Interesting read on electric cars
KeithB:
On EV's a lot of people ask rhetorical questions like:
"How are we going to charge it?"
"How long will I have to queue up to get a charge?"
"How will the grid cope with all of these charging stations?"
"What if I want to travel into regional areas?"
"Where is the energy going to come from to charge all of these EVs?"
"When will EVs be affordable?"
"If nobody is paying petrol tax, how are we going to pay for the roads?"
These questions are raised by the questioner more as an exclamation more than a question. It's as though, because they don't know the answer, there is no answer.
Just look at mobile phones from 20 years ago and compare that to now. Every smart phone is a sophisticated computer. And that happened in less than a dozen or so years.
There is world wide rush by governments and manufacturers to EVs. Scientists everywhere are working on new battery technology. One program at the University of Sydney is aiming at getting batteries down to $100 per KWH within two or three years and is running small scale trials right now
Here's my fearless forecast for 2005 2025 (Typo fixed. Thanks Tryagain.:
EVs will be at least as cheap as petrol cars.
People will still have big diesel 4x4s for recreational and possibly farm use.
Range will be around 600km and they will suit super fast capacitor chargers.
Every service station will have multiple fast charging stations.
Something else will get taxed to make up the lost fuel excise, possibly a lift in the GST.
I'm looking forward to the arrival of EVs and one will probably be our next second car.

Your 2005 forecast was not out by much.
Any change of picking the lotto numbers for me.

I see electric cars as a short term feel good solution to a problem that isn't yet a problem. The problem is the people who think we can dump coal powered stations before we can reliably and CHEAPLY supply that power with something else.
When the world HAS to go away from fossil fueled cars, it may be another fossil fuel....maybe nuclear of some description......and if I had the answer to that, I would be richer than Elon Musk..

They're here now.....rush out now and buy one. They're only approx twice the price of the similar petrol ones !!

I think most people make a much bigger deal out of charging than it really is, with a 500ish km range, you will just charge at home 95% of the time, when you are doing a greater than that trip is when you will use a super charger.
I have seen some videos on YouTube of people trecking across the US in there Tesla, the Car guides them to the Supercharger in the town, they hook it up and tell them how long it will take them to get enough charge to get to the next stop, they go off to get a feed and the Car messages them in half an hr (or less for a part charge) or so to let them know it's good to go.
Sure we don't have the charging infrastructure in place here yet that they do, but Tesla probably already has more chargers than you realise and that number will only grow.
