I heard somewhere what you can make aluminum powder easily by arching two pieces of aluminum under oil (like diesel). Will this work or will it only make aluminum oxide?

you may get Some, but you`ll also have impurities in there too, aluminium carbide for instance.

I just tried this at 12 volts ~60 amps and my clean oil turned black. I will filter it and see if the product is aluminum.

i'm going to go ahead and guess carbon.

just a note, if you do try this use gasoline or something. Plain clean motor oil takes a really long time to filter as I am letting it filter overnight.

Gasoline is a bad idea.

 

Electrical Arching in gasoline is the same thing as lighting a lighter in a propane tank.

 

Motor oil has a substance preventing ignition.

 

Dont do it.

I believe you wouldn't be able to light a lighter in a propane tank since there is no oxygen to allow combustion. Well, there may be a little oxygen, but the concentrations of fuel to oxygen wouldn't allow anything to happen.

the fuel to oxygen ratio is well outside combustion limits it would not ignite.

Almost impossible to filter this oil. Maybe mineral oil or something but not motor oil.
