I could not drive by without taking a picture of a truck with a pair of arc welders on the back. One placed on the right rear one one placed on the left rear corners of the truck. Then there was the microwave oven seemingly mounted at the heart of the bed of the truck with the cord dangling beneath. I thought, which piece of equipment on the back of that truck is most important? As I was hungry, I though, it has to be the microwave oven. One surely cannot heat a frozen burrito with an arc welder quickly and efficiently. Is it current or voltage? No, it is microwaves . . .
