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.

Unleash your inner sparkle at The Color Run’s Varsity Tour. The University of the Free State is a proud host of the 2016 Bloemfontein edition. Be counted among the 5 million Color Runners worldwide who walk, skip, shimmy, or hop for five kilometres in the name of fun and charity.

 

The Color Run is the largest series of events in the world promoting healthiness and happiness. Arina Engelbrecht, Chief Officer at the Health and Wellness Centre, believes that “active people are happy people.” Consequently, she encourages students, staff members, and the community to join in the festivities.

Run to make a difference

Wearing white and being doused from head to toe in the colours of the rainbow while exercising is a very different way of extending a helping hand to those in need. For every ticket sold, R10 will be donated to the No Student Hungry campaign by The Color Run and Capitec Bank.

After running through four colour stations, a spectacular show awaits you at the finish line. The Finish Festival is a combination of colour throws, rainbows, glitter, music, and dancing.  

The Color Run takes place on:

Date: 27 February 2016
Time: 16:00
Place: Cricket Grounds, Bloemfontein Campus.

Tickets are available online: www.thecolorrun.co.za at R250 for the public, R190 for students, including a goodie bag, or R90 without a goodie bag. Children under 10 years of age enter free. You will receive a R200 coupon to spend on The Color Run goodies or any product of your choice. Goodie bags may be collected at the Cricket Grounds from 25 February 2016.
