The Bubbleator was a large, bubble-shaped hydraulic elevator with transparent acrylic glass walls operated from an elevated chair built for the 1962 World's Fair in Seattle. These transparent walls gave the illusion of looking through an actual 'soap bubble' by refracting light to obtain a rainbow-like effect for the riders inside.
The elevators in a skyscraper are not simply a necessary utility like running water and electricity, but are in fact closely related to the design of the whole structure. A taller building requires more elevators to service the additional floors, but the elevator shafts consume valuable floor space.

Thus, the local elevators can be stacked within the same elevator shaft. [78] Located on the 44th and 78th floors of each tower, the sky lobbies enabled the elevators to be used efficiently, while also increasing the amount of usable space on each floor from 62 to 75 percent by reducing the number of required elevator shafts.

These tendons are required since the eastern end support is both much lighter than the western counterweight and the soil conditions are radically different at each end, the western end being founded in bedrock shale while the eastern end, with vertical supports driven to bedrock, is mostly contained within softer mud deposits, which respond ...
Unlike a standard elevator, it can go up tilted grades. It can be used for both residential and commercial purposes. The purpose of inclined elevators is to provide accessibility to steep hillsides and inclines at minimal effort to the user. An inclined elevator is a form of cable railway.
The basic principle in these games is simple -- match three or more of the same bubble by shooting new ones from the bottom of the screen to the rows towards the top.
A moving elevator car forces the air in front of it out of the shaft and pulls air into the shaft behind it with the effect most apparent in elevator systems with a fast moving car in a single shaft. This means that in a fire a moving elevator may push smoke into lower floors. [4] The piston effect is used in tunnel ventilation.
