Despite raising cranes, helicopters, trucks and tractors in bulk, building a pyramid as the Great Pyramid of Giza today remains extremely difficult. In the eyes of many people, the pyramid was built 4500 years ago was like a miracle, or even related to the hands of aliens. However, recently emerged a hypothesis about the Great Pyramid was built from the building, through a pulley system internally very sophisticated and scientific. If according to plan, build perfect, we will be able to recreate Wonder of the ancient world at the cost of up to $ 5 billion. The construction of a pyramid as the Great Pyramids of Giza today remains extremely difficult. Why is a figure so terrible? First, let's look at the figures of the Great Pyramid. Giza total length of 756 feet on each side, 481 feet high and consists of 2.3 million stone blocks, each block weighs approximately 3 tons. Thus it is the total weight of up to 6.5 million tons. Legend has it that the whole project was completed in just 20 years, meaning that each stone was transported and put in its place in just 5 minutes (if the construction is taking place 24 / 24h ). Progress which obviously requires the labor of thousands of people. The previous hypotheses about the ancient Egyptians used a pulley system to build Giza outside many loopholes such as a pulley will be longer than a mile enough strength to pull the heavy stones. In addition, it will need a heavy rock on double pyramid to balance. Architect Jean-Pierre Houdin believes that only a third of the height of Giza, from the bottom up, is built from the pulley blocks apart. With 33% of the remaining work, the Egyptians will heighten up through a pulley system in sophistication. Houdin has collaborated with 3D graphics company Dassault Systems to develop a virtual model of the building process above. At the same time, a group of scholars at the University of Laval (Quebec) is intended infrared scanning to determine whether or not the existence of a network of pulleys inside the Great Pyramid. There are two big differences in the Pyramid building that day and now, according to Houdin. First, instead of using the power of rock to pull the pulley, now we will use the tool motor. Second, to the highest part of the pyramid (about 10-15m top), you can use a small crane. With the help of modern facilities and helicopters, one of the modern Giza will require capacity of approximately 1500-2000 people who work uninterrupted in 5 years. The total estimated cost of up to $ 5 billion. For comparison, One World Trade Center Building 1776 feet high in the center of Manhattan (USA) and construction costs only about $ 4 billion.
