> My father was a radar officer in WWII, and recalled warming his hands on cold British mornings in front of the beam emitted by a "magnetron" inside his primitive radar transmitter. Then he went back to work detecting Nazi aircraft. But, it is a short distance from warming to cooking- in 1946 engineers at the military contractor Raytheon noticed microwaves could not only warm, they could heat and cook food.

In the 1990s I was a contractor at DRA Malvern in the UK, which was one of the successor organisations to the WW2 radar research establishments. The greybeards I encountered always felt that they had invented microwave cooking even if Raytheon got the credit later. Sausages cooked using the lab magnetrons, they said, although unfortunately there were no photographs.

The future of cooking was something that famous futurist Arthur C Clarke got wrong. He might have predicted geostationary communications satellites but in his short story The Sentinel - which was the inspiration for the film/book 2001 - the crew of a small lunar rover fry their sausages in a conventional frying pan.
