Cops don’t track people down for porch pirating. They aren’t gonna look for a person in a mask kicking doorbells.

If you see a ring door bell, they aren’t hard to kick or rip off the wall.

Actually I’m going to make some informative stickers that happen to cover the camera and sensor of those things. I’ll post them when they’re up.

Hard to say, but they’ve been using resistive radiative cooling In space a long time.

Also a tech ingredients made a neat video about building one and radiating heat out into space from the ground. It was cool to see what happened when it was cloudy and stopped working.

Yeah so there is some confusion here. The are radiators on cars or in houses, but those are more accurately heat exchangers. Then there are things like heat lamps, which are really IR radiators that convert electricity to infrared light that feels hot.

Most of the heat you feel at a camp fire is radiant from the flame, unless you are down wind and feeling some convective heat, but most of that heat goes straight up with the smoke.
