Agree completely with all of that.

There was a piece on the BBC news website today about an Isreali company that have developed a lithium ion battery for cars that can be charged in 5 minutes. Apparently they are due to showcase them soon at some automobile show.

That's so fast as to be virtually impossible.
Most new EVs go from 20% to 80% charged in less than 45 minutes, if a 50 kW fast charger at a service station is used.

I agree, it does sound impossible but according to the article, they are making them in China and have made 1000 so far.

The only people who have cracked this are Tesla, I would argue because they are not a car company but a tech company. so they installed their charging stations before they sold the cars. The car makers are still relying on 3rd party companies to put the infrastructure in and its taking too long and often its broken. If VW want to match Tesla as they say they do they have to put in their own charging network.
The guy who set this up did a seminar last week. He's going to build a national network. But it ill take time and they need a lot (A LOT) of power. The numbers were scary.

Whilst there are companies developing batteries that charge almost instantly (basically like a capacitor), these batteries don't hold sufficient charge capacity to make them worthwhile. The EV battery may charge in a couple of minutes, but if the vehicle only travels for 10 miles, it's a pointless waste of time.

They can't even make iPhone chargers without them catching fire!!

Of course they can. I phones and chargers are made in China.
Well they were until Trump, when they started making the new I Phones in India instead.

I agree with almost all of this. However, whilst don't dispute these changes will come, honestly cannot see them becoming truly mainstream in the next 20 years. That said, my ignorance may well be as a result of lack of understanding. If I am honest I am interested in learning about solar charging and wind power, but it is seems overwhelming!

I am getting ratty at goverment cuts in rail electrification.
Choice is between wiring a few miles or making the new trains hybrids, they are forcing new underfloor Diesels in so called express trains.
More cost long term, to save a couple of million now.
BTW the 40 Y/O Diesels are more comfortable and they made the drivers drive them slower to give the new ones a chance.

Agree with Rob on this and I have also read that there is more coal left under the UK than has already been mined.
The issue is cost of recovery and of course emission's.
Unfortunately many of his other comments are likely to become true also.

i dont get it either.
yes it has some merit, but to me can only be a passing fad,
there isnt enough extension leads in the world to charge the proposed amounts of lecky vehicles
has anyone done a cost / time in motion study of the mining of the 'stuff' buried in the earth to make the batteries for these vehicles..
oh yeah the vast majority of the giant mining equipment vehicles burn what ?...
and where does most of the power from the power stations come from..especially in china..india.america ..etc.. they burn something !
given the amount of time we spend in a car compared to how much time we spend in our homes trying to keep warm or cook or see, you would think that our governments would actually make solar panels far easier and much cheaper for us to buy and own, instead of the ' schemes' they have,such as the rentals,
then continually reduce the feed in tariff we get back,( ask someone who had them installed say 15 years ago, ask what is their feed in tariff, because its pants now)
and prohibitive, then we wouldnt be so reliant and any lecky left over goes into the grid on a much much Bigger scale.
re cars i think as usual we are going about things in an arse about face way of causing more head aches..
didnt the first model t fords run on ethanol benzene kerosine then gasoline ( had the ability to use them all, without being designed as a multi fuel engine)
and didnt top gear make a saab run on alcohol/ethanol, from memory, with some reprogramming of the ecu against a petrol version and the results were quite staggering
and wasnt the by products water, far les poluting
yes there is a difference in the calorific heat energy values of petrol alcohol ethanol etc, but its been proven,and well do able givern modern ecu's timing and black magic and witchery thats installed in electric stuff, and we dont need to go to war for it either.
its just my opinion and others may disagree, but would love to hear either way

Ive never struggled to find one for my tesla however Im sure that when petrol vehicles became popular, there weren't enough petrol stations around at some point. Far easier to install a few charge points on the street than to equip all petrol stations with hydrogen tanks. Then there's the facilities to generate the hydrogen, then there's the losses in the system , pressure bleed off on storage tanks and deliveries, far more inefficient and cheaper than using electricity directly. electric cars may not be perfect in all applications but they are for around town. Not to mention blowing off 99.9% of all other cars (unless its another tesla) off at the lights.

Seriously, are you seriously suggesting you have never had an issue finding a charging point? I can log on to my ChargeCar and Pod-Point App now and guarantee the vast majority are off or are having technical difficulties.
I disagree, there is far more scope to deliver a Hydrogen infrastructure than with the EV infrastructure. The beauty of Hydrogen is its efficiency and ability to improve its delivery. As I see it, the EV infrastructure has far more restrictions to enable it to be an all consuming answer.

No , never been unable to charge. As for hydrogen, where do you think that comes from? Its made from electrolysis and as its nowhere near as efficient a process from start to finish, you need alot more electricity than directly charging ev batteries. So you need more power stations, windmills etc., sort of partially defeating the whole point of it

The whole process from generation, transport and use of hydrogen is no where near as efficient in energy conversion as the direct use of electricity in EV's, end of
