Did you know that the microwave oven wasn’t actually invented until after World War II? In fact, it was developed by two scientists who were working on radar technology for the military. They discovered that if they directed microwaves at food, it would heat up quickly. And so, the microwave oven was born! This blog post will explore the fascinating history of this kitchen appliance and how it has evolved over the years.
Microwave ovens have come a long way since they were first invented. In the early days, they were large and expensive, and only restaurants and hospitals could afford to use them. But over time, the technology has become more affordable and portable, so now almost everyone can enjoy the convenience of a microwave oven.

Yet I still have to fry eggs in a pan.
You don’t want those in a microwave
“Yes, hard for me to remember exactly, but our first was labelled “Radar Range”
Probably an Amana Radar Range
“they were so heavy it was crazy!!”
They were lined with lead...
Now they claim we don’t need the lead lining? They say the holes are too small for the waves to escape through. I would feel safer with the lead. :)
I do it all the time. But OUTSIDE... lol

Wasn’t an AWACS plane and probably not microwaves, but we had a grad student working for us and when he got his PHD we hired him on as a permanent. His first assignment was to solve a problem of the associated with the presidential plane. At random times the fire suppression system would flush the plane when it was in the maintenance hanger for maintenance. Turned out that the radio maintenance people were required to not operate the radio equipment in the hanger. Some how they skipped over that page in the manual and caused a number of expensive and messy incidents.
Forget the lead. There are other metals that are cheaper, lighter, and better electric conductors (which you want for radio frequency shielding) than lead.
I have had a microwave in my kitchen for more than 40 years. While I use my microwave often it is just for reheating leftovers, making popcorn and making frozen convenience foods. For actual made from scratch foods, I find my air fryer and digital pressure cooker to be better choices. My least used kitchen appliance these days is my stove.
You need to read up on ionizing and non-ionizing radiation.
Big difference.
I understand that too. I just question their claim that the wave length is too long to escape through the window grate holes. The concept that they are ALL bounced back without escaping is a bit questionable to me.
“I had always heard the chocolate bar story.
Is that an urban legend?”
The 1930’s had a demonstration of cooking food using radio wave.
Heat therapy with radio waves was done in the 1920’s.
My wife & I bought a microwave in the 70’s. They offered free microwave cooking classes.
After about a month we attended our first class. They went around the room asking couples what they had cooked with their new microwaves. Half the class hadn’t done anything with theirs. The rest had warmed up water or something like that.
We were the last couple to respond. We had cooked a turkey with stuffing and a casserole. It turned out delicious. The teacher said we should be teaching the class.
