1. some of our people would agree with you … others think the leakage is from one side of a plate to the other … a couple have tried the offset holes and it did not seem to increase efficiency … we are working it from a number of angles … it will be beaten, its just a matter of which way works best and can be implemented at lowest cost …

2. I’m thinking about current leak and am not sure I totally understand it. But, on the Hole-pattern of the plates, would it help to offset the 3 holes at the top of the plate and the one at the bottom, say over to the right, then turn every other plate so that the electrolyte and gas have to sort of zig-zag through the cells? Would this force more current through the plates and less through the electrolyte? Would this restrict the electrolyte flow too much?

3. Well, you got some of it right. Best volts per plate gap is really in the 2v to 2.5v range … 2v is a bit more efficient, 2.5v makes a bit more gas but also generates a bit of heat … but in that range is considered optimal …

   there is a document on the internet that should be most helpfull to you in answering some of your questions … do a Google search for “D9.PDF Bob Boyce” … grab the D9.PDF document … study it … excellent turtorial …

4. I’ve copy your dry cell but decided on a 5N6; like Zero is showing. The first test produced 2.14 l/M using 270 watts. I’m good with that but I still don’t fully understand how one designs a cell.
   You mention:
   Source voltage that determines plate,wiring
   Desired Amps
   Cell configeration
   Amps draw per in2
   1.2 – 1.4 vdc between neutrals.
   How does all this fit together in a cell design if I had to dream one up?
   Great job EBN is doing. I’m a fan.

5. yes this cell is mainly for learning, and testing which requires main different wiring schemes, a purpose built cell can and more than likely will incorp. bolttype connections. remember each terminal sees relatively low amps, on a 21 plate cell that draws 35amps the most a single connector sees is half of that, which is about half the connectors rating, which should be considered the max for a ss connection. derating for ss is important

6. you have a good argument … and its one we knocked around a lot … the quick connectors we suggest for making the electrical connections are certainly not ideal … it was purely a compromise to make it easy for the experimenter to reconfigure the device on the fly … once you have a setup you like, we suggest that the connections be permanently soldered … we considered other methods such as you suggest but there just aint enough real estate … we are working on it though …

7. the only part i dont like about the ebn cells is the small space in which to hook up an electrical connect, maybe you would just put some washers in between the plates your connecting then a bolt and tighten together like that.

8. well I sometimes forget that everyone hasn’t been around for the whole ride, so I tried to forget I knew anything and explain the basics. well get into Ebn product specifics soon, its hard to break away from testing though:)

9. Hi D3,

   I appreciate your easing into it – you probably did that for me anyway right? After all I’m not the sharpest knife in the drawer.

   ;)

   Still, you all have done some outstanding work. You have my respect & feel free to ‘school me’ anytime.

   Sincerely,

   Steve aka AH

10. Well torque specs and tighting pattern will be another video, this was more of a design talk, than a specific instructional. Sheesh, man I guess thats what happens when your always checking data and results, people love to find what ya did wrong :Pj/k I know what you guys are saying. I want to ease into it.

11. Follow the link in the description then click on the Reseller Information for a list of authorised dealers :)

12. Maybe D3 gets a bit of stage fright when he is in front of the camera?

    ;)

    Still I really like the cells – I am thinking about getting one, but I’m first going to get my booster working (work out the kinks & hopefully get increase in mpg). After that I want to get this dry cell & try it.

    BTW thank all the guys at EBN for their hard work (builds, tests, etc).

    AH

13. ya’ know, its funny you mention that … D3 has the one nagging the rest of us that it should be done that way, and what he do but post a video showing how to do it incorrectly … some guys !!!

    But you are quite correct … star pattern on bolt tightening is the rule !!! even torque and it dont take much pressure to seal … if you run them in too hard, you distort gaskets …

14. Nice vid.

    You might want to tighten the bolts/nuts as you would a spare tire (in a star pattern). That way your pressure is distributed evenly over the entire end plate/s.

    Good stuff & keep up the good work.

    AH

15. Nice job.

16. im still curious about where to find the gaskets for this cell setup.
    am wanting to experiment with that design.

17. with a small device in the 36 plate or less range, not much tourque is required to firmly seat the gaskets and keep the device from leaking. It is best to check for snug bolts often when the device is new. Once its settled in for a bit, they appear to not to require additional tightening.

    The larger the plate stack, the harder the gasket material should be. SmartScarecrow has learned this lesson the hard way with his 101 plate monster device. He will get it sorted out.

18. very nice setup ? Do you think the gaskets squish down to a closer distans after torguing down ?

19. GREAT WORK!

20. Located…. I meant to say

21. Sweet, where is the “buy it now” button ocated??
