Yeah and a 350 HP ICE isn't always putting out 350 HP. What is your point?
200W = 200W
Hows that for math?
a 15 W draw will require a 15 W draw from the engine.
How's that foir math?
You need to come up with a reason for the HHO working that is better than the reality I have shown you.
So explain this Mr Wizzard. How does a Radar system (Raytheon RL-70) for excample, it's a system I've worked on many times, take a 12vdc 25 amp input and put out 4 kilowatts of RF power out the front end? This little radar can detect and track targets at well over 40 miles if the antenna is high enough to see over the curvature of the earth. As one of the math gurus stated earlier 12 vdc at 15 amps is only 180 watts so at 25amps we're looking at what 250-300 watts of power coming in and 4 kilowatts going out?
Power is power right? 200 watts = 200 watts? Can't get out more than you put in right? RL-70 sure as hell does it. It doesn't need 4 kilowatts of power coming in to send 4 kilowatts of power downrange. It's called step up transformers and power amplifiers and depending on what frequency you send an electrical signal into a transformer and the windings insdie the transformer you get a significant increase out the other side. Same goes for power amplifiers. Guess what's on your alternator? You guessed it, a transformer.
The 3A2 power supply for the AN/SPS-64 radar takes in 110vac and typicaly sits on a 40 amp breaker, yet this thing in standby is generating 465vdc to the mod tube and 600vdc in transmit. The mod tube and high voltage board which also gets it's power from the power supply kicks that up to 20killowatts out the array. Q4 and Q5 power amplifiers on the chassis in a push pull configuration receive a 12 vdc input at the collector of Q4 forward biased at the base by .6 vdc at Q4 and Q5 supplied from the control board circuit and push out 150vdc at the emmitter of Q5. That voltage is combined with a pulsed signal from the pulse modulator circuit to produce a modulated 600volt peak to peak modulted wave at Q6, which is a P2240 power amp about the diameter of a quarter and maybe 1 cm tall, that is supplied to the mod tube to transmit a 20 kilowatt pulsed rf signal at 120 milliseconds in long range (that's x band transmission). All that from 110vac at less than 40 amps or else the breaker would trip.
I know the power this thing puts out and how it works because I spent 4 years trouble shooting and rebuilding the damn things. It is very easy to get out more than you put in, you just need the right components in the proper configuration. Don't tell me it's impossible, tell the folks at Raytheon, JRC, Foruno, and all the other companies that build high energy devices that what they are doing is against the law of thermo dynamics and it can't be done. Is there loss? Sure those components get hot as hell and that shows there is loss, but the end result is more power out than was put into the system. The loss is compensated for. Kinda the same thing with the boosters. The loss is compensated for. In your simplistic view of the math involved and your logic an AEGIS cruiser would have to have a nuclear reactor the size of three mile island to generate the 100,000 watts of power the SPY-1 radar is capable of generating, yet that system is operated off of a gas turbine ships generator and takes 110, 220, and 440vac inputs to the various sub systems for the radar, not to mention that same generator is producing power for the rest of the ship.
Your math and logic might actually be accurate for the very simplistic electrical system on say a Model A ford, but todays cars have a very sophisticated electrical power system and my adding a 15-20 amp load to that system will in no way effect the performance of the engine by itself. The reality is that for vitualy 0 net loss in engine power I can generate 1.5 to 2 liters per minute of HHO gas that can be returned to the engine to boost the fuel burn and allow me to tune the fuel intake to lean it out, saving fuel, with no net loss of power.
The idea is so simple that Joe Blow Six Pack can understand it, yet here you are an engineer over thinking the entire thing trying to blast a hole into something that JPL has said actually works and that was in 1975. Those are rocket scientists that agreed that this works in the application we are applying it to. The testing HAS been done if you care to do a little research and find it, and many have posted those links in this thread for your reading pleasure, but you go ahead and keep riding your bicycle and stick to your math and logic. I'm going to apply a proven technology and drive my truck.
