Running an internal combustion engine?

[ZeroFossilFuel]

@IH - In the short time that you've known me, have I ever given you the impression that I'm a quitter? I am, however, in need of some ideas and not afraid to put it to the group.

If anything, I routed the tube too perfectly in front of the butterfly, in line with the air flow. I think maybe inserting it more at right angles to the air flow and facing an angled opening downstream as per Yikes may be better. Better still might be to leave my tube the way it is and flare the end or put a tiny funnel in the end, wide end toward the butterfly. The sudden increase in velocity around the lip of the funnel should create a dynamite vacuum signal.

Sorry man I did not mean it to come out like that . I meant more about quiting on the hook up because the outcome was not working  with out  seeing why you had no vacuum where all gasoline cars that run correctly  should have high vac under these conditions .

Again I was not calling you a quitter  . The fact is what you have done for this forum is rather fantastic and I have to thank you for that . The step by step build you are doing has my highest praise .

The  tube must point to the butterfly as shown in the design as well.

Also  the flare idea works very well to increase vacuum along with a slight angular cut .

I don't know if you saw my latest youtube video last night but it appears the S-cell generated about 1 LPM @10A. There was still quite a bit of leakage around my original gasket. I'm sealing up the removable lid tonight by gluing a frame to the top lip of the tank with a more pliable gasket, much like the drawing you presented except that the frame hangs over the interior of the tank, not over the exterior edge. Still leaves me room to remove the plate cavity, etc etc etc.

I cannibalized a check valve last night because, with it cut off the way I did, it resembled a mini funnel with an large dimension about the size of a nickel. Stuck that in the tube inside the air duct with the wide end facing the butterfly. It managed to pull about 1" Hg. I would be VERY interested to see reports from others of their measurements taken from just this location, no other plumbing, and exactly how they did it if they can get more than I just did.

To experiment I will be enlarging the size of the funnel to raise velocity even more at the mouth of the funnel (ie drop pressure). I will also be testing various forms of tubes inserted at right angles to the air duct as I have seen elsewhere with the wedge cut facing downstream and see how well THAT works too.

I realize the S-cell is a teaching aid. 1/4" spacing really is too far for lower voltage applications. But is does make it easy to get a good look at what's going on and provides a common platform to compare notes with. Soon I'll be ready for a PWM supply. I'm sure you can point me in the right direction to get me off to a good start.

And just wait until you see the design I'm cooking up for a finished electrolyzer. 3 times the plate surface area, 3 times the circulation velocity (maybe more), 1/6 the leakage current per square inch of plate surface area. Closed circuit cooling. I can't wait to see the numbers when I flip the switch.

Two questions here: Where's a good place to find SS wool? and what size works best?

SS  wool , grocery store . Just pack the bubbler with it, loose but evenly .
Keep up the good work and looking forward to the next builds.

AKA pot scrubbers.  Also a trip to a machine shop scrap hopper when they're cuttin' stainless.
