Thin stamped construction is cheap, but can still be fitted with sleeving on the live (active and neutral) pins like UK & europlug, but not US plugs. This prevents objects or fingers getting to live pins on a partially inserted plug.
Industry has agreed that leads exit either straight out, or down-and-right, so there is no conflict for horizontal or vertical sockets. Sockets are universally installed earth-down.
No. They provide phase shift to give the single-phase induction motors a rotating rather than oscillating magnetic field. They charge and discharge 100/120 times per second depending on grid frequency.
They do not cover inrush current, and would need to be orders of magnitude bigger and a different topology to do so.
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.
You're wrong in terms of long distance power lines being mostly copper, but this does seem a lot like fossil fuel propaganda.
Motors, generators, and transformers can be built using aluminium; they're just a bit bulkier and less efficient. Very common practice.
It looks like CCA might be making its way back into house wiring in the near future, with much lower risks than the 70s aluminium scare.
The big thing is that batteries really should be a last resort, behind demand response (using power when it is available, rather than storing it for later), long distance transmission, and public transport instead of private vehicles.
That's incorrect. Aluminium is about 30% worse by volume than copper, meaning you need to go up a size. What stopped it being used for houses was that the terminations weren't good enough, because aluminium has different thermal expansion and corrosion properties, plus they were using much worse alloys. That's now mostly fixed and if you're in the US, there's a very good chance that your service main is aluminium, and there's talk of allowing copper-clad aluminium (CCA) for subcircuit wiring.
Per mass, aluminium is a better conductor, which is why it's almost exclusively used overhead and in pretty significant volumes underground. The power grids were built on ACSR.
They've been deporting those who are there legally too.
With an insufficient workforce, pay rates going up isn't necessarily enough to get you workers. Moving regions to get a new job isn't usually cheap or fast.
I don't know if the previous pay rates were illegally low (the US's definition of illegally low is itself low), but that doesn't necessarily mean that they couldn't & wouldn't pay ~$20-30/h if there were workers available.
Going from a labour-cheap world to a labour-expensive world also implies that people want to increase mechanisation and automation, and that's not cheap or fast either.
In a lot of the world, a school bus is a normal city bus that gets "school" signs put on the front and back, and runs a specific route. There's not much point in maintaining a dedicated fleet.
It would have to be in a single district; attempting multiple would definitely fail.
NZ has had a number of individual electorates where the Greens* won the seat, Labour came second, and National 3rd. With a sufficiently left-wing area and a galvanised base, it's possible.
Note: NZ greens definitely are not the same as the US Russian plants.
It is possible for a third party to arise in FPTP elections, but it's certainly not common or easy. The UK has a bunch; NZ had a couple before moving to MMP; I think Australia has some.
It usually requires a competent and well-known politician storming out of their party for ideological differences, but being locally popular enough to win their seat as an independent or new party.

Reasonably compact.
