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.

Still tens to maybe low hundreds of microfarads.

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.

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.

I’m not too fond of calling this a ‘tax’. Tax money goes to funding actually useful things. Conservatives want you to think that giving money to the government and throwing it down the toilet are the same thing.

Sounds like they need to move to either ZIF connectors or 48V power; this kind of power over high pin counts isn’t really practical.

There’s a reason electrical codes don’t usually let you use parallel conductors below about 4AWG/60A per conductor.

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.

Fair point, have edited.

Do you remember where you played it?

It sounds/looks a little like some of the stuff from bontegames.

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.

I’m not sure that lossy compression on vectors is strictly impossible.

You can do things like store less colour information and simplify splines so that curves are less complex.

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.

Yeah, add two zeros, especially if using hard drives rather than SSD.

“Greater Canada”.

Everything burns up regardless of size. Big things might not finish burning by the time they hit the ground.

You need either enough thrust to slow you to ~mach 2, or a heat shield to do the same by aerobraking.

It’s called aerobraking for a reason: you’re using friction to turn kinetic energy into heat to slow down, but that heat goes into the air and your heat shield instead of brake pads and rotors.

Oh, I’ve had the name for a lot longer than that.

As Someone Somewhere, I urge you to post more.

People with autism don’t do well with unwritten social rules.

“This is a Nazi salute; don’t do it” seems like about the most expressly taught social rule there is.
