I was gonna praise your humor sense... but then I saw your channels subs and realized you probably were serious... lmao What are you doing in a channel like this, bro?
Nice work, I would suggest using a pressure regulator valve if you were to redo the experiment so that if the hydrogen builds up to much within the fire extinguisher, it would be vented, preventing the extinguisher from going pop
Played around with HHO for a couple year's. I had best surface area production results with stainless steel wool. I never knew about urea. Thanks again......
@@GaryMcKinnonUFO Yes, this massively increased the hydrolysis efficiency. The palladium, induced a vibration on the water molecule which loosened its bonds. Man in Florida discovered this phenomenon.
pulse width modulation (PWM) circuitry, tune your cell to resonant frequency-gas is produced via capacitative discharge versus brute DC electrolysis. This type of gas is mono atomic H and O at highest entropy state (1L H2O/1800L gas). cell input is tuned to standing square wave modulation at high kilo-cycle frequencies. you will find harmonic 'sweet spots' where gas production is optimal at a fraction of the input wattage...so I have heard
your all right mate, really enjoy your way of getting stuff done. always head for my workshop to get active too after watching you rob, you have an honest intelligent ability and put me to shame. when all is said and done you make me an engineer, thanks teacher keep them coming.
Great video, another simple way is to use 2 balls of wire wool. Put one (+ )inside a nylon sock and sink it in the solution. Then put another (-) on top this doesn’t need to be socked but it won’t hurt. Then switch it on and watch the gas flow 🤪
Dear Rob, this devise is superb in conclusion with photo voltaic. If you run PV and not consuming all electric power you can produse hydrogen with this generator and store it for later purposes. (Called Power to gas, but many said it's not eficient enough - 30% effectivity only ...) For example feed a petrol motor with hydrogen you get electric power and hot water as well. Or just use the gas for heating or cooking. Great system! Thanks for the upload!
You cannot store Brown's gas. The oxidizer and the Hydrogen are never separate so the combustion mixture is always stoichiometric. That's why Brown's gas POPs really loudly, and Hydrogen merely whooshes. It would be suicidal to store brown's gas under any kind of pressure exceeding a balloon.
Prueba de poner entre ambas mallas de acero inoxidable una malla de plástico, y enrolla todo el conjunto, así logras un par de electrodos con gran área y pequeña separación. No necesitas Urea como electrolito, si la R de la celda es bien baja. Usa agua del grifo. Saludos de Américo Caorsi desde Tacuarembó - Uruguay, que siempre mira tus videos.
Very cool! I’ve been wondering about net positive electrolysis for donkey’s years and assumed it wasn’t possible because no one was talking about it! Thank you!
Water before separation is in the liquid phase, while water after recombination is in the vapour phase, which has lower internal energy due to the loss of hydrogen bonds, and a huge increase in entropy due to the extra space occupied. This is the apparent free energy.
Robert, a future video idea might be to put a cheap submersible pump in the electrolyzer. Hydrogen bubbles cling to the electrodes acting as an insulator reducing efficiency, vibrating the plates can free hydrogen and a pumped solution flowing over the plates from the bottom up could increase efficiency too. Eliminate the bubbles to increase efficiency and yield. Is there a best sonic or ultrasonic frequency for breaking the hydrogen bubbles free of the surface? How do you separate out the oxygen from the gas stream? A cheap plastic or glass tube open at both ends would work to do this, silicone it to the inside spacers and a rubber seal at the top to the lid and put the O2 collection tube lower in the gas column.
Upside down terracotta clay pot with the usual plumbing and spacers. These are porous and act as an "ion membrane" -- it is conductive when saturated with electrolyte.
Cheap&easy 5 gallon bucket high volume, a) coil 4ft x 12 inch stainless, drop in bucket, it spins open lining the inside, put ovc pipe between wraps for max flow. b) 2 inch vertical pipe in center stuffed with all thread and washers or stainless mesh so it doesn't protrude below pipe. Tap top center anode for hydrogen with 1/2 inch PVC, tap outer ring for oxygn (water) oxygen/chlorine (sea water) oxygen/nitrogen (urea) etc. Its also a self regulating rig, filling center pipe, lowering water level until gas feed line empties.

I try graphit coating on plate. As soon as you put electricity it is washing off right away. And i try to melt copper to liuquid phase and mix it whit graphite. It will not bond.
A few tips. AdBlue is a urea solution for motor vehicles. Urea is sold as a dry mix fertilizer under the market name Carbamide. It is also sold at health product stores as an additive to health spa bath water.

It is the most education and the most important education I think I've ever gotten in this life. And I think you good sir. Rock On & Prosper. Tesla would be proud
I got 10 years for electrolyzing baking soda water and cocain. I’ve struggled with clean energy. Jokes aside thanks for the informative video. We need this stuff out there more.
The Stainless Lathe is a great idea, cheap and easy to get hold of at most good builders merchants. To run a car you would just need to separate off the Hydrogen and store it, apparently, tanks with Lithium 6 Deuteride is best to absorb it, however getting this fairly harmless material can be a pain because it is used in nuclear bombs, however I did once hear of Carbon being made from Coconut shells and being used to absorb Methane in Tanks to run cars, maybe some sort of a carbon matrix would also work for Hydrogen to increase the storage capacity of tanks.
If you want to separate the hydrogen and oxygen, a good arrangement is some PVC pipes constructed in the basic shape of a "UU" with three uprights (If you imagine the center as one pipe). The Pipe on one side is the Cathode, the Pipe on the Other end is the Anode and the pipe in the center is for refilling. You can cap either end and store or vent as desired. Point of Safety for everyone. I have heard that stainless steel releases Chromates in this process and is not something you want laying around and you shouldn't just pour it down the sink.
@@incognitoalias2808 Stainless steel consists of part chromium. Chromium oxidizes to chromium oxides during electrolysis. One of those oxides is chromium oxide VI ( hexavalent ). HIGHLY CANCEROUS. In civilized countries, you can't by law ( and shouldn't regardless ) just dispose of that "rust". There is special protocol for disposing it(!). Don't breathe it in. Don't dump it outside/down the drain. Don't touch it with bare hands. Don't use stainless steel as a waste electrode. USE GRAPHITE RODS/PLATES. Best conductivity, best porousness, cheapest, most efficient. Breaks down into graphite powder/graphene.
@@CoincidenceTheorist No, they settle down as some kind of clay or so. Let it dry, scrap it into a bag and drop it of your local hazardous material disposal center.
I don't understand why those with the know how and inclination don't do what Stan himself said he did. Adjustable frequency alternating current electrolysis under vacuum between set gapped plates. Just like em waves can disassociate h2o he claimed the same at certain frequency ac and feed back resonance within the cell breaking the bonds on mass. Think opera singer and wine glass.
I made one of these out of two lengths of stainless steel cable for my old VW Beetle but didn't save much noticeably on fuel. Now you're talking urea as an electrolyte I might reinvestigate. Hmmm. Cheers 🍻 Ian, Birmingham
My guess is that you were not getting many amps. Surface area is immensely important, additionally a strongly conductive electrolyte helps a lot too. you should use KOH. Unless you have a lot of it, a stainless steel cable does not really have a lot of surface area. and you should never over drive it at 0.5 amps per sq inch of anode, or cathode. Build an electrolysis cell with 30 sq inches per electrode and drive it at 15 amps and you'll see reasonably good HHO production. or build a series of cells and make the electrolyte more conductive so that you can still drive it at 15 amps and you have reasonably good production while using less power. Because Hydrogen has a faster flame front, it helps burn more of the primary fuel during the power stroke which helps makes a low efficient engine more efficient. thus improving overall economy despite the power drawn for electrolysis.
@@kreynolds1123 There are a myriad of reasons that HHO injection is a counter productive waste of time. Just a few off the top of my head: There is no free lunch, all the energy to disassociate the water comes from the alternator which is in turn powered by the burning of fuel in the engine. Hydrogen is much less dense than air and actually displaces available oxygen, reducing not adding to power. The IC engine is at best 30% efficient meaning that at the absolute best it is only possible to recover 30% of the energy used in HHO production. On a practical level the volumes of HHO produced by most automotive applications is utterly insignificant in relation to the volume of gasses passing through the motor. The majority of the 'snake oil kits' produce less than 10 litres an hour on the other hand a 2 litre car engine operating at 2500RPM processes 300,000 litres an hour. If you want to produce more HHO you need to burn more fuel, there's no other way.
You don't have to pull power from the alternator. Most of the energy released in an engine is wasted as heat. This waste heat can be used to generate electricity using a Stirling engine or peltier module array... No extra strain on the engine...pure efficiency boost. Simple.
SURFACE AREA is the key to improved productivity and there is no better SURFACE ARE to VOLUME ration than inexpensive Extruded Carbon Water Filter Cartridges from your local hardware store, and using a very inexpensive brush-less DC water Pump to circulate the UREA through the Cartridges and back to a Recovery tank, where the Gases can be easily extracted and used for combustion or whatever else you desire. Obviously you use a Twin Filter Cartridge Housing so that both Carbon Filters act as Anode & Cathode and linked in the center via the common urea feed from the pump. The efficiency can be further improved by electroplating the Carbon Filters with very inexpensive NICKEL, which acts as a catalyst to the H2 production.
mustard mate...beautifully simple and effective...I have had a love/hate relationship with EML for the last 30 years, lol, thankfully this is SS and not galvanized pain.
An electrolyzer is not a Brown’s gas generator. A Brown’s gas generator is a type of electrolyzer. To make Brown’s gas requires a pulsed input. As electrolyzes go, yours is by far the simplest implementation I have seen. Thank you. I’d like to suggest you do the molar math to prove over unity. There are many claims of over unity electrolyzers, but I haven’t seen one that stands up to the math - meaning none are over unity.
Hi Rob, that was truly awesome, I’ve look at hydrogen generator over the year but as you so correctly say build one with all the plates and separators and gaskets and cleaning and on and on I never felt confident enough, your way is so simple I don’t know why I’ve not stumbled on it before, probably again like you say kept away from us, absolutely fantastic, thanks mate
I seen a vidya years ago of some bloke who had a computer controller and a sensor in the jar for the changing frequency of the water .so the computer would read the sensor and change the input sine wave to match this sweet spot he found . I cant find it .... oh and let's not forget Stanley Meyers from USA and also I'll add in Bob Lazar running his Corvette on Hydrogen
You should try using copper electrodes coated with your graphene ink, copper would normally deteriorate in an electrolytic cell like this but your waterproof ink might have quite interesting results
@@kreynolds1123 have you tried this? Or is that just a hypothesis? I'd think graphene would take higher temperatures or voltages to oxidize, and urea electrolysis doesn't produce oxygen it produces carbon dioxide and nitrogen aside from the hydrogen. But Idk cause I don't have any graphene to experiment with
I think a timed test to determine hydrogen volume produced & how much the assembly heats up at that voltage (wasted energy) should be in order. Getting too hot at higher voltages seems to be a common plague among diy electrolyzers.
Hello! I'm wondering if another route to go would be to use a stainless steel pressure cooker. You can use the cooker itself as one electrode. You can have the other electrode wired through the hole that will be created when you unscrew and remove the pressure gauge. Then you can connect a hose to the pressure release port where the 15 psi weight would usually sit.
FYI I was partnered with Dr..Alex Brown who disappeared on his way to start a 50:50 diesel /water carburetor at the major US diesel manufacturer in Wisconsin. The scarier fact is they did a 3-page feature story about the deal in Business Week and ty to find the story in a periodical search at a library anywhere...you will not find that week's magazine...it has been expunged world wide..
It would be nice to know the half cell reactions. The combined gas output looks like carbon dioxide, nitrogen and hydrogen. Is the overall reaction NH2CONH2 + H2O > N2 + 3H2 + CO2 ? (sorry about the lack of subscripts). Some papers suggest adding potassium hydroxide to convert the CO2 to a carbonate, keeping it in solution. They also suggest using nickel electrodes as this acts as a catalyst for greater gas production. I note, you do not attempt to collect the gasses evolved at the electrodes separately. This is not a problem for an OHH generator as the products are both reactive, but in this urea cell, the nitrogen and carbon dioxide are unwanted byproducts. Why is your cell brown, what is in solution? Any idea why urea electrolysis is not a more common method of hydrogen production, give how abundant urea is in the environment?
@@affiliatereviews4079 we make very poor use of the fertiliser contained sewage. This is often discharged to the rivers and sea unprocessed, it then poisons the environment, producing huge algae blooms. It would be far better if this was processed to produce fertiliser.
I built one of those in 2000 to run a lpg Landover it ended up been 2x 1.5m long and running 3 alts and 2 inverters to power it all. As long as you didnt have long hills you cld run it purely on water.
Loved this! If one had access to a lot of otherwise wasted animal livestock urine, the net energy gain might truly be positive. Run the electrical supply from solar pv and store the hydrogen for heating or transportation use.
One potential option using the stainless steel mesh to increase the output is to find a plastic mesh and roll that between the 2 electrode layers together. Or find a paint that is durable and insulating enough and paint. Another section of the stainless steel mesh to do the same thing.
Rob its a good idea to condition the stainless by running the device for an extended period ,then replacing the electrolyte , repeat a few times , you get a brown sludge as the ss 'rusts' , I got rather a high chrome reading from doing this ,so use gloves and dispose of sludge safely ,, can get 2 liters a minute for 10 amps 13.8 volts dc using potasium H , 7 plate series cell , plates about 200 cm square , stuff goes bang louder than a shot gun .Stan Meyers ran VW buggy with on board generated HHO , then got poisoned ! ,. suspect he figured something else out though,to do with nitrogen . His cells were SS tubes inside tubes ,cut to have same resonant frequency,completely immersed in water , probably set up to be a capacitor in an LC resonating circuit .

and thus in this way you get a mixture out of the pot.. not great for storing but there might be another great way to split that (other than separating the annode and kathode in separate but connected pots.
In actual fact you get H at negative electrode, H being Hydrogen. And you get O2 from the positive electrode. H =Hydrogen and o2=Oxygen,2 parts. Add both together and you get H2O which is water.
You can use the power from peltier thermoelectric generator, TEG, powered with waste heat to make the alternator take less power from the engine, that would reduce fuel consumption more, and it is a lot less complicated and less dangerous. Also it would make the battery last longer as lead acid batteries last longer if they are not discharged. It would not make a huge difference though, TEGs are not very efficient, and it is difficult to harvest waste heat very efficiently, but reducing the power the alternator draws would be much better use of what small amounts of electric energy you can get from TEGs in a car than taking the detour of hydrogen production.
@Mr Brightside The energy lost to breaking is typically few percent of the total energy used, compressed air does not do much for efficiency, it can increase power output, but with increased fuel consumption. Compressing a lot of air during a short time will mostly produce heat, very small part of the used energy will be stored as compressed air. Compressed air also has limited value in a car. All in all, that system would "pay", in form of gained efficiency, for it's own weight. Internal combustion engines in cars produces a lot more heat than usable energy. Granted, it is not easy to collect a very large part of that energy, and turn it in to electricity, but a TEG for a few dollars can produce a few watts as long as it is kept hot on one side, and "cool" on the other. They are not big, not heavy, not overly expensive, so you can use multiple TEGs, as long as you can cool the cool side properly.
@Mr Brightside No, airflow definitely helps in making it more efficient if air cooled, but is not needed. You are making assumptions based on the conclusion you want to reach, not on facts or logic reasoning. There are way better systems for regenerative breaking than compressed air ever can become. What you think when you obviously lack basic understanding of the problems, is completely irrelevant. How do you think you have realized significant value in the technique that is older than cars, that apparently no manufacturer realized since the invention of the car? Do you think you are god? Elon Musk? Leonardo da Vinci? Or even smarter than them?
@Mr Brightside Not aggressive, but frank, clear. Tell me that you know what you are talking about when it comes to compressed air as energy storage for regenerative braking, when your gathered knowledge about it. Your knowledge/experience with/about race cars might be impressive, that does not in any way mean that your wild guesses/feelings/assumptions about compressed air as energy storage has anything to do with reality. Some skills in one area is in no way automatically transferable to a divine understanding of a somewhat adjacent area. No. Just no, that's just not how reality works. You'd absolutely need divine powers to realize potential of that kind that that millions of intelligent and educated people, and all others, have completely missed over a period of more than a century.
Great video! I would use stainless steel bolts, washers, and nuts to attach the wires the electrodes. And use rubber grommets in the wire holes before sealing.
316L grade steel or your anode with corrode off quick.. its the only steel that can resist the Stripping action know for electroplating. (the + material will be stripped off to the - side
This does look a lot easier than messing about with SSteel pipes , which is what I used many years ago while doing this sort of thing, never knew about the Urea angle though.
Several people are commenting here that Rob is violating the 1st law of thermodynamics with his remarks in this video. At a closer look, this isn't really the case. I was confused for a second, too, but I assume it was only based on a misunderstanding or maybe not the best choice of words. What he didn't say is that he was only looking at the VOLTAGE he put in. In this sense it is correct, but it's not the complete picture. The discrepancy comes from the fact that not the entire chemically bound energy was considered in that equation. Urea electrolysis doesn't create real "Brown's Gas", i.e. no stoichiometric mixture of hydrogen and oxygen. There will be H2 produced at the cathode and N2 and CO2 at the anode. Urea will be consumed over time as kind of a 'fuel'. There's also some energy saved because to make it burn you would be required to take oxygen e.g. from atmospheric air, which is abundant and basically 'free'. All things considered, i.e. WITH the urea consumption and the external oxygen supply, the net energetic result is of course NOT positive. If anything is supposed to be 'free' here, it's only in the sense that oxygen is all around us and that urea is incredibly cheap. The laws of physics still apply. There's nothing free in a strict thermodynamical sense and when viewed as a closed system - and I'm 100% sure that Rob would agree to that. The thing is: we won't run out of oxygen or urea any time soon (the latter is literally in urine!), so you can consider the system as partially open. On a side-note: there is no such thing as a perfect electrode. The required voltage is always a little higher than the theoretical voltage according to the Nernst equation. This is also the case for the 0.37V that he mentioned. The exact amount of required "overvoltage" varies between electrode materials (graphite and iron are a bit at the lower end, but for many materials the electrolysis overvoltage is even beyond 1.0V!). For the complete equation, this overvoltage (and a bit of heat loss) must be taken into account and I have no doubts that Rob is aware of that.
Even better, electrolyze dilute glycerine solutions from bio-diesel effluent, dirt cheap stuff -- almost as cheap as crude oil these days lol, plus it is highly alkaline, making it strongly conductive. Ideally you'd want a PGM catalyst on the cathode and anode for best efficiency. Bonus, you won't even release CO2, but sequester it as carbonate in the process!
I plan on doing investigations into this next week... making a similar generator like the one above... powered by solar panels. Then take the brown gas into a burn chamber with a candle at the bottom, and have the gas (pop/pop/pop) as its being made in real time... just to see if its possible to make an efficient house heater for the winter... of course my tests will be outside in a safe environment until enough research/development can go into a very stable and safe mini furnace to contain the explosions.
There’s always something interesting to learn from this channel, I hope I can contribute but letting everyone know that there’s a product called “Add blue” (which is diesel exhaust fluid) that is mixed at almost the ratio stated in the video, 32.5% urea 67.5% water.
2 stainless steel balloon wisks stuffed with steel wool can be used as electrodes are easily put together at home, also you can collect both gasses at once to get Brown's gas(HHO,) or put a collection tube over each eletrode & you can collect the Hydrogen at the negative pull & Oxygen at the positive pull separately. Be careful Brown's gas is highly energetic don't mess with this or try it at home...not only will it result in water it will blow your hand clean off. I will leave out the basic home chemicals to make this possible. Funny how water & a few easily sourced materials can easily make a high explosive. Knowledge is power! They may be coming after our guns, but that is because they already robbed us of ou real weapons...basic understanding, common sense & the will not to be subjagated. The thing they fear most is the word "No"!
been thinking to do the balloon whisk, just got to find the right one. picked up stainless scrubbers, just need to find the right spill proof high heat plastic housing with some nice high heat plastic bottles or containers to put one or more whisks in. really want to mix this with methane if i can get that going but would love to look into powering a generator. what sorta uses can you use these for?
very cool rob. The biggest complaint I've seen on urea electrolysis is the foaming that occurs. I don't think 60 watts is a rate that can produce on demand gas production for jeweler torches (most active users of home built electrolysis) So it's probably way less of an issue. The other issue at low volume will be storing it safely. Flashback arrestor and bubbler to some sort of bladder?
Separate the oxygen and hydrogen by isolating the positive and negative sides. That way no oxygen mixes with the hydrogen. Much safer. Then transfer the hydrogen to a bladder or use a compressor.
Robert, in a past video you added capacitors with diodes and ran the generator off the caps. Would you be able to do the same thing here to have a consistent flow of energy to the hydrogen generator to run it off a cars 12 V system ? Thank you for being on UTube
From what I've seen in the past, is when the flame hits the metal, little water droplets form and trickle down around the flame. I have always wanted to try this myself.
i dabble a bit in hho too, however, i use battery acid on low amps high voltage LOTS of plates never heared of urea though KOH wants 1.8 to 2 volts and battery acid around 1.24. ppl say yes, but battery acid is dangerous, is acid... however they don't realise that all chemicals are, espacially when you think KOH is "safe" you need the salt/acid for the conductivity and not have it take part in the reaction. both KOH and H2SO4 work that way but since the break voltage with the acid is a lot lower, the output per wat is pretty high. also, its diluted down quite a bit compared to whats in the lead acid battery. just so far to get me the amps i need per cm2 to efficiently make my hho. for plates i use stainless sourcers that came very cheap with those plastic rim protectors 1mm inside 2mm outside that normally protects you for cuts . so i fot a stack of them with some 240 or so plates so it can connent to rectified mains voltage. since inverters for 12 VDC to 230VAC (pure sinus) are readily accessable in decent power output and the startup power doesn't need to be high since it just has to start, then the alternator can take over. but for testing, this is plenty. only add just enough H2SO4 so that the amps are good. no more no less the solution should be the current limiter. when set on 1700Watts i get around 12 liters HHO per minute so 4 liter of H2, thats a pretty decent amount i think. i use around 115 mA per cm2
I found on the net an easy way to store and pressurize the gas is to have two cylinders one fitting into the other fill the bottom one with water and have the gas inlet come from the top outside and go to the bottom center to fill the second cylinder putting weights on the second cylinder top controls the pressure.
The what you say It's an overunity reaction More energy out than put into the reaction Definition of ZPE over unity. Tapping a different dimension to extract energy that exists in the quantum foam It is always coming into and out of our diamention My favorite way to tap. Zero point energy Is when vapor bubbles formed in liquid say water. Forms under low pressure then they will collapse under higher pressure In doing so it realises that ape which is hotter than the son. At a nanospot It translates the whole periodic chart. I m always waking newer ways to tap into the zpe..
INTERESTING - And another great kitchen-top prototype !!! - - The 'urea' as a 'solution' (to the problem - might be taikung the pi$$ - pun),... well I hadn't considered that angle in the 'electrolysis' separation/dissassociation method,... water to gas mixture. (versus separated gases as an experiment ) . So I'm really interested in the COST BENEFITS,... and the H2+O flow rates per KW. !!??? - - As a rule of thumb, I've always used 15KW per cubic meter of Hydrogen, (at atmospheric pressure) - - And it would appear that your (speggetti jar ??) unit @ 21v x 3A would produce around 4ltrs of H2+O per hour,.... so that jar might need a 'incontinent drip' - UREA FLOW - (pun) ...into the jar, to keep it topped up. !!! . Can't wait to see your stats/results on flows & costs
Ooo thats cool!. Ive looked into HHO devices, but youre version is really do-able. I would consider drainage pipe and then i could attach a bubbler to it too. I assume drainage pipe is non reactive to chemicals. 100g Urea is about £5 on ebay. Thank you Rob, nice one :)
Serious question please. Here downunder 🇦🇺 where it’s hotter than hades and we get so much sunshine that it shines at night time 😉😜😜😂- everyone is installing solar power & selling surplus power into the grid during the day time when no one is home to utilise it. At night time when the sun has set & the family are all home from work / school & chew up copious power, for lights, cooking & infotainment, we buy that same power back from the grid at 4 times the electric Tarif we got for the power we put into the grid during the daytime when no one was home to utilise it. So the “answer” is Tesla “powerwall” lithium ion batteries to store your own power generated during the day time & draw down on it at night time rather than buy power from the grid at 4 times what you sold it for during the day when you had surplus. The “problem” being that the “Powerwall” li-ion batteries, cost ~$10k each and an average family home needs 2! It takes forever to see a return on that 20k investment. Is there any good reason that solar power during the day couldn’t electrolyse water into Hydrogen & Oxygen & store (compress) it into storage tanks on a household level, then at night time - re combine the DiHydrogenMonoxode back into water byproduct - to generate the power we need in our homes during darkness hours? Might not it be cheaper to be doing this every day than charging li-ion battery’s during the day & discharging them at night? It Tesla Powerwall battery charging / discharging MORE or LESS efficient than electrolysing urea solution, then re-combusting it to generate home power? To me it seems like a no brainer, to electrolyse water or urea solution and compress it into storage tanks during the day & use it again at night than charge / discharge Li-ion batteries? I’m guessing the engineers at Tesla are smart enough to have investigated this and passed it up for logical reasons (risk of hydrogen bomb explosions for starters).?

This type of gas is mono atomic H and O at highest entropy state (1L H2O/1800L gas). cell input is tuned to standing square wave modulation at high kilo-cycle frequencies. you will find harmonic 'sweet spots' where gas production is optimal at a fraction of the input wattage...so I have heard
your all right mate, really enjoy your way of getting stuff done. always head for my workshop to get active too after watching you rob, you have an honest intelligent ability and put me to shame. when all is said and done you make me an engineer, thanks teacher keep them coming.
Indication of liters (or fraction of liter) produced per minute would help to evaluate this very clever and simple assembly.

Great video, another simple way is to use 2 balls of wire wool. Put one (+ )inside a nylon sock and sink it in the solution. Then put another (-) on top this doesn’t need to be socked but it won’t hurt.
Then switch it on and watch the gas flow 🤪
Guess best press together the two steelwool lumps.
I just saw today that Mazda has a bunch of new technology in production with Brown's Gas! Hooray!
Dear Rob,
this devise is superb in conclusion with photo voltaic. If you run PV and not consuming all electric power you can produse hydrogen with this generator and store it for later purposes. (Called Power to gas, but many said it's not eficient enough - 30% effectivity only ...) For example feed a petrol motor with hydrogen you get electric power and hot water as well. Or just use the gas for heating or cooking.
Great system! Thanks for the upload!
You cannot store Brown's gas. The oxidizer and the Hydrogen are never separate so the combustion mixture is always stoichiometric. That's why Brown's gas POPs really loudly, and Hydrogen merely whooshes. It would be suicidal to store brown's gas under any kind of pressure exceeding a balloon.
@@aarondonaldson4164 what about storing it under water inside the balloon?

Very cool! I’ve been wondering about net positive electrolysis for donkey’s years and assumed it wasn’t possible because no one was talking about it! Thank you!
You get aught for naught, the urea takes energy to make :P
Water before separation is in the liquid phase, while water after recombination is in the vapour phase, which has lower internal energy due to the loss of hydrogen bonds, and a huge increase in entropy due to the extra space occupied. This is the apparent free energy.
You're never gonna get more energy out than in! That's just impossible.
@@martinbobak3009 That law is valid in closed systems not in open systems. Regards.
@@MrGoatflakes , urea can be replaced by urine ?.
Robert, a future video idea might be to put a cheap submersible pump in the electrolyzer. Hydrogen bubbles cling to the electrodes acting as an insulator reducing efficiency, vibrating the plates can free hydrogen and a pumped solution flowing over the plates from the bottom up could increase efficiency too. Eliminate the bubbles to increase efficiency and yield. Is there a best sonic or ultrasonic frequency for breaking the hydrogen bubbles free of the surface?
How do you separate out the oxygen from the gas stream? A cheap plastic or glass tube open at both ends would work to do this, silicone it to the inside spacers and a rubber seal at the top to the lid and put the O2 collection tube lower in the gas column.
Quick solution to that ultra sonic toothbrush maybe
Upside down terracotta clay pot with the usual plumbing and spacers. These are porous and act as an "ion membrane" -- it is conductive when saturated with electrolyte.
For the spacers, you can cut half-inch PVC pipe lengthwise and use 3" lengths of this.
Cheap&easy 5 gallon bucket high volume, a) coil 4ft x 12 inch stainless, drop in bucket, it spins open lining the inside, put ovc pipe between wraps for max flow. b) 2 inch vertical pipe in center stuffed with all thread and washers or stainless mesh so it doesn't protrude below pipe. Tap top center anode for hydrogen with 1/2 inch PVC, tap outer ring for oxygn (water) oxygen/chlorine (sea water) oxygen/nitrogen (urea) etc. Its also a self regulating rig, filling center pipe, lowering water level until gas feed line empties.

The Stainless Lathe is a great idea, cheap and easy to get hold of at most good builders merchants.
To run a car you would just need to separate off the Hydrogen and store it, apparently, tanks with Lithium 6 Deuteride is best to absorb it, however getting this fairly harmless material can be a pain because it is used in nuclear bombs, however I did once hear of Carbon being made from Coconut shells and being used to absorb Methane in Tanks to run cars, maybe some sort of a carbon matrix would also work for Hydrogen to increase the storage capacity of tanks.
another interesting idea mate - cheers
If you want to separate the hydrogen and oxygen, a good arrangement is some PVC pipes constructed in the basic shape of a "UU" with three uprights (If you imagine the center as one pipe). The Pipe on one side is the Cathode, the Pipe on the Other end is the Anode and the pipe in the center is for refilling. You can cap either end and store or vent as desired.
Point of Safety for everyone. I have heard that stainless steel releases Chromates in this process and is not something you want laying around and you shouldn't just pour it down the sink.
Do the chromates get released in the gas as well
This is why platinum plates are used for human consumption of the water and for nebulizing???
@@incognitoalias2808 Stainless steel consists of part chromium. Chromium oxidizes to chromium oxides during electrolysis. One of those oxides is chromium oxide VI ( hexavalent ).
HIGHLY CANCEROUS.
In civilized countries, you can't by law ( and shouldn't regardless ) just dispose of that "rust". There is special protocol for disposing it(!).
Don't breathe it in. Don't dump it outside/down the drain. Don't touch it with bare hands.
Don't use stainless steel as a waste electrode.
USE GRAPHITE RODS/PLATES. Best conductivity, best porousness, cheapest, most efficient. Breaks down into graphite powder/graphene.
@@CoincidenceTheorist No, they settle down as some kind of clay or so. Let it dry, scrap it into a bag and drop it of your local hazardous material disposal center.
I don't understand why those with the know how and inclination don't do what Stan himself said he did. Adjustable frequency alternating current electrolysis under vacuum between set gapped plates. Just like em waves can disassociate h2o he claimed the same at certain frequency ac and feed back resonance within the cell breaking the bonds on mass. Think opera singer and wine glass.
We call that mesh Ex Met' expanding metal. Get it from your builders merchant. Make sure to ask for stainless though!.
I made one of these out of two lengths of stainless steel cable for my old VW Beetle but didn't save much noticeably on fuel. Now you're talking urea as an electrolyte I might reinvestigate. Hmmm. Cheers 🍻

Basically pee.
Who would have think it! You just needed to carry more pee around with you.
My guess is that you were not getting many amps. Surface area is immensely important, additionally a strongly conductive electrolyte helps a lot too. you should use KOH. Unless you have a lot of it, a stainless steel cable does not really have a lot of surface area. and you should never over drive it at 0.5 amps per sq inch of anode, or cathode. Build an electrolysis cell with 30 sq inches per electrode and drive it at 15 amps and you'll see reasonably good HHO production. or build a series of cells and make the electrolyte more conductive so that you can still drive it at 15 amps and you have reasonably good production while using less power.
Because Hydrogen has a faster flame front, it helps burn more of the primary fuel during the power stroke which helps makes a low efficient engine more efficient. thus improving overall economy despite the power drawn for electrolysis.
@@kreynolds1123 There are a myriad of reasons that HHO injection is a counter productive waste of time. Just a few off the top of my head: There is no free lunch, all the energy to disassociate the water comes from the alternator which is in turn powered by the burning of fuel in the engine. Hydrogen is much less dense than air and actually displaces available oxygen, reducing not adding to power. The IC engine is at best 30% efficient meaning that at the absolute best it is only possible to recover 30% of the energy used in HHO production. On a practical level the volumes of HHO produced by most automotive applications is utterly insignificant in relation to the volume of gasses passing through the motor. The majority of the 'snake oil kits' produce less than 10 litres an hour on the other hand a 2 litre car engine operating at 2500RPM processes 300,000 litres an hour. If you want to produce more HHO you need to burn more fuel, there's no other way.
You don't have to pull power from the alternator. Most of the energy released in an engine is wasted as heat. This waste heat can be used to generate electricity using a Stirling engine or peltier module array... No extra strain on the engine...pure efficiency boost. Simple.
SURFACE AREA is the key to improved productivity and there is no better SURFACE ARE to VOLUME ration than inexpensive Extruded Carbon Water Filter Cartridges from your local hardware store, and using a very inexpensive brush-less DC water Pump to circulate the UREA through the Cartridges and back to a Recovery tank, where the Gases can be easily extracted and used for combustion or whatever else you desire. Obviously you use a Twin Filter Cartridge Housing so that both Carbon Filters act as Anode & Cathode and linked in the center via the common urea feed from the pump.
The efficiency can be further improved by electroplating the Carbon Filters with very inexpensive NICKEL, which acts as a catalyst to the H2 production.
delawarecop What type of carbon filter do you mean?

An electrolyzer is not a Brown’s gas generator. A Brown’s gas generator is a type of electrolyzer. To make Brown’s gas requires a pulsed input. As electrolyzes go, yours is by far the simplest implementation I have seen. Thank you. I’d like to suggest you do the molar math to prove over unity. There are many claims of over unity electrolyzers, but I haven’t seen one that stands up to the math - meaning none are over unity.

Besides urea you could use distilled water and potassium chloride as a catalyst.

cheers mate - have fun!
What kind of urea is it? I'm new to this and I don't want to get the wrong brand/kind.
You should try using copper electrodes coated with your graphene ink, copper would normally deteriorate in an electrolytic cell like this but your waterproof ink might have quite interesting results
the carbon would oxidize to graphene oxide, lose conductivity and stop working.
@@kreynolds1123 have you tried this? Or is that just a hypothesis? I'd think graphene would take higher temperatures or voltages to oxidize, and urea electrolysis doesn't produce oxygen it produces carbon dioxide and nitrogen aside from the hydrogen. But Idk cause I don't have any graphene to experiment with
I think a timed test to determine hydrogen volume produced & how much the assembly heats up at that voltage (wasted energy) should be in order.
Getting too hot at higher voltages seems to be a common plague among diy electrolyzers.
Hello! I'm wondering if another route to go would be to use a stainless steel pressure cooker. You can use the cooker itself as one electrode. You can have the other electrode wired through the hole that will be created when you unscrew and remove the pressure gauge. Then you can connect a hose to the pressure release port where the 15 psi weight would usually sit.
That would work except even stainless whatever you use will eventually be consumed by the electrolosis.
@@magicone9327 Only the positive electrode gets consumed. As long as the pressure cooker was the negative electrode, it would not get consumed.

Skirting around the issue of why the water isn't clear. :-) Taking the p**s, lol.
It would be nice to know the half cell reactions. The combined gas output looks like carbon dioxide, nitrogen and hydrogen.
Is the overall reaction NH2CONH2 + H2O > N2 + 3H2 + CO2 ? (sorry about the lack of subscripts).
Some papers suggest adding potassium hydroxide to convert the CO2 to a carbonate, keeping it in solution. They also suggest using nickel electrodes as this acts as a catalyst for greater gas production. I note, you do not attempt to collect the gasses evolved at the electrodes separately. This is not a problem for an OHH generator as the products are both reactive, but in this urea cell, the nitrogen and carbon dioxide are unwanted byproducts. Why is your cell brown, what is in solution?
Any idea why urea electrolysis is not a more common method of hydrogen production, give how abundant urea is in the environment?
Urea is used in fertilizer. To use it as a fuel would directly compete with farmers and raise the cost of food. Also it is made from natural gas.
@@affiliatereviews4079 we make very poor use of the fertiliser contained sewage. This is often discharged to the rivers and sea unprocessed, it then poisons the environment, producing huge algae blooms. It would be far better if this was processed to produce fertiliser.

Loved this! If one had access to a lot of otherwise wasted animal livestock urine, the net energy gain might truly be positive. Run the electrical supply from solar pv and store the hydrogen for heating or transportation use.
One potential option using the stainless steel mesh to increase the output is to find a plastic mesh and roll that between the 2 electrode layers together. Or find a paint that is durable and insulating enough and paint. Another section of the stainless steel mesh to do the same thing.
Rob its a good idea to condition the stainless by running the device for an extended period ,then replacing the electrolyte , repeat a few times , you get a brown sludge as the ss 'rusts' , I got rather a high chrome reading from doing this ,so use gloves and dispose of sludge safely ,, can get 2 liters a minute for 10 amps 13.8 volts dc using potasium H , 7 plate series cell , plates about 200 cm square , stuff goes bang louder than a shot gun .Stan Meyers ran VW buggy with on board generated HHO , then got poisoned ! ,. suspect he figured something else out though,to do with nitrogen . His cells were SS tubes inside tubes ,cut to have same resonant frequency,completely immersed in water , probably set up to be a capacitor in an LC resonating circuit .

I believe S Myers also used a FWM. I wonder if changing the hz or using high voltage can help break the bond easier
Hmm, what is the resonant frequency of a water molecule?
@@MarkSeve on german wikipedia is written that its lowest resonance is 22,23508 GHz. But multiples of it too. But the implication that full divisions(/1x) wont work is untrue since i found that at ~22khz there is a slight increase.

So just divide 22,23508 GHz by 10/100/1000/10k/100k/1mio
I didn't compare 22khz vs 222khz or megahertz since i didn't have the right oscillator at the moment. (You need an oscillator an a mosfet which can handle the frequency you want to use.

After a bit of googling, you'll get H2 at one electrode and CO2 and N2 at the other. Browns gas is actually o2 and H2
Electrolysis in general or using urea specifically?
Yeah diatomic hydrogen and oxygen not separated but together is browns gas from what I understand.
and thus in this way you get a mixture out of the pot.. not great for storing but there might be another great way to split that (other than separating the annode and kathode in separate but connected pots.
In actual fact you get H at negative electrode, H being Hydrogen. And you get O2 from the positive electrode. H =Hydrogen and o2=Oxygen,2 parts. Add both together and you get H2O which is water.
@@roberttill3787 its actually 2 hydrogen and 1 oxygen

From russia... try to set pelter termo generator on car exhsust, to get electricity for hho electroliser ))) sorry for bad english ))
You can use the power from peltier thermoelectric generator, TEG, powered with waste heat to make the alternator take less power from the engine, that would reduce fuel consumption more, and it is a lot less complicated and less dangerous. Also it would make the battery last longer as lead acid batteries last longer if they are not discharged.
It would not make a huge difference though, TEGs are not very efficient, and it is difficult to harvest waste heat very efficiently, but reducing the power the alternator draws would be much better use of what small amounts of electric energy you can get from TEGs in a car than taking the detour of hydrogen production.
@Mr Brightside The energy lost to breaking is typically few percent of the total energy used, compressed air does not do much for efficiency, it can increase power output, but with increased fuel consumption. Compressing a lot of air during a short time will mostly produce heat, very small part of the used energy will be stored as compressed air. Compressed air also has limited value in a car. All in all, that system would "pay", in form of gained efficiency, for it's own weight.
Internal combustion engines in cars produces a lot more heat than usable energy. Granted, it is not easy to collect a very large part of that energy, and turn it in to electricity, but a TEG for a few dollars can produce a few watts as long as it is kept hot on one side, and "cool" on the other. They are not big, not heavy, not overly expensive, so you can use multiple TEGs, as long as you can cool the cool side properly.
@Mr Brightside No, airflow definitely helps in making it more efficient if air cooled, but is not needed. You are making assumptions based on the conclusion you want to reach, not on facts or logic reasoning.
There are way better systems for regenerative breaking than compressed air ever can become. What you think when you obviously lack basic understanding of the problems, is completely irrelevant.
How do you think you have realized significant value in the technique that is older than cars, that apparently no manufacturer realized since the invention of the car? Do you think you are god? Elon Musk? Leonardo da Vinci? Or even smarter than them?
@Mr Brightside Not aggressive, but frank, clear. Tell me that you know what you are talking about when it comes to compressed air as energy storage for regenerative braking, when your gathered knowledge about it. Your knowledge/experience with/about race cars might be impressive, that does not in any way mean that your wild guesses/feelings/assumptions about compressed air as energy storage has anything to do with reality. Some skills in one area is in no way automatically transferable to a divine understanding of a somewhat adjacent area. No. Just no, that's just not how reality works. You'd absolutely need divine powers to realize potential of that kind that that millions of intelligent and educated people, and all others, have completely missed over a period of more than a century.
What is this ? Thanks .
Great video! I would use stainless steel bolts, washers, and nuts to attach the wires the electrodes. And use rubber grommets in the wire holes before sealing.
Open out a stainless steel scourer (like a brillo pad) and it will do the job much cheaper.
316L grade steel or your anode with corrode off quick.. its the only steel that can resist the Stripping action know for electroplating. (the + material will be stripped off to the - side
This does look a lot easier than messing about with SSteel pipes , which is what I used many years ago while doing this sort of thing, never knew about the Urea angle though.
Several people are commenting here that Rob is violating the 1st law of thermodynamics with his remarks in this video. At a closer look, this isn't really the case. I was confused for a second, too, but I assume it was only based on a misunderstanding or maybe not the best choice of words. What he didn't say is that he was only looking at the VOLTAGE he put in. In this sense it is correct, but it's not the complete picture. The discrepancy comes from the fact that not the entire chemically bound energy was considered in that equation. Urea electrolysis doesn't create real "Brown's Gas", i.e. no stoichiometric mixture of hydrogen and oxygen. There will be H2 produced at the cathode and N2 and CO2 at the anode. Urea will be consumed over time as kind of a 'fuel'. There's also some energy saved because to make it burn you would be required to take oxygen e.g. from atmospheric air, which is abundant and basically 'free'. All things considered, i.e. WITH the urea consumption and the external oxygen supply, the net energetic result is of course NOT positive. If anything is supposed to be 'free' here, it's only in the sense that oxygen is all around us and that urea is incredibly cheap. The laws of physics still apply. There's nothing free in a strict thermodynamical sense and when viewed as a closed system - and I'm 100% sure that Rob would agree to that. The thing is: we won't run out of oxygen or urea any time soon (the latter is literally in urine!), so you can consider the system as partially open.
On a side-note: there is no such thing as a perfect electrode. The required voltage is always a little higher than the theoretical voltage according to the Nernst equation. This is also the case for the 0.37V that he mentioned. The exact amount of required "overvoltage" varies between electrode materials (graphite and iron are a bit at the lower end, but for many materials the electrolysis overvoltage is even beyond 1.0V!). For the complete equation, this overvoltage (and a bit of heat loss) must be taken into account and I have no doubts that Rob is aware of that.
Even better, electrolyze dilute glycerine solutions from bio-diesel effluent, dirt cheap stuff -- almost as cheap as crude oil these days lol, plus it is highly alkaline, making it strongly conductive. Ideally you'd want a PGM catalyst on the cathode and anode for best efficiency. Bonus, you won't even release CO2, but sequester it as carbonate in the process!
Thank you! I am planning to make a Brown's gas generator. I know nothing about how to make these, but I am going to do it.
I plan on doing investigations into this next week... making a similar generator like the one above... powered by solar panels. Then take the brown gas into a burn chamber with a candle at the bottom, and have the gas (pop/pop/pop) as its being made in real time... just to see if its possible to make an efficient house heater for the winter... of course my tests will be outside in a safe environment until enough research/development can go into a very stable and safe mini furnace to contain the explosions.
Key in the chuck is killin me man.
Have you played with the frequency? tuning to a resonance for the liquid may just split the molecules more efficiently.
There’s always something interesting to learn from this channel, I hope I can contribute but letting everyone know that there’s a product called “Add blue” (which is diesel exhaust fluid) that is mixed at almost the ratio stated in the video, 32.5% urea 67.5% water.

Yes Sir.. Wal-Mart sells it.i used to use it in my diesel Sprinter van
1-2v at high amps works best. also high freq pulsed DC also does well
2 stainless steel balloon wisks stuffed with steel wool can be used as electrodes are easily put together at home, also you can collect both gasses at once to get Brown's gas(HHO,) or put a collection tube over each eletrode & you can collect the Hydrogen at the negative pull & Oxygen at the positive pull separately. Be careful Brown's gas is highly energetic don't mess with this or try it at home...not only will it result in water it will blow your hand clean off. I will leave out the basic home chemicals to make this possible. Funny how water & a few easily sourced materials can easily make a high explosive.
Knowledge is power! They may be coming after our guns, but that is because they already robbed us of ou real weapons...basic understanding, common sense & the will not to be subjagated. The thing they fear most is the word "No"!

Baking soda... hydrogen sulfide... potato juice... any catalyst, really..
very cool rob. The biggest complaint I've seen on urea electrolysis is the foaming that occurs. I don't think 60 watts is a rate that can produce on demand gas production for jeweler torches (most active users of home built electrolysis) So it's probably way less of an issue. The other issue at low volume will be storing it safely. Flashback arrestor and bubbler to some sort of bladder?
Separate the oxygen and hydrogen by isolating the positive and negative sides. That way no oxygen mixes with the hydrogen. Much safer. Then transfer the hydrogen to a bladder or use a compressor.
Robert, in a past video you added capacitors with diodes and ran the generator off the caps. Would you be able to do the same thing here to have a consistent flow of energy to the hydrogen generator to run it off a cars 12 V system ? Thank you for being on UTube

never heared of urea though
KOH wants 1.8 to 2 volts and battery acid around 1.24.
ppl say yes, but battery acid is dangerous, is acid... however they don't realise that all chemicals are, espacially when you think KOH is "safe"
you need the salt/acid for the conductivity and not have it take part in the reaction. both KOH and H2SO4 work that way but since the break voltage with the acid is a lot lower, the output per wat is pretty high.
also, its diluted down quite a bit compared to whats in the lead acid battery. just so far to get me the amps i need per cm2 to efficiently make my hho.
for plates i use stainless sourcers that came very cheap with those plastic rim protectors 1mm inside 2mm outside that normally protects you for cuts .
so i fot a stack of them with some 240 or so plates so it can connent to rectified mains voltage.
since inverters for 12 VDC to 230VAC (pure sinus) are readily accessable in decent power output and the startup power doesn't need to be high since it just has to start, then the alternator can take over. but for testing, this is plenty.
only add just enough H2SO4 so that the amps are good. no more no less the solution should be the current limiter.
when set on 1700Watts i get around 12 liters HHO per minute so 4 liter of H2, thats a pretty decent amount i think.
i use around 115 mA per cm2
I found on the net an easy way to store and pressurize the gas is to have two cylinders one fitting into the other fill the bottom one with water and have the gas inlet come from the top outside and go to the bottom center to fill the second cylinder putting weights on the second cylinder top controls the pressure.
My favorite UA-cam channel
The what you say
It's an overunity reaction
More energy out than put into the reaction
Definition of ZPE over unity.
Tapping a different dimension to extract energy that exists in the quantum foam
It is always coming into and out of our diamention
My favorite way to tap. Zero point energy
Is when vapor bubbles formed in liquid say water. Forms under low pressure then they will collapse under higher pressure
In doing so it realises that ape which is hotter than the son. At a nanospot
It translates the whole periodic chart.
I m always waking newer ways to tap into the zpe..
I love this video. Can you suggest a safe and easy to make hydrogen storage method?
INTERESTING - And another great kitchen-top prototype !!!
- - The 'urea' as a 'solution' (to the problem - might be taikung the pi$$ - pun),... well I hadn't considered that angle in the 'electrolysis' separation/dissassociation method,... water to gas mixture. (versus separated gases as an experiment )
.
So I'm really interested in the COST BENEFITS,... and the H2+O flow rates per KW. !!???
- - As a rule of thumb, I've always used 15KW per cubic meter of Hydrogen, (at atmospheric pressure) - - And it would appear that your (speggetti jar ??) unit @ 21v x 3A would produce around 4ltrs of H2+O per hour,.... so that jar might need a 'incontinent drip' - UREA FLOW - (pun) ...into the jar, to keep it topped up. !!!
.
Can't wait to see your stats/results on flows & costs
How would you use the hydrogen,what type of container to store this stuff?
Ive ran electrolysis off of small solar panels using other solutions. The efficiency of urea solution sounds impressive.
it's pretty cool stuff mate - well worth looking into
Ooo thats cool!. Ive looked into HHO devices, but youre version is really do-able. I would consider drainage pipe and then i could attach a bubbler to it too. I assume drainage pipe is non reactive to chemicals. 100g Urea is about £5 on ebay. Thank you Rob, nice one :)
glad you liked it mate
Just use diesel exhaust fluid (DEF). It's a high-purity urea solution in water.
Very informative. Something I will need to use sometime as I am off grid and in the bush.
Cars in the future will be piss powered!
@Stimpy&Ren Doesn't matter, worth trying. We call that doing science.
Robert looks like a young Bill Owen from last of the summer wine.
first for that one mate - I usually get compared to Anthony Hopkins
Serious question please.
Here downunder 🇦🇺 where it’s hotter than hades and we get so much sunshine that it shines at night time 😉😜😜😂- everyone is installing solar power & selling surplus power into the grid during the day time when no one is home to utilise it.
At night time when the sun has set & the family are all home from work / school & chew up copious power, for lights, cooking & infotainment, we buy that same power back from the grid at 4 times the electric Tarif we got for the power we put into the grid during the daytime when no one was home to utilise it.
So the “answer” is Tesla “powerwall” lithium ion batteries to store your own power generated during the day time & draw down on it at night time rather than buy power from the grid at 4 times what you sold it for during the day when you had surplus.
The “problem” being that the “Powerwall” li-ion batteries, cost ~$10k each and an average family home needs 2!
It takes forever to see a return on that 20k investment.
Is there any good reason that solar power during the day couldn’t electrolyse water into Hydrogen & Oxygen & store (compress) it into storage tanks on a household level, then at night time - re combine the DiHydrogenMonoxode back into water byproduct - to generate the power we need in our homes during darkness hours?
Might not it be cheaper to be doing this every day than charging li-ion battery’s during the day & discharging them at night?
It Tesla Powerwall battery charging / discharging MORE or LESS efficient than electrolysing urea solution, then re-combusting it to generate home power?
To me it seems like a no brainer, to electrolyse water or urea solution and compress it into storage tanks during the day & use it again at night than charge / discharge Li-ion batteries?
I’m guessing the engineers at Tesla are smart enough to have investigated this and passed it up for logical reasons (risk of hydrogen bomb explosions for starters).?
Sir, you did a great job. God bless you
