The ANU has already done them, google it (I supplied the link re global capacity to store renewables via pumped hydro... ages ago)
Ah yes. The one where the top dam when emptied will over flow the bottom dam. And they are supposed to be engineers?

ANU engineers actually, who accept the science driving the COP meetings.
All of them or merely some of them?

Not at the moment, but when the fate of the planet comes into view, they will suddenly discover they can create free money...
But its already supposed to be Thermageddon. How much more time?

Ah only with exhausted fossil fuels. So never.-

Er.. by using existing fossil energy, and progressively phasing fossils out as the newly built renewables replace fossils.
Poor petal. Can't even point to a timeline. Sometime.

Addressed and refuted above.
You haven't refuted anything. Renewables can't make more renewables. Otherwise countries would already be doing it.

I mean they are so cheap aren't they?

It's simple engineering...
And since you don't do science you wouldn't know anything about engineering.
