Lucas Erasmus and Prof Hendrik Swart
Lucas Erasmus and Prof Hendrik Swart (right) are working on a joint project with Ghent University to find an attractive solution to address the energy demands of buildings, electric motor vehicles, and mobile electronics.
With a constant increase in the price of electricity, any innovation to replace this necessity in our daily lives is welcome. 

The University of the Free State (UFS), whose vision is supported by an element of innovation, welcomes the recent agreement between its Department of Physics and Ghent University.

Attractive solution

Not only will this research – which aims to develop the materials necessary for transparent solar panels – enlarge the international research footprint of the UFS, but it is also an attractive solution to address the energy demands of buildings, electric motor vehicles, and mobile electronics without affecting their appearance.

According to Prof Hendrik Swart, from the UFS Department of Physics, the agreement between the two universities entails a joint doctoral degree in which both universities will supervise the project and the awarding of the doctorate. The student, Lucas Erasmus, will conduct research at both institutions.

Transparent solar panel

The idea with the research is to develop glass that is transparent to visible light, just like the glass you find in the windows of buildings, motor vehicles, and mobile electronic devices. However, by incorporating the right phosphor materials inside the glass, the light from the sun that is invisible to the human eye (ultraviolet and infrared light) can be collected, converted, and concentrated to the sides of the glass panel where solar panels can be mounted. This invisible light can then be used to generate electricity to power these buildings, vehicles, and electronic devices. The invention is therefore a type of transparent solar panel.

Implemented in cellphone screens

This technology can be implemented in the building environment to meet the energy demands of the people inside the buildings. 

The technology is also good news for the 4,7 billion cellphone users in the world, as it can be implemented in the screens of cellphones, where the sun or the ambient light of a room can be used to power the device without affecting its appearance. 

Another possible application is in electric cars, where the windows can be used to help power the vehicle.

Low-income housing

Erasmus added: “We are also looking at implementing this idea into hard, durable plastics that can act as a replacement for zinc roofs.” 

“This will allow visible light to enter housing, and the invisible light can then be used to generate electricity. The device also concentrates the light from a large area to the small area on the sides where the solar panels are placed; therefore, reducing the number of solar panels needed and, in return, reducing the cost.”

The technology will take about a decade to implement.

“This study is currently ongoing, and we are experimenting and testing different materials in order to optimise the device in the laboratory. After this, it needs to be upscaled in order to test it in the field. It is truly the technology of the future,” said Erasmus.

Engaging men to act against gender-based violence in the Southern African context.

This was the theme of the second International Leah Tutu Symposium, hosted by the Gender Initiative of Trauma, Forgiveness and Reconciliation Studies of the University of the Free State (UFS) on Tuesday 24 February 2015.

What does it mean to be man? How can men become active in the fight against gender-based violence? And when does one say: enough is enough? Questions like these set the tone as highly-respected individuals such as Dr Mamphela Ramphele, Prof Rob Morrell, Lisa Vetten and Andy Kawa took to the stage in the Odeion on the Bloemfontein Campus.

Leah Tutu
Unfortunately, Mrs Leah Tutu could not attend this year’s event, but she still managed to send sparks of wit and insight into the auditorium. In her video message, Mrs Tutu referred to the fact that our country has “consigned discriminatory legislation to the rubbish bin of the past”, but we continue to inhabit a divided society.

“We have a constitution and bill of rights that should have sounded the death knell for patriarchy. But women are unsafe across the land,” Mrs Tutu said. “Our freedom cost too much to be left out in the rain,” she urged.

Ndiyindoda! Yes, you are a man
In Dr Ramphele’s keynote address, “Ndiyindoda! Yes, you are a man”, she scrutinised the dominant masculinity model that has supported an alpha-male mentality for millennia. A mentality that celebrates dominance, power and control – where the winner takes it all. How then, can we expect our young boys to embrace the value system of a human rights culture?

“Gender equality is at the heart of our constitutional democratic values. Yet, our society continues to privilege and celebrate the alpha male as a masculinity model,” Dr Ramphele said. This dissonance can only produce conflict and violence.

We encourage our young men to be gentle, communicative, caring people who show their emotions. And when they do, what do we as women do? Do we encourage them?

“Or do we join those who call them wimps, moffies, sissies? How do we respond when they are ridiculed?” Dr Ramphele asked. Are we, as mothers, fathers and grandparents willing to socialise our children to acknowledge a diversity of masculinities as equally valid in our society?

The new man and the new woman of the 21st century need to be liberated from the conflict-ridden dominant masculinity model. They need to be able to shape their identity in line with a value system of human rights as enshrined in our constitution.

Perhaps Dr Ramphele’s message could be summed up by one sentence: You cannot find Ubuntu in a culture of dominance.
