This is a link to a news story about a new EV charging service area. This is what is needed and lots of them!

EV battery need a major technical advancement, we need breakthrough in battery chemistry using other battery materials, like Lithium Sulphide, Sodium Sulphide, Sodium Air or other kinds that probably incorporate also graphene technology
It is true that the current NCM lithium battery has much less energy density when compared to fossil fuel (much more mass in order to release the same amount of energy)
New battery material has much higher energy density and is greener to manufacture and raw materials are more abundantly found on Earth

The best EV battery makers are those from Korea and Japan,
but chinese companies get subsidy from their government as well as steal IP and use forced knowledge transfer to obtain technology to make slightly inferior but still competitive battery

actually, Tesla is among the cheapest and most cost efficient EV in the world right now. Many chinese EV makers when without government subsidy sell EV at much higher price than Tesla and are far more inferior, more energy inefficient. Despite the fact that nearly every of them involves stealing IP from western rivals or forced knowledge transfer.

The scientist are making progress in 4th gen reactor that can burn those radioactive waste that have extremely long half life and make available nuclear fuel last longer. The technology behind is neutron activation.

The problems for EV is that the motor requires strong permanent magnet for the best efficiency, these magnet need rare earth elements that currently primarily come from china.
But I heard that Japanese are making progress in making permanent magnet that do not need rare earth elements from china


solar cells are currently highly inefficient, cost many energy to manufacture and has low efficiency in generating electricity. but the future material Perovskite solar cell has much higher conversion efficiency and cost much less energy to manufacture and use abundant elements. Solar energy will be much greener in the future

Just read another article on electric cars:

https://www.tomsguide.com/news/i-used-an-electric-car-to-drive-to-my-brothers-wedding-and-barely-made-it

This is just not fun, I just couldn't imagine doing what that guy did on my own let alone with children.

If I brought a car today, it would be petrol all the way.
If fat means flavour then I'm ******* delicious!

EV Infrastructure in the UK still seems to need a lot of expansion! Thankfully it is getting better.

Range anxiety is a very real thing depending on what EV you have, where you live and your driving habits. Lowest I've gone is around 1%/2% battery on my way to a charger :P

Can't say I've personally had any bad experiences (yet) though and even plan to hopefully drive across Canada this summer on a 8,000km round trip journey and not concerned in the slightest :D

At designated fast charging stations it shouldn't be anymore than 30/40mins to get a decent charge (if not less), bearing in mind you don't typically charge from 0% to 100%. :)

But yeah, depending on where you live, where you travel a lot etc will depend if an EV is suitable presently. But an EV can a lot more convenient in some cases too.

I went to a cottage for a few nights at Easter which was a few hours away from Toronto, up in the lake region where there's not much around. I found out a few days before we went that the cottage owners had a ChargePoint charger in their garage. Was so convenient!

Left home on 90%, arrived with 25% remaining and kept the car plugged in all weekend and waking up each morning to go on hikes with a full charge was amazing. :)

Unless the charging infrastructure in the UK improves enormously I will buy a new petrol car just before they stop being sold. I'm almost a pensioner ( I'd have been one already except the gov't keep increasing the qualifying age ) and there is no way I want to travel anywhere worrying about being able to charge my car. Its bad for my blood pressure!

Even, 20 - 40 minutes, it would drive me batty. My thoughts may be different if I could charge at home not needing to travel somewhere specifically to charge the car. It's just doesn't sound convenient.

Since I don't travel far this type of vehicle may suit me, in saying this if I had a car I would travel if I could afford the petrol up north to friends houses that are between 1 and 3 hours away regularly so I'd most probably still go for petrol over electric even if I could charge at home.

Yeah from what I gather it is getting better but a lot still needs to be done. :)

It's not as inconvenient as you may think. If you can charge at home, even better. For daily driving it would actually be better since you're living on a full charge each morning for work (so removing the need to visit a gas station).

And on longer road trips, yes you will need to stop and charge every few hours but it would probably coincide with a washroom break / stop to grab a drink or something anyway, and in many cases, by the time you've done your business, grabbed a drink or a bite to eat to go, the charge is done. :)

And often times (based on what I read from other people's road tripping experience across the states) the car is usually ready to go before they are on charge stops :)

Resurrecting this as an alternative has been in the news this week, Hydrogen powered vehicles:

https://www.bbc.co.uk/news/science-environment-58238367

Hydrogen is an interesting alternative if they can get around some issues (high production costs at the moment, not completely carbon free emissions).

They tested a Hydrogen car on 5th Gear recently and one of the huge upsides is that once the infrastructure is in place, it takes 5 minutes to refuel your car - and it can be done at normal garages/fuel stations.... which also keep the fuel stations in business.

I'm sure there are pros and cons on both sides but it's good to see alternatives being explored.
Who's the cat that won't cop out when there's danger all about?
