Gideon Greyvenstein holds a PhD in mechanical engineering from the University of Pretoria and a master’s in business leadership (MBL) from UNISA. He is registered as a professional engineer with the Engineering Council of South Africa and the Engineering Institution of Zambia.

He lectured engineering at the North-West University in SA for more than 25 years and held the positions of Director of the School of Mechanical Engineering and Dean of the Faculty of Engineering. His main area of research was the modelling of thermal-fluid systems. This work led to the development of the thermal-fluid systems code Flownex, which today is used by leading international companies such as Rolls Royce and Lufthansa. He also spearheaded the development of a range of water heating heat pumps which is still being produced today. In 2005 he won the National Science and Technology Forum’s (NSTF) award for the individual who has made the most outstanding contribution to science, engineering and technology (SET) in South Africa through research and its outputs over the previous five years in any sector or discipline of SET.

In the mid-1990s he founded the engineering company M-Tech Industrial (Pty) Ltd and served as CEO of the company until 2008 when he was appointed General Manager Engineering of PBMR, a state-owned nuclear engineering company tasked with the development of a new inherently safe gas-cooled nuclear reactor, called the Pebble Bed Modular Reactor or PBMR for short. After the PBMR project was terminated by government he founded Sunray Power Company in 2013 in Zambia.

He served on various councils, boards and committees during his career. Amongst these are board member of the Engineering Council of South Africa (ECSA), board member of the Nuclear Energy Corporation of South Africa (NECSA) and member of the Standing Advisory Group for Nuclear Energy (SAGNE) of the International Atomic Energy Agency (IAEA).

Anton obtained his Bachelors’ degree in mechanical engineering in 2006 and his Master’s degree in Nuclear Engineering in 2008 from the North West University. It was during his Master’s degree study in 2007 when he was appointed by M-Tech Industrial to work at the High Temperature Test Unit in Potchefstroom for the PBMR project.

Anton was also send to the Helium Test Facility at Pelindaba to commission the gas analyzer. After these projects he continued working for M-Tech Industrial on various “first of a kind’ plants and equipment which involved many different engineering challenges that provided much personal experience. These included plant operations, mechanical design, testing and commissioning, research and development, instrumentation with data processing and the interpretation thereof. Anton was also responsible for training programs on some of these projects.

In 2012 Anton decided to set his focus on the well-being of people living in rural areas and collaborated with Touching Africa Initiative to develop a business case for the establishment of a Community Center in Promosa Township, Potchefstroom. In the same year he started working for Enernex Solutions (PTY) Ltd., founded by Dr Gideon Greyvenstein, which also focused on bringing change to people living in rural areas, especially in Zambia.
