- Comment on Geologists doubt Earth has the amount of copper needed to develop the entire world 1 week ago:
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.
- Comment on Geologists doubt Earth has the amount of copper needed to develop the entire world 1 week ago:
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.
- Comment on Google and Adobe appear to be abusing copyright to silence a whistleblower's video 5 weeks ago:
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 incompetence.

Do you remember where you played it?
It sounds/looks a little like some of the stuff from bontegames.
- Comment on OpenWrt Two will be a higher-performance router with 10 Gigabit LAN and WiFi 7 support - Liliputing 2 months ago:
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.

- Comment on It took 68 years for the world to reach 1 terawatt of solar PV capacity. It took just two years to double it | RenewEconomy 6 months ago:
Indeed.
In addition, there’s a lot of consumption that was non-electric (e.g. transport, heating) that is moving to electric. Most of the increased grid consumption is not new consumption, it’s consumption that was previously direct fossil fuels.
The exception is basically bitcoin and AI, plus electrification of underdeveloped areas.
- Comment on xkcd #3001: Temperature Scales 7 months ago:
Converting between Kelvin and Celsius is simple addition; converting between Rankine and Fahrenheit is simple addition. Converting between the two groups requires multiplication, and pre calculator, that’s notably harder.
Also, all your kJ/kg/°C or BTU/lb/°F tables and factors are identical when you swap to referencing absolute zero. If you change to the other unit system, all that goes out the window.
- Comment on Clevo reseller wants get coreboot ported, ends up throwing a temper tantrum and banning Germany, Texas and AMD over unsatisfactory experience 7 months ago:
I feel dumber having read that.
Banning a whole country because you disliked a company?
Dealing with stuff that’s ‘almost working’ is often harder than starting from scratch; ask any tradesperson.
They also apparently cannot get their heads around the fact that people might give you a discount if you advertise their brand. Ad-supported pricing has been around for a long time; it’s not some voodoo.

The other scores seem to be more about inherent cursedness, not simply ‘there is a far better option’.
- Comment on xkcd #3001: Temperature Scales 7 months ago:
I am very surprised that Rankine gets such a high cursedness score. Isn’t it just the same as Kelvin but based on Fahrenheit instead of Celsius?
- Comment on Intuit possibly succumbs to the Streisand effect 7 months ago:
Until the day comes that I get a letter in the mail from the government saying, “Here’s how much you paid in taxes, if you’re cool with that then please disregard”, I will not be satisfied.
NZ does that. More accurately, they email you to tell you that there’s a letter available online - I don’t think they send physical mail by default.
Then they pay any refund straight into your nominated bank account.
- Comment on World Conker Championships men's winner cleared of cheating | UK News 7 months ago:
"We are gentlemen at the World Conker Championships and we don’t cheat. I’ve been playing and practising for decades. That’s how I won.
“I admit I had the steel conker in my pocket, but I didn’t play with it. I show it to people as a joke, but I won’t be bringing it again.”
Mr Jakins won the men’s competition but lost in the overall final to women’s champion Kelci Banschbach, originally from the United States, who only took up the game last year when she moved to Suffolk.
Hmm.
- Comment on Why did my bus driver want me to not pay the fare and instead just "TAKE A SEAT!!!" 7 months ago:
If we knew what city/route/service and day, we might be able to get a better idea.
-
Sometimes operators declare a ‘fare holiday’ when everyone rides free, usually as compensation for some major fuckup previously, or for some other PR stunt. Metlink in Wellington doesn’t charge on Christmas Eve, Christmas Day, or New Year’s Eve.
-
Operators sometimes half-strike and refuse to collect fares.
-
The specific route, service, or time of day might be free.
-
It’s an express service that you can’t pay cash on (only fare cards) and it’s easier/nicer to tell you to ride for free than to tell you to get the next bus because they don’t take cash.
-
You might be part of some group (youth, students, elderly) that doesn’t have to pay.
-
Something is broken and they can’t collect fares.
-
They don’t want to deal with the big banknote you had.
