11·1 month agoWhat 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.

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.
Google has removed the video through an automated process without talking to the owner of the channel or verifying who owns the video in the first place.
Honestly sounds like Hanlon’s Razor on Google’s part. No collusion necessary, just can’t be bothered to maintain/staff an actual effective system.
Do you remember where you played it?
It sounds/looks a little like some of the stuff from bontegames.
6·3 months agoIt’s heavily dependant on the plastic type. PET bottles are pretty good.
Even if it’s not recycled, it’s still far better to landfill or burn it than have it hit waterways.
That’s not bad pricing wise. There’s very very little prosumer gear that’s multi gigabit and it’s all much higher price, or it’s just a PC with several NICs.
If and when we move to hyperfibre this is going to be pretty high up on the list.
Lots of places also have variable limit signs that get updated based on traffic, accidents etc.
Here in NZ those seem to all be marked on the speed limit maps as 100km/h even if in some places the signs never go above 80.
Ngauranga Gorge is one such location and I believe has the country’s highest grossing speed camera.
The question seems open to interpretation (which is bad for surveys like this).
If I visit a location that was the site of a mass shooting a few years later, have I been “physically present on the scene of a mass shooting”?
I think you could reasonably answer yes: you’ve been to the physical place where it happened, even if not at the time it happened.
8·5 months agoOh, I’ve had the name for a lot longer than that.
As Someone Somewhere, I urge you to post more.
Flags shall be flown from a balloon tethered to the top of the flagpole.
Normally I’d be against the waste of helium but I’m prepared to make an exception.
603 for maglevs, 574.8 for steel rail, set in France in 2007 by a hotted up, modified TGV.
China holds the record for a stock train at 487, set in 2010.
(all per Wikipedia)
It looks like the article might be implying that they will be the fastest trains operating in revenue service when they enter service, but that surely needs to be demonstrated with a production train in revenue service.
1·6 months agoNZ law just says it has to be adequate for the intended purpose: https://www.legislation.govt.nz/act/public/2002/0035/latest/whole.html#DLM154837
(1) Subject to subsection (2), a legal requirement for a signature other than a witness’ signature is met by means of an electronic signature if the electronic signature—
(a) adequately identifies the signatory and adequately indicates the signatory’s approval of the information to which the signature relates; and
(b) is as reliable as is appropriate given the purpose for which, and the circumstances in which, the signature is required.
(2) A legal requirement for a signature that relates to information legally required to be given to a person is met by means of an electronic signature only if that person consents to receiving the electronic signature.
3·7 months ago98% of it seems to be 4.
If it has navigation lights and is on approach to a runway, it’s probably an airliner, even if you can’t see everything because it’s dark.
