Abstract :
Among all the technological attractions of the 2012 olympics, there is one that I\´ve been obsessively trying to stay away from, despite the fact that it has quickly become an unavoidable part of east london\´s skyline, and that Mayor Boris Johnson branded it "a fantastic piece of engineering". I am talking about the spectacular (in the true sense of this word) Emirates Air line - a one-kilometre-long cable-car link across the River Thames, built at the cost of ??44m and with the help of MDG (that\´s \´Monocable Detachable Gondola\´ to you) technology, whereby one and the same cable is used for both propulsion and support of the gondolas.
