Nelson Mandela oversaw a period of sustained growth when he led the country but since then the South African economy has languished. It faces growing economic and social challenges - inequality, collapsing business confidence, corruption and labour unrest.

Plus we'll be visiting a high tech energy firm called Moixa to explore whether a new kind of USB cable can drive a revolution in how we use power. Will Thomas Edison will finally triumph over Nikola Tesla after all these years, will direct current eclipse alternating current? And self-dissing. We've got Lucy Kellaway on why, when it comes to self-critisism we are often our own worst enemies.
