HHO Systems?
Hello! I've heard some people who work in sustainable technology fields say that there are some good HHO Systems (Hydrogen Injection) that will bump up your MPG's. Has anyone here had any experience w...

The risk here is adding water to hot metal of your engine,, This promotes corrosion (Rust) and can lead to early engine failure. THat is a major risk, with major cost involved.
Water injection has been used in the past in military aircraft. When maximum power was required such as during takeoff, water was sprayed into the intake to prevent engine knock.
Besides the heat, the byproduct of combining the Hydrogen and oxygen is water, which will be in the form of steam. Unfortunately, the energy released will be less than the energy required to convert the water to hydrogen and oxygen in the first place. Unfortunately, those basic laws of thermodynamics you learned in high school rear their ugly head and keep this from being a free energy source.
Backyard mechanics often used water injection as well. My high school car was a 66 impala that I put a supercharger on, and water injection as well trying to be able to run a little more boost without breaking things.
Besides piston engines, the military also injected water into turbine engines such as the early KC-135. The steam would help in generating more thrust for takeoff with heavy fuel loads. The system was a pain to maintain, with the crew chiefs having to periodically run tank heaters through the cold nights on the alert aircraft so that the water in the water tanks wouldn't freeze.
