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.

The first-year students’ swimming gala is always a much-anticipated event, especially after the participants have rubbed shoulders with residence competitors at the first-year athletics. This year’s gala, which took place on 5 February 2016 at the Lindsay Saker swimming pool on the Bloemfontein Campus, proved as exhilarating as always.

The body painting competition, held through the University of the Free State Student Representative Council (SRC) portfolio of Media & Marketing, and sponsored by ABSA, was re-introduced.

Colleges in colour

Before the swimming, spectators had the opportunity to look at the body painting creations presented by each college. Colleges chose one of ten themes randomly. Nonetheless, true artistry was on display. South College were awarded the body painting floating trophy.

When asked about this year's competition, SRC Media & Marketing, Peo Segano, had this to say: "I questioned the relevance of it, but I got the opinion of the residence committees and how they felt about it.
“The majority voted for it to be re-introduced, and ABSA was more than happy to sponsor the paints and some treats.”

Soon after that, it was down to the business. The swimming started, and each residence was cheering ecstatically for their fellow freshmen as everyone waited in anticipation to see who would be crowned the kings or queens of the water.

Kings and queens of the water

Although many had sung their voices away, they continued to show their spirit through dance and movement. Then, residences were ready to hear whether it had all paid off. Armentum showed consistent effort in this regard, thus ensuring them of the spirit trophy.

To close off the festivities, the final announcements were made. Sonnedou was crowned the female residence winners, while Abraham Fischer (Vishuis) received the title of best male residence.
