yep, and the technology makes more sense now. A lot of the extra energy isn't coming from thin air. The energy that is produced during normal combustion causes waste of energy in terms of heat. But I guess this doesn't produce as much heat, meaning that the energy must be staying somewhere else (not saying it is converted to something else useful - it also could be that it is converted into another wasteful byproduct. But hey, at least that is one more notch in why it could possibly be true).
