Not so - the emissions and impact caused by the driving a car with an internal combustion engine a given distance is magnitudes of order greater than burning coal to generate the power to drive the same vehicle as an EV over the same distance. Simply, burning coal in a power station is less polluting than driving an internal combustion car.Quote:

Yes but baby steps are needed and it is all progress in the right direction - Rome was not built in a day.
Its not production its been ripped apart to show components, i think it was at Frankfurt like thishttps://uploads.tapatalk-cdn.com/201...bef9411514.jpgQuote:

Yeah .. but, if you want a semblance of equivalency(say to the base model D200 Defer) you'd need something like 200 of them!Quote:

Is it though?! And Rome collapsed very quickly and was very corrupt and immoral.Quote:

Research shows that while EVs are emission-free on the road, they still discharge a lot of the CO2 that ICE cars do. To build each car battery—weighing upwards of 500 kilograms (1,100 pounds) in size for sport-utility vehicles—would emit up to 74% more C02 than producing an efficient ICE car if it's made in a factory powered by fossil fuels in a place like Germany.
For perspective, the average German car owner could drive a gas-guzzling vehicle for three and a half years, or more than 50,000 kilometers, before a Nissan Leaf with a 30 kWh battery would beat it on carbon-dioxide emissions. For larger 80 kWh powered vehicles it’s even longer before they level.
Data provided by Tesla is their power pack loses around 2.5% capacity per year, that Lithium isn’t recycled. A $110k Tesla 3 becomes useless for my needs in under 2 years as the range drops below my needs for a charge.
Whilst not quite as harmful, the next issue the planet will deal with after nuclear waste will be the huge piles of Lithium Battery packs.
Current technology just can’t meet emissions reductions and usability requirements for many. All that is happening is the construction of a lot of throw away vehicles.
Even the renewables to offset emissions aren’t coming in as good as expected:
Recent data on Wind turbines is also suggesting they aren’t balancing the books as planned - maintenance is higher than expected, emissions to maintain are higher, emissions to produce are high, emissions to install are high, damage to area around sites is high. (Have been directly involved in several projects from Wind to Solar to Hydro recently) and seen all the data.
What an EV is good at is Pollution / Carbon shifting, moving the smog and emissions from roads to a larger production facility elsewhere.
For the tinkerers- they’re good for learning and playing.
And cheaper to convert an existing vehicle as a hobbyist than buy a commercial production vehicle.
I find Goingbush’ EV conversion fascinating, and for his niche use it’s perfect. And I’m sure he had a blast building it too. It’s just not a practical vehicle for the wider audience.
The impacts and offsets are not as simple as first appear either... look at the weights of all these “moderately capable” EVs (Tesla 3 can do 600ish km) they weight nearly 2 tonnes. When every vehicle starts to weigh in that heavy that will increase road maintenance requirements, the Emissions increases to repair roads more often then needs to be factored in to emissions models.
Interesting times...
Perhaps a better simile could be found - the start of the collapse of Rome is usuually considered to be the start of the reign of Commodus in 177AD, and its final collapse the fall of Constantinople in 1453AD. Took well over a thousand years. Even if you just consider the "collapse" to be when the centre of government moved from Rome to Constantinople in 330AD, it still took over 150 years.Quote:

I think the point you are missing is that come what may
The emission of carbon dioxide WILL be limited in the near future
Most likely on the back of financial reasons. Insurance companies and finance companies will act faster than governments and the result will be a change in energy development and production.
The fact you are also leaving out is that the creation and transmission of electricity at a centralised location is more efficient on a Carbon Dioxide releasing scale than within a million individual ICE.
The lack of recyclability hardly trumps new technology. Good ole tyres are minimally recycled but there is no shift back to steel rimmed wooden hoops? Geez most Australian recyclable plastics go to landfill now China doesn’t want out junk - packaging hasn’t changed much...
Here’s a Few thoughts on how things might play out.
93% of all business that employ people in Australia have 1-19 employees
Let’s make the maths easy and say 5 dedicated solar fed charge points per business.
That would
a/ not be difficult to achieve space and charge density wise and
b/ be pretty achievable with some simple changes in enticements (thinking FBT exemption on supplying EV power as a Benefit)
c/ selling power back to the grid FIT is not as economically valuable as storing it in a battery.
And well the next thought is even more simple.... “your” kids kids likely won’t drive
There will be exemptions. I can’t exactly call an Uber to our farm gate and honesty don’t think I ever will be able to - but In locations of reasonable pop density you won’t own a Tesla - You will just get driven around in one.
Have another read of your arguments against EV , they sound a lot like “the streets will be filled with horse dung”
The world is changing before your very eyes - maybe not as quickly as some pundits would have it but pretty bloody quick!
