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.
Kenwood Chef
Ken Wood began trading as Woodlau Industries Ltd in 1947. His aim was to produce luxury items that would quickly be seen as necessities. He began marketing a toaster and a food mixer with two beaters. The original mixer marketed as "The Kenwood Electric Food Mixer", designed in 1947 was very similar (possibly too similar) to the Sunbeam Mixmaster Model 3, an American mixer made between 1936 and 1939, and he faced serious competition and possibly objection. He completely redesigned the mixer, which was then launched at the Ideal Home Exhibition in London in March 1950. This mixer was no longer just a mixer, as he had added several other functions, and so he called it the Kenwood Electric Chef. It sold for £19 10s. 10d. (£19.54).
