No, hadn't heard, I'll have to go look it up.

A year or so ago I heard a news interview about an aluminum/oxide fuel cell,
that is, the fuel is aluminum, handled in such a way that electrical
energy is released as it undergoes controlled oxidation. Haven't heard anything
since; struck me as sounds good in theory, not so much in practice and economics.
