Reply to comment by slam525i in 30 minutes of car preheating in sub-zero conditions produces as much particulate emissions as driving 97km in a gasoline car, or 20km in a diesel car “These findings do not suggest to stop preheating cars; instead, we could reduce the emissions by using similar methods that are in place for engine” by giuliomagnifico
I would guess the study is on fuel-driven pre-heaters, not pre-heaters driven by mains electricity.

The most undercommunicated thing about space is the size of emptiness between the stars and how far away everything is from everything else.
Think of anything a lightyear away as omg-so-incredibly-far-away-it-is. That makes this black hole super-duper-omg-so-incredibly-far-away-it-is.
