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.

UFS presents unique rally
2006-05-11

On Friday 9 June 2006 the University of the Free State (UFS) will present the second Amazing Race Rally in Bloemfontein. 

The rally is presented in aid of children and babies with serious diseases in the Department of Pediatrics and Child Health in the UFS Faculty of Health Sciences.  These children are in need of intensive care, and suffer from cancer, heart disease, neurological diseases and conditions, endocrinological diseases or gastro-enterological conditions.

By raising the necessary funds, equipment can be acquired to meet the unique healthcare needs of these children and babies and it will also enable the UFS to maintain the high standards of education, training and research in this field.

Last year about 12 corporate teams from among others Vodacom, Medi-Clinic, Eskom, Mimosa Mall and Nedbank and four teams from the UFS competed in the rally.  The Medi-Clinic team was the winner.

This year the teams will again follow a specific route with various check points by car.  Here they will have to complete activities or solve clues before receiving their clue to the next checkpoint.  The teams will be travelling with cars branded with the logo of the company they represent.

Companies and institutions in Bloemfontein can enter in the rally by means of sponsoring a check point, entering a team of two persons or sponsoring some aspects of the day. 

The rally will give participants an opportunity to test their knowledge of the city, as well as their time management skills, communication skills, team work and even their relationships! 

The programme will start at 12:00 on the UFS Main Campus and the first team to complete this task is the winner of Bloemfontein’s second Amazing Rainbow Rally.

Extensive publicity of the event on OFM in the weeks running up to the day will ensure that participants are easily recognised and will create a measure of excitement.

Enquiries about the rally can be directed to Ms Adéle van Aswegen at (051) 401-3535 or Ms Ilse Olivier at (051) 401-2415.
