian and the field of study should be clearly indicated.

“A total of 25 251 students are registered at the UFS Main Campus this year.  We expect a considerable number of applications and foresee that our numbers for next year will be similar to what it is now,” said Mr Collett.

First-time entering first-year students on the Main Campus will be welcomed by the Rector and Vice-Chancellor of the UFS, Prof Frederick Fourie, on 14 January 2006 at 11:00 in the Callie Human Centre.

The registration of first-time entering first-year students will commence on 17 January 2006 and that of senior students on 23 January 2006 at the Callie Human Centre according to a programme.  Students who applied for admission after 30 November 2005 can register from 2 February 2006.  Lectures will commence on 6 February 2006 and the registration process will end on 11 February 2006.

Prospective students who want to apply for admission or who have any enquiries can call (051) 401-3000 or visit the UFS web site at www.uovs.ac.za.
