Frank Gordon's "Lattice Energy Converter (LEC)"...replicators workshop

  • Two more attempts at plating with Acid.

    These attempts used higher voltage than previous attempts and weaker acid solutions. Power supply was set to maintain a fixed voltage rather than current.


    #1

    - Set volts to ~ 1.84 Volts and added acid to bring current to 2 Amps

    - Current dropped to .92 Amps in 5 hours. Gray coating just starting to form

    - dried with paper towel and it read 10-20 mV but dropped to 000.0mV when dried with a 60 watt lamp for ~ one minute

    - back in tank, moved anode closer to maintain 2 Amps

    - after 7 hours total time, very shiny but coarse, dried and LEC read 000.0 mV


    #2

    - fresh solution ~ 80mL acid in 1.5 L water

    - brass plate ~ 2 inched from heavy iron plate Anode

    - 1.37 Volts @ 2 Amps

    - no coating after 1.5 hours increased volts to 1.5

    - no coating after 6 hours so upped Voltage to 1.64

    - no coating after 12 hours so upped voltage to 1.84V

    - left over night, very heavy coating with coarse particles ~ .5mm in size(colour very shiny, chrome like) some clumps could be rubbed off with fingers.

    - dried with towel and lamp and LEC read 000.0 mV


    Some observations

    - All trials so far will read some low voltage 2-20 mV or so if the WE is damp. Condensation can often be seen on the CE plate when this occurs.

    - When dry no attempt so far has read any voltage at all.

    - lower currents and voltage ~ .2 Amps, 400-600 mV yield smoother gray to dark gray plating with magnatite

    - higher current and voltage over >1.84 Volts plate very fast with a coarse bright shiny coat, no obvious sign of magnetite



    Left: ~ 500 mV 200 mA Right: 1.84 Volts 2 Amps

  • Thanks for the update Ken. In my opinion I think you should dilute your electrolyte by 50% and go again with a target voltage od 2.5-3.0V so that you can see the hydrogen bubbles flowing freely off the surface of your plate. I am still up to my neck with lab rebuild ( and rewire, repaint, re-calibrate everything) but hope to do a few more tests next month.

    Hi Alan,

    I have found with low dilutions and .4 Amps fixed I can see tiny bubbles start to show at .7 Volts with the intensity increasing as Voltage is increased. At Currents in the 1-2 Amp range and Volts over ~1.84 I can see what looks like smoke (micro bubbles) in the solution at the top of the CE streaming toward the Anode vigorously. At 4 Amps and 2 Volts plating forms in minutes.

  • This is only a thought and I'm not at the moment doing any experimentation, but if you used switched polarity DC so the anode / cathodes are switched like every 5 to 10 seconds, so hydrogen is generated at a electrode then they're switched and hydrogen is then trapped by plating, don't know just an idea. Or if you had 3 electrodes and they were alternated with a donor electrode to provide plating without stripping plating off the plated hydrogen electrode so building up trapped hydrogen layers. Full of them this morning.

  • Ken, what about rusting of your samples?

    My active WEs rusted in a very short time (less than one day, with first visible signs just after few hours). Inactive or "less active" ones took longer (few days).

    Also rusting was not uniform in active WEs, it started soon in few points then spread more slowly to the entire part. I think other described something similar.

    Oddly I have seen very little rusting of my plates, some are 2 weeks old and they still all look ~97% rust free. The samples coated with the acid electrolyte have a bit of of rust in spots more of a discoloration, the Alkaline ones have no rust at all. The Steel anodes rust quickly when removed from the solution. Pure Iron as opposed to steel is known to be less prone to rust. The relative humidity has been between 35-45% lately which may have some impact on the amount of rust..

  • That's my ffnding too- the HCl plated items rust pretty quickly.

    I need to clarify. There is very little rust on the acid WE plates after one week. Slight discolorations only in small spots. Most of the coating is still shiny. They look the same today as in my post #981. The Steel Anode forms rust when removed from the solution very quickly but not the CE. I am not sure why my WEs do not seem to rust as yours and Stevenson's did?

    Video could not be clearer Ken. Thank you. This is what we are all about. Hopefully those having success, including Frank Gordon, can help you, and magicsound succeed. That would make this summers ICCF in Silicon Valley all the more special.
