If you continue to use this site we will assume that you are happy with it. Or not, because there were people who already knew what microwaves could do. They found that baking, griddle-cooking and microwaving produced the lowest losses, while boiling and pressure-cooking were the hardest on antioxidants. They measured the amount of antioxidants present before and after cooking. The popcorn kernels began to pop around the magnetron and inside his lab. Visit our corporate site. Percy LeBaron Spencer was a self-taught engineer who had never finished grammar school, according to the Southwest Museum of Engineering, Communication and Computation. Never underestimate the power of snacks and serendipity. His inventions included the application of microwave energy to medical diathermy and the Radarange oven that cooks food electronically. In 1947, just a year after Spencer's snack food serendipity, the first commercial microwave oven hit the market. It was pretty bulky weighing over 320 kilos which is the equivalent of 700 pounds.

Many microwave ovens today contain sensors that stop themselves when the food has completed cooking, according to SciTech. This particular model, which resembles a thermos, can be used for approximately 30 minutes per charge to heat up to 17 fluid ounces (0.5 liters) at a time. Who Invented Them? But when was the microwave invented? A story this good can't help but change as it's passed down over the years. Here's more on the invention of microwaves.

According to Michalak, at the time Spencer was trying to improve the power level of the magnetron tubes to be used in radar sets. It stood 5.5 feet (1.7 meters) tall, weighed 750 lbs. To put it simply, the energy of the microwave is like rubbing our hands together, but in terms of microwaves, as stated by Norman Krim, a former vice president at Raytheon, they rub molecules of food together for they are vibrating over three thousand million times per second.
