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.

ANC is not a party of the people - Mbeki
2010-08-30

 

 

“The unions in this country do not understand the political economy of South Africa. They think that the ANC is the party of the people. The ANC is the party of the black middle class. The fact that the masses vote for it does not mean they control it. The policies of the ANC favour the black middle class and the established businesses. They do not favour the working class.”

This was said by renowned economic and political commentator Mr Moeletsi Mbeki, brother of former president Thabo Mbeki, during a guest lecture he recently presented to Economics students of the University of the Free State (UFS) in Bloemfontein.

“You just have to look at the types of houses that the ANC government builds for ordinary South Africans,” he said.

“If you had a party that was a pro-working class party it would not have built these so-called RDP houses that are being built by the ANC government. The unions have all along been under the illusion that the ANC is the government of the working class and (Zwelinzima) Vavi and them are now beginning to realise that this is not the case.

“The public-sector workers are in a special dilemma. They think the ANC is their ally but at the same time they feel they are not getting any benefits out of this alliance. Therefore you are beginning to get a very acrimonious environment emerging between the public-sector unions and the government.”

Regarding the current issue of the Protection of Information Bill and the proposed media tribunal that have brought the media and the government onto a collision course, Mbeki said the ANC government was trying to muzzle the media because it wanted to safeguard corruption within government.

“The question of freedom of information is very closely linked to the rise in corruption in the government,” he said.

“What the politicians are doing is that they are trying to hide that corruption. The media in this country have been playing a very critical role in exposing cases of corruption. That is why Vavi now has bodyguards.”

He said he recently met Vavi, the General Secretary of Cosatu, surrounded by four bodyguards. He said Vavi told him that he was getting death threats because he was opposing corruption in government.

Mbeki said the economic policies of South Africa were the “worst in the world” because they benefited people who were already rich and militated against the emergence of entrepreneurs.

“In fact, one of the serious downsides of Black Economic Empowerment (BEE) is that it takes people who should normally be entrepreneurs and who should be creating new companies and new jobs, out of that space and just makes them wealthy. BEE has been a disaster because it created this massive economic inequality; it created this class of idle rich who have tons of money but do nothing,” he added.

He said the under-investment in the economy was having dire consequences in terms of unemployment and poverty. He said this, coupled with the growth of consumption that Black Nationalism was driving, was actually driving down the ability of the economy to absorb labour.

“What really lies at the bottom of our economic problems in South Africa is that we have too much of a one-party dominance of our political system. We need more competition in our political system and until we realise the policies of the ANC are not going to change,” he said.

Mbeki’s guest lecture was on the topic: Architects of Poverty: Why African capitalism needs changing.
