halfwaterhalfgas
I've been doing some research on this feature found at halfwaterhalfgas.com and I was wondering if anyone has tried this on an expedition yet. There is a local person who has done this on their car and seen about a 30% MPG increase.
What do you think?

Water and gas do NOT mix. They have different specific gravity values. I have a Yamaha 225HP V Max HPDI that protects itself from water in the gas. Water is heavier than gas so if you get water in the gas the gas floats on the water. In the final filter for my outboard there is a float that floats only on water, but not on gas. If you get some water in your gas the float will rise and set off an alarm and shut down the engine until you flush out the water. The last time I checked firemen use water to put out fires not start them.

Oxyhydrogen - Wikipedia, the free encyclopedia
Oxyhydrogen is often mentioned in conjunction with devices that claim to increase automotive engine efficiency.
Many of these claims, prima facie, violate the Law of conservation of energy. See Conservation of energy and Electrolysis of water:Efficiency. To date, none of these claims have been proven, and most have been fraudulent.

Personally I think it is snake oil. I don't think there is enough gas output of these devices to make any difference on mileage. Heck just leave the petrol pig in the driveway and watch how long a tank of gas lasts ya LOL.

OK I think we all jumped on roboteacher about halfwaterhalfgas.com, after looking at web site they are not mixing water and gas as we all know that won't work, so before you comment maybe you should look for yourself. As far as the claims that are made I don't know.

Umm, the last I knew the basic concept behind an internal combustion engine was a small controlled explosion within a cylinder.

A wise philosophy considering that this concept is already in play!

Very true. However, gas is atomized in the cylinder and becomes explosive at that point, in case of this gadget; you have hydrogen mixed with oxygen, traveling to the cylinder, with a lot of spark sources available.

I haven't read exactly how the system works, but I assume it injects the hydrogen at some point downstream of the throttle body, which would be exactly the same effect as a throttle-body injected, or carburetored system works. They all have an explosive mixture of fuel/air downstream of the throttle plates that is distributed to the cylinders via the intake manifold. I can't recall too many cases of people getting blown up using those systems...
