SlikeSpitfire Oct 15, Oct 22, You're welcome, SlikesSpitfire. One of the companies that were given contract by U. In , he was working on powered radar set when he noticed that a chocolate bar that he had in his pocket was melting.
He exposed popcorns to microwaves and they popped, he tried the whole egg and it exploded. Then he attached a high density electromagnetic field generator to an enclosed metal box and experimented on food that way which allowed for controlled and safe experimentation.
Microwave cooking oven was patented on October 8, with the one of the first prototypes placed at a Boston restaurant for testing. The first public was in January in a Speedy Weeny vending machine in Grand Central Terminal which sold freshly cooked hot dogs. The first commercially available microwave oven also appeared in It was made by Raytheon, it was called Radarange had 1.
In time price fell. In the s, Litton Company developed a new configuration of the microwave: the short, wide shape that is now common, with a magnetron feed that could survive a no-load condition when there is nothing in the oven to absorb microwaves which made microwave oven safer. This helped rapid growth of the market for home microwave ovens.
A microwave oven is a kitchen appliance that is in nearly every U. Bureau of Labor Statistics. With the touch of a couple of buttons, this ubiquitous device can boil water, reheat leftovers, pop popcorn or defrost frozen meats in mere minutes. The microwave oven was invented at the end of World War II. Yet it took awhile for them to catch on. At first they were too big and expensive, and people didn't trust them because of the radiation they use.
Eventually, technology improved and fears faded. By the s, Americans named the microwave oven as the No. Percy LeBaron Spencer was a self-taught engineer who had never finished grammar school, according to the Southwest Museum of Engineering, Communication and Computation. While at the Raytheon Corp. In , he devised a more efficient way to manufacture them.
His innovation allowed production to rise from 17 per day to over 2, per day. Intrigued, Spencer tested other foods, including popcorn kernels, and noticed that they all popped. He put an egg near the magnetron and watched as it started to shake and then explode. Spencer realized that the foods had been exposed to low-density microwave energy, according to Gallawa.
He next built a metal box and fed microwave power into it. The energy entered the box but could not escape — microwaves do not pass through metal. Spencer discovered that microwaves could cook food faster than convention ovens that used heat. He filed a patent application in Spencer went on to receive patents throughout his career, according to the National Inventors Hall of Fame. He died in The first commercial microwave oven was tested in a Boston restaurant in Later that year, Raytheon introduced the Radarange It stood 5.
