In 1802, Humphry Davy invented the first electric light. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. And while it produced light, it didn’t produce it for long and was much too bright for practical use.

Many working fluids have been use for such purposes.
In 1834, the first working vapor-compression refrigeration system was built. The first commercial ice-making machine was invented in 1854. In 1913, refrigerators for home use were introduce. Frigidaire introduced the first self-contained unit of refrigerators in 1923.
