Only one other person has made a comment on this, but he is dead correct: 30 cubic inches of hydrogen per hour isn't enough to get you to speed. In fact, 30 cubic inches of hydrogen (think about it - a box 3.1" by 3.1" by 3.1") isn't enough to start an engine bigger than 4 cylinders (it might catch, but it'd stall out immediately). We're talking 30 cubic inches of uncompressed hydrogen. Per HOUR. That's 16.6 us ounces, roughly a pint. 0.49 liters. You would need 20 of those devices before you even started to notice an impact on your fuel consumption.
