Our podcast guest
Prof Jeandrew Brink holds the post of Associate Professor in the Department of Mathematics and Applied
Mathematics within the Faculty of Natural and Agricultural Sciences at the University of the Free State. Her areas of interest include an analytical interest in Einstein field equations, dynamical systems, algorithms for testing general relativity
and the no-hair theorems, black holes, and gravitational waves. Prof Brink registered for a Bachelor of Sciences in 1998, continued with honours studies in 1999, and completed her master’s degree in 2000. Prof Brink’s research is on various
theoretical aspects of testing general relativity. She is a member of the MeerKAT telescope team that times and detect pulsars. She is also working with members of the Laser Interferometer Gravitational-Wave Observatory (LIGO) to find ways of using
gravitational waves to test Einstein’s theory.
Prof Brink was involved in the compilation of a video of geodesic orbits around a Manko-Novikov singularity, selected to be part of a Starmus 3 concert, the proceeds of which went towards promoting the Stephen Hawking Medal for Science Communication and
to support the charitable activities of the Stephen Hawking Foundation. It could also be part of a subsequent documentary.

François van Schalkwyk and Keenan Carelse,
UFS alumni leading the university’s United
Kingdom Alumni Chapter, have put their voices together to produce and direct the podcast series. Intended to reconnect alumni with the university and their university experience, the podcasts will be featured on the first Monday of every month,
ending in November 2021. Our featured alumni share and reflect on their experiences at the UFS, how it has shaped their lives, and relate why their ongoing association with the UFS is still relevant and important. The podcasts are authentic
conversations – they provide an opportunity for the university to understand and learn about the experiences of its alumni and to celebrate the diversity and touchpoints that unite them.

Renewable energy systems an economical investment for the UFS

Renewable energy systems are said to be very expensive to implement initially, but in the long run they provide high economic returns.
With their decision to install renewable energy, the University of the Free State Department of Facilities Planning has now also adopted this innovative technology. They have chosen less capital-intensive solar power-generating options to generate electricity in various buildings and parking areas on all three UFS campuses.
“As per the UFS Energy Management Policy, all designs incorporate efficient, renewable energy sources varying from LED lights to solar power,” says Anton Calitz, Electrical Engineer in University Estates’ Department of Facilities Management.
South Campus taking the lead in renewable energy usage
In December 2016, a total of 26 solar-driven LED street-light poles were installed at the recently built Legae Residence’s parking area and the perimeter security area on the South Campus. This low-maintenance system improves security after dark and is independent of the national power supply, which is an important advantage during power outages. With no requirements for major earthworks and cable setting, operational costs are reduced.
The recently built infrastructure also takes pride in being the first to have a greywater system installed. This system will also be installed at three other residences on the Bloemfontein Campus in 2017. Greywater is made up of bath, shower, and bathroom sink water. The water is reused for toilet flushing, as well as for irrigation purposes.
Various UFS electrical operations to depend on solar power
On the Bloemfontein and Qwaqwa Campuses, the computer laboratories as well as the Thakaneng Bridge Student Centre and the projected Afromontane Research Centre will be equipped with freestanding roof solar solutions during 2017. These systems are designed to operate independently of the power grid (Eskom).
The systems only operate during sunlight hours when the PV solar panels are heated by the sun, making them suitable for operations such as ventilation fans, water pumps, and small circulation pumps for solar thermal water-heating systems.
