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.”

UFS helps to renovate schools
2005-10-10

About 250 hostel students of the University of the Free State's (UFS) main campus yesterday painted and renovated four schools in the black townships of Bloemfontein.  This was part of Kovsie Rag's new approach to be more directly involved with communities.

Students were transported with busses and performed tasks such as the painting of class rooms and outside walls and the cleaning and painting of gutters and window panes.  The painting was judged by a panel of judges, that included the Rector and Vice-Chancellor, Prof Frederick Fourie.  These points will contribute to the each hostel's final point in the Rag fund raising campaign for 2005/2006.

 

 

Some of the students who painted the gutters of Maboloka Primary School in Bochabelo were from the left Ms Tume Kowang (18) (first year student in B Accounting from NJ van der Merwe hostel); Ms  Gloria Mangwane (19) (third year student in B Sc Biochemy from NJ van der Merwe hostel); Ms Adri Ras (21) (second year student in Occupational Therapy from Emily Hobhouse hostel) and Ms Malandi Els (20) (third year student in B Exercise and Feeding from Emily Hobhouse hostel).

UFS Rag and Eimpa paints assist with upgrading of schools

The spirit of Ubuntu will this year be truly reflected in the University of the Free State’s (UFS) Rag community out reach programme when senior students from the 23 hostels on the Main Campus will visit four less-privileged schools in the Mangaung area on Saturday 8 October 2005 to assist these schools in the upgrading of facilities.

The same day (Saturday 8 October 2005) the UFS first year students will visit the neighbourhoods in Bloemfontein from 08:00-13:00 to raise funds on an Ubuntu donation lists for Rag 2005/2006.

The Ubuntu project was started about seven years ago and it has grown each year. In the past the project was associated with a fundraising leg and a hostel publicity leg.  This year the aim is to involve the community to demonstrate how important fundraising initiatives are to help those less-privileged. 
 
The schools that will be visited are Legae Intermediary School in Batho, Mothusi Primary School in Rocklands, and the Maboloka and Lesedi Primary Schools in Bochabelo.  The schools in the Manugaung area had until 31 August 2005 to complete a questionnaire identifying what assistance is needed.  The Rag office, with the help of professional consultants from Eimpa Paints, chose four schools and visited each one to determine material/s needed to complete the work. 

Eimpa Paints is a partner of the Ubuntu project and will be sponsoring all paint necessary to complete the work at the schools.  All other material/s needed will be supplied by the UFS Rag office.

The hostels are divided into project teams and will clean and paint gutters and window sills and paint the walls of classrooms and outside walls.  At Maboloka School for instance, a project team will also to paint a wall with colourful characters.
