To be fair, I did a lot of modeling myself when it came to electric fields inside ionic liquids (via Nernst-Plank) and it is anything but trivial. Although the overall concept seems simple, coupling electric potential with ionic movement inside of a fluid is an incredibly nonlinear phenomenon. The PDE solver I used could barely handle even the simplest 1D cases of the problem. Then, if you choose to involve electrochemical reactions, the potential is no longer transparent and that dynamics of such a situation become even more complex, especially when your reactions couple with your ionic species whose concentrations feed back into the potential which then feeds back into the reactions. Eelctrochemistry is one area where I believe complicated mathematics is all but a necessity. My main issue is that researchers working in this field don't seem to make an effort to non-dimensionalize their variables or lump parameters making the math look messier than it actually is.

I’ve restored about a dozen of the older 2000 series supplies. The build quality in them was amazing! The main failure mode on them is the thermal switch inside the reference oven. They used a simple bimetallic switch to keep the oven at 80c. You can still buy new switches but it requires completely disassembling the oven assembly, which is difficult to do without breaking the bakelite base. I ended up designing a solid state replacement based on an op-amp, SSR and thermistor. You just drill a small hole in the oven base, feed the thermistor up and seal it in with some silicone sealant. The circuit is powered directly from the AC via a simple capacitive dropper. This keeps the oven at 80c +-0.25c, which is better than the +-3c of the original bimetallic switch. I’ve resold about 10 of these refurbished supplies on eBay and they’ve been working for 5 years now with no problems! I’ve got about 5 Power Designs supplies in my lab, my favorite being the 2020B!

I worked on this as an undergrad. Didn’t get anywhere really took me a whole year to fully grasp the mechanisms at that level and my post doc advisor would just assign me the projects that he stalled out on (which in hindsight was a bit unfair) but it was really interesting. We’d etch borosilicate glass like you do silicon to get these tiny channels. Use 20,000 V (very low currents). They had several applications proposed- though when I went back a decade later it seemed little real “big picture” progress was made (tbf I have not reviewed the papers from the group in a very long time). Specifically my post doc worked on doing electrophoresis of proteins in 2 dimensions using the chip. He and the group used positive charged micelles which moved contrary to the field, non-polar proteins would spend more time inside the Micelle and going the wrong way for the first dimension. The second dimension we’d dump in the same buffer minus SDS sufficient to break the micelles. This would make a second dimension separate on charge vs drag. (First was charge vs polarity ratio)

Japanese researchers did build a submarine with a magnetohydrodynamic drive. Inefficient, beyond slow and eventually, the sub ended up out of the water on static display.

I wonder if you can enhance the separation at the walls? LIke having some different electric field there to assist? Not sure if that would mess up the overall flow field though.

Can anyone help me understand how this actually moves the water, and not just the hydrogen? Maybe I'm lacking some elementary understanding, but if the only thing moving across the barrier is hydrogen, then what does it re-combine with on the other side to form water again? This is really cool, I understand the rest of the video for the most part, but I really don't grok the actual chemistry happening at the barrier!

@camperkiller3

I don't definitively know the answer, but I am guessing that it's due to the positive charge of the hydrogen cations attracting the negatively charged hydroxide anions. For example, if an imbalance of H+ and OH- occurs then they will attempt to reach equilibrium by moving together. However the H+ cations are blocked from moving back through the filter by the electric field, therefore it is the hydroxide anions that move.

@a3xccy379

There is no separation in the first place, there is only orientation going on with the hydrogen tail. A true ion does not form. The intact molecule is dragged along by it's tail. As room is made at the positive end for more water, it in turn is orientated and drug along as well. Anions or cations are not involved as in theory they are not formed, but in practice most of the energy used is for that 'side reaction' as explained about woeful efficiency near the end. Also note that there is no barrier in reality, the sintered glass media of the filter is just that much more glass surface area upon which the hydrogen tail is made and used to fuller advantage. Oil forms a similar heads and tails orientation with steel crankshafts for example only there it's the carbon head attracted to the iron molecule since carbon will readily dissolve into molten iron. Silicon loves oxygen like iron loves carbon.

From wikipedia: "The Coulomb force on a charge of magnitude q at any point in space is equal to the product of the charge and the electric field at that point" F = q E Since the force is dependent on the electric field, not the current (other than the obvious current from the flow of charged particles), theoretically I suppose you could have some kind of EO pump without additional current flow. When charging a supercapacitor for example, there is a very efficient storage of charge and energy even while pumping ions over to the electrodes. However to get continuous flow could require a peristaltic effect, with multiple capacitor plates and alternating voltages.

@roboticus3647

If the electrodes were insulated, then the charges would accumulate in a cloud near the electrode. That cloud would essentially shield the rest of the water from the field, so you wouldn't get a good field across the frit filter. When the electrodes aren't insulated, then when the charged ions reached the electrode, then the ion could take or give an electron (depending on which electrode it is), and become neutralized, preventing the accumulation of the shielding cloud of ions near the electrodes.

Could you stack these pumps in series to generate enough pressure to build a hydraulic ram with no moving pumps? I also wonder if this is similar to how pumps work across cell membranes to selectively move molecules (but ATP powered). If glucose and oxygen could be selectively pumped out of blood plasma, then they could be combined in a fuel cell to generate electricity inside the body (that would also power the process). Generating power from blood glucose would have an enormous range of uses.

Also if the OH- was going to move in any direction shouldn't it be towards the opposite of the H+ because it's attracted to the opposite plate.

@jacogomez1093

Not only the H+ moves through the sintered glass, the quimical bond between H+ and OH- is not broken by the interaction with Si (it only slightly polarizes the H+ aligning the water molecule thus creating a "charged extreme to pull") so when the H passes through the filter the OH goes with it. (BTW sorry for my English).

I didn't know glass created exclusion zone water. Well, I knew it did a little bit, but I guess a little bit is enough for this. So I suppose a more hydrophilic material would cause stronger pumping. Also, more light input into the active area should additionally cause stronger pumping.

Dr Gerald Pollack has shown a continuous pumping effect and also current flow to light an led powered by this layer of H2O3 "gel" layer Oh lastly have you tried the water "bridge" a layer of water across 2 beakers that will extend even to centimeter length by the high voltage potential between the 2 beakers. I am so going to have to duplicate this. Kudos on such great work.

Thanks Ben, another awesome video!

Thank you for the great discussion. I have had to explain how 1000 psig across a leak in a heat exchanger will result in fluid from the low pressure side going into the high pressure side. Next time I'll set up the salt membrane experiment and let the engineers "see" for themselves. Also, I really like seeing the way you made the experiment. Well done as always.

Excellent demonstration! Would love to see more of the fluidics design/machining process - I know everyone is crazy for the 3d-printed ones these days but very I seldom see them in use.

This the best experimental physics channel Ive seen

thank you , you teach me more then my engineering college . thanks for thies videos.... you are doing nice job

This is awesome! Thank you for discussing this! I was thinking the other day about those toys with colored oil that drops onto platforms, and I thought it would be really fun to build a large one that goes forever. A pump like this would be perfect, but I'll have to find immiscible fluids other than oils that can be pumped...if fact, if I could just pump the colored part and leave the clear fluid, it would be even better!

Thanks. Nice build.

This is very interesting. At my work we are actually trying to measure the reverse effect like you show in your video. We are interested in the voltage or current that is produced when a flow is introduced in the capillaries of a ceramic membrane. This is called streaming current or streaming potential. I never imagined the reverse was also true. Your video will help us a lot designing a system around this phenomenon!

That’s why you’re more accessible than Thunderf00t: no ranting, and you’re not so full of yourself. I really appreciated the explanation of how you built the apparatus, that really brought it down to earth.

Very interesting and thorough.

I remember back in the early 2000's, companies were selling (and still are) basement "waterproofing" systems for masonry walled foundation walls. I was and remain more than dubious for such a system in a retrofit on old work, but it likely would be quite effective on new construction. It all comes down to electrode installation and yes, the earth can be used as an electrode, but the efficiency goes even farther down. I discarded the notion for my old house, as our water issue was related to the fact that the back alley used to be a creek bed and the rears of many of our homes were literally part of the floodplain, so when it rained for extended periods, we'd start to get significant seepage of water through the concrete floor and masonry wall. I figured we'd need over 10 times the flow rate of such a device scaled up to handle it and that, plus impurities from the masonry and earth would, well, not be distilled water and chemically complicate the system by a great deal. Basically, it'd be a high electrolyte containing mixture that one's applying a high voltage to, which could turn into a double plus ungood thing in a confined space like a basement. Especially in a house that was so old that it had gas pipes (thankfully, capped off in the basement) running through the walls for old gas lights, as well as knob and tube wiring. On new work, it'd likely work well, although on new work, there'd have been a better path for water to flow provided that was away from the foundation walls and basements when the block was being constructed.

Very cool thanks Ben. Would be interesting to know how much the Sodium in the glass contributes to orientation of the neg end of the polar water molecule. I suspect a quartz frit filter with no Sodium would be rather expensive. Also since it's the field that's important, I wonder if the electrodes could be insulated thus eliminating any electrolysis effects. Just don't screw up and try and plug both pipette at the same time at 200V, I want to watch more videos. Craig

Love your work 👍

Amazing! Had no idea such a reaction takes place with water and glass 😮

Very interesting ! Awesome video !

Very nice explanation and very useful for my students in this pandemic times where there is no labs available and we as teacher need fo find attractive material for them!! Thanks for your effort to comunicate simply science!

Heyo! Love your channel; highly educational and well presented. I hope you don’t mind a request : I’ve always wanted to make a lighter than air magnetohydrodynamic blimp, but I’ve never had the time (and by time I mean talent.) I bet you could do it!

Great video, I wish you make a videoo on an devided cell for inorganic or organic chemical procesess.. it is a hard topic that many amateur chemists are banging and can not get through and it is becouse of the membrane, the type of it. You ve solved the problem in the traditional way (one can use just unglased porclain also, as ions can pass through it). Great video. My question is - what number Schott filter you use here??

Regarding the flow profile, I have noticed one similar to this. I put a 12" x 4ft PVC pipe on the front of a sealed 12" sub, and the airflow seemed to be focused towards the edge. Seemed to be particularly focused at 50Hz, which was the tubes' tuning. High frequency electrical signals may also show similar flow patterns.

Very informative Video 👍

wow... once again...what a concept that I have never thought of. an electrical field cutting through a magnetic field

Thanks for the video.

Fascinating, seems like this would have lots of applications in microfluidic devices.

Really nice construction :)
