141st floor please

In an incredible (an ongoing) feat of engineering, Dubai in the United Arab Emirates has built the world's tallest building. Not only is this building the new tallest building in the world, they still have nearly another year of building to go which pretty much guarantees this will be the tallest building for quite some time. Although the news.com article speaks for itself, some highlights of the Burj Dubai building include:

• On July 21, construction reached 1,680 feet on the 141st floor (now 13 feet above the former record holder, Tapei 101 in Taiwan, which is 1,667 feet above the ground)
• Burj Dubai is the tallest building now, and according to the official site, it's nowhere near finished. The final height and number of stories are a secret.
• When finished, the building will be comprised of 330,000 cubic meters of concrete, 39,000 metric tons of steel rebar, and 142,000 square meters of glass--which will take 22 million man hours to complete.
• 66 elevators and escalators, which will be the longest elevators in the world and will travel at more than 2o miles per hour
