The Evolution of Elevators: From Ancient Times to Modern Technology
TLDR Elevators were not commonly used in ancient and medieval times due to low buildings, high costs, lack of energy sources, and safety concerns. However, with the development of steam engines and the invention of the permanent counterweight and safety elevator in the 19th century, elevators became feasible for human transportation. Today, elevator technology has evolved to include features such as express elevators and multiple elevator shafts, making them one of the safest modes of transportation.
Timestamped Summary
00:00
The elevator is an invention that has been known forever but only recently became practical and useful.
01:40
