It’s very simple. You don’t change your engine or ECU (car computer). A quart-size (95o cc) container, usually made of glass but can also be plastic or metal, is placed somewhere under the hood. You fill it with distilled water and cheap household electrolyte (causes electrical current). The device gets vacuum and 12 volts from the engine, and produces water gas as shown in the video inside.
The electrical connection is very basic - we have eliminated the need to use relays or any other complications. The device connects to the 12 volts of your battery via the ignition switch, to prevent hydrogen production when the engine is off. The device is fuse protected and draws very little current, only 1-3 amps! This could take 10 minutes or less to connect.
Did you know that a modern gasoline engines has an average efficiency of about 25 to 30%. In other words, 70 to 75% of the energy stored in that expensive fuel wastes as heat, pollution (unburned fuel!) and vibration, and only about 25% of energy moves the vehicle. 
Our simple water gas conversion guide will show you how to use electricity from your car’s battery to separate water into a gas. Also called brown’s gas or Hydroxy, burns smoothly and provides significant energy - while the end product is just water! It provides the atomic power of hydrogen, while maintaining the stability.
Massively cut back on gas costs, Dramatically reduce your greenhouse emissions and receive irs refunds. Because water gas is already in gas and diesel, it is very easy to extract tons of fuel from it.
