Edit - latest article I can find from a month ago says it’s still not known if it will be available here, but other articles say definitely not, but with a fully refundable deposit there’s not much to lose putting your hand up I suppose if you’re into that kind of thing.

Yes, with the deposit being just A$150 and refundable it's not a huge ask. Interesting point is that my mate, who is a certified petrol head, is expecting his next vehicle to be electric.

If you have money and want to go fast just for ****s and giggles, an EV fits the bill perfectly.

Home charging with battery and solar is great but when you're out and about is a different story.

Its been shown that it takes about the same amount of electricity to produce a gallon of fuel , as that electricity could drive an equivalent sized EV the same distance. So no net increase in electricity is needed to convert the fleet to EV.

Not so good in Australia though as we import 95% of our fuel. Clearly we will need to go nuclear. At least we wont be dependent on Alah for our fuel. As it stands anyone wants to take over out country just hast to cut off our fuel supply and wait 21 days, then we will capitulate.

A litre of fuel produces 8.9KWh of power but only takes 0.756KWh to produce that same litre of fuel. I’ve seen the articles that claim it’s one to one but it’s not even close. Add to that you have massive power infrastructure to refineries - how do you then take all that power and put it elsewhere? The infrastructure where the power will be needed can’t cope with it plain and simple hence the issue that is becoming a reality. No amount of spin fixes this but happy to look at the links and info you have and their calculations.

Take a average sized shopping centre for example - will have 3 or 4 switchboards around it supplying power to the shops - drawing around 4000 to 5000 amps per phase on a warm day with its switchboards at around 60 to 70% load (I’ve measured all of this at many shopping centres, I’m just using this as an average and example). That leaves a couple thousand amps before the systems maxed out. A fast charger will draw let’s say 100 amps - they can be double this - so it’s not hard to work out how many chargers a shopping centre for example could install before their infrastructure is maxed out and upgrading this is a massive and expensive task. That’s why you rarely see more than a few chargers at any one spot and why most places where they’ll be needed won’t have infrastructure that can cope with more that a few here and there. It’s the single biggest issue EV’s face IMO.

If those nuke powered subs go ahead the knowledge and workforce skills we can develop if managed properly can translate to homegrown expertise to develop nuclear power stations in this country in the future. Combined with wind and solar and storage we should have an abundance of energy in our future.

Wind , solar and storage are fine but biomass, biofuels , thermal and nuclear and others should all be on the table, can never have too much variety in energy production.

Now where is that dual electric motor diff for my disco, screw you Rivian, I'm coming for ya!!

I do hope this does open it up to Nuclear power in Australia but it will be decades away if it is. Even then, that doesn’t fix the issue of getting the power to the EV’s

It’ll never happen. Nobody involved in renewables wants reliable base load power. Too much money to be made building short lived infrastructure and devices for wind, solar and batteries.

I do not think that this will be the case. I'll bet that the nuclear reactor system for the subs will arrive in Adelaide(?) as a complete, sealed, fuelled-for-life unit, ready for installation.
