The swamps of Sudd in South Sudan are among the largest wetlands in the world. Located in the delta of White Nile, it covers the average area of 30,000 sq. km. During the raining season the wetland can extend to over 130,000 sq. km, which is as much as the size of England. The Sudd is considered almost impenetrable overland or by boat. The abundant water-loving plants form the massive moving blocks. The swamps of Sudd are inhabited by the Dinkas, one the Sudanese ethnic groups.
70-year-old French aeronautical engineer Guy Nègre has invented the AirPod, an alternative fuel vehicle powered by compressed air. To manufacture it in mass, his company (MDI) has made a partnership with Indian manufacturer Tata Motors. Several versions will be sold at around $5,000, some going to 70km/h (43 mph) and some limited at 45 km/h (28 mph). It is told that you can drive the AirPod for 100 km (62 miles) on a 1-minute recharge of compressed air. The AirPod would be used as an emission-free vehicle for urban areas, golf fields, airports and stuff like that.
