Personal test cell. 12in electrodes

Yes,
but don?t put it directly at the top,
just use a plastic hose to it, but don?t use a bubbler
between it.
I still did not find a right vaccuum pump,
which can suck explosive gases without danger...
if you find something not too expensive, please let me know.

I would prefer a pump just only made out of plastic, not metal
for safety reasons..

Many thanks.

Well what about the venturi vacuum from an carburator as the vacuum pump?
How many more bubbles are we talking about anyways??
I diddent think stan meyer was on the basis of vacuum...

I haven?t had time to test any real vaccuum pump yet,
maybe something simular to a rubber plate inside like  pump
like a bubbler pump for aquariums ?

Have to agree with Harti here guys, putting H2 and O2 under pressure is extremely dangerous - and I'm not really sure why you would want to anyway.

The mixture of H2 and O2 is far more unstable (and explosive) than H2 by itself.  If you research the subject you will find that containment of theses gases together requires very specialised equipment and even then is not recommended.  Even just rough surfaces are enough to cause ignition.

Don't do it, someone could get badly hurt! And, afterall the whole idea of hydrogen on demand is that we don't have to contain and carry about vast quantiies of explosive gases.

The faster we can draw this gas off our wfc's and into the engine, the better.

That sounds great and all... the whole, "on demand" part. But I dont think it's possible with these cells we are building.
It would take at least 100lpm of HHO production to power a SUPER SMALL car. These cells cannot produce enough gas on demand to power a V8 which would require around 100lpm of HHO gas just to idle it at 900rpm.
How many Liters per MIN are you making?  The most I have seen so far is 4.5LPM
Not even close.
