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.

Student gives hope to childhood cancer patients
2015-10-16


Siphokuhle Jama believes that the underprivileged are also destined to reign.

The inaugural ‘Dance and Musical Childhood Cancer Fundraising Day’, held on Saturday 26 September 2015 at the Free State Childhood Cancer (CHOC) Foundation, was “a huge success,” according to Siphokuhle Jama, the organiser.

Siphokuhle is a second-year BSc Agricultural Economics student at the University of the Free State (UFS), who has devoted his life to bettering the lives of the less fortunate. The 21-year-old self-proclaimed motivational speaker, entrepreneur, and budding author was inspired by his humble beginnings to found the Destined to Reign Foundation, which champions various community initiatives in both his home town of Mtata and Bloemfontein.

To support the fight against childhood cancer, the young philanthropist took it upon himself to invite music and dance fanatics either to perform or to enjoy spectatorship for a good cause. The impressive support received from the UFS, Universitas Academic Hospital, and Central University of Technology (CUT), various artists, and the community has contributed towards ensuring that the inaugural fundraiser was a prelude to annual events to come.

Singers, dancers, and poets entertained the audience with vigour, making the day one of the most special for the young children, who spend their days and nights at the CHOC House, with little to do but undergo radiation and chemotherapy and await a discharge date. .

All proceeds went towards basic needs, such as food, toiletries, and clothing for the children residing at the House, which is located in the same suburb as our university. In addition to accommodating dozens of cancer patients and their mothers, the House also assists with the treatment and rehabilitation of children suffering from life-threatening blood disorders. Thus, the fundraiser served to promote awareness of these health conditions.

Siphokuhle’s passion for giving hope to the underprivileged was unveiled by a school community engagement project 14 years ago. He has never looked back.“It has always been in my heart to serve my community,” he said.
