Why The First Commercial Microwave Oven Was The Size Of A Refrigerator And Cost As Much As A House

Why the first commercial microwave oven was the size of a refrigerator and cost as much as a house. Sources: Percy Spencer (1945): The magnetron was a heavy, water-cooled vacuum tube built for detection, not cooking. Raytheon Company (1947): Early models required external water lines for cooling, necessitating a refrigerator-sized chassis. Toshiba (1962): The introduction of the integrated magnetron allowed for the first countertop model, the RE-101. Amana (1967): High manufacturing costs and low sales volume kept early consumer microwaves expensive and bulky. Imagine a crowded wartime radar station in 1942, the air hums with the intense heat of high-power electronics. You are standing in Boston, inside the Raytheon Company facility in 1947. And in 1947, that meant water. You stand on the polished tile of a 1965 appliance showroom floor. You look down at the RE-101 sitting heavy on the display. This machine was built by Toshiba in Japan back in 1962. The introduction of the integrated magnetron allowed for the first countertop model, the RE-101. It draws 1000 watts of electricity from the wall, that is not a trivial amount of power. A written fact-check was run on this script before it was recorded.
