With her talk on ‘Breaking the walls of darkness’, Emmie Chiyindiko came in second out of the 74 pitches presented at the recent Falling Walls Science Summit.

“I need you to take a moment and imagine trying to do everything that you do every day … without reliable energy. Or I’ll ask you this … How far would you walk to charge your phone if you didn’t have electricity? Would you walk for hours? Kilometres?”

“Well, that’s what millions of people in sub-Saharan Africa do daily to charge their phones. One billion people globally don’t have access to electricity in their homes and in sub-Saharan Africa, more than half of the population remains in the dark.”

This was the introduction to Emmie Chiyindiko’s talk at the recent Falling Walls Science Summit earlier this month. Emmie, who is a PhD student in Chemistry at the University of the Free State (UFS), came in second out of the 74 pitches presented with her talk on ‘Breaking the walls of darkness’ in the ‘Breakthrough of the year in the emerging talents category’.

Falling Walls Lab is a world-class pitching competition, networking forum, and steppingstone that brings together a diverse and interdisciplinary pool of students, researchers, and early-career professionals by providing a stage for breakthrough ideas, both globally and locally. 

Emmie, who sees getting out of bed every morning as just another opportunity to “be the exceptional young black female scientist that I am”, won the local Falling Walls Lab in Cape Town in October, which resulted in her going through to the finals in Berlin. She plans to host the Falling Walls Lab in Zimbabwe, her homeland, next year. 

This innovator and science communicator, whose work has been covered in Forbes Science, News24, and the Sunday Times, among others, refers to her obtaining second place on the international stage for her research as “a tremendous achievement and a new height in my science communication career. That level of recognition from the world leaders in science, technology, and science engagement cannot be overstated”.

Ending energy poverty

She believes Sustainable Development Goal 7 – leaving no one behind and eradicating global poverty – must be preceded by intentional efforts to end energy poverty. “My research on dye-sensitised solar cells (DSSC) with special metal complexes is among the most interesting alternatives to conventional solar cells.”

Emmie explains: “The design of the cells is inspired by photosynthesis – that good old process plants use to transform sunlight into energy via chlorophyll. Instead of a leaf, the cells start with a porous, transparent film of eco-friendly titanium dioxide nanoparticles. The film is also coated with a range of different dyes that absorb scattered sunlight and fluorescent light. When sunlight hits, it excites the electrons in the dye, creating an endless supply of energy. 

The bright side of this research is that there are several benefits to this invention. It produces energy that is cheap, reliable, and relatively simple and inexpensive to produce. Emmie adds: “These next-generation cells also work impeccably in low-light and non-direct sunlight conditions, providing all-year-round energy with no disruptions. DSSC is also three times cheaper than conventional cells and produces 40% more energy.”

Improving livelihoods 

She continues: “It does not degrade in sunlight over time as do other thin-film cells, making the cells last longer, and requiring less frequent replacement. DSSCs are also mechanically strong, because they are made of lightweight materials and do not require special protection from rain or abrasive objects.”

Emmie has proven that solutions to our current energy situation are available. “We are on the cusp of an energy revolution, and we must act now. Solutions are available, and if we do not seize them during a time of crisis, when will we?”

She believes that creating technology like this can end the energy crisis and improve livelihoods. “Billions of people simply lack enough energy to build a better life. Affordable, abundant, and reliable energy can go a long way to store food, power life-saving medical equipment, and run trains and factories. It can help communities to grow and prosper and to access opportunity and dignity. Societies where people have access to energy have lower childhood mortality, a higher life expectancy, they eat better and drink cleaner water, and have a better literacy rate.”

Conference on religion and reconciliation
2011-07-25

 

At the conference were, from the left, front: Dr Frank Chikane, President of AFM International; Dr Mathole Motshekga, Chief Whip of the ANC; at the back: Rev. Maniraj Sukdaven, Head of our Department of Religion Studies; and Dr Alan Boesak, connected to our International Institute for Studies in Race, Reconciliation and Social Justice, as well as a minister in the United Reformed Church.

In recent times, reconciliation has mainly been politically driven, Dr Alan Boesak stated during a conference on religion and reconciliation. He was one of a number of prominent academic leaders from various religions who participated in the conference: Exploring religious understanding for reconciliation.The conference was presented by our Faculty of Theology and the International Institute for Studies in Race, Reconciliation and Social Justice at our university this week.

According to Dr Boesak, a theologian connected to our International Institute for Studies in Race, Reconciliation and Social Justice, reconciliation means much more than simply former enemies no longer attacking or killing one another; they also have co-exist with a positive attitude towards one another.
 
Speakers from, amongst others, the Christian, Jewish, Baha’i, Rastafarian, Islam and Buddhist religious communities shared their views on reconciliation with one another.Most of these speakers referred to the special value of humankind in each religion. A person’s life has a supernatural dimension, which ought to play a major role in the way in which people treat one another.
 
Dr Frank Chikane, President of AFM International, as well as a speaker at the event, stated that the religious community should and had to be more active in discussions about reconciliation.“If religious leaders do not talk about current issues, all kinds of voices with distorted perspectives will be heard instead,” Dr Chikane added.
 
Reconciliation can only truly take place if the contribution of each group in society is taken seriously. Apart from the high premium placed on rights in society, duties that have to be fulfilled should also be emphasised. Bishop Malusi Mpumlwana from the Ethiopian Episcopal Church is of the opinion that this sense of duty should be established in people’s frame of mind. Adv. Antony Osler pointed out from a Buddhist perspective how important it was to deal with reconciliation by living up to its principles.
 
Rev. Maniraj Sukdaven, Head of our Department of Religion Studies, is very satisfied with the high quality of the contributions during the conference.
