It's really a case of Cross That Bridge When You Come To It.

That is what has got us into our present mess.

Hear, hear, Bazz.

Nice to hear there is no affordable, scalable storage solution, here or on the horizon, only blind faith that there will be one.

Further, Aidan opines , "We don't yet know what we'll require, but it's unlikely to be a significant constraint until renewables supply well above 50% of demand."

At 50%, the cost and scale of any current storage technology just for load balancing alone is astonishing, let alone for days or weeks of insufficient wind and sun.

Indeed Luciferase, I read an article where this guy calculated that if
he connected the batteries of all the cars in the world and all the
mobile phone batteries in the world to the world grid it would work for

wait

9 seconds !

Now that may not be correct, but it might be 15 seconds or 3 seconds !
Anyway I think the point is that doing it with batteries is going to
be far too expensive.
As you have seen my question about backup and sunless days seems to be embarrassing.

That's without the cars running? So if it had supply output to meet demand then it would be a winner. Local fracking with minimal damage to rock supplies gas for cars without fuel impurities and super conducting cable is no problem . Mobile batteries as reserves for the odd trip down the road.

Anyone else getting the Tesla Generator add?

I guess that it's a scam.

Yes, I do, but we still have to eat.

The reality is, and it's not likely to change, we have a huge country, with a tiny population, all with huge appetites. Therefore our only answer is exports.

Aidan, I am assuming you're referring to your theory that we have unlimited debt at our bec and call.
