Some might find this interesting.
52 years ago I was worked for a little company. There was an oven in the assembly room. I ask Ed the owner what it was. This oven looked like a regular home oven. Ed said it had an electron tube in it.
I ask what’s it for.
Ed you can heat water in it very fast. You can cook a chicken in 5 minutes.
I ask why don’t someone make them.
Ed they would be so expensive no one could buy them.
I found out later it was the original prototype microwave oven.
30 + years ago I was doing work for a company in Raleigh Nc. They developed a microwave oven that would heat a price of ceramic 4 inches in diameter and 4 inches long to white hot in 1 minuets. I had a 50,000 watts tube in it. A regular microwave oven will only heat water but with the right frequency they will heat ceramic. At that time our government was building a super collider in Texas and needed to coat the inside with diamond. This microwave oven was a part of that. The collider was cancelled and the company went bankrupt in a few years.
