How to Build a Hydrogen Bubbler for a Car
Run your gasoline powered vehicle on clean burning, renewable hydrogen. The core of this intricate fuel conversion system is the hydrogen generator chamber, which separates water into oxygen and usable hydrogen. Build a hydrogen generator housing out of CPVC pipe as part of your hydrogen fuel conversion kit. The remaining parts and systems can be purchased already assembled.

1
Form the main body of the hydrogen generator housing. Cut a CPVC pipe to the correct length for your engine compartment. The generator housing needs to be within 10 to 18 inches in length, any shorter or longer and it will lose efficiency and structural integrity. Use a table or jig saw or a miter box with a hand saw to ensure a straight cut. Cut the generator housing as large as the engine compartment will allow, within the 18 inch limit.

Build two electrode tubes out of steel pipe with wall thickness of .040 inches and .063 inches; T-304 stainless steel is recommended. One tube will be inside the other, larger tube. The gap between the inner and outer electrodes should be 0.3 inches. Cut the electrodes' length 5 inches shorter than the length of the hydrogen generator housing. Drill eight, 1/4 inch holes around the end you select for the base of the outer electrode tube, 3/8 of an inch from the tube edge. Debur the holes after drilling. Repeat the drilling process with the inner electrode tube.

Connect the electrode tubes to the inside of a CPVC end cap using epoxy or sealant. The drilled holes in the base of the electrodes help secure them to the cap by allowing the epoxy to grip the steel tube. Place the outer electrode first. Drill holes in the end cap for the electrode wires. Run wires from the steel electrode tubes through each hole. Solder the wires to the electrode tubes with silver flux solder. After the wires are run through, seal the holes with high quality heat resistant epoxy.

Connect the end cap with the electrodes to the generator housing with JB Weld or similar high grade epoxy. Allow the sealant to dry overnight. Drill a quarter-inch hole an 1/8th of an inch above the end cap's rim and install a one-way inlet valve. This inlet will connect to the main water tank via a hose.

Make a magnetic coil out of a Ferrite Toroid Coil Core (National Magnetics Part No. 995; see reference) and fine grade copper wire. Coil at least 250 turns of wire around the coil core. Mount the coil core inside the second CPVC end cap. You'll need aproximately 550 feet of "double build" (extra heavy) insulation, 23 AWG wire. Cut support tabs for the magnetic coil out of a sheet of CPVC and secure them inside the end cap with epoxy to support the coil.

Drill holes in the end cap containing the magnetic coil and install a pressure relief valve, a feed valve to connect to the the carburetor via a length of tubing and a valve for the pressure indicator inside the instrument panel. Seal the end cap to the top of the hydrogen generator housing with epoxy.

Mount the generator inside the engine compartment based on the shape and layout of the engine. Connect the electrode wires to the electronics system, the hose to the water tank and the hydrogen feeder valve to the carburetor adapter.

Tips & Warnings
A detailed project manual on hydrogen conversion systems is required to complete the hydrogen generator system (see resources, references).
If there is no room in the vehicles engine compartment for the hydrogen generator, mount it in the trunk, or under the dash.
Don't use cheap tubing or sealants to build the generator housing, the system efficiency will be greatly reduced.
Do not use a larger diameter CPVC pipe. It will not offer adequate safety against rupture at high temperatures.
