What Albo and Bowen don't understand is that if power is lost for more than a few hours the molten aluminium in the Potlines solidifies and has to be dug out manually This science site explains it:
"The smelting process requires large amounts of electricity. A reliable and uninterrupted electrical power supply is a critical issue for aluminum smelters. Alternating or AC current supplied from the grid must be transformed into direct or DC current, which requires the use of large rectifiers, transformers, and sophisticated monitoring systems located adjacent to the potline building. The most inherent risk in aluminum production is a loss of electrical power. A failure of electricity supply lasting more than 2–3 h can cause the electrolyte in the cells to cool to the point where its electrical resistance is too great when power is restored resulting in shutdown of all cells. It is expensive and time consuming; usually it will take several months, to restart a frozen potline because the solidified aluminum and electrolyte must be physically broken out of the cells. Thus, significant business losses will be incurred due to the interruption in the event of a potline freezing. The remaining lifetime of the cathodes will be shortened due to the extra thermal stresses inevitable with shutdown and restart of cells...." https://www.sciencedirect.com/topics/engineering/aluminum-smelter

Albanese is typical of a Uni indoctrinated idealist who is convinced that running a Nation is no different to writing a thesis on the sex life of teenage dung beetles !

Albanese should be put on trial for mass immigration.
Dutton is not fit to serve at all.

Meanwhile a Brisbane company is developing a commercial aircraft powered by green hydrogen - book your tickets now, what could possibly go wrong?

A- I agree.

How much longer before those idealist idiots wake up from being Woke ? There is no such thing as Green renewable energy !! Literally 99% of products either contain oil or require oil to produce. Just look at wind arms & Solar panels & then there are the batteries !
Are educated people really so stupid not to see that ? I speak with many everyday people & literally every single one understands that. It's like one can only be stupid when educated !
