when did the first electric stove come out
Electric stove Canadian inventor Thomas Ahearn filed patent number no. 39916 in 1892 for an "Electric Oven," a device he probably employed in preparing a meal for an Ottawa hotel that year.[3] Ahearn and Warren Y. Soper were owners of Ottawa's Chaudiere Electric Light and Power Company.[4] The electric stove was showcased at the Chicago World's Fair in 1893, where an electrified model kitchen was shown. Unlike the gas stove, the electrical stove was slow to catch on, partly due to the unfamiliar technology, and the need for cities and towns to be electrified. By the 1930s, the technology had matured and the electrical stove slowly began to replace the gas stove, especially in household kitchens.
Bunsen burner The gas can be natural gas (which is mainly methane) or a liquefied petroleum gas, such as propane, butane, or a mixture of both.
Littlest Pet Shop Introduced in 1992, each set included an action, such as a movable part. Most included magnets or simple mechanisms, such as flapping wings.
Electrolysis of water This technique can be used to make hydrogen fuel (hydrogen gas) and breathable oxygen; though currently most industrial methods make hydrogen fuel from natural gas instead.
Dishwasher Europe's first domestic dishwasher with an electric motor was invented and manufactured by Miele in 1929.[10][11]
Noise pollution Up until the 1970s governments tended to view noise as a "nuisance" rather than an environmental problem.
