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.

Office of Technology Transfer receives multimillion rand grant
2016-01-15


The university’s Office of Technology Transfer (OTT) received multimillion rand funding for the office to provide much needed support for academia to have their ideas and research effectively turned into business ventures.

This grant of over R4 million by the National Intellectual Property Management Office (NIPMO), under the auspices of the Department of Science and Technology, will help the OTT to provide an enabling environment for cooperation between academia and industry to transform innovation emanating from research and development at the UFS into business ventures.

“Research and innovation plays a prominent role in the financial sustainability of an institution, in that it has the capacity to be the largest generator of third-steam income,” says Gerhard Verhoef, Director: Contracts and Innovation at the Directorate Research Development at the UFS.

“The OTT is a very new office and this grant, provided over three years, will help us fulfil our mandate.”

NIPMO aims to ensure that recipients of funding from a government funding agency assess, record and report on the benefit to society of IP emanating from publicly-financed research and development. Recipients must protect IP emanating from publicly-financed research and development from appropriation and ensure that it is available to the people of South Africa. A recipient must identify commercialisation opportunities for IP emanating from publicly-financed research and development.
