Well, you are convertible AlOx to Al. The current process is AlOx+C+energy ->Al + CO2. This is practical for various reasons. You can directly do AlOx+energy

Well, you are convertible AlOx to Al. The current process is AlOx+C+energy ->Al + CO2. This is practical for various reasons. You can directly do AlOx+energy ->Al+O2. This is the proposal, and it works, somewhat. I am not sure this needed to be in the article, as the balance between 'too basic' and 'sufficient' is tricky.
