Gas leaks are usually innoccuous until it's too late, H/air ratios for ignition are quite wide, and the ignition is EXPLOSIVE. LPG/LNG: I'm told a gas cigarette lighter is about equal to one stick of gelignite in energy [perhaps under ideal conditions?]. In event of collision, compressed gases leak rather easily, and present a real risk to the remaining occupants and any rescuers. Why do you think gas powered vehicles have that red tag on their numberplates? It's a warning label!!!! Petrol is risky too, I'll admit, but petrol leaks are a little easier to prevent, and diesel is safer still, being more difficult to ignite. I am amazed at the level of gullibility in the Oz military which allowed them to be associated with Firepower-an obvious fraud to any decently educated mechanically minded person. >100yrs of motorcycle engine/fuel development has pretty well covered the field without such radical success==be very suspicious, indeed, assume fraud from the beginning. Bit like that other innane idea, putting a turbulator into an inlet manifold-can only work on the very poorest quality induction systems, and then only marginally. Ever seen any on a racing engine??? Why not??
