They could run on diesel powered generators. No petrol station manger would be caught without one.One of these days, you might even manage to work out what petrol and diesel pumps run on...
and give Big Oil another £100. I do miss that...
You gave the money to "big car manufacturer" instead, to cover the ludicrous list prices of EVs and the steep depreciation. Some of the materials for those extortionate, non-replaceable batteries come from questionable sources too.

Still being in regular use means both cars have long since repaid (if that's the right expression) the energy & emissions produced in their manufacture.

Ah yes... I see that a lot...
But of course, you wouldn't be able to use those same diesel generators to charge EVs would you...?Well... I didn't. Remember, it's a company car. So my employer did. But even if it had been my own, I think I might still end up not really losing out. Saving £200 every month on fuel, covers a fair bit of depreciation!
I guess you're referring to artisanaly-mined cobalt? There's quite a lot of BS doing the rounds there. People talk about "slave labour" and "child labour". Most Cobalt comes from the Democratic Republic of Congo, and is actually industrially mined using paid adults and heavy equipment. However, in areas where the mineral seams run close to the surface, you get families and villagers mining their own. (Hence the terms "artisans" and artisanaly-mined). Now, don't get me wrong, the conditions are appalling to a Westener, and they DO certainly use children. Although, it's not a "slavery" thing, these are usually families where the whole family, including the kids, work at it.
However, there are a few other things worth knowing about cobalt:
1. Not all EVs use it. Some use different battery chemistries that don't need it at all (lithium iron phosphate).
2. Pretty much all the others are reducing cobalt content in their batteries anyway. (Only about 10% in mine).
3. It is possible to buy certified cobalt, with traceability so that you can see where it has come from - indeed, the manufacturer of my car, makes a big thing about this.
4. one of the biggest users of cobalt is the petrochemical industry. (They use it in catalysts as part of the refining process for petrol and diesel - and have done for years, but strangely, the anti-EV brigade's consciences don't seem to be quite quite so troubled about that, for some reason...
If it wasn't the cobalt you were thinking of, post back with whatever it was, and I'll try and answer that query, but it's usually cobalt that gets mentioned.
You would not and that would be stupid. Half of the diesel would be lost to waste. Charge points would not be allowed to carry diesel/petrol in any case. I am shocked someone like you in the trade doesn't know this.you wouldn't be able to use those same diesel generators to charge EVs would you...?
A single diesel generator would power the entire petrol station, and it has unlimited diesel charge because it is a petrol station ! A single generator will recharge unlimited number of ICE cars. Using the same generator, you could probably charge one and half EVs.

Why? Do EVs need a different sort of electricity to petrol pumps? One of the most frequent anti-EV arguments (which also has very little truth in it) is about EV chargers powered by diesel generators. Are you agreeing that doesn't happen?
Couple of things there:
1. Can you remember the last time there was a big enough power cut to take out all the EV chargers within a (say) 20 mile radius? No. Neither can I. So this would be an extremely rare event. The most likely thing that would happen, is that my car would just sit on the drive with however much electricity was in the battery, until power was restored. In the extremely unlikely event that I needed to charge during the power cut, I'd just drive somewhere outside the area affected and plug in there. It usually has at least 150 miles worth in the battery.
2. No, the diesel wouldn't actually be wasted. Ironically, you're not far wrong, with you estimate of "half", but actually, about 2/3 of it would be wasted - same as if you were burning it in your car engine...
So basically, I'd be "almost" as ineficient as you, every time I charged from a diesel generator during a power cut.......which would be about as often as I drove from Land's End to John O'Groats...
That's good to know. I'll remember that, next time you share some anti-EV meme showing a charging point powered by a diesel generator...
Depends how big the generator is, doesn't it?

So you own nothing with a lithium based battery? Perhaps your mobile phone is powered by a tiny petrol engine

Just out of curiosity, how does a car (ICE or EV) "repay" its manufacturing CO2 emissions? Do they go through a phase where they suck it out of the atmosphere or something? If so, what do they do with it once they've done that?

Fallacious argument. A diesel generator does not generate diesel, it generates electricity. It does highlight the myopia of your perspective though; powering the pumps of a petrol station will not refuel an unlimited number of cars - it will refuel as many cars as the petrol station tanks have fuel available for. It's kinda like a micro version of planet earth, where there is a finite resource burnt through at a rate millions of times faster than it generates.
Now, it turns out that the ability to use the sun to generate the fuel for an EV is orders of magnitude faster than using the sun to generate vegetation that you leave to rot for millions of years to turn into diesel. Even growing rapeseed for biodiesel isn't anywhere near as fast at recharging your diesel car as a solar panel is at charging an EV
About 115 gallons of biodiesel per acre on rapeseed oil, in good conditions. We simply don't have enough acres of arable land in the UK to meet our diesel needs.
It's the opposite really. ICEs have a low up front cost and generate far more from fuel costs. Keeping them for ages just means you've generated loads of emissions.Good for him, shake his hand for me .. mine's a '98 523i SE auto

EVs 'repay' their higher build emissions because their per mile emissions are far lower.
Yet, you believe you have unlimited land to park EVs up for charging. Reality is that there is no land at all if you need to go anywhere.
