Sure it might be a great fuel but how much energy is required to make the aluminum "feed stock" a few years ago during the ENRON caused power shortage in California, aluminum smelters were shutting down, paying all their employees full wages and selling the electricity that would have been used make their aluminum to California at a greater profit. Unless there is a new way to produce the aluminum and liquid hydrogen for that matter, I don't see how this will save energy.
