Scientist's/Engineers can you advise/help please?

One thing you can eventually do is compare what you are
finding in rain water with what happens in distilled water.
Or with distilled water with some small measure of electrolyte
(acid or base).

Water from all natural sources has unknown chemistry.
This prevents repeatability by anyone else. Lets say
you find some behavior that is unique and potentially
valuable. Without knowing how what you are doing
effects a constant you risk creating non-repeatability
in your own experiments and potentially a high degree
of subsequent frustration trying to find it again. When
the next guy tries it, and it doesn't work because of
unique local chemistry you will be left with credability
problems. Sound familiar?

It sounds like Darwin at its best

Hi Mark,
It certainly does - I took you advice and used distilled water with a little baking soda & found this cell is most economical at 4v/00.25amp (as opposed to 13.85v/00.68amp - max with my power supply), same solution.
I also tried adding extra transition rods (outwith the inner core) in series... they drained the inner core... not what I hoped for, reckon they have to be inside the cell for the reaction??

Hello again everyone - thanks for your info...
I have a few questions... no pie in the sky please 
1) What would be an reasonable efficiency (%) output expected from an HHO cell... Just an average example... couple of plates/tubes, some electrolyte I/V...
2) The cell I've built holds 2/3v for 10min+ after shut down, cables disconnected... it will gradually drop away, quite some time after... it produces minuscule bubbles during this time which like the Voltage gradually drop away (I'm aware the bubbles might just be what's clinging to the walls of the cell).
My question is... Is this voltage/I spurious (unusable), or can this voltage/I be regarded as a constant... If I'm using 5v at 1amp and switching (part second) on and off, am I still using 5v/I or am I topping up with 2 or 3v/I... if topping up, should this V/I be subtracted during efficiency test??? That is:- off load =  no v/I   on load = 2 or 3v/I instead of 5v/I. I'm probably being really stupid with this question but it's bugging me?

Hello everyone - I need your help & suggestions with my cell.

I can't understand why it gets no warmer than tepid - 6.48amps @ 6.3volts for over two hour running - it's an absolutely tiny cell - I don't know if it's the Cadmium rods or Titanium/carbon rods or the shape of the cell, but it should be boiling the electrolyte... it's not?

Appreciate your help
