How to make a Hydrogen Booster Yourself
(Since you cannot buy one at the Autozone.)

Tools needed : 1) a electric drill, 2) 7/16" wrench, 3) a vise
4) ice chest full of beer, 5) a good brain

You must be a handy person with a shop or garage. You will be tinkering with this thing from time to time. I did not tell you to make one, I'm just showing you how easy it is to make. I'm not liable for your dumb mistakes, Remember safety is no accident. Alot of friends will think you are going to blow yourself up. You are not making a hydrogen bomb. All the egas that this unit makes will be burned up. You will save at the pumps, you will clean out the carbon in your engine, you will pass the SMOG test easy. You will have more power. Your engine will last longer. You will be stoked you did it yourself.

My 3rd cell was 7 Stainless steel wall switch covers. $1.78 each (stole idea from Bryan) and 1/4" SS steel threaded rod and SS 1/4" nuts & washers. 1/4" rubber grommets for insulators. The plates are drilled for 1/4" thread on one side and the opposite side is a 1/2" hole with a rubber grommet in the 1/2" hole. I use 1/4" hose pieces to help space the plates from touching. If the plates touch you get a short.

Beware of the corrosion factor.

See the "New Improved Design"


I used 4" ABS threaded cap & sleeve. I found a 4" 1/4" acrylic pipe, but I recommend a clear water filter housing as pictured below. Make the cell fit your space under the hood. 8"-12" tall. The top thread Stainless Steel (304 grade) is positive (anode) and the lower threaded rod is negative. (cathode) I used 7 switch plates and went (-+-+-+-)One more cathode to produce more hydrogen than oxygen. You get 2 H to one O.

Wiring Diagram

Start by drilling the SS switch covers , stack all 7 and drill at once. A drill press is best with those gold tipped drill bits. Drilling stainless gets hot. I drilled out the screw holes. One side drill a 1/2" hole and the other side drill the screw hole with a 3/16" drill bit and then use a 1/4" tap for the threading of the 1/4" SS threaded rod, two 12" long SS threaded rod will do. Put the 1/4" hole. 1/2 OD rubber grommets in the 1/2 holes for insulation. Bend the rod 90 degrees in a vise about 4", you can always hacksaw them down later. to fit into the clear filter housing. The clear filer housing can take the boiling temperatures. In the summer this unit will get hot! 12 volts & 10-25 amps will get it hot after 15 minutes of driving. Peter says you only really need 2 volts, but the more amps the better. I don;t have 2 volt circuit hooked up. I just use fuses and a auto accessory relay for $5.00 at the Autozone man. I also hooked up a simple DC pulsar to make more egas. It does make a little more egas. A simple solder kit for $9.99 plus shipping.

This cell ran for about a year. I used SS
screen for the cathode (-) hydrogen gas & just 1/4" rod for the anode (+)
I figure the screen would take place of SS discs with many holes drilled. The egas seams to come off the edges of the SS (stainless steel)

Before photo and one year later.
The unit will make red sludge that
you will have to clean out once a month.
I made mine to take out easy.

Simple Wiring

One side (cathode) (-) is grounded to the car's frame the other (anode) is hooked up to a 25 amp fused thick wire (10-12 gauge braided copper wire, buy a spool at the auto parts store), 12 volts (+). I hooked up a simple auto accessory relay ($5.00) and a dash mounted switch ($5.00) What the relay does is, it allows the switch to get an 1 amp or so, current , while the relay turned on takes up to 25 amps coming straight form the battery (+). This way you can use a 5 amp rated cheap switch rather than a 25 amp switch. Remember the more amps the thicker the wires need to be. DC needs thick wires or you start to lose amperage. To have efficient egas, you only need 2 volts, the extra 10 volts does nothing but heat up your cell water. I'm no electronic wizard, so I left it simple. There are circuits on the egaspower yahoo group files. I say "join today and learn all you wanted to know about running a water powered car.

DC pulsed motor Controller
A simple solder kit for $14.95 plus .99 shipping. It can take 12 volts up to 25 amps, it has a 555 mosfet that pulses the signal much like AC does already. The pulsing action at the right frequency (about 8, on a pot. 1-10) helps in more egas production. The Hydro Booster will work without it, but to add more egas what the hay. You hook up a Pot, to the circuit and you dial it in till it bubbles the most. This is why clear filter housing is good for experimenting, because you can watch the bubble action and show friends. They won't last forever, much like SS 4" pipe would be best for long time applications.

I have a one way check value, so engine by gasses will not come back into unit. So guys complain about backfire, I never encounter backfiring. I have it hooked to the vacuum in at idling and also to the throat of the carb.

Recently Peter added this Brawny Hydro-boost to the egaspower group. He says we all make Baby boosters. If you really want to get great gas mileage, try adding a 1/4" steel line or 3/8 soft copper, from a hole you drill into your exhaust pipe before the converter, and weld in place, or place treaded Jerry rig fitting. Have the air line go into your cell at the bottom so it helps push the egas through to your fuel source. Put a value on the air in, so you can play around with little or alot of bubble action. It's funny to watch, don't blow up. I also will remember the time at the Hwy rest area, during the hot summer on a road trip, I had a distilled water in a clear whiskey bottle., Stopped at a rest area with the hood up filling the cell with water and a black brother walks up and says "what the hell you got there son, feeding your truck old bourbon whiskey, his eyes were wide up and looking and we both could not stop laughing, explaining him the device later, at first I went along with I'm trying to get the old rig drunk I said. He s really thought I was burning grain alcohol in my truck! Then my friend walks up and explains it's only water.

The brawny booster works good so far. I have not checked my mileage lately. You can also install a MAP sensor potimeter and adjust down your air to fuel ratio (14.7 to 1) to (14.7 to 100:1) by turning a dial.
Bypass your oxy. sensor too. Don't try it at home. You can buy the plans here, but not from me. I don't sell anything yet, or may never.
I'm just handing out the hints to be a successful happy fuel saver.

Now the Electrolyte
It's not a atomic separator/fuel cell, it's just a battery.

You got it all installed. With the filter housing you can use 4" 3/8" 'U' bolts from any hardware store. I made a 1/8" steel plate holder. MacGiver it baby. Gerry Rig helped me. See photo above. I use 12 volts with 25 amp fuses as to not burn up my DC pulsar. Peter has 80 amp fuses? Sounds like a breaker box fuse? He uses 2 volts at 70 amps or more. Fill the unit with rainwater or any water, some use distilled, it does not matter, you will be taking it out to clean it up, once your amps go down. Fill up to the top of the switch plates with water and 1-3% KOH (Potassium Hydroxide) from a chemical supply house. You will pay more for hazardous shipping than you will for the chemical. We found this is the best electrolyte, it is a base, rather than an acid. Sulfuric acid works but corrodes things faster. Lye works too, but puts off weird fumes and also attacks and melts some plastics. ALso once you get the unit going you never add electrolyte again until you clean it out. You just add water, because the electrolyte stays in the container and does not separate into H-O gas.

Next. Start the car and drive. A good way to check gas mileage is to fill your tank to the top (top it off) go drive around for a week and fill it up again to the top, at the same pump at the same gas station. So the car is level as the last fill up. Read the gas pump meter for gallons. And there you have it. Miles Per Gallon. Any questions?
