Microwave oven
In 1947, Raytheon built the "Radarange", the first commercially available microwave oven. It was almost tall, weighed and cost about US$5,000 ($ in dollars) each. It consumed 3 kilowatts, about three times as much as today's microwave ovens, and was water-cooled. The name was the winning entry in an employee contest. An early Radarange was installed (and remains) in the galley of the nuclear-powered passenger/cargo ship NS "Savannah". An early commercial model introduced in 1954 consumed 1.6 kilowatts and sold for US$2,000 to US$3,000 ($ to $ in dollars). Raytheon licensed its technology to the Tappan Stove company of Mansfield, Ohio in 1952. They tried to market a large 220 volt wall unit as a home microwave oven in 1955 for a price of US$1,295 ($ in dollars), but it did not sell well.
Wonder Pot
The Wonder Pot retained its popularity through the 1970s, especially among new immigrants who did not have ovens. During its heyday, the Wonder Pot spawned its own bestselling cookbook. The introduction of the microwave oven and a national desire to dissociate with the austerity mentality put an end to its widespread use. However, the Wonder Pot is still used by Israeli Haredi families for baking kugels, and it is also popular in this sector on the holiday of Passover for those who do not have a kosher-for-Passover oven.
