I asked this question in auto, but it might belong here.Has anyone tried this, is the science sound?

Question

Anyone try one of these HHO or "Brown gas" kits?

I have been seeing these instruction manuals popping up all over the place to convert your car to a water gas mix that greatly improves your millage. Saw a news clip from fox of a guy that was using the process to run his car,also as a welding procedure. From what I can gather he is actually in negotiations with "someone" over the process. I also know that the tech for it has been around for awhile. What I am asking is if anyone has tried out on of these manuals that are all over the web. Does it work? I was thinking of trying it out on a second hand lawnmower first in case it ruins an engine. Please if you have not tried it out or dont know what I am talking about dont give me the " well if it worked carmakers would be using it " answer. Any other opinions or thoughts would be appreciated. First hand knowledge even better. Thanks. I will try to respond back later to everyone.

Answer 1

HHO refers to oxyhydrogen (Brown's gas), which is just a mixture of hydrogen and oxygen gases (H2 and O2).  It is easily produced by electrolysis, and has some useful characteristics for welding as an alternative to oxyacetylene and other welding fuels.  But more energy is consumed by the electrolysis process than can be captured from the combustion reaction.  That detail busts the myths of the hoaxes listed in the second reference.

Electrolysis can be useful for powering a car, see the third reference.  I don't think it has been commercialized yet, but the idea is to use photovoltaic panels to generate electricity, then use that to electrolyze water, then store the hydrogen chemically as hydrides, then extract the hydrogen from the hydrides to power the car.

See the fourth reference on the six-stroke engine for a real way to use water to improve the fuel efficiency of an internal combustion engine.  Simply put, it adds an extra two strokes to the traditional four-stroke-cycle engine, injects water into the hot cylinder, and makes it a steam engine for that cycle.  Perhaps some day the extra efficiency will be enough to make up for the added costs in materials and complexity.

There are also ways to improve fuel efficiency by adding water to the fuel, a carbureted air-fuel mixture, or the cylinder during combustion.  So far, the new problems introduced by doing this have outweighed the gain in efficiency.

Answer 2

scientifically sound the only problem is HHO burns at a higher temperature which could cause engine parts to well melt basically.  This can be solved by porcelain plating the pistons.  and you need about 10 liters of water to run your car entirely on HHO.

Answer 3

Everytime the gas proces go up some nutcase starts some product which it supposed to help gas mileage. None woirked in the past and none will work this time around.

Answer 4

HHO?  Usually written as HOH, H2O, and commonly called water?   It doesn't burn.  People have been selling this snake oil since cars were invented.  Putting water in your engine has never been especially good for your car.  There are other fuels that work.  They're more expensive than gasoline.  Theoretically, adding something that doesn't burn, like water, will use some of the waste heat in the engine, expand, and provide some power.  But you're doing that pretty much by adding air....   it really is just another way for somebody to make money from people who don't know any better.   There are many taxes on stupidity..

Answer 5

I was trying to find the article on this on freeenergynews.com, but they talked about the true aspects adding this technology to your car. Basically it said that you might see up to a 35% increase in milage, anything (advertised) above that is impossible due to the limitations of efficency of a combustion engine.

They also said that in order to make it work properly you have to get into the car's computer and adjust the timing to adjust the fuel to air ratio otherwise you are just pumping the HHO into the system and it won't really help.

It seems you would have to change your oil more often since HHO produces more water vapor in the system. And it would probably be best if you used some type of synthetic oil to counter this issue.

Sorry I couldn't find the article, but you can look up tons of info on the web address below. You have to be careful with this type of stuff there are a ton of rip off artists out there and they only increase when people are feeling the pain like they are at the pump right now.

Answer 6

HHO, more commonly called H2O is required to be separated into its parts prior to use.  This requires energy.  The law of conservation of energy says energy can neither be created nor destroyed in a closed system only altered in form.

This being said, I know of nobody that has a process where you apply a given amount of energy to a substance, then extract energy and get more than you started with and end up with the same substance. (water)

I have run across a design where aluminum is burned under water.  This makes Al2O3 and H2 which will run a car.  Currently, with the cost of aluminum this equates to a fuel cost equivalent of about $2.50 to $3.00/ gallon.
