Design
Nikola Tesla
The design of kettle underwent several changes as technology improved. The primitive kettle was basically a container that was held over an open fire to heat the liquids within.
In the 18th century, the industrial revolution which spurred several inventions such as the AC generator by Nikola Tesla enabled the creation of devices that can be powered by electricity and kettles were one of these devices. The availability of an alternative power source meant that kettles were no longer needed to be held above an open fire.
The very first electricity kettle was developed in 1891, in Chicago by the Carpenter Electricity Company of United States where the heating element, powered by electricity was placed under the kettle, where the open fire was supposed to be. Due to the separation of the heating element and the kettle, the energy efficiency was poor and thus, it required 12 minutes to heat the water to a boil.
The next change for kettles’ design came in 1922, where The Swan Company created a kettle in which the heating element was, sealed in a metal tube was placed within the container. This decreased the time needed to boil the water and soon after, many other companies started to follow this design.

Russell Hobbs Design
In 1955, Russell Hobbs was credited for his innovation of the automatic kettle which was able to turn itself off once the required boiling point of the water has reached.
The next major improvement of the design came in the 1980s in the form of cordless kettle. This kettle can be lifted off its base, allowing the user to pour the boiling water. This design have other benefits as well such as preventing electrocution when water and electricity come into contact with one another and also the added convenience of being able to carry the kettle to any distance, and hence, this makes the kettle the popular kitchen appliance we have today.
