Almost every elevator in use today consists of an elaborate contraption of gears, pulleys and shock absorbers. Not only such elevators are bulky and hard to install, they are also more prone to breakdowns. Scientists from Daytona Elevators, a company based in Argentina and Florida, have finally developed a elevator worthy of the 21st century. The elevator (for one person use) is a metre in diameter and almost entirely transparent, providing the passengers with a panoramic view during their ride. Made from lightweight Aluminium and polycarbonate, the installation is a breeze.

The capsule is then lifted by the higher atmospheric pressure at the bottom (not unlike the way a aircraft wing lifts the plane up during flight). While coming down, a valve at the top regulates the air pressure to allow a smooth descent. A braking system ensures smooth stopping of the capsule in case of pressure malfunctions.
The elevator costs between $20,000 and $22,000. It is silent, consumes very little power, and can be installed in small spaces. A video of its operation can be found here (MPEG 3.2MB).
