I don't care too much for Freddy's theories, although, he did show what seemed to be his truck running fairly well with a simple and cheap modification to the vehicle. It appeared to have run on HHO of typical popular designs of recent times. What is not well known is he also added some gasoline to the water. At first, your knee jerk reaction would be to dismiss him altogether, but, when you look deeper into what he was doing, you may be able to realize he had done something old yet new and possibly very inexpensive to build using only the technology most of us have been using already for our own tests and so on. He had solved a problem that has plagued HHO researchers for years by simply adding a little gasoline to the mix.
You see? What Fast Freddy may have done is most ingenious! What may have come off as a blunder could be the revolutionary design all of us have been searching for. A milestone in the history of HHO research. I hate making predictions, but, I think this may catch on soon and be a popular modification for HHO enthusiasts and alike. His design is easily replicated since he used the same ideas we have all been using for the past decade or more. He just changed a few parameters.
Here is how it works... the cell is a typical "Stan Meyer" type multi-tubular cell, with a PWM and all the other doodads like pressure valves and flashback arrests. Contents of the cell consist of 80% water and 20% gasoline. Freddy claimed 2%. But, 80% water is still damn good on savings in gasoline. Remember, gasoline engines can run very efficiently on gasoline vapors, reducing the consumption by at least 80%. But the problem of overheating soon will overtake the engine without proper cooling such as water injection as used in the days of the war. On the other hand, HHO does not have enough energy to produce the same thermal output as gasoline, no matter how much we can cram in the cylinder before detonation. HHO simply does not have the energy to run any motor or engine at full throttle with a load in normal conditions. In short, HHO has no torque. So, gasoline vapors are too hot, and HHO is too cool, but when we put the two together, things seem to work out just right. Hence, Fast Freddy's HHO, gasoline vapor, and water injection system. Basicly, it's a $500.00 DIY system that can save you 80% or more on your gas bill.
