I didn't spot the chargers as they were at the opposite corner of the car park.

it could have been "cos i parked the car next to it and got out my side"

in popular car parks is good
at or near home, and at a green home cost per kw for all, seems to still need some strong nudges on infrastructure development capable of the load and accessible to those who do not have at home parking

as mentioned planned range was no issue

A bit of news is Lithium Sulfur batteries being sampled to car companies.
Hard to find the energy density they are being sampled at, but I'd speculate a minimum of 350wh/kg.
That's double the density of current LFP batteries and again without Cobalt or anything else challenging.
Also apparently cheap to make.
Lithium Sulfur has previously had life cycle issues which presumably have been overcome, but it invites the question if this sort of battery needs a refresh after 100,000 miles need that cost much? the materials are still all there?
At any rate it would take todays 200 mile cars and make them 300 miles cars with smaller lighter batteries.

the oil industry has massive amounts of sulphur they can not sell, mountains of it in some places
there are other "from waste" sources and it is quite common

li is not uncommon and often available in economic concentrations

neither would be a pinch point for making every battery in the world

as you say, when it is tired recycle it as a very rich ore

that seems sustainable

A pisstake from an EV forum:

I am thinking of swapping my ev for an ICE car ….

1. I have heard that petrol cars cannot refuel at home while you sleep? How often do you have to refill elsewhere? Will there be a solution for refuelling at home?

2. Which parts will I need to service and how often? The car salesman mentioned oil in the engine and timing belts that need replacing and a box with gears in it. What is this? How much will this service oil change cost and how often – and what happens to the old oil. Also, apparently these petrol type cars generally stop on the brakes alone – so the brakes wear out much faster – how long will they last compared to my current car which lasts over 100k miles?

3. Do I get fuel back when I slow down or drive downhill?

4. The car I test drove seemed to have a delay from the time I pressed the accelerator pedal until it began to accelerate. Is that normal in petrol cars?

5. We currently pay about 1.2p per mile to drive our electric car. I have heard that petrol can cost up to 8 times as much. Is this true?

6. Is it true that petrol is flammable?

7. I understand that the main ingredient in petrol is oil. Is it true that the extraction and refining of oil causes environmental problems as well as conflicts and major wars that over the last 100 years have cost millions of lives? Is there a solution?

8. I have also been told that you have to transport oil all over the world to turn into petrol or diesel, and these ships have in the past damaged the environment by leaking the oil.

9. I have heard that cars with internal combustion engines are being banned to enter more and more cities around the world, as it is claimed that they tend to harm the environment and health of their citizens? Is that true?

10. I have been told that these internal combustion engines make a noise when you start them – so early starts can wake people up, and driving a lot of internal combustion engine cars in towns makes towns noisy.

11. is it true people can steal the fuel from your tank?

12. what is the drop in range in cold weather, I've been told a car that does 45mpg can drop to 37 mpg in winter – just curious on that one.

13. a friend told me that the exhausts wear out – is that true, and people steal them for the rare material used in them.

14. I was also told – that the exhaust gas isn’t good for you – and if you leave the car running in a confined space – like a garage – you will die – surely that isn’t true is it?

15. next door told me – these petrol cars – carry around 40 to 60 litres of highly flammable liquid which is pumped into a steel cylinder, and its then exploded to generate expanding gas to move a piston, and turn linear motion into rotary motion. Why would anyone want thousands of explosions happening within a few feet of where your sitting.

16. a guy at work told me – he has a petrol car, and it leaks oil. When he parks it – surely that’s not right is it – leaving dirty marks on the floor and contaminating the environment so directly. How long before this happens if I change.

17. my dad told me – if you buy a diesel car – the hand pump smells very bad, and you have to wear special gloves to stop your hand smelling, and if you spill it on your clothes it terrible.

18. is it true – the petrol and diesel is so dangerous, that you can only buy the fuel at a special filling station, and not anywhere (hotels/Car parks/Home/Work)?

19. while technology is advancing, will I ever be able to refuel my internal combustion car for free using only the sun?

20. would I be better off going straight to horse and cart, and not buying a horseless carriage – they sound pretty awful, burning dinosaur juice and polluting the environment whist funding conflict and war and consuming raw material at an unbelievably high rate.

Also in winter you can't remotely start the car so that it heats and clears the windows!

is it true that my new ice vehicle requires lots of heavy and expensive engineering to connect the torque curve of the engine to the speed, traction and torque required at the wheels?

is it true that when i fill my ice car with fuel every liter of fuel i put in displaces the same volume of hydrocarbon fumes, are they harmful?

The problem I have with our hybrid is that I react faster than the electronics so I have to wait for it. Is it just ours or are they all like that? Generally I find that is the case with computers and other electronics.

That joke is quite good, but perhaps people also ought to think about the nasty smellies they use in their car to clean it, make it or themselves smell nice. If they knew what went into them they would think petrol and diesel were quite harmless.

the piss take post is amusing but does show naivety in places

like number 7 - until we are 100% renewable, then that smugness is misplaced.

number 8 - we currently use diesel to transport timber from other countries to burn to make renewable energy.

references to thefts - they will come - there is just more to be made from ICE vehicles atm, but when EV is mainstream, then there will be some way theft from EV will be a problem

number 1. privilege. most car owners do not have their own parking space, charging at home is only available for the minority.

19. the use of the word 'free'. it's not free. it might be a really good idea, but it isn't free if you have to pay a lump sum in the beginning.

20 yes actually. Better still, just drive less. much better for the environment than buying an EV and continuing to drive many miles.

I know, I know.. it's a joke, and very good points made by reversing the situation, it does open the eyes to things we are just used to. I do believe that EVs are the way forward, but every time people make statements that are misleading, like 'free', it is unhelpful to the cause, imo. I intend to go the EV way eventually myself, but I do like to be realistic about the pros and cons.

it's a bit like when I went to a thing when people explained their experience with solar panels. Several times it came up that the return was 'better than keeping your money in savings' and it probably is. but the thing about savings is you can get the money back, whereas if it is spent on solar panels, then it is spent. it isn't a realistic comparison. You might have needs for that capital in the future and it does not, apparently, increase the value of the house by the amount you spent in solar (plus of course... privilege - owning own house, being able to afford panels)

Re 7 according to Gridwatch right now we are generating 40% of our demand by solar and wind. This number would be bigger if every wind asset was already connected to the grid.

Even if we accept the ridiculous use of ethanol in petrol or palm oil in diesel, 90% of the fuel used is fossil fuel.

I haven’t been checking regularly but there have been many times this year when renewables have made up 90% of demand. National Grid expect to have periods of 100% renewables by next year

Once storage is built at scale then this will be exponentially increased

the great british (non fossil) power company, competing in the energy supply market with both political will and access to significant funding might swing the balance quite quickly.

sustainable is cheaper to make so pricing fossil into history is plausible

fossil will kick and wriggle, smother it

I realize that they're probably not common in the UK, but remote start is very common for ICE cars in the colder states

And even if your electric is half coal powered, the efficiency of EVs relative to ICE is so much greater (yes with transmission and storage losses) that you're still using fewer fossil fuels..... ICE vehicles don't recoup any of their spent energy on downhills as well.... There's a good reason that it typically costs less to move an EV the same number of miles as an ICE car
