Who invented the microwave oven?
who invented the microwave over, what year,where was it invented,history of the invention,and use in society.
I knew it was invented accdently but I thought they rays were somehow hooked up to a birds cage, and the person left the house, when he came back the bird was cooked. one day im going to invent the massive wave which would cook anything in a few miliseconds
Cooking food with microwaves was discovered by Percy Spencer while building magnetrons for radar sets at Raytheon. He was working on an active radar set when he noticed a strange sensation, and saw that a peanut candy bar he had in his pocket started to melt. Although he was not the first to notice this phenomenon, as the holder of 120 patents, Spencer was no stranger to discovery and experiment, and realized what was happening. The radar had melted his candy bar with microwaves. The first food to be deliberately cooked with microwaves was popcorn, and the second was an egg (which exploded in the face of one of the experimenters). [citation needed]
On October 8, 1945 Raytheon filed a patent for Spencer’s microwave cooking process and in 1947, the company built the first microwave oven, the Radarange. It was almost 6 feet (1.8 m) tall and weighed 750 pounds (340 kg). It was water-cooled and consumed 3000 watts of power, about three times as much as today’s microwave ovens. An early commercial model introduced in 1954 generated 1600 watts and sold for $2,000 to $3,000. Raytheon licensed its technology to the Tappan Stove company in 1952. They tried to market a large, 220 volt, wall unit as a home microwave oven in 1955 for a price of $1,295, but it did not sell well. In 1965 Raytheon acquired Amana, which introduced the first popular home model, the countertop Radarange in 1967 at a price point of $495.
In the 1960s, Litton bought Studebaker’s Franklin Manufacturing assets, which had been manufacturing magnetrons and building and selling microwave ovens similar to the Radarange. Litton then developed a new configuration of the microwave, the short, wide shape that is now common. The magnetron feed was also unique. This resulted in an oven that could survive a no-load condition indefinitely. The new oven was shown at a trade show in Chicago, and helped begin a rapid growth of the market for home microwave ovens. Sales figures of 40,000 units for the US industry in 1970 grew to one million by 1975. Market penetration in Japan, which had learned to build less expensive units by re-engineering a cheaper magnetron, was more rapid.
A number of other companies joined in the market, and for a time most systems were built by defense contractors, who were the most familiar with the magnetron. Litton was particularly well known in the restaurant business. By the late 1970s the technology had improved to the point where prices were falling rapidly. Formerly found only in large industrial applications, microwave ovens (often referred to informally as simply “microwaves”) were increasingly becoming a standard fixture of most kitchens. The rapidly falling price of microprocessors also helped by adding electronic controls to make the ovens easier to use. By the late 1980s they were almost universal in the US and had taken off in many other parts of the globe. Current estimates hold that nearly 95% of American households have a microwave [citation needed].
Percy Spencer was the inventor
1954 is the date
History: The microwave oven did not come about as a result of someone trying to find a better, faster way to cook. During World War II, two scientists invented the magnetron, a tube that produces microwaves. Installing magnetrons in Britain’s radar system, the microwaves were able to spot Nazi warplanes on their way to bomb the British Isles.
By accident, several years later, it was discovered that microwaves also cook food. Called the Radar Range, the first microwave oven to go on the market was roughly as large and heavy as a refrigerator. The idea of using microwave energy to cook food was accidentally discovered by Percy LeBaron Spencer of the Raytheon Company when he found that radar waves had melted a candy bar in his pocket. Experiments showed that microwave heating could raise the internal temperature of many foods far more rapidly than a conventional oven. Microwave Oven The first Raytheon commercial microwave oven was the 1161 Radarange, which was marketed in 1954. Rated at 1600 watts, it was so large and expensive that it was practical only for restaurant and institutional use.
In 1967, Amana, a division of Raytheon, introduced its domestic Radarange microwave oven, marking the beginning of the use of microwave ovens in home kitchens. Although sales were slow during the first few years, partially due to the oven’s relatively expensive price tag, the concept of quick microwave cooking had arrived. In succeeding years, Litton and a number of other companies joined the countertop microwave oven market. By the end of 1971, the price of countertop units began to decrease and their capabilities were expanded.
Use in society: I have a microwave.
I DID!!!
MY GUESS IS SOMEONE WHO COULDN’T SIT STILL AND WAIT FOR THEIR FOOD TO COOK IN AN OVEN…YOU KNOW…SOMEONE IN A VERY BIG RUSH!
um… ummm.. Oh I know! Someone!:)
why was the micro wave oven made in such a box kinda shape?
Dr. Percy Spencer, an engineer working for the Raytheon Corporation was the inventor of the microwave oven in 1946.
He was testing a megatron, which was a new vaccum tube and he was experimenting with the vaccum tube when he felt a strange sensation at his pocket, where he had placed his candy in it. He took his candy out and found out that it had already melted. This amazes Dr Spencer so much that he decided to do another experiment, but this time, he did not use candy but instead he used some popcorn kernels near the vaccum tube. He stepped back and look closely at the vaccum tube, trying to witness any significant results that would prove his hypothesis. To his amazement, the popcorn kernels popped all over the laboratory, and this conclude his new-found discovery.
This accidental discovery kick-start the production of microwave ovens that we would know and use in the future.
