Had this first part of the cell done now for 2 weeks.
Since then, I've been working on a coil winding jig to make the remaining copper coils. It took me 2 hours winding the first coil by hand. And afterwards, it did not have enough "stretch" for the gapping material (.015" fishing line) so it could fit over the tube (Now I use it as a 6ohm power resistor...). With the jig completed, I was able to make the same coil in about 5 minutes. To adjust the ID of the coil I just added regular copy paper around the tube (.005") till I got the desired total diameter. Actually got it right the 3rd time. Now I have 2, 6ohm power resistors!
After researching, and also thanks to some members (Jaxom, sm0kin) here, I am expecting a "solenoid" effect. That is the ionized water will be forced along the magnetic lines. I am anticipating more HHO production from this effect. This effect is know as Electrohydrodynamic propulsion. A mouthful, but it has actually been around awhile. I knew nothing of this effect. My initial concept of coils inside of tubes originated from the need to increase the surface area to it's physical maximum allowed by easily obtainable sources (pipes, coils, screens, etc.). I figured plates are good in one dimension (X plane) so how could I gap in a second dimension (Y plane), and hence the sp1r0 cell.
This now has become a prototype to study the electromagnetic field effects of pulsing inductors with different frequency's. This is a totally different concept than pulsing the tube themselves, which only limits heat buildup.
I will be doing initial testing this weekend as I have almost made the coil winding jig fully automatic. Initially, only tap water will be used, so all the videos you see in this thread, HHO production will be WITHOUT an electrolyte. Eventually, when the final stage is completed, I will remake the cell and test with only distilled water... I believe it will lengthen electrode life, especially since there are two metals in the electrode.
Unfortunately I have no PWM as of yet. That is also in the works. So all initial testing will be 12VDC from a truck battery.
I will keep this thread updated as I progress. All suggestions appreciated!
