The Institute of Electrical and Electronics Engineers is a professional association (IEEE), its South African Section in 2015 developed a project, "Light (Sun in a Bottle)" that helped solve a major environmental problem in the informal settlement of Kathrada Park. This settlement is home to some of Johannesburg's poorest residents. Without access to electricity, kids are unable to study and complete their homework unless they use candlelight, which poses a serious hazard. Recognizing the need to improve on the community's living conditions.

An Engineering Projects in Community Service (EPICS)-in-IEEE project was implemented at the University of Johannesburg (UJ) through the Faculty of Engineering and the Built Environment.

EPICS in IEEE not only assists communities with local community improvement goals but also empowering students to pursue engineering for community improvement as a career.

A grant from the IEEE was awarded in-order to complete this project provided the EPICS criteria were followed.

As EPICS-in-IEEE requires, the partners in this project included a UJ post grad member, a non-governmental organization (NGO), Engineers without Borders-UJ (EWB-UJ) who are primarily engineering students and secondary school learners (the pre-university component) from UJ Metropolitan Academy.

As the name suggests, "Light (Sun in a Bottle)" involves a glass bottle with water and suspending it on the roof of a shack to provide a working, energy-efficient lighting system. During the day, sunlight strikes the bottle. Due  to the  reaction and refraction of light  as it goes through a change  of medium, from air to water, light  rays are  scattered evenly throughout  the  inside  of the  shack. In the evening, a small solar cell is fixed at the top of the bottle. This  solar cell is  connected  to  a circuit  that  charges a rechargeable  battery, which  then powers small numbers of Light  Emitting  Diodes (LEDs) inside  the  bottle. With a simple flick of the switch, the solar-charged LED units, with the aid of the refraction property of the water, can shed enough intensity to illuminate the household.

Engineering students and high school learners worked together in completing this project.

Mohamed Sameer Hoosain a Masters graduate in electrical engineering led the initiative under the guidance and supervision of Prof Saurabh Sinha.

With technology for humanity in mind and as we move in the direction of industry 4.0, The EPICS  in IEEE concept  contributes towards taking  engineering  to the  broader community and  empower students  for careers  in  the  private, public, and non-profit  sectors.
