Luther Pollok: Basically, this is a safety improvement for wet cells that do not use a reservoir and have a air gap at the top while running.
Luther Pollok: It may only be 5 degrees cooler, but the heat transfer away from a poor conductor is greater in solution than it is in a gas.
Actually, I am doing this because a loose connection under solution has access to a smaller quantity of HHO gas than a loose terminal at the top of a cell. (the explosion will be much smaller)
The added benefit that any heating produced by the poor terminal is transfered to the solution rather than the HHO gas itself.
Bing Fischer: Great Video Luther!
Are you doing the electrical leads to the bottom to try to lower the temps at the connection leads from the water?
If so, I would recommend you keep an eye on that. From the tests I have done the water below the plates is only about 5 degrees lower than the plates themselves. At the top in an 3 inch deep open air bath system the temps are a good 10+ degrees lower than the cell.
So I would check the connections, rubber and terminals because the heat from power might melt it
I know all too well the limitations of the written word, plus the time lag in responding. it just isn't the same as speaking and body language. It's all good.
You aren't doing anything wrong in this video that I can see; in fact I like several elements of your design. The pop-off fitting, the circulation system and 'no gas chamber' electrolyzer are all A+ in my book.
Cheap, easy and effective wins every time!
Luther Pollok: Thank you very much for the compliment.
Luther Pollok: See my personal email response.
Luther Pollok: I also learned the hard way with the couplers. I like them, but they can be a problem if you don't check up on them once in a while.
Thank you very much for your comments and feedback.
Good luck with your project.
Luther Pollok: I had not seen that. I will need to keep an eye out for it.
Luther Pollok: Thank you very much. I appreciate your observations and comments.
Luther Pollok: The sink fittings 'just came to me' when I was looking to building the bubblers.
I picked one up by mistake when it 'dawned on me' that this was perfect!
A really nice big hole I could use as both a filler cap and explosion protection device all wrapped into one.
I second using the plumber's grease.
Extremely expensive for what you get though. so far I only use it on the PVC screw lids where it would be nice if I could really get those caps back off again when I need to. :)
Luther Pollok: Thank you for all of your observations and comments.
I appreciate all of them, even if at times it may not seem like I do. :)
Sometimes (ok, ok "most of the time") I have to figure out that I am 'doing it wrong' the hard way.
This may be one of those times.
As in turning your bubbler into a handy-dandy grenade? I aggree. So, did you come up with the sink fittings idea? If you did, then good on ya! Meanwhile, I suggest using plumbers silicone grease on the fittings if they seem to be "hanging up". My experiments with it indicate it makes things pretty slippery, ala dent in ceiling.
I was trying to say the bubbles tend to move the water in the same way they do in an aquarium. It wasn't a suggestion to do something different, just pointing out the reason it works.
The reasons for doing so are fine as well.
Luther Pollok: As for the compression fittings...
I want a large "emergency exit" that has a very weak resistance to very fast expanding gases that you might get during a flashback event.
The problem that I see with compression fittings is that you are expecting to be able to have a controlled release of those gases.
I do not think that is possible with a small diameter compression fitting.
Using a small emergency exit point will increase the probability of causing damage to the tank.
Luther Pollok: I don't think I will have a problem with circulation.
That other tank you see in the background circulates very well without any external assistance even when cold.
The purpose of having a separate reservoir is to keep the accumulation of gases away from the plates and any source of spark and explosion hazards.
I am inclined not to inject air into the system near the plates just for that very reason.
charlieehler: The circulation will be greatly assisted by the flow of bubbles, ala fish aquarium. Did you think of using the compression fittings for a blow off? If you did, that seems a really workable idea!
thecellinside: good job luther, cant wait to see it all assembled and running!
littlestpetshopkid: also did you see what i wrapped my cell with (silicone tape called f4 tape or mox nest tape it withstands 4000 degrees)
littlestpetshopkid: you responded to my video with the rubber 4inch coupling the reason I do it that way is because the clean out cap leaks on me with the cell sitting in my car during the day it gets so hot under the hood (engine off summer time 100+ degrees)that I can take off the cap with my pinkey put in the morning it takes a pipe wrench! I used a 2inch heavyduty coupling n it didnt work it kept popping off. this latest design in "trialnterror got hho bro series" seems to work like a charm I have continued----
shamansays: When you get a chance, can you elaborate on the "plates vs voltage" match?I am not familiar with these two being an issue with each other.This might explain some mysterious complications i have been having.
