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.

“Our education system needs quality teacher education.”

This was the message from Prof Jean Baxen, Deputy Dean of Research at Rhodes University in Grahamstown. She delivered the Education Public Lecture on ‘The lives of children, citizenship and teacher education: challenges and opportunities’ at the University of the Free State’s Bloemfontein Campus.

Growing up in White River, the rural areas of Eastern Transvaal (as it was previously known), Prof Baxen took the audience on a journey of the imagination. She shared stories of how she and fellow learners walked miles to get to school and how her son found himself in a situation of being unsure about his own racial identity, questioning what it meant to be ‘coloured’. She also related stories of how teachers are not sufficiently prepared to mediate information on HIV/Aids.

These stories revealed how little teachers cared, and also how difficult and challenging it is for learners to cope in such teaching and learning environments – thus calling for quality teacher education.

She stressed the fact that quality teacher education is needed in South Africa to assist in curbing the challenges children and fellow citizens come across in our broader society. “It is important that, as teacher educators, we should groom teachers to find and understand their identity, sexuality, and also the world they live in. There is an urgent need for us to hold ourselves and others accountable and to not distance ourselves and make it someone else’s responsibility – it is our joint responsibility as citizens,” she said.

We need a pedagogy that would navigate and start formulating a language that we could use to face these challenges, she proposed.
