      130 kms x2 in 1:1 ratio of rpm 😎
      Meaning Tesla range have to be over 13,000 kms in single charge in 1:1 rpm and 24,000 kms and above in single charge with a transmission system with 1:13 rpm ratio mean 1 rpm of motor 13 rpm of wheels in middle level 1:1 in Torque mode 13:1 mean motor 13 rpm wheels 1 😇
      Elon musk cars have over 500 to 600 miles range 😏
      Change rpm to 1:1 can give us over 9x higher range which is over 4500 to 5400 miles per charge and I m not talking about using and transmission system which easily boosts the range of any Tesla cars over 13,000 to 24,000 miles in single charge 😏

      the explosive factor is a myth bred by images of things like the Hindenburg disaster ( which wasn't caused by the hydrogen likely, the airframe was coated w butylene dope that is extremely flammable. hydrogen gas is less explosive than gasoline vapor yet we drive around with a gas tank that has gasoline vapor in it.
      I saw an episode of the PBS Nova program in the late 70s on hydrogen ( kind of depressing 40 yrs later it is still TBD). They had a partially full can of gasoline which meant gas vapor was in the rest and a gas can full of hydrogen. they fired a tracer round into the two cans. the gas can exploded like dynamite going off, the hydrogen can simply burned a flame out the hole.

    Keep in mind that green H2 is essentially free...IF it is made from Renewables (wind/solar) that can't otherwise use it. During peak sun (or wind) the grid might not be able to use all of it...hence the benefits of storage (batteries,pumped hydro, etc). If the grid can't use it and storage is already "full", the surplus can be dumped to H2 production---thus "free" H2.
    Overbuilding off-shore wind (and rooftop solar) is the best way to get off fossil fuels--all the excess can be stored as a buffer or used for H2 production.

    • @nolan4339
      @nolan4339 2 года назад

      While it is the standard thought that renewable surpluses on the grid can power hydrogen synthesis, that model is not really that realistic. The reason I say that is because grid operators never want a steady surplus of intermittent power on the grid, and so will likely only want to build out renewables to the point where there are small periodic spikes that go beyond demand, with stored energy sources, like fuels to make up for the pitfalls, Also, the companies that will build the electrolyzers to produce the hydrogen will not want the responsibility of regulating the power surplus on the network or to be a competitor for it among load-leveling battery banks, or other applications thus never having an assured supply of energy.
      I think it is more likely that hydrogen synthesis facilities would build their own dedicated renewable micro-grids, with limited grid connections so that they can accurately predict the amounts of energy they need to handle, and thus the amount of infrastructure that they need.

      Regarding your specific statements, IN FACT, grid operators ALWAYS want a steady surplus of power on the grid. That is kind of the "problem." Because it is a surplus, however, it must be wasted, which is the "answer." A couple of years ago, Texas was doing this with up to 15% of its wind power. Utilities will do anything that makes a profit and stabilizes the grid, period. Selling something they can't use is a no-brainer. Hydrogen generation can do that. Similarly, electrolyzer companies will want to make a profit, and would welcome cheap electricity, and electricity that is already being curtailed can be as cheap as free.
      You might think it is likely that electrolyzers will build their own grids. I know of one huge site that did that. But why do that when a free resource is being wasted?
      I am not sure why you are biased against the interests of utilities, hydrogen producers, researchers, but it is perfectly fine. They will not be deterred.

      @nolan4339 2 года назад +1

      @@bradwinfast1236 yes, when there are renewable surpluses, selling this extra power for cheap will happen, but if you get multiple parties competing for this capacity, then it will no longer be so cheap, and power companies will not want to sell it for cheap because it represents over built production capacity, which needs to be paid for. So the amount of this cheap surplus will be limited.
      Relying on Green Hydrogen production will need extremely cheap power, and a huge amount of it in order to fulfill societies hydrogen demand, and while some of this power will likely come from grid surpluses, I think it will be cheaper and more reliable to build renewable power facilities that are directly paired with electrolyzer plants, for the majority of this production, rather than trying to funnel these huge power loads through the grid.

      @NotMyActualName_ 2 года назад

      Use as energy storage is really hydrogen's only possible niche it could fill. It's not useful as a transportation fuel because it's too low density. It's not useful for full scale production, because if you need green energy systems like solar and wind to power your hydrogen electrolysis, you might as well just use them to power the grid directly and not waste a step.
      But for storage, it's an OK option if the efficiency to produce is high. Currently I think water pumping and gravitational storage require a LOT less complex technology and even though they have their own losses, the simplicity of building them is in their favor. No technological challenges to overcome, just engineering and design.

    I did research into the hydrogen market about a month prior to the video and based on what I was able to read from published articles on Google, I feel like the information used is old and/or out of date. In particular I am up in arms about the types of production, color variety of hydrogen, and the cost to produce it. I found that there were about 5-6 colors, $2-8 per kilogram depending on the color, and a myriad of ways to produce hydrogen in each of those color categories. Most of which were economically unviable. I think it's important to note that the vast majority of hydrogen is purchased by the oil & gas sector, which further hinders future hydrogen production methods from being produced as it creates a volume of production barrier for new producers on the market. Most new producers will be relegated to serve very niche markets until they can scale production quantity to oil & gas levels.
    While the information was valuable in this video, the depth and scope I felt was misleading. And I should clarify that I am BY FAR not an expert. These assertions are all from articles found from about 1.5 hours of research on the subject.

    I thought of something while watching this. You said something about the industry not wasting even a single drop of hydrogen. Somehow, We are supposed to believe that the energy sector will do everything they can to reduce the amount of hydrogen they lose....But TODAY, we don't even come close to doing that with water or natural gas. Natural gas is leaking all over the place, which is not only bad for climate change, but raises costs...and water...ohhh boy, the amount of water that we lose through all these old pipes that we won't replace is insane. So we are expected to believe that they will collect and contain the hydrogen, which by the way, has the ability to seep THROUGH metal ( causing the metal to become brittle ) because it's so small, but we can't stop water from leaking literally everywhere, when water is able to be contained infinitely easier than not just a gas, but the lightest gas, made of the smallest element.
    And at the end, you said "we need a variety of clean energy sources for a cleaner future". Please don't call Hydrogen ( or batteries ) an energy source. They are an Energy Carrier. They are not a source of energy. They are storage mediums. They don't "produce" anything...at all...what-so-ever.

      Actually, for such short-time-storage are batteries much better and cheaper. Hydrogen becomes attractive when you have days or weeks of excess energy (or shortage). Simply spoken: The costs of battery storage mainly depend on the kWh (storage capacity), the costs of hydrogen energy storage depend mainly on kW (storage power, energy transformation, electrolyser, fuel cells,...).
      However, in small units (detached houses), efficiency of hydrogen storage isn't THAT bad because you can utilize waste heat for hot water/heating at least.

      Hydrogen seems like the ultimate replacement for petrol in cars.
      It is better than batteries in energy-density.
      Except for the need for pressurised and cooled fueling and storage.
      And the need to revise all of the systems.
      Ultimately there would have to be a national hydrogen grid like there is for natural gas.
      Which are also extreme costs.
      But batteries can't beat hydrogen in terms of energy-densiity for cars.
      Maybe with solid state batteries they'll come close defeating the purpose of hydrogen. Unless hydrogen engines are way cheaper and easier to build than full electrics and their batteries.
      It depends on a lot.
      Hydrogen's biggest advantages are energy-density and the benign elements it breaks down into.
      So it will have uses in these niche categories. But if solid state batteries are affordable and realistic to produce and rival hydrogen then I don't think hydrogen could replace batteries as the energy storage medium "of the future".
      We'll probably have a mix of both.
      You may dream of producing hydrogen from your own solar and driving your car with it but ultimately you probably still need very special, expensive elements and tools, products to make use of these technologies.
      Which may be as much or even worse than batteries.
      Batteries are less volatile than pressurized hydrogen.

    I’m sure there will always be a use for hydrogen as a fuel source, and I’m sure use cases will grow. But as others have probably pointed out, the fact that you have to take perfectly storable green energy and create hydrogen means, according to laws of energy conservation, that you will always be less efficient than just making green electricity and storing in batteries. And since battery materials are in the realm of recycle-able there is literally no reason to use hydrogen. Not only is it inefficient when compared to just storing electricity directly in batteries, but it also needs an entire infrastructure build to transport it to fueling stations. And transporting via trucks itself is fuel consuming. Electricity already has the delivery infrastructure built. Its just the wires that already exist. Plus as electric cars become common, apartment complexes will inevitably have a charging station in your parking space. So its also just more user convenient. So really Matt, I think you can be decided on this one :P

    The production of hydrogen via electrolysis can be made more efficient by adding a magnet. This is what researchers from the Institut Català d'Investigació Química in Spain write in Nature Energy.
    They showed that the presence of an external magnetic field of less than 450 mT stimulates the production of the electrocatalytic activity at the anode, thereby improving the production of hydrogen in ionized (alkaline) water.
    The magnetic field affects the magnetic (spin) orientation of the catalyst which in turn directs the orientation of the oxygen atoms during the reaction all in the same direction. This makes the reaction more efficient. The ferrite catalyst NiZnFe4Ox in combination with a magnet yielded the greatest improvement.

    I would point out that hydrogen does not absolutely require an infrastructure that matches or corresponds to the existing one for gasoline and diesel. It is not necessary to haul H2 in trucks. We can produce H2 locally as needed, using the best production method for the immediate market, with supplemental storage if required. This approach actually improves the efficiency of energy delivery, because energy need not be consumed by transporting fuel on roads. Because H2 is so different from petroleum fuels, we should be careful not to make assumptions about it from a petroleum-based viewpoint.

    Hi Matt, hysata looks promising but if their efficiency is 40.4 kWh/kg H2 they are only on par with high temp electrolysis that takes in steam as an input. Alkaline and PEM are in and around 47-52 kWh/kg. Alkaline and PEM are both considered low temp electrolyzers.

      @mike160543 2 года назад

      Ammonia produced using renewable electricity can directly replace ammonia made using carbon compounds. Ammonia is being widely advocated as a green, carbon free fuel. The incentive lies in the fact that ammonia can be made from electrolytic hydrogen and atmospheric nitrogen. Topsoe among others have developed ammonia technology that is capable of intermittent operation and does not require an air separation plant. Technology for storing and transporting liquid ammonia at atmospheric pressure and at -33oC is well established.1 cubic metre of liquid ammonia weighs 690 Kg of which 121,76 Kg is hydrogen. Hydrogen has to be cooled to - 253oC before it liquefies, and then 1 cubic metre weighs 70,85 Kg. So liquid ammonia contains 1.72 times as much hydrogen as does liquid hydrogen! Ammonia can be kept liquid with a conventional refrigeration unit, while hydrogen requires compression and expansion of the gas through a turbine. Liquefying hydrogen can use up to 30% of the energy content of the feed hydrogen. Ammonia is produced as a liquid.

    @saumyacow4435 2 года назад

    The biggest problem with catalysers was cost, not efficiency. Whether this new tech has cost advantages - that's the question. Also the really big problem with hydrogen is storage. Do you a) spend a large fraction of the available energy liquefying hydrogen, or b) expend a large (though not as large) fraction of the energy on compression, plus the sheer scale/cost of high pressure storage. What I'd love to see is more refinement of the liquefying process - recovering or storing the heat energy usually lost in this process.
    Oh and one other thing. Cost is more important than efficiency. Even if liquid hydrogen loses half the energy you put in, that doesn't matter if the energy you put in is cheap. Hence, hydrogen production being integrated with solar/wind farms. What this means is a larger solar/wind farm and a variable hydrogen production rate - using only the energy not shipped as electricity.

    Interesting, and matches up to why Stanley Myers (sp) and his hydrogen powered car used a pulsed circuit to drive his electrolyizers. Having a sponge like substance allows a circuit to remain connected, keeping resistance and capacitance stable, unlike bare plate to plate and the bubbing problem, the gas release between the plates causes higher resistance and capacitance trying to complete the circuit through the bubble. Stanley did it with pulses, allowing the bubbles to collapse and keep resistance and capacitance stable.

  • @rashkavar

    I find it questionable to call hydrogen a renewable energy source - unless you can either find a naturally occurring source of hydrogen gas such as the science fiction concept of a ram scoop to fuel a spacecraft or you figure out a H-H fusion reaction that produces a net gain in power including the energy cost of separating out the proper isotopes and isolating the hydrogen (refining heavy water and electrolysing it for the Deuterium+Deuterium reaction, for instance), it's not generating power. It's storing it.
    Hydrogen Fuel Cells are functionally comparable to a lithium ion battery - a portable means of transporting energy that was previously generated by large grid-power installations.
    Which runs into a problem. Hydrogen is an extremely reactive gas. Anything that uses hydrogen storage tanks and fuel cells needs to be *extremely* careful to avoid sparks, because the explosive range of hydrogen is massive - far, far beyond the range of methane, which we already consider hazardous enough that we require annual inspections of gas appliances and add a scent chemical to the gas so that a leak is immediately apparent to everyone.
    These days most things run on grid power. Things get plugged in either all the time, or they've got a perfectly adequate lithium ion battery in them that can be charged as needed. Or they have a small enough power draw that it's still reasonable to use old school nickel-cadmium or nickel-metal-hydride batteries and just replace them occasionally. There's 2 major things that don't run on grid power: generators and cars.
    Generators are probably the best candidate for fuel cell technology. They're often used for emergency backup power in critical infrastructure - keeping life support systems on in hospitals, stuff like that - which means they're rarely used, so you'd need to work out a good long term storage plan for hydrogen, but that's feasible...even if the answer is just check the pressure on the tank every 6 months, and get a resupply when it drops below X. They're also regularly used in construction sites, where grid power has not yet been made available, but construction workers are usually already pretty smart about not doing things that generate sparks near their generator...the big difference is the fuel cell generator is an explosion hazard instead of a fire hazard.
    And then there's cars. Well, vehicles in general. Some vehicles operate in extremely controlled environments - the haul trucks at mines could swap out the diesel generators that run their wheel-mounted electric motors for fuel cells without much change, because you tend not to get in car accidents when driving a truck that's bigger than any tank at 5 miles an hour. But by far the biggest category here is the regular street-legal stuff. And this is the problem. Spark management is pretty easy when you're in a safe environment, but...have you seen what car accidents do to vehicles? Take a look at any significant car accident and tell me there were no sparks made in that process. Sparks are already an issue in car accidents - the first thing they did to my car in the car accident I was in (I was fine and got out on my own, presumably cutting people out of the wreckage comes first if it's needed) was popping the hood and disconnecting the battery, just in case it sparked and lit fuel that might be leaking. That concern gets a whole lot more exciting when it's hydrogen because when you pour gas out and strike a match, odds are the gas is going to put out the match rather than start burning, Hydrogen, meanwhile, will happily explode, if it's not already done so.
    There are engineering solutions to this: ways you can build the hydrogen tank to be stronger, anti-spark technology, etc. But with everything that you solve with engineering, you have to accept that it will occasionally fail. Sometimes the power goes out. Every year, some poor bastard has to figure out how to get a leak in their roof fixed when the first big storm rolls around. Literally everything engineers design breaks sometimes. Engineers do their best to minimize the odds of that being a catastrophic failure. The roof that springs a leak lets a few litres of water through, it doesn't *disintegrate.* The power goes out, and maintenance crews figure out what's happened and fix it within about an hour, etc. But, inevitably, there are circumstances that go beyond what engineers can reasonably design for. Tornadoes tear roofs of buildings...and buildings off foundations. Coronal Mass Ejections wipe out critical grid infrastructure that cause power outages for huge swaths of territory disrupting the lives of millions for days. And....a bad enough car accident will probably overcome any engineered safety system that is used to suppress hydrogen explosions. The best way to not have your car explode is to not put explosive stuff in your car.
    This is a big problem for hydrogen fuel cell technology becoming a mainstream solution because the street vehicle energy problem is the single biggest problem, by a significant margin, that portable energy storage options have to overcome.

      2: Hydrogen is substantially more explosive then methane, which is dangerous enough that we put a really pungent additive in it so we can detect leaks. Most cars that breach the fuel tank don't explode, because gasoline takes really good conditions to burn rapidly. That's why fuel injectors are so damn complex, they're getting the fuel-air mix just right.
      Here's some excerpts from a lab safety document on hydrogen:
      "Hydrogen gas forms explosive mixtures with air if it is 4-74% concentrated"
      "Hydrogen gas leaking into external air may spontaneously ignite"
      "hydrogen fire, while being extremely
      hot, is almost invisible, and thus can lead to accidental burns"
      Conversely gasoline, you can literally drop a lit match in a puddle of and it will probably go out. The difference is going from a chemical that stores energy but only burns under relatively good conditions to one of the most reactive substances known.

    Big fly in the H2 argument: While the energy density is impressive at 120 MJ/Kg (gasoline is about 45) the transport density of H2 (for a given pressure) is 7X less than methane. What does this mean? A given pipeline (which is pressure limited) can't transport as much energy in H2 as methane (55 MJ/kg) by a factor of 3.66 or so. Likewise for large storage vessels - they would have to be much larger for a given pressure of containment or made to handle higher H2 storage pressures (more expensive).
    H2: 120 MJ/Kg, 0.09 Kg/m^3
    Ch4: 55 MJ/Kg, 0.72 Kg/m^3.
    One trick I've heard mention of (but I don't know if it is in practice) is to co-transport H2 along with CH4 in pipelines - this way the much smaller H2 industry can "piggyback" on the well established network of NG pipelines in North America and Europe (and elsewhere, I presume).

    To my mind there is too much R&D money going to hydrogen research from the fossil fuel industries that see its potential as a replacement in their control and distribution business model at the scale they serve today. I see its niche uses at a much reduced scale, that of suppliers to the steel industry and for the few transport modes that cannot be served with battery storage methods, like long haul airliners. Short-haul aviation and virtually all land transport can be electrified more economically without siphoning off energy for hydrogen electrolysis.
    Those fossil fuel companies machinations remind me of the coal companies of my 1950s youth in Connecticut who dominated the home heating fuel business while the Texas based oil interests were attempting justify their recent pipeline to the region by getting folks to use "modern" heating oil instead of the dusty old coal that had to be hand shoveled into furnaces and was losing the business of fueling steam locomotives. The coal companies fought back, but were supplanted by mergers, because the oil interests were flush with money from the profits they made in WWII production. They actually paved a short street with gold leaf coated chips for my town's 300th anniversary celebration to buy good will publicity for their business. That business was dependent on heating wastefully insulated older homes, and though the oil was marginally better, People did not have to crack a window in winter to prevent carbon monoxide poisoning from a neglected coal fire late at night, the inefficiencies built into over consummation were good for their business model just as our fuel oil uses today tend to be.
    The transforming of our energy use patterns to a more efficient one needs to be done efficiently as well, and hydrogen will never be as efficient for the transport technologies with a reverse version of the fuel cells used to make hydrogen in a stationary process which separates hydrogen electrolysis into becoming a secondary market. BEVs have built in generators that amount to as much as 1/3rd of their energy for transport on board the vehicle. Even even the shorter range propeller driven electric aircraft can use on board regeneration from their frequent descents. That leaves the long range steady altitude flights as the only reasonable use of hydrogen fuel for clean flights. Let the clean steel production and long haul transport survive on the hydrogen from surplus renewable electricity that gets produced.

      Hydrogen is actually a major feed stock in the production of steel in a carbon neutral way and in general for the chemical industry. So regardless of what certain businesses might hope to use it for, like say cars, it will for the foreseeable future still be pretty important as such for various important industries.
      In that sense getting cheaper Hydrogen production is a good thing, as it will help out compete the hydrogen currently being produced by stripping it from gas.
      So I don't know what the most appropriate amount of hydrogen research would be, but regardless of transportation, we will still be able to make good use of improved technology here by reducing waste in various industrial production.

      I have seen accusations and conspiracy theories about fossil fuel companies supporting hydrogen. The only "evidence" is some lobbying for projects in the UK about a year ago by oil companies. I don't see why that makes hydrogen as part of humanity's future a bad thing.

    It feels like these videos just saturate my future fatigue and on that I'm decided. I've been watching stories like this for over 40 years and the number of things that came to fruition seem astronomically low. It would be nice to see a video about something that went from the very futuristic stage into a viable solution.

      The reason is the government makes too much money off oil and gas. Whatever the next technology is will not be allowed unless the government regulates and makes money off it. Period. Always been that way. What other everyday things have not changed in 100 years? Only the internal combustion engine that needs gas and oil to run. Coincidence?

    I'd like to see these incremental improvements in hydrogen gas generation eventually make Roger E. Billings' vision of the "hydrogen homestead" practical for everyman, where people could use solar panels to generate electricity for daily use and also make hydrogen gas, stored at low pressure in metal hydride tanks, for domestic cooking, space heating and water heating during periods when the sun isn't shining.

    Interesting, Matt. One thing you didn't mention was white hydrogen - ie that which exists underground and can simply be mined. It constantly renews itself and exists in large amounts all over the world. Extracting it without damaging the environment is the tricky part but hopefully not impossible. Be great if you could do a video on this, and also on hydrogen powerpaste.

    I believe "cracking" the methane molecule for hydrogen production will prove to be more efficient and less costly in the long run. By producing useful hydrogen for energy, capturing carbon in a solid state, producing oxygen as well as removing a very powerful greenhouse gas from the environment a wasteless process that does not consume precious resources (water being most precious) can be achieved. Currently the German research conducted by Karlsruhe Institute of Technology shows the most promise. Any VC's interested in scaling it?

      if you extract your hydrogen knowledge from this channel.. you would become as ignorant as he is.
      Hydrogen is the future.. 95% of what he said is WRONG... he even contradict himself here 10:43 to 10:52
      You would keep trusting this guy?

    Just the compression, storage and transport of liquid hydrogen is not remotely green. Cleaning up the extraction process is a good step though if it works out.

Os seus vídeos, para um grande curioso como eu, é de grande valia, amo aprender e saber das coisas, valeu 👏👏👏👏👏👏👏👏

    Batteries, hydrogen, ammonia all use electricity. And there is a couple of issues there. 1. The current grid is not updated to handle the extra load. 2. The west coast is running out of water to make hydro power.

    The more I look at electric cars, the more I see hydrogen as the key to finally busting them wide open. Lithium ion batteries are never going to be more than a niche.

    • @rogerphelps9939
      @rogerphelps9939 2 года назад +3

      Wroing on every count. The hydrogen route wastes far more energy than charging batteries. The fuel cells are easily poisoned and do not last very long. Hydrogen requires a lot of very expensive gear to handle it and those are just a few of the many reasons why hydrogen cars will never ever take off; in fact the level of hydrogen car production is negligible and decreasing. Lithium ion batteries are already mainstream, just look around. In 8 years time the sale of new internal combusyion engine cars in the UK will be banned and lithium ion battery vehicles will completely dominate.

    Is there a frequency of sound that would cause forming bubbles to release?
    It will be great to see hydrogen replace bunker fuel in ships, if the engines can retrofitted at an affordable cost.

    • @dwc0
      @dwc0 2 года назад

      The frequency to be applied is in the electric charge itself and tuned to the natural resonant frequency of the H2O molecule, as discovered by Stanley Meyer decades ago.

    As someone who loves the feel of ICE powered cars i really hope we get cheep efficient hydrogen as we could convert ever car on the road today to hydrogen without the Toxic mining of lithium for batteries as well as the battery waste as electrodes degrade, if Hydrogen gets down to $1.50/kg it would be energy wise gasoline going down to 1$ a gallon

    I don't think everyone was complaining about topics of hydrogen, just the postings of *CLAIMS* over how they been *attempting to use* hydrogen on your research fetching. Than making your vids, like it was a break though fact. When thd facts, is STILL Undesided.

  • @grafin4769

    I'm not a scientist (and often barely understand it), but I had heard about a new technology using a simple process of using magnetic discs to capture and store hydrogen in a low cost and easily distributable way. The proprietary technology was being developed by a private company called Plasma Kinetics. Have you heard anything about this technology and whether this company is making any progress?

  • @chrismcdonnell7448
    @chrismcdonnell7448 2 года назад +1

    I've believed in hydrogen power since I first saw Stanley Meyer's Hydrogen fuel cell work in person in the mid 90's. If only the oil companies would get out of the way, we could have had fuel cell technology before now.

    • @701983
      @701983 2 года назад

      Stanley Meyer's fraud didn't include a fuel cell, AFAIK. Just an electrolyzer-unit.
      And it didn't really work of course. You can't produce hydrogen with excess energy from hydrogen combustion (perpetuum mobile).
      Despite a number of swindlers, who claimed to have invented such a device. Like Stanley Meyer or Charles H. Garrett.

    • @dwc0
      @dwc0 2 года назад

      Bingo! After all this time and still almost no one is talking about how the resonant frequency of H2O can be exploited for efficiency gains of orders of magnitude. But this is much bigger than oil companies. Cheap, abundant energy cannot be allowed to become mainstream as it would destabilize the entire political power structure of the world.

    Im working with a Finnish Company who make industrial gasses of all types , including as part of this process oxygen , acetylengas etc and guess what a by rpoduct is H2 !! Yes they throw one and a half million liters per month out of the window , lierally because they have no customers for large units of this gas . All large gas producing companies , who produce industrial gasses have the same element over when using the electrolysis production . Would be interesting to find out what they do with it !! Its a threat to the oil companies and I guess its swept under the table ! And the idea goes up into thin air ! Dont beleive me ? Do your research ask around you will be astounded !! Good luck
