While South Africa is enduring load shedding and promises are being made left, right and centre, a small organisation, Joy4Africa, is delivering alternative power to the Chris Hani section of an informal settlement in Olievenhoutbosch.
A 40-watt light in the shape of a 2-litre plastic cooldrink bottle filled with water and a few millilitres of Jik does the trick.
The first few are provided with a recycled plastic tile to fit the corrugated roof sheets with a round hole the size of a bottle.
Future sales of these tiles are left in the hands of the community to develop small business, and installation will extend business opportunities even further.
Future developments include a tyre cooker, a solar water boiler and night light.
