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.

Unbeaten and hosting the Varsity Cup final
2015-03-31

Not only will UFS Shimlas rugby team host their first-ever Varsity Cup final in Bloemfontein, but they still remain the only unbeaten side in this year’s tournament.

Shimlas knocked the defending champions, the University of Cape Town Ikeys team, out of the tournament during the semifinal in Bloemfontein on Monday 30 March 2015, beating the visitors 21-10. In Pretoria, North-West University’s Pukke crushed  top-of-the-log University of Pretoria Tukkies with a close-edged 29-28 win in the other semifinal.

It was the first-ever home semifinal for Shimlas. The home side showed determination from the start of the match when No.8 Niell Jordaan crossed the line early on for the first try of the clash. Shimlas’ Niel Marais was successful with the kick at goal, giving the home side an 8-0 lead..

Shortly afterwards, the Ikeys scored their first try of the match, but were unsuccessful with the conversion kick. Shimlas struck back with a driving maul where flank Daniel Maartens scored the second Shimlas’ try of the night, taking the scoreboard to 16-5 after yet another conversion by Marais.

Ikeys managed to get another unconverted try shortly before the halftime break, leaving the score at 16-10 after the first 40 minutes, with just two conversions separating the teams.

The second half saw less action, but Shimlas’ left wing Maphutha Dolo scored his team’s third and final try of the match, putting them in a 21-10 lead minutes before full time.

Shimlas will host Pukke for this year’s Varsity Cup final on Monday 13 April at 19:00 at Shimla Park, UFS Bloemfontein Campus.
