No, you have anecdotal evidence. There is a difference.

I have discussed that with him, 90% of the time he uses the cruise control.

If he were doing that before, he wouldn't have been getting 5 mpg. Theres more at work here than the bubble maker.

It just a small (14" cube) that holds a few gallons of water. You have to wire it directly to the batteries. It pulls 20-25 amps. Using $2.65 a gal for fuel, a increase to 6mpg from 5mpg will save $11k a year based on 125k miles.

A constant 20 - 25 amp draw trom the electrical system will increase the parasitic load imposed on the engine by the alternator as it works harder to produce the current being consumed by the hydrogen generator.

There's no such thing as a free lunch.

In a 1.8liter gasoline engine in a car, that kind of draw would be huge. However, in a truck, the load on the alternator wouldn't have enough affect to make a difference.

Nor would the amount of hydrogen created make a difference. One cannot create more energy than already exists from the existing products used in creating the energy. Water and baking soda (at least in the small amounts used in this operation) don't have all that much energy content.

The solution is simple, put it on a dyno.

Say at 50% throttle the truck is putting 180 HP to the ground. Keep everything steady (rpms, throttle, etc)

Now turn on the hydrogen generator. If the HP goes up, it works. If it stays the same or lowers, the hydrogen generator is actually hurting you.

One would think the manufacturers would do this if the product worked, if only for the advertising value.
