Now that many of us are producing ignitable HHO, I thought it might be worth our while to figure out how to separate the Hydrogen from the Oxygen, and then feed in just a dim amount of Oxygen back into the mix. This produces HHO again, but a far more powerful HHO. Comprende?

Anyone got an idea on how to do this efficiently, cheaply, and as safe as possible? Sure, nothing is ever safe, but as safe as we can be here.

For instance, and I'm going out on a limb here with probably the wrong assumption, but if you use a reverse osmosis filter membrane in the top of a box, and you shoot HHO into it at the bottom, I'm guessing here that perhaps the hydrogen will force its way through the filter into the top of the box, while the oxygen would be held back somewhat. And why? Well, hydrogen wants to shoot upwards, but oxygen is heavier. Sure, some oxygen might bleed through the membrane, but hydrogen will force its way through much harder. So, this might, and again I'm going out on a limb here, produce a richer HHO above the Dupont reverse osmosis membrane, often called an RO membrane. If this is true, then perhaps this is viable because these membranes are not that expensive.

[EDIT: After doing some research, I found I'm not too far off my rocker here with RO membranes. RO membranes fall under the category of "polymeric membranes" and this European Union paper, published by researchers in the Netherlands, reflects on how effective they are. In the end, they said that polymeric membranes will work, but they suffer from swelling (and bursting) under extreme pressure, and that the hydrogen separation worked but was somewhat weak. The paper said that ceramic membranes were the best filters of hydrogen out of HHO gas.]
