100% money robbing scam.

It, just like EVERY other hydrogen/HHO/browns gas "generator" out there, is a simple middle school level science project that an 8 year old can build. Its simple electrolysis. It consists of a jar, water, baking soda, and electricity. There is NO possible way it is worth even remotely close to the $97 asking price. They are making nearly 900% profit on it!

Review your laws of thermodynamics before you blow money on such major scams. There is no possible way it can significantly increase efficiency or produce enough browns gas/HHO/Hydrogen gas without consuming more fuel to generate the required electricity.

Electrolysis is very inefficient. It takes more energy to drive the alternator to make the electricity to do the electrolysis than you will get back from burning the hydrogen as fuel.

Simplified math of cycle.

Electrical generating efficiency of alternator roughly 93%
Electrolysis efficiency 70% ( a very high value obtained through actual experiments )
Diesel cycle efficiency 54% (highest ever observed in actual engine)

Now lets take 5Kw of mechanical energy and run it through the hydrogen generation cycle.

5 x .93 = 4.65 Kw of electrical energy
4.65 x .7 = 3.255 Kw of hydrogen energy

Now lets run that through the diesel cycle

3.255 x .54 = 1.758 Kw of mechanical energy.
So basically, you use 6.7hp to produce 2.36hp using a really old and obvious piece of technology.

So in the end the most you will ever get back about 35% of the energy you expended making the hydrogen.

Conclusions: Losing proposition.

Anyone that pays actual money for scams like that needs to retake their middle school science classes. That includes all forms of MPG scams- Acetone in the fuel, fuel line magnets, propane injection, intake tornadoes, special gas caps, fuel catalysts, octane boosters, cetane boosters, electric superchargers, MAF sensor resistors, O2 sensor resistors and throttle spacers.

NONE of them significantly improve MPG and ALL of them simply drain your wallet of money. Fuel only contains X amount of energy, the first law of thermodynamics says that energy can not be created or destroyed, it can only be changed from one form to another. Converting energy into different forms (fuel-mechanical-electrical-electrochemical-mechanical as in the case of the hydrogen generators) results in heat production and energy losses that cannot be regained.

Energy cannot come out of nowhere, if you want to reduce consumption then you need to reduce power demand.
Get all your maintenance up to date.
Use synthetic oil.
Disable your EGR.
Advance injection timing by 2degrees.
Keep the engine at 180*F, no higher.
Use clean fuel from a clean, high traffic station.
Don't gum up the engine with vegetable oil.
Air up your tires to the proper PSI for your vehicle (NOT what it says on the tire sidewall).
Get rid of any unnecessary objects obstructing airflow (spoiler on the trunk lid for example).
Lower the vehicle weight (Remove unused seats, clean out the trunk, don't carry gallons of spare fluids, etc)
Drive 55mph instead of 75mph.
Roll down the windows instead of using the A/C.
If you have a Diesel there are several modifications/swaps that can significantly improve MPG).

I went from averaging 21.1mpg in 06 to 23.4mpg in 07 to 27mpg so far this year by following those steps, driving like a sane person, installing special injectors, installing a higher ratio differential, and improving my turbo's airflow management.
