I remember reading about the fight between polished aluminum planes and painted. The paint adds weight, and thus increases fuel consumption, but the paint lowers maintenance costs.
A dirty airplane can absolutely burn a noticeably larger amount of fuel.
A car is operating at much lower speeds, generally, so the effect is probably much less.

NASA contracts out missions, they don't really do missions in-house. SpaceX is currently winning the launch and visit ISS missions by a mile. Competition like Boeing is more expensive and less reliable.

$500 hammer was actually a set of hammer, shovel, and pick. It had to be non-magnetic, non-sparking, yet durable enough for work. Intended use was for digging out old unstable explosives that the government had let sit around for far too long after WWII.

Pencil that could write in space - standard pencils use graphite, and shed graphite dust when used. Graphite is carbon, it is both conductive and flammable as a powder. Can one see why that might be bad in zero g constrained atmospheres?
The Fisher space pen was developed by Fisher, on his dime, and subsequently sold to both space agencies, US and Russia.

Around 1990, I worked for a couple months on an embedded device that had an 80186 and a megabyte of RAM. At one point, I had access to a huge pile of 1MB SIMMs and took a stack home for the evening and using memory boards that allowed you to stack up to 8 of them into one SIMM slot in your computer to figure out just how little RAM Windows NT 3.5 really needed to boot. It booted successfully with 12MB of RAM. It really wasn't usable, but it did boot up. Nowadays, Windows is probably only marginally usable with 12GB of RAM.
