Saturn SL1 Hydrogen Project Part 1

Posted or updated 11.10.08 by Chuck Russell


The very first thing you will need to do a hydrogen-hybrid conversion to your vehicle is the Hydrogen Generator. The assortment of hydrogen generators are extreme, and range from the totally ridiculous mason jars with bare wire electrodes made by students on a budget, to the equally ridiculous priced computer controlled models that fleet truck companies have installed on their vehicles. Such models can cost upwards of $10-K and need dedicated computer programmers to function. You would have to save a lot of money on gasoline to recoup your investment with such a system.

After much study and homework, I decided to buy a single cell hydrogen generator made by Smith Industries called Hydro Super 2. I liked the fact that it was a large single metal tube with 3/8 inch stainless walls. It was a design that has been around since 1984, back when gasoline was cheap and nobody really cared that much about getting the most miles per gallon they could. It also is a proven design, and safe. I recall seeing the pictures of the Hindenburg, and let’s face it hydrogen mixes with anything having only 1 electron. The Hydro Super 2 seemed to be ahead of the other designs, in that the hydrogen stayed submerged in water until it was actually ready to be used by the car. That makes a spark arrestor, or flashback valve unnecessary, and the water bath that the hydrogen goes thru cleans, and at the same time cools the hydrogen making it denser and more potent.

Hydrogen has three times the power of gasoline in equal amounts, and it burns much faster, and at the same time cooler. In addition it will literally clean carbon and other deposits out of your head assembly and cylinders. It is equal to 124 octane gasoline. There are no by products of burning hydrogen, so your emissions are much cleaner when   mixing with gasoline. There are two parts hydrogen and one part oxygen, so another by-product of hydrogen generators is oxygen. If you look closely you will see two large bubbles which are hydrogen, and one small bubble which is oxygen come up the tube together into the water bath. They are then sucked into the engine by the tube attached to the top of the water tank. This all sounds very complicated, but trust me it isn’t. You only need to do about six steps, even the boss can do that.

The Hydro Super 2 single cell model cost me $369, and included everything needed to get the hydrogen generator running. That’s a good deal in my book, as in the four months I have been using it, I have saved a lot more than the cost in gasoline, and it’s been a lot of fun. The hydrogen will make your car run faster at high speed, and easier at idle.

If you look closely at the picture, you can see what looks like a white square block with a tube attached below the headlights of the Saturn SL1 which is my first hydrogen hybrid conversion. The hydrogen convertor is almost 15 inches long and roughly 5 inches wide. It is mounted under the car and extends to within 8 inches of the ground. It is connected with a large metal clamp ring running around it, and L-clamps at the bottom. The bottom has a spigot for draining, or changing water. It will run on any sort of water, but it’s best to use steam distilled water.

There is one hose on the bottom of the hydrogen generator from the plastic water tank, and one hose leaving the hydrogen generator that you can easily see in the picture coming back to the water tank. That hose carries the hydrogen and oxygen bubbles mixed with the water. It functions like a water pump, and is connected to the car battery. It’s quite simple, and very rugged.

The hydrogen generator uses roughly 3 ounces of water every 125 miles. That is a lot cheaper than gasoline. I buy steam distilled water for 92 cents a gallon at the drugstore. One gallon can take you 1200 to 1500 miles.

If anyone is interested, you can see the Hydro Super 2 making hydrogen bubbles on There are many videos of it working there.
