The River Nile
The Nile (Arabic: النيل, an-nīl, Ancient Egyptian iteru or Ḥ'pī, Coptic piaro or phiaro) is a major north-flowing river in Africa, generally regarded as the longest river in the world.[1]The drainage basin of the Nile covers 3254555 square kilometres (1256591 sq mi), about 10% of the area of Africa.[3] There are two great tributaries of the Nile, joining at Khartoum: the White Nile, starting in equatorial East Africa, and the Blue Nile, beginning in Ethiopia. Both branches are on the western flanks of the East African Rift, the southern part of the Great Rift Valley. Below the Blue and White Nile confluence the only remaining major tributary is the Atbara River, which originates in Ethiopia north of Lake Tana, and is around 800 kilometres (500 mi) long. During the dry period of January to June, there is typically no flow from the Atbara River. It flows only while there is rain in Ethiopia and dries very rapidly. It joins the Nile approximately 300 kilometres (200 mi) north of Khartoum. The Nile is unusual in that its last tributary (the Atbara) joins it roughly halfway to the sea. From that point north, the Nile diminishes because of evaporation. The course of the Nile in Sudan is distinctive. It flows over six groups of cataracts, from the first at Aswan to the sixth at Sabaloka (just north of Khartoum) and then turns to flow southward for a good portion of its course, before again returning to flow north to the sea. This is called the "Great Bend of the Nile". North of <b>...</b>
Narrow track vehicles - the convergence of the car and the motorcycle
As the world's roads become ever more crowded, many manufacturers are looking to single and narrow track vehicles as cars of the future which will reduce congestion. This video examines Nissans tandem two-seat, half width tilting car, the Landglider, and examines all the other work being done around the world as narrow track vehicles begin to make their case. Vehicles covered include Renault Twizy ZE, Volkswagen L1, Yamaha Tesseract, VentureOne, Peugeot Hybrid3 Evolution, Peugeot Hybrid3 Compressor, Nissan PIVO II, Lumeneo Smera, Tilting Car Project, Sidam XNovo, Piaggio MP3 HyS, Xingyue, Auto Moto, Adiva Moose, Adiva 3Route, BMW C3 Electric, Tango, and the reasons behind global traffic congestion

Prototipo Moto - Dodge Tomahawk
La Dodge Tomahawk es una moto basada en el motor Viper V-10 de 8.3 litros. Necesita 4 ruedas para poder sujetar los tremendos 500 CV de potencia que desarrolla. Cada una de las ruedas tiene un sistema de amortiguación independiente. El motor respira a través de dos cuerpos montados sobre las ruedas delanteras. Es capaz de ponerse de 0 a 100 km/h en tan solo 2.5 segundos y alcanza una velocidad máxima ( teorica ) de 643 km /h. INCREIBLE...
