We will run out of magnets before we run out of lithium.

With a 200+ mile range thats one big city...

This is a game-changer for me. I will very seriously consider buying one of these in a couple of years.

I currently drive just under 32k miles per year and I spend almost £400 per month in fuel. This will save me a fortune and the range is perfect for my commute to work.

Very excited to see more....

That's just as stupid as saying that petrol cars will not catch on due to oil running out.

Surely, as others have said, most people will recharge at home, won't they. How many people regularly do over 200 miles in one go? And for those living in flats on-road or in-carpark charging points will be installed, as they already have been in some places.

Why city dwellers? I don't live or work in a city but I have a 20 mile commute if I go to work, surely that's pretty common?

How many petrol pumps would you typically need if everyone could fill up at home too?

With range, faster fill ups and probably other areas the petrol car still has plenty of life. But I can easily see an average house with 2.4 kids cars having one of each.

While I also am not convinced that electric cars will take over, at least not soon, I'm not sure about this point. It's countered by the fact that everybody already has electricity at home, whereas I don't know anyone who has their own personal petrol pump. Also, installing a charging point has got to be cheaper than building a petrol station. E.g. there's one outside my local library. Took about a day to install.

Lithium is the 25th most common element in the earth's crust. The question isn't whether there's enough, it's how much it costs to extract (both financially and environmentally).
Time to buy shares in Bolivian mining companies?

This is true to a point, but for the really fast chargers, the number that can be installed cheaply at a given location will be limited by electrical substation capacity. Places like motorway service stations will probably need significant infrastructure upgrades to be able to install tens of superchargers.

Currently I think most of it is extracted from underground brine lakes in South America. Perhaps slightly ironically, lithium extraction and refinement is fundamentally pretty similar to petrol extraction and refinement.

charging will mostly be done over night with 'spare' electricity anyhow.

And public charge points will multiply as demand does.

Not at all. You appear to have no understanding of the energy density of petrol or the relatively limited capacity of UK electricity generation/distribution. You'll have a good many years to wait for a full upgrade of that lot!

Exactly! Ozzie's comments are just nonsense.

I commute 60 miles to work, so 120 miles per day. That's well within the range offered and with a super charger installed in my garage it's very practical for me.

Another point to note is that fast charging is really not very good for Lithium cells. Some chemical compositions deal with it much better than others, but all of them lose capacity faster if you charge them very quickly than if you trickle charge them. For that reason, I think we're a long way from them being suitable for people who cover really huge mileages.

We will run out of magnets before we run out of lithium.
Also Lithium doesn't exist as Lithium anywhere because it's far too reactive. It has to be extracted at great cost and at great energy cost too so a lot of CO2 produced just to create one element used in the batteries before you even start thinking of charging them.

Hydrogen gets rid of many of the drawbacks of battery cars - slow refill and limited range. Still not perfect but that's the future.

Over the course of the life-time of a car, the electricity required to split water into hydrogen utterly dwarfs the electricity required to extract Lithium from brine.

Besides, platinum for fuel cells is even harder to find in sufficient quantities than Lithium.

By how much ? Is it very different ?

Hydrogen needs about 3x the electrical energy that an EV would use. Then you have the issue of storing it at 10000 psi. Do you fancy riding around with a 10000 psi tank in your boot?

I'm out.
