Re: Crazy gas saving scheme, will it work?
To address the alternator quandary, you stated:
"I'm thinking about it like this... imagine that the alternator was disconnected from the electrical system for a moment here... the engine and electrical system are running off the battery alone in this hypothetic situation, but the alternator is still physically installed. Even though there is nothing drawing current from the alternator it still spins because it's physically connected by a belt, which costs engine hp for it to be connected, right? And even though there's nothing using the current, the alternator is still generating electric power, but that power is completely wasted because there is nothing using it right? So if you then use that electricity to power an electric motor that somehow aided in propelling the vehicle forward, any hp that the electric motor added, would be an increase in efficiency, right? Ok, so that's basically what I'm thinking will go on here, except instead of an electric motor, I'm going to be using a chemical reaction to create some minute extra bit of hp."
Now, using that logic, I see what you are saying. What you are not understanding is that the larger the load on your alternator, the more energy required to spin it. An alternator is an AC (alternating current) generator. The alternator's regulator / rectifier changes the AC to DC to feed the car's 12v system. WHEN A LOAD of current demand is increased, the alternator DEMANDS an increase in power to turn it. You know how when you jump start another vehicle with your car running? You hear the "draw down" on the engine when you finish connecting the cables? That's the power demand on the engine to produce the amperage to charge / start the other car. You rev the engine a bit to get higher revolutions to produce more power.
YOU WILL BE DRAWING ADDITIONAL CURRENT TO CREATE THE GAS in your extractor. It will require more power. It will load the alternator a bit. That's why everyone's saying you don't net an energy increase. The alternator is loaded more because of the power requirement. Yes, you're argument is correct IF there was "no load". The alternator always produces a bit of power needed or not. The factor is how much power is needed to run the gas extractor vs the power created from running it.
Clear as mud?
