But physics doesn't change much in 6 years, particularly where the efficiency of microwave ovens is involved. If you Google "microwave oven efficiency", this is the #4 hit and the first three items don't provide any useful information regarding efficiency - hence the post. Google makes this a...

Microwave ovens are not as efficient as one might think. I conducted experiments on two ovens. #1 was built in 1987 and #2 is a built-in from 2000. Input power was net magnetron input measured using a Kill A Watt and subtracting off idle power (lamps, blower, turn table) by measuring power when...
