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.

It’s time for Stagedoor again!
2013-03-12

 

12 March 2013

It’s time for Stagedoor again! Mounting excitement is spreading across the Bloemfontein Campus in anticipation for this annual art and culture event.

Stagedoor is a fun-filled musical theatre competition between campus and city residences. This year's theme is ‘LIKE A BOSS’ and residences will battling it out in the rotations on 12 and 13 March 2013. Finals will take place on Saturday 16 March.

“This year we're excited to welcome two new residences, Outeniqua and ConLaurês, to the competition,” says Tonderai Chiyindiko, Senior Officer: Arts and Culture: Student Life and Leadership.

“We've also aligned the rotations in line with our Colleges format system. So what that means is in each college three residences were randomly chosen by all the Residence Committee members for Arts and Culture to be the main host venues for each particular college.”

The number of finalists has also been increased to seven female and six male residences.

Rotations Venues

West College: Conlaures, Outeniqua, Vishuis
South College: Emily Hobhouse, Armentum
North College: Vergeet-My-Nie, Madelief, Tswelopele
East College: Khayalami, Roosmaryn
Central College: Soetdoring, Karee

Tickets for the final on 16 March: R30 Students; R50 Non-students.
Venue: Kovsie Church
Tickets are available in office 46 in the SRC Building.
