Almost all the homes of today have a microwave oven. It saves a lot of time and most importantly your efforts. The device can offer you an array of dishes with the touch of a few control buttons. It was invented during the times of the second world war. But many were apprehensive owing to the extensive and expensive design of the microwave. Not many were inclined to use the device because of the radiation that was involved. But today, the fears have faded away with technological advancements. Many households currently have more than a microwave oven to streamline their lives.
There is an interesting history associated with the invention of this
ubiquitous gadget. A skilled engineer, Percy LeBaron Spencer was working on vacuum tubes and magnetrons to produce microwave radiations. They were intended to be utilized in radar systems. Spencer was found to be efficient in producing more emissions. One day during his lab sessions, chocolate was dropped accidentally onto the magnetron which began to melt. The curious Spencer wanted to extend his experiment sessions. He began testing the other food items. The popcorn kernels started to pop, and the eggs began to explode too. Spencer made a quick interpretation.
The brilliant chap soon found out that the low-density microwave energy did cook the foods. Spencer was ready for his next set of experiments. He constructed a small metallic box and released microwave radiations into it. The inquisitive mind found that foods were cooked faster. Soon, in 1945 he developed a patent for his invention. After that, Spencer had acquired 150 patents as per the reports of the National Inventors Hall of Fame. During 1947, one of the restaurants in Boston tested the commercial microwave oven. With time, the popularity grew, and today many food establishments make use of the indispensable microwave ovens for different functions.
