Um.  I don't think that making Aluminum Oxide out of Aluminum
is any less "destroying" the Aluminum than making CO2 and H2O
out of a hydrocarbon is "destroying" the hydrocarbon.  Of course,
the CO2 tends to be allowed to drift away, while the Al2O3 is
a nice solid.

I wonder if the Al-->Hydrogen process discussed here would be
applicable to Aluminum based batteries as well?
