The Olympic Torch is based on traditional scrolls and uses a traditional Chinese design known as "Lucky Cloud". It is made from aluminum. It is 72 centimetres high and weighs 985 grams. The torch is designed to remain lit in 65 kilometre per hour (37 mile per hour) winds, and in rain of up to 50 millimetres (2 inches) per hour. An ignition key is used to ignite and extinguish the flame. The torch is fueled by cans of propane. Each can will light the torch for 15 minutes. It is designed by a team from Lenovo Group. The Torch is designed in reference to the traditional Chinese concept of the 5 elements that make up the entire universe.
What is the Olympic Torch made from?

When the Central Junta fell to the French, numerous new Juntas appeared all across the Americas, eventually resulting in a chain of newly independent countries stretching from Argentina and Chile in the south, to Mexico in the north. After the death of the king Ferdinand VII, in 1833, only Cuba and Puerto Rico remained under Spanish rule, until the Spanish–American War in 1898. Unlike the Spanish, the Portuguese did not divide their colonial territory in America. The captaincies they created were subdued to a centralized administration in Salvador (later relocated to Rio de Janeiro) which reported directly to the Portuguese Crown until its independence in 1822, becoming the Empire of Brazil.
Who did the central Junta fall to?
the French

The investigation of the transmitted signals started immediately after the launch of Compass -M1 on 14 April 2007. Soon after in June 2007, engineers at CNES reported the spectrum and structure of the signals. A month later, researchers from Stanford University reported the complete decoding of the “I” signals components. The knowledge of the codes allowed a group of engineers at Septentrio to build the COMPASS receiver and report tracking and multipath characteristics of the “I” signals on E2 and E5B.
What was the purpose of building the COMPASS receiver?
report tracking and multipath characteristics of the “I” signals on E2 and E5B
