SOWETO, SOUTH AFRICA - FEBRUARY 7: A petrol attendant fuels a customers car at a Sasol station on February 7, 2006 in Soweto outside Johannesburg, South Africa. Sasol makes liquid fuel from coal and they provide about 28 percent of fuel needs in South Africa. Originally a German technology from the 1920s, South Africa used it to ease the fuel needs during the economic embargo in the '80s. The company is hugely profitable and is listed on The New York Stock Exchange.  (Photo by Per-Anders Pettersson/Getty Images)
