Noble gases are frequently used in tubes for many purposes, from lighting to switching. Pure noble gases are employed in switching tubes. Noble-gas-filled thyratrons have better electrical parameters than mercury-based ones.
The first electric motor able to turn machinery was built by William Sturgeon in 1832. In 1821, Michael Faraday built a machine that made a piece of metal move due to the flow of electricity. Although the amount of motion was small, this was the first published design of an electric motor. All subsequent developments in the use of electricity to make motors work came out of this invention. The first electric motor able to turn machinery was built by William Sturgeon in 1832.
First Crude Electric Vehicle Is Developed. Around 1832, Robert Anderson develops the first crude electric vehicle, but it isn't until the 1870s or later that electric cars become practical. Pictured here is an electric vehicle built by an English inventor in 1884. Photo courtesy of the Smithsonian.
