The size of nano aluminium particles (approaching 2 microns) is the most critical parameter for generating voluminous gas production. This is because an extremely large surface area is offered which effectively obviates oxidation and provides instant and continuous self-perpetuating gas production without adding an external heat source to the water (after all, a lot of heat is self generated by the reaction). Again, an gallium alloy can also obviate oxidation (the gallium is fully recoverable and recyclable).
