Do you recycle "elemental aluminum" instead of throwing you beer can to the trash?

There's recyclable and 'Recyclable' - the aluminium beer can is still pretty much all elemental metal, so it only has to be melted back down again; a tiny fraction of the energy needed to electrically reduce (aka split-off oxygens) your Al2O3 powder in an arc furnace.

Not 'price' in terms of energy it doesn't. But, that aside, what evidence is there that using aluminium to make [some?] H2 that is to 'assist' a gasoline engine will save you or me any money whatsoever?

Of course, it's interesting to see what's possible and I expect for some very specific areas this way of 'making' hydrogen can find good use, but I wouldn't bother using this (or any other) method to add H2 into a car engine, as the returns will be, at best, unnoticeable.
... As an aside, there are Aluminium-Air (electrical) batteries that hold much promise for the future of BEVs.
