I have range and recharge anxiety, but I'm also aware that those problems wont be solved if we use them as excuses never to develop or buy electric cars.
You misunderstand me. I have no ideological problems with EVs. My problems are very much pragmatic ones. Why would I - or anyone else for that matter - buy a car that costs twice as much as a regular car and yet cannot go as far or be as convenient? I wouldn't... and no one else does either - hence the 0.5% sales so far.
Why on earth should I consider a car which has such significant limitations? And I am seriously doubting how recharge time issues will ever be fixed and certainly not in a way that will ever compare to the convenience of petrol. The entire reasons we have petrol cars int he first place is that it is the world's densest energy source that is plentiful and easily transported. Simply, it works and works well.
If we had any brains we would be using hydrogen as a fuel such as the BMW trial. it is emissions free and is effectively an electrical storage device that is actually refillable quickly and relatively easily. And the entire range of existing cars can use it with minimal change to engines.
your right, if we could get a electric car in Australia its more expensive and probable will be for a few more years.
Charging wont be a issue,
a very small part of the population do big km's in Australia , 40kms average a day and those that do own a ev love that they never need to goto a gas station as they charge the car when they sleep.
The charging times and size of batteries r getting better and better and now they r trailing wireless charging, basically charge your vehicles as it goes along the highway.
Hydrogen might be good one day but its still has a lot of engineering to get good now. that could be a whole other subject.
I think your mistaking hydrogen gas added to normal fuel Like HITek in California r doing where they get 30% fuel decrease injecting hydrogen into a existing motor
I hydrogen fuel cell car is a whole other beast and no existing motors can use that technology they run on the fuel cells.
So far the only efficient way of getting hydrogen is using LPG so it kind of dumb and u need I think the gas pressurized to 6000 pounds and its a corrosive gas as well.
All I think fixable with engineering ,but will take years.
RE Hydrogen... Check out the BMW hydrogen project. They have quite successfully been able to reun existing cars on hydrogen compressed into super-safe cylinders.
Your claim about "a very small part of the population do big km's in Australia" is ludicrous. EVERYONE in rural australia does big kms. And most people in cities also like to go on holidays where they tend to.... DRIVE LONG DISTANCES.
Averages are pointless in this discussion because that's where EVs fail and fail badly. Most distances travelled are relatively short but when I want to do long distances, I can. Easily. EVs require careful planning at best or more likely, cant be done at all.
Wireless charging on highways is perhaps the biggest fantasy you have raised yet. The infrastructure cost would be beyond massive and absolutely impractical bordering on the impossible. And wireless charging is pretty easy for a phone, but an entirely different matter for thousand times the charge rate.
