Because that's all we see. He does not open up his machine to let us look inside, does he?
It's as good an explanation as any. I don't know if this thing will consume less net electricity than, say, a plasma-cutter, but as it is used on the market, time will tell.
i'm not sure about the torch, but in the case of the cars being boosted by this it seems somewhat reasonable. no one is saying it is an end-all/cure all. it's being used to assist the engine. to help it burn more effeciently. the setup i've been looking at takes 20 amps. the alternator will not run constantly. the 20 amps will be drawn from the battery, and when the voltage drope below a pre-determined point, the alt turns on, and re-charges it. just as it does normally. i also believe that the alternator takes only 5 horsepower...or less when it's charging. so now, if the hydroxy gas is being added, it's going to obviously add some power simply by the fact that it increases the engines efficiency. as long as it adds at least what it takes out, we're ok.
the hydroxy gas is put in there to help make a better flame front inside the engine. don;t forget that there are not explosions inside the cylinder, but rather flame fronts. so if we put something like this hydroxy gas in the mix, then we can inject less fuel, thus getting better mileage.
at least that's wht makes sense to my tired mind right now
