The alternator will then generate power from the "braking action" and not consume fuel.
You cannot step on it while the clutch is pressed.

Sorry to burst your bubble, but I already thought of this.

My version is a little better (i think). What you would do is put a micro switch at the end of the gas pedal travel. Whenever the gas pedal is all the way down, you would be coasting to a stop. With this method you don't have to worry about yet another foot pedal/switch, it just simply is connected to an existing one(gas pedal).

You would also want to set up a disable switch on the dash in case you want to charge all the time, and also have a bypass switch on the dash that would ignore the gas pedal micro switch so you never charge.

I might end up doing this, but for now I don't have any deep cycle batteries.

Oh, and honda's ecu actually already does this. When the tps shows its closed the alternator will charge. I don't know how much drag there is, but it is noticable, as you can coast farther with the alternator off, then when its on(i've tested with my current 1 switch alternator disable, flipping it on and off during a highway coastdown).
