Hydrogen Generators

Does anyone know how to test for output quantity of HHO gas from a Hydrogen Generator when connected to a vacuum such as your intake manifold? The output is easy to test when just checking with a submerged bottle with the generator running on its own without being hooked to a vacuum source. The generator will put out substantially more volume under vacuum than when not. How do you check for output volume when under vacuum? Pylgram

. turbine meter?
. I doubt that the slight difference in pressure will have much effect on output. A quick search didn't turn up anything on the effects of pressure on production, but it seems to me that current would be the major factor.

Thanks for your comment Nacho There is a very big difference in output when connected to the vacuum source at the intake manifold. To demonstrate you can watch the hydrogen being formed with just atmospheric pressure and then connect it to the intake manifold and you can see a huge amount of more hydrogen being made. My search is for the method to measure how much hydrogen is being formed and delivered to the intake manifold while under vacuum is something I haven't been able to locate yet. Thanks for your reply.

Is more hydrogen being formed? Or are the bubbles simply larger because they're under vacuum?

Thanks for your comment Tool The bubbles stay the same size. You can tell the quantity of gas increases when the vacuum is applied. All the vacuum does is suck the gas out of the generator so the generator can make more gas without having to push it out of the generator. I think the next poster may be onto something that might work. Thanks for your post. Pylgram

AFAIK, the ambient pressure might have a slight effect on the electrolysis process that breaks the covalent bonds holding the constituent atoms together.

But you don't get anything for free. Any increased gas production will be offset by the energy required to maintain the vacuum.

Just for fun, I searched for "water electrolysis vacuum", and checked out the "evidence." No one ever cites any concrete, experimental data--they just use phrases like "you can see the difference."

gmoon Thanks for commenting on my post but you didn't address my question. Only goes to show how new this HHO Technology really is. It seems that some people are trying to appear intelligent without any knowledge of what they speak. The energy you referred to is supplied by the engine and has nothing to do with producing hydrogen. Supplying the energy is not a problem. My concern is; How to measure the output under vacuum?

hehe. You're pretty typical, responding with the personal attacks. Just give us science, not BS.

-- There's nothing new about producing H + O via electrolysis. Nor about using hydrogen a fuel.

-- You can't achieve a vacuum, and still produce the gases. If you're producing gases, it's not a vacuum :-)

Indeed, the greater the output, the harder it is to hold a vacuum. So theoretically, higher gas production makes the system less efficient..(if it worked at all.)

Here's how to measure the gas production:

1) load the cell with water
2) lower the pressure by pumping the gas output into a pressure vessel
3) wait until the water is reduced by a measurable amount (weight the cell to be precise.)
4) have the pressure vessels analyzed for purity by a lab.

I can tell you one thing for sure: Water vaporises (evaporates) much more rapidly in low pressure environments. That plus the H + O gases would expand (not increase in amount), resulting in a much greater surface area and more vaporisation.

When you check the vessels for purity, you'll find a lot of condensed water that wasn't separated at all.... Sure, there might be a slight increase in H and O.

Your flow gauge alone will give you a wonderful result--but it won't tell you that much of the volume is water vapor. And it won't measure the pressure within the flow. You'll get figures like 10, or 100 times the production--and they will be bogus (gas / vapor expands to fill the partial pressure vacuum.)

gmoon Appreciate you comment. How did we get from measuring volume through a vacuum to having a pressurized vessel analyzed for purity by a lab? There has to be a scientific method of measuring hydrogen production under vacuum without having to pressurize it and send it off to a lab. It might be as easy as I don't know that's why I'm asking.

If you're trying to hold a partial vacuum (the best you can do), then the gases will exit the electrolysis cell through the vacuum pump....which is ideal for trapping and storing gas. There are other ways of collecting them--balloon, inverted container in water, etc. Ultimately, you'll learn more if you have them chemically analyzed. Isn't that the goal?

gmoon What vacuum pump? The engine creates vacuum while it is running and sucks the hydrogen into it. No. The goal is to measure the amount of hydrogen going into the engine from the vacuum source. If you don't know how it is done then you can't BS your way of explaining something you don't know. No matter how many words you use to make a full circle to get back to the original question, it remains the same. How do you measure the quantity of hydrogen being produced in a vacuum? Pylgram
