Hey guys I had this idea for a new cell concept. It would be made of 2 sheets of SST foil wrapped around a 1/2 inch CPVC pipe with 3M 2-sided mounting tape for a spacer. It would be wrapped all the way around to make sure the spacing is the same throughout the coil. That means that the water intake would be in the center of the coil and the water/hydroxy exit would be at the outside of the coil. The CPVC pipe would have slits cut into it to make an entry for the water into the coil cell. It should probably have a pump pushing water into the cell to make sure the hydroxy is going in the right direction. I was also thinking of tapering the coil up so that the hydroxy naturally propagates towards the exit.
I am not sure if the 2-sided mounting tape will hold up to water and electrolysis for long periods of time so it will be secured with epoxy or caulk on the ends of the coil. I also have a concept in mind to feedback the extra water to the reservoir from the bubbler, it would also insure that the bubbler has the correct amount of water and if there is a leak it would provide a safety switch.
The reason I came up with this concept is because the cost of SST foil compared to plate and tube (cut to length with precision tools) is huge per square inch. Also since foil is so much thinner (.002") it would take up a lot less space for the same amount of square inch electrode area. And yet another benefit, it would only be 2 electrodes but there would be production on both sides for nearly the entire cell (except for the outside and inside of the coil).
I included a concept picture with legend, please let me know what you think and if you have any improvement suggestions. I provide this concept freely to the public so feel free to experiment with it.
