Here’s what was important this week…
More than you probably ever wanted to know about refrigerators and refrigeration:
Oh how I wish this had come true:
“All mechanical fridges work by controlling the vaporisation and condensation of a liquid called a refrigerant. Most fridges today do this control with a special electric-power pump called a compressor, but there’s also the technique of absorption, which is kicked off by a gas-fuelled flame. The fridge’s hum wasn’t inevitable.”
I have somewhat of an aversion to background humming noises, like that of a refrigerator, central air system, fluorescent lights, or washing machines.
