Evolution of the Microwave

  • Creation

    Creation
    The microwave was patented by Raytheon. Percy Spencer of Raytheon discovered a chocolate bar melted in his pocket during his work with radar sets. He then experimented with corn and an egg realizing he could cook foods. Then he put a electromagnetic generator in a metal box to make the experiment safe, and therefore created the first microwave on accident todayifoundout.com/index.php/2011/08/the-microwave-oven-was-invented-by-accident-by-a-man-who-was-orphaned-and-never-finished-grammar-school/
  • Production of the First Microwave, The Radarange

    Production of the First Microwave, The Radarange
    For people to use Perry Spencer's invention, the engineer's had improve it to be able to use by everyone. Therefore the Engineers at Raytheon started to work and improve the microwave to create the Radarange. However, it was 5 1/2 feet tall, 750 pounds, and $5000. However, due to the price, it was mostly commercial. It had a water-cooled magnetron. *Exact date not given

  • Microwave made available for Domestic Use

    Microwave made available for Domestic Use
    With the help of Raytheon's engineers, Tappan created the first microwave that could be used in houses. It was 5 and a half feet tall and 750 pounds. It also featured a water-cooled magnetron. *Exact date not given

  • Addition of the Air-Cooled System

    Addition of the Air-Cooled System
    Because the water cooled system was not practical for a household microwave, Tappan engineers add an air- cooled system into the microwave. *Exact day not given

  • Radiation Control for Health and Safety Act

    Radiation Control for Health and Safety Act
    It was passed because of the results from radiation tests through experimentation by the U.S. Department of Health, Education, and Welfare, which said the microwave ovens leaked microwaves. http://www.encyclopedia.com/topic/microwave_oven.aspx
  • The Change of Microwave Ovens for Safety

    The Change of Microwave Ovens for Safety
    Due to the Radiation Control for Health and Safety Act, the standards and regulations were published by the government, so companies got to work to abide by these regulations.
