If you worked at the Hitachi G1 Tower, I'm sure one day will be enough to satisfy your need for speed. Roller coasters? Easy as pie. A formula 1 race car ride? You could do it sleeping. The world's fastest elevator? Now that's a ride.
The Hitachi G1 Tower will be home to an elevator research facility that will be doing just that -- testing the fastest elevator. With a top speed of 3,500 feet per minute, that's pretty darn fast.
