What does 1 kilo of Aluminium cost?

Modification of the calculation:

1 kilo of alu cost,s around 1,70 euro
Proven is that you can run a car for like 500 till 600 km on 1 kilo alu with NAOH hydrogen, which is H2
Assume that your car is delivering 50kw during that trip, we also assume that the trip took 5 or 6 hours.
Thats 50kwh x 5 = 250kwh of energy coming out that 1 kilo of alu
If you want to know how much alu you need for 24 hours of production, then multiply by 4.8
So, 4.8 kilo per day for 1200kwh
1 kwh is sold for 0.07 euro cent. 1200 x 0.07 = 84 euro's per day
365 days x 84 euros = 30000 euros per year !!!
4.8kg x 365 = 1752 kilo's of alu is used in 1 year
1752 x 1,70 euro = 3000 euro costs....

In theory you can make a wopping 29,700,-- euro's per years if you run a generator of 50kwh on alu and NAOH

Sounds like a pretty good opportunity.  Keep in mind that the metal/air battery (with electrolyte) also puts out H2 during its operation.  The tricky part is preventing the oxide layer buildup which prevents further reaction.  Currently, researchers are mixing in Gallium, which is pretty expensive to reclaim.  Years ago, some guy ran his car with hydrogen by scraping a fuel wire across a rod, under water.  Friction either prevented the oxide or caused it to fall off, so the wire could be reversed and reused a number of times.  I don't know if a graphene layer would block the corrosion, but that does work in car batteries.  Maybe we can reverse pulse the cell periodically, to blast the alumina from the surface?

There could be a lot of money in this, as long as you can set up the debt account to get it started.

Yes, the opportunity might be real.
So, what i did today, is that i took a testprobe of alu and submerged it into water (reversed osmose) with some KOH.

Here are some short video's i took. Maybe you can follow my thinking here.
The first video is of course the start. After 1 minute, hydrogen starts to occure.
The two other videos are taken 5 minutes after eachother and after the start video.
It looks like to me that the proces is pretty stable, depending on pH levels, and water temperature.

Sofar, no oxydation.......

It looks like that the aluminium testprobe is loosing mass.
That part i understand.
The thing is that the water is getting dark and i also see that the reaction is getting less after some hours.
So, i think that the KOH in the water is getting oxydised or consumed.....

Any comments on that?
