A debate from a podcast Randall Munroe listens to reaches his What If? channel: put a working toaster inside a working freezer, plug in the bread, and see who wins. The math is lopsided before the timer even clicks down — a toaster’s coils put out somewhere around 1,000 watts of heat, while a household freezer’s compressor is straining to pull maybe 150 watts back out. As the video puts it, to a toaster, all our air is cold.
