Hydrogen - H2

Hydrogen gas is explosive. If you plan to experiment, use caution and common sense. Oxygen is created when you make hydrogen and this only aids the explosion. I can and will not be, in any way,  responsible for your actions. If you choose to research Hydrogen, You do it at your OWN RISK.

I use a variable voltage (1 to 30 volt) variable current (0 to 3 amp) power supply for testing.

This is a simple circuit for testing. Baking soda is added to the water. This keeps the water and electrodes (stainless steel) clean.   Notice, the two electrodes going into the water NEVER TOUCH each other.
Harmless small jar with 2 separated coils inside. This mixture is tap water and baking soda. The wires are stainless steel. In some cases I use stainless steel car hose clamps for the electrodes. Copper wire is not a good electrode for this.

 

 
This is the same jar. A circuit is now connected and the water is being used as a resistor. The white on the top of the water is H2 and will clear about one minute after power is  removed. The amount of hydrogen here is not enough to do any real good. 
Not only does this generate hydrogen, you can operate lights and motors while making hydrogen.  This is important. If a device is currently using a large dropping resistor, that converts energy into heat, this circuit can take it's place. The conductivity of the water and the electrode spacing determine the resistor value. Unless you are qualified, please do not experiment with these circuits.  If you do want to test this - Use 12 volts DC or less - Use no more than a 3 amp supply - Do this outside or where there is ample ventilation.  NEVER use house current!  Any testing you do is at your own risk.

I already have a hydro boost on my Van. I do NOT use acid - I use Stainless Steel and baking soda and tap water.  This is basically the same as you see above but larger. The hydrogen is drawn into the carburetor by engine vacuum. Because of what I have tested here, I need not pull additional current from the battery to make hydrogen, I can replace my blower motor resistor with my new water resistor. This will be efficient because it uses no additional current from the battery. I will have a completely variable blower. The once wasted energy consumed by the dropping resistor is now making hydrogen.
