A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

The visible part of the spectrum is likely going to be absorbed somewhere far away from the place you're trying to heat up. Also, I'm not educated enough to tell if there will be further losses of energy
that's only true if you shine it out a very large the window
normally windows cover a quite small fraction of a rooms surface area
but sure, if a few fractions of a percent leave through a window, i guess its technically not a 100% effective space heater, if we define the work as heating only the relevant room.
If it’s in a room the visible radiation will still just heat up the room. If you’re using it outdoors and point it away then yeah you’ll have some waste.
Not sure if visible radiation that leaves through a transparent window will still heat up only inside the room, that what I meant. Probably should have phrased it better
