TROLL Science: Mobile phone battery charging[edit]

Possibly a new fad to dupe ignorant people. Placing a flat battery (of any sort, but typically mobilephone Lithium Polymer types) does not charge the battery when the oven is operating.. It may produce an explosion and may cuase damage to the device or personal injury. Placing an electrical/electronic device in the microwave containing a discharged (flat) battery of any sort does not recharge the battey within the unit. Not only is it utterly stupid, but will destroy the internal electronics of the device.

1946. 1947.[edit]

Article says, in the lede,

Named the "Radarange", it was first sold in 1946.

Says 1947 later.

wavelength[edit]

There are two frequencies used for microwave ovens. For home use, 2.45GHz. For larger industrial sized, 915MHz. The wavelength has to be smaller than the size of the box, which allows 915MHz for larger units. And yes, it doesn't have much to do with the size or otherwise of water molecules.

Efficiency[edit]

the article says efficiency as low as 50%. I measured my microwave and found 40% i.e. it consumes 1500W for the 600W programme Metroplint (talk) 09:58, 2 April 2024 (UTC)[reply]

Microwave heating is less efficient on fats and sugars than on water because they have a smaller molecular dipole moment[edit]

The article says: Microwave heating is less efficient on fats and sugars than on water because they have a smaller molecular dipole moment, which is true. But those also have a lower heat capacity, so heat up faster. For foods with both water and fats, the fats get hot faster. In addition, they can get hotter than boiling water.
