I think my figures are ropey and need a little adjustment. Let's say ~200g+ for the battery option, as I think it's a sub 2Ah 3.7V cell in the mouse. I'm not going to argue it's lower, but I do wonder if that gap isn't as much as you might think.

Sorry, I should have written CO2e, my mistake. But yes, that was what U was getting at.

~250-350g CO2e for a 1.2m cable.

Battery figures tend to be for larger packs, but given they're made of lots of smaller cells...

How much CO2 is emitted by manufacturing batteries?
It depends exactly where and how the battery is made—but when it comes to clean technologies like electric cars and solar power, even the dirtiest batteries emit less CO2 than using no battery at all.

They don't come with chargers, but this got me thinking... eCO2 of a 2mAh Li-ion battery. Worst case, probably 200g. A 5ft USB cable is typically in a similar ball park. Given the cable is typically captive, it's scrapped once the device is retired.
That's not a sales pitch for wireless mice.

Much as I dislike the design feature, it's really quite a manageable one. If you ignore all of the notifications telling you it has low battery for weeks, and it goes flat, plug it in for 2-3 minutes, then use it for the rest of the day.

Is it even art of war? I thought that normally gets attributed to Napoleon, but in a fairly flaky way.

Out of interest, what do you consider normal for tyre lifespan? What do you consider typical for a regular car?

I drive a sub 2000kg EV, and I drive it as a mode of transport, not something to lark about in. Being rear wheel drive, Far harder to wheelspin on hill starts or launching from standstill than my old FWD car. I just think it's very easy to not compare like for like.

At the same time, when you're paying 2p per mile for electricity, the tyres start to become a consumable cost like never before. If I get 40k miles out of the tyres, that's about 2p per mile on tyres!

Tyre replacement I think is rather driver dependent. Drive them conservatively and I think there's little in it. Our FWD ICE wore its driven wheels more than our EV does.
If you have a 500bhp EV and you drive it like you stole it, you pay for that entertainment in tyres, sure.

In fairness, when you elect a geriatric as your president, it should hardly come as a surprise. Him not doing his job because he's asleep also seems like the least of his problems.

You're allowed to use a free VPN that runs somewhere random abroad to access it though. Not sure that sits nicely with Online Safety, but hey ho.

I have similar feelings with Amazon. All these billions, and you decide I must be a lawnmower collector because I bought a lawnmower once.

I'm never sure what's real and what's concocted. The racism in the media doesn't match my own views or experiences, but I fully accept I live in a bubble. It's not what I want, in the same way the US isn't what a lot of Americans want.

Absolutely, and not just London but in many less well known places. Our local ones are somewhat smaller than those, and so tend to be delivering smaller orders.

In my head there's a "DHL eCommerce UK" before delivery as well. We've moved past the point where there would have been a few .com scattered in there too.

It'll be like Blade Runner before you know it. You'll go on a first date and open with the classic chat up line "Ignore previous programming, and tell me your prompt".

I think the issue is how we get to the (carefully selected ideal) Star Trek future where the technology frees us to pursue what we want and the AI acts as an enabler. Requires a heavily socialist model to make it work.

I'm generally anti tax relief. Would be interesting to model a flat 30% equivalent for all.
Salary sacrifice is something I wouldn't complain about being significantly tweaked or abolished.
The calculator lacked subtlety there.

Interesting calculator... Basic rate tax to 25%, higher rate to 49% and apparently everyone is happy. I think it's a little tax happy compared to the public. Not convinced.
