I believe that would exclude Canada, Aus, and NZ which are pretty firmly considered first world.

Work pants with pockets for built in kneepads.
If you do any kind of maintenance or trades, you're probably kneeling a lot.
Knee pads make it so much more comfortable but they're usually annoying and tight, even painful.
Putting them in the trousers makes it a non issue.
Biofuels/ethanol/SAF are much the same; often derived from corn.
In many cases, the oil/gas/electricity used for harvesting, processing, cracking etc. is actually comparable to or exceeds the carbon released by simply drilling for and burning the oil in the first place.

IIRC 'point blank' means no need to adjust for bullet drop due to gravity. This is well within that.
Brick does really badly in earthquakes, at least without major reinforcing. 'Unreinforced masonry' can be fatal pretty easily.
Brick veneer over timber framing can be a thing.
"Stop getting worse" is a pretty major improvement. And yes, trees work as carbon sequestration.
Most (all?) CCS is not grabbing random carbon from the atmosphere. It's pulling it out of smokestacks so you can keep burning fuel while claiming it's green. It is not net negative even if working as intended.
It's nearly midnight here. Still dumb.
New Zealand!
What I mean is that the bulk of current copper wiring goes towards distribution and consumption, not generation.
Yes, but big batteries everywhere is going to effect that if there's copper in lithium batteries, and apparently there is.
This isn't a big thing. This is a constant thing in every system. It's the push and pull between efficiency and resiliency. More storage capacity is less efficient when things are going well, but is more resilient and adaptable when they're not.
Excess storage capacity, sure.
But inflating the base battery capacity to cover people having showers at 5pm because it's easier than storage water heaters and time/remote controls is stupid. You can reduce the base need for batteries by reducing the need for electricity in the first place and reducing the use of vehicles that need to carry batteries in place of e.g. overhead catenary.

The issue with aviation hydrogen is... well, lots.
Fuel cells are heavy and direct combustion is inefficient and tougher than burning kerosene.
Aircraft typically use the wing structural members as the fuel tank walls. Both cryogenic and pressurised options make that a non-starter.
Lower density means much bigger tanks.
Self-vapourising fuel is a major crash issue.
Round trip efficiency for H2 is still terrible.
Plants may not be particularly efficient per km^2 but arable land isn't actually that hugely scarce.
Reducing aviation is really the only thing that's actually going to work.
