Burj Khalifa, Dubai - The World's Tallest Building (as of Sept, 2010)
Here's a video compilation of the world's tallest building from a recent trip to Dubai, UAE. Fast facts:

--Weighs 500,000 tons (and has already sunk 2.4 in / pilings are 150 ft down)
--It has 164 floors
--It can be seen 90 km/60 mi away (on a clear day)
--The temperature on average is 10 C cooler at the top vs. the bottom
--It's designed to sway 6 ft at the top in high winds
--The A/C required is the equivalent of melting 12,500 tons of ice A DAY
--The observation deck is on the 124th floor (but NOT the tallest ob deck in the world...that still goes to the CN Tower and Shanghai WTC)
--The highest recorded wind speeds at the top: 198 km/h (123 mph)
--It was built with 28,601 panes of glass.
