Conservation of Power?
Via Deltoid via Gummo Trotsky.
It took awhile before someone pointed out the obvious.
“Confine a lightbulb inside an infrared barrier (like a globular mirror) and electrically feed one watt to it. After a while, will it be generating the heat of a thousand watt bulb?”
Imagine if a Watt was a unit of power and not energy and you had implied that you could add energy indefinitely to a lightbulb without heating it up, that would be embarrassing.
