On the drive out of Cape Town airport a sprawling patchwork of tin shacks lines the freeway for 20km. This is Khaletshiya, an informal settlement housing thousands of people.
Even the small holiday town of Kleinmond, where the Grail Centre is located, has an informal settlement. Kleinmond is not cramped and winding like so many UK towns and villages: rather, it is made up of orderly grids of streets and avenues where the white people live. And then in an area a tiny fraction of the size, the shimmering tin roofs house the same number of African people as the neat squares of houses do white.
One task I will be helping with next week is re-writing user manuals for solar panels, so that they can be understood by the people who will be moving into new government-built houses with solar hot water and/or PV. Many of the people who move into these houses will never have lived in a brick house before.
