Pneumatic transportation uses air to move solid objects from one location to another. Pneumatic tubes pull objects through their pipes using the principle of suction. The weight of the object then pushes open the discharge door, allowing the object to fall out.
Description
Cylinder-shaped containers are pulled through tubes by a vacuum or compressed air.
History
In 1810, Englishman George Medhurst invented the pneumatic dispatch tube and the pneumatic railway for the transportation of heavy objects.
Development
George Medhurst's ideas were then developed and used mainly for delivering documents for businesses and government agencies.
Significance
Although it was popular in the past, pneumatic transportation is rarely used today. In America, pneumatic tubes are sometimes used by bank tellers and hospital staffs.
Fun Fact
Pneumatic transportation was developed in the late 19th century, but the basics of pneumatics can be traced back to 100 B.C. or earlier.
