How are microwaves a spin off of military technology?

When RADAR was first invented, in the 1930s, it didn't work very well because high directional accuracy required either a gigantic antenna or very short wave-lengths. Vacuum tubes had great difficulty in producing wavelengths below about 1.5 meters. In 1940 two men named Randall and Boot, working at Birmingham University in England, invented a device called a Resonant Anode Cavity Magnetron which could generate wavelengths about a thousand times shorter. Now called just a magnetron, this transformed RADAR; it has also transformed cooking, because there is at least one in almost every kitchen, inside the microwave oven.

What energy powers a microwave?

Microwaves use electricity as their source of energy. The electrical energy powers the magnetron inside the microwave, which generates microwave radiation. This radiation heats and cooks the food inside the microwave.
