Generating H and O separately

[22350]

I am interested in building a generator that will make the two gases separately.  Can someone point me to a link where I can see plans?

This is actually quite simple to accomplish through regular electrolysis.  The trick is to have your tank designed so that at the top of it are two tubes (clear glass or plastic works well) jut straight up, fill this tank with two tubes up to the top of the tubes (water shown as blue in crappy picture attatched) then make sure the anode and cathode extend into the two tubes and are mostly contained within the tubes (shown in red). Oxygen and hydrogen will then seperately rise to the top of each tube and can be collected through a valve at the top (not shown in crappy picture). This only works with DC electrolysis, with ac, you will get an H and O mix.

Im sure it need not be said, but as the gass builds, either it will displace water which needs to go somewhere or it will build in pressure, also, hydrogen is extreemly explosive, cool trick is to let the pressure of hydrogen buid, fill a baloon with it, and light it with a meter stick (distance is for safety) and you will be surprised at the HUGE bang it creates. I would suggest building your tank to withstand the pressure, otherwise the water level in the water level will drop, and less will be in contact with anode and  cathode increasing the resistance, and decreasing the gass production.

First of all, thanks for the extremely quick reply.

I am curious as to why more people aren't creating the gas separately?  Seems that the Dingel model works with this sort of cell.  Also the Hydrogen can be stored (not under presure) without explosive tendencies.

Just seems like you would have better mixture control in an all hydrogen powered engine

One of the main reasons for not creating them separately is that when the gasses are allowed to mix with standard electrolysis, they will be in the perfect molar quantity (quantity of substance measured with number of molecules rather than mass) for combustion without any left over gasses of any kind, meaning complete and total combustion of all gasses involved. However they do not take presurization well without getting water vapor again.

I thought I read on these boards that there was a little less O than needed to optimal combustion.

Don't you run into the problem of not being able to store the HHO gas so that that it can be fed into a carburetor or injector at a controlled rate?  You are at the mercy of the HHO generator.  Also, how do you deal with acceleration? don't you then have to control the level of oxygen to control engine revs? I suppose that you could install the HHO input "upstream"  of the fuel injection system or carburetor.  Seems a little wild.
