'Storing hydrogen = difficult, thus cars will run on batteries'. Great analytic conclusion. Going to the moon was an easy job, if it had it been difficult it would have never happened. Off course profit driven society goes for the easy option to excavate entire islands, no even countries (Republic of Madagascar), in search of precious resources such as Nickel / Cobalt / Lithium to store energy in an efficient way. Because yes, things need to be easy to do so.
Oh wait, just remembered, Pratt and Whitney developed fuel cells that were part of Apollo missions. You know, the missions with their sole mission to go to the moon. airandspace.si.edu/collection-objects/fuel-cell-apollo-4

hydrogen is the only right variant for future. No other variant ! But we are developing approach, which is not exact now. There must be 2 waves for hydrogen : 1/BUILD HYDROGEN PRODUCTION FACTORIES ON SITES OF RENEWABLE ENERGY STATIONS. 2/ SMALL CARS NEED TO LOAD HYDROGEN BY EXCHANGING WHOLE COMPRESSED HYDROGEN BALLOONS. We are wrong because we do not firstly build enough hydrogen production factories on sites of renewable energy stations. We are wrong because we are trying to build network of hydrogen loading stations, which are COMPLEX AND EXPENSIVE. We must change our approach. We should use hydrogen as energy storage method for renewable energy stations first. Then we should load hydrogen for usual cars by exchanging whole standard sized compressed hydrogen gas balloons. So It is very simple and not expensive to make the global net of hydrogen supplying stations. Any normal mini shops can be a hydrogen supplying point by storing standard sized compressed hydrogen gas balloons. We do not have to use liquid hydrogen, which is difficult to collect. But we can use compressed hydrogen gas, which is not so much different in weight by comparison with liquid hydrogen. Hydrogen is the best solution of energy storage for all energy stations now, for example, for nuclear energy stations, for renewable energy stations. Just install ready hydrogen production modules, and install independent hydrogen fuel cell modules in adjacent areas. Use compressed hydrogen gas at first time instead of liquid hydrogen. And the last thing to notice is that, hydrogen is not more dangerous than other gases and petrol. Hydrogen has big energy storage capacity, but when burning hydrogen in accidents, IT DOES NOT CREATE ACOUSTIC DESTRUCTING WAVE TO ENVIRONMENTS. It means that hydrogen burning is less destructive than gasoline burning.

when a conductivity of material is high, we use a electrolysis method to break a bond of oxygen and hydrogen. however, then a conductivity of material is low, we use a photocatalyst .
Very good educational video. I'm only unsatisfied about the example chosen for the greenhouse effect: methane is about 20 times more efficient of a greenhouse gas than carbon dioxide, therefore it is one of the rare cases where an exothermic reduction-oxidation reaction (i.e. Burning) actually reduces the greenhouse effect.
What if we use Hydrogen fuel cells to power our homes instead of cars? We usually get water through pipe, we can generate electricity using few solar panels. Using this electricity we can create Hydrogen for fuel cells and generate much more electricity needed for entire house. (we can perhaps use solar power itself to generate electricity for entire home)
conceptually yes but the catalyst used to seperate H2 is platinum and thats really expensive so it just makes more sense to use solar panels for a home because you dont need a consistent output
Hydrogen is used better for storage. Why would you need hydrogen storage in your house if you can get it from the power plant much more efficiently? However, it could be nice if you produce electricity by solar panels and a wind turbine in a remote house with no connection to the power plants and has a water source nearby. What happens? You use the electricity produced from sources on daytime and it is windy. Excess electricity(Electricity can't be stored wo/ batteries) will be turned into hydrogen by an electrolyzer and when in need, a fuel cell (there are lots of options for stationary fuel cells, IDK which one is the best) will turn it into electricity and you will use. Why wouldn't I use a battery instead? Because, think of your battery driven devices, when kept at full charge or it is empty, the chemical balance in your battery will be disrupt and it will be damaged irreversibly and performance will be diminished. It will have higher impact, lets say, when you don't use that home for a year. In contrast, the degradation of the fuel cell will be much lower and hydrogen stored in the tank will be perfectly clean and in need, it'll work flawlessly. TL;DR: Hydrogen must be used for electric storage, not producing electricity.(At least, on Earth)
Actually the energy comes mainly from the weakly bonded Oxygen - the bonds in hydrogen H-H and water H-O-H are all strong so it is only by replacing the weak O=O bond with the strong H-O-H bonds thaat energy becomes available.

The only reason to start turning water into hydrogen, is that your solar array has fully charged your batteries and is sitting there idle. In large systems, this is a lot of the time. That extra energy is genuinely free - you have it, you waste it, and you don't care that you had it - that's "free". Make hydrogen with it.
Nice video, are you aware that water can form highly diamagnetic molecules of multiple H2O sets? This can happen with just cavitation, but ionizing it first stimulates the formation. This type of water molecules becomes a gas above minus 158 deg C. at 5 atmospheres and standard (normal room temps) temps the diamagnetic forces making it a gas can be overcome and it will condense, releasing up to 6 times the amount of electricity as H2 fusing with O2. forming liquid water.... pretty cool huh? could save the future of fuel cells, don't you think? Party on Dudes, be good to each other.
Hydrogen can be compressed like any other gas, and can be made in situ at fuel stations and even houses. If a Wind or Water turbine( perhaps a micro hydro turbine powered by water mains pipes, which are already being installed in a few places). Combined with some Solar for back up. It would be very easy to make and compress Hydrogen at fuel stations. The Orkney Islands are using their excess Wind energy to split water to make Hydrogen, which they use in a Fuel Cell at the ferry port to power the Port and associated buildings etc, they also use the heat generated to heat the Port buildings. The excess Hydrogen is sold to the mainland and brings an income to the Island. They plan on using their Hydrogen in Fuel Cells to power the Ferries to the mainland when the current Ferries come to the end of their service life. Here’s a link from one of the Islanders who explains how it works. th-cam.com/video/Rybpaqhg5Qg/w-d-xo.html
What if you wanted to use hydrogen to power a ship? IE we take a 40 meter long catamaran with plenty of space on the deck for solar-panels + I believe you can buy sails who also have solar-cells in them. Would that be enough electricity to create Hydrogen to power 2 engines, pushing a pair of waterjet propulsion systems? Since you dont have to sail every day (unles crossing big oceans ofc) you could bask in the sun for a week, then travel until you run out of fuel and then repeat? What would be the biggest problem(s) with this idea you think? And aprox.. how much would you guess such a system (not including the ship, waterjets and engines, just the hydrogen system)) would cost?
I guess what I really want to know is, should you just use the electricity to power electrical engines, or can you get more power by using the electricity to make hydrogen and then burn that?
that's what the one company did with a ship they made. They have wind and solar powering electrolysis chamber and use hydrogen from water to power the ship.
if it were a sailing catamaran there'd barely be space for enough solar panels to power the cabin lights.. if it weren't a sailing ship, then you'd be trading like a week of good sunny days for a couple hours of navigation (at decent speed, and I'm only guessing). That would be absolutely impractical. And this is of course without the losses involved with making hydrogen and then reconverting it to electricity. In this scenario you'd be better off using batteries. Proposers of hydrogen would encourage you to picture a different scenario instead. Imagine a future in which electricity is extremely cheap and extremely abundant, but fluctuating because nearly all of it is made from inconstant sources like wind, solar, tidal etc. At this point the only problem would be how to store this energy to use it during the night and in electric vehicles and boats and trains and maybe even on planes. Well in this scenario hydrogen makes for a pretty compelling argument, because the inherent inefficiencies of the process become irrelevant - remember that electricity is dirt cheap and that the only real issue is how to store it. The energy loss involved in producing the hydrogen would then become competitive with the losses involved with converting electricity into different voltages and move it around the grid over long distances (we already waste about 20% like that nowadays). In any scenario, hydrogen fuel cells also much more practical than batteries for the user (be it a small car or a large cargo ship), and are also poised to be a lot less polluting. Therefore I am not as sure as this professor is about the tech of choice for the future of transportation, but I think that future of hydrogen is tightly bound to the adoption of renewables. The eventual raise of fusion power would most likely disrupt any development in this direction.
Is the labelling correct at 2:06? Here's why I'm asking: (I am genuinely confused here, so please help someone...) Firstly, the material that an electrode can be made of is stated to be carbon, which is labelled as the central part of the HFC. But that to me, doesn't seem to make sense, as an electrode, is a conductor where electrons enter to, or exit from, as part of travelling the alternate route to power an object. In the diagram, what is stated to be 'platinum/nickel', should be the electrode right? Furthermore, the central part is only shown to be a single object, and not two, which is the number of electrodes required for a current (along with an electrolyte) in such a setup. So that makes me think what is labelled as 'platinum/nickel' should be the electrodes. Also, (maybe this is too specific of a detail, idk) the wiring is shown to be surrounding the central part of the hsc, which would make me think more that the diagram might be wrong. (As i think it would make sense for the wiring to be after the anode, to allow for electrons to enter, and then conduct through the wire and vice versa for the cathode.) Plus, I'm a bit stuck on another thing, where I'm not sure what the layer that the protons move through (being the central object) would be called. Would it be an electrolyte? Or is it a proton exchange membrane, which is something I've seen in other stuff, or is it both? I'm not really sure on this and I don't even know if one involving the exchange membrane would even be another kind of hsc or something. Help, please...
You are right - the label 'carbon' should on the two sides supporting the platinum, not in the middle, which, as you rightly say, is the electrolyte carrying the H+ ions. The porous carbon allows the gases (H2 and O2) to reach the platinum catalyst. Sorry for the confusion and well-spotted Jens!
Lots of processing goes into hydrogen about the only thing I didn’t like about hydrogen was the explosive effects and batteries are near solid state level with out blowing up / you can use algae to produce hydrogen and make more efficient hydrogen stations/ with discharge water disposal and electrolysis in case you need more hydrogen or algae hydrogen overflow and balance it out with ultra capacitors
thank you for the explanation, recently this kept appearing in the news. but im glad the cheap electricity from solar can help with hydrogen technology
The more reactive metal (eg Zn) will lose electrons and become +ve ions forming the anode. At the cathode the electrons arrive (having travelled round the circuit) and the less reactive metal (eg Cu++) will plate out as the electrons neutralise the ions.
I wonder how daniel dengil a Filipino inventor manage to run his toyota corolla with his hydrogen generator? He didnt use any tanks to store his hydrogen as his hydrogen generator provides enough gas needed by the engine. If his invention can produce large amount of hydrogen then it can be used for the fuel cell and the fuelcells product which is water can be use to its invention to separate the h2o thus making it a cycle.
What about recycling the waste water vapour and recycling it in the car, thus eliminating the fuel cell? The water could be split inside the car, allowing you power the car on water and needing to only refuel when all the hydrogen and oxygen is either leaked or turned into byproducts and heat
Your idea seems to be similar to that of a perpetual motion machine. The thing is that we need to split the water into hydrogen and oxygen for fuel cells. This requires energy. If you were to reuse the energy produced by the fuel cell to in turn split water molecules for the fuel cell, there would be no excess energy for any practical use. Tl;dr You can't get any more energy than what you put in initially for the splitting of the water molecules as that is the energy we get out of the fuel cell.
In order to turn water into hydrogen and oxygen you need large amounts of energy. So the car would need an energy source to power a machine to turn the water into gas, then it would need the fuel cells themselves to power the car. You'd also need a large amount of storage for both systems. This would create weight. the excess weight would mean needing larger amounts of energy. It wouldn't be efficient.
As I understand it, you're suggesting to split water (using the waste water from the fuel cell) inside the car. The issue with this is that the fuel cell essentially produces electricity for an electric motor, and splitting water is a very energy intensive process, so I doubt there will be enough electricity "left over" for electrolysis to work as well as running the motor. Not an expert on this field mind, but that would be my feeling
I like the video. I love learning about hydrogen fuel cells. This is the way we should go. But the thing that stopped me from watching the rest of this video is the sound of his lips smacking and all the squishy mouth noises he is making. I couldn't take it. Once you hear it you cant unhear it. Video was informative but his mouth was so moist that it was all I could hear. Sorry
You can but the thing that makes fuel cells so useful is the fact that it’s BY-PRODUCT is water. And therefore doesnt need water for the actual reaction to take place.
We can in short, but it's not excellent energy conversion. The biggest problem by FAR and the one that is turning people away from H is the storage, creating 5 kilos of liquid hydrogen from water using electrolysis would cost (at 15c per Kwh) around 30 dollars, so 30 dollars to fill a H2 car, but it has to be stored at 200 Bar... that's the problem,. 200 bar is huge... Your average car tyre is what, around 34 to 40 PSI or around 2.4 to 2.7 Bar. The current H2 cars from Tokyo run on 200 bar or 2900 PSI... It's because H is the lightest element it takes a lot of pressure to squash it together to make it possible to get an equivalent range of a full tank of gas. Can you imagine what kind of monstrous compressor you would need in your back garden to do this for say home production, and if anything went wrong under those huge pressures and we got leaks, one spark to the equivalent of 1 litre of H of gas... and you lose your house. You cant use steel tanks either, as H turns steel brittle over time and can even leak through it, so you need a very specialized carbon\steel ceramic inlaid tank.. very expensive. That is also why it's very expensive to transport.
DON'T WATCH if you're interested in the actual fuel cell process , as out of the 5 minutes of video, only 20 seconds explain the what is going on inside a fuel cell!
Problem with hydrogen fuel cell it's not easy to obtain hydrogen. On top of that splitting hydrogen from water isn't cheap either. Unless we are using renewable energy to do that. But then arises the Question why not simply use electric car?
We NEED the current Internal Combustion Engine(ICE) Vehicles to Sequester Carbon!. - We can( and need to) use the world’s ICE vehicles to suck CO2 out of the atmosphere by running them on ‘Carbon Negative Algea Bio Fuel’,the Internal Combustion Engine( ICE)was responsible for much of the atmospheric CO2 due to them running on Carbon ‘Positive’( or Carbon based) fuel. Now if those same Engines were run on a Carbon Sequestering Bio Fuel it would mean the more people drive the more CO2 would be sucked out of the Atmosphere. The Algea Bio Fuel is grown using waste watert so saving lots of energy that is currently used in energy intensive waste water treatment. Plus from every gallon of Algea Bio Fuel, 10 pounds of nutrient rich( high in Omega 3 etc) Carbon residue is produced and permanently removed from the atmosphere. Photo Bio Reactors( PBR) can grow Algea Vertically in glass tubes and are easy, cheap and quick to build. It is possible to roll out PBR across the country in every village, town, neighbourhood and city in just a few years, we MUST make this transition asap. Electric Vehicles( EV) are not the answer as we don’t have the time to build billions of new vehicles( of whatever type) also the vast amount of resources and energy to make them could finish us off. Also EV are not Sustainable as they rely on non renewable Lithium, Cobalt, Manganese etc which is very destructive when mined as they use strip/open cast mining and uses large amounts of water in evaporation ‘pools’in Arid Regions. Also EV only cause emissions( in their manufacture from Mines, to Road), they can’t be used to sequester CO2 as the ICE could, and seeing as roads take up a lot land we NEED to utilise that land as a Carbon sink. Carbon Negative Algea Fuel would mean in effect we would be using the world’s ICE’s as Carbon Capturing machines. Another positive to rolling out PBRq is it would create millions of new local Green jobs and bring £millions to communities and regional economies, and could fund the transition to a Sustainable future. So Algea Bio Fuel is a viable, positive low tech solution, in every aspect its a winner!.
I believe the final assumption here is premature, hydrogen technology is advancing as is technology in general. Batteries may be the solution at some time in the future, but in a form that we could scarcely imagine at present.
@1:37 - @1:42 the illustration is incorrect. the arrow for the flow of ions should be right to left (not left to right). obviously you've got several people working on these videos, and they cant all be expected to know the science! you should employ me to fact check :0 :)
Sorry, you are wrong here - the zinc +ve ions flow from the zinc anode, through the electrolyte towards the copper cathode. Of course the -ve ions in the electrolyte will flow from right to left, but the voice over says "movement of metal ions through the solution" and these flow in the direction of the arrow.
also 2:50 methane being converted to CO2 is not adding to the greenhouse effect. methane is a much stronger greenhouse gas. your videos need a more scientific editor. #me
The methane is natural gas, and is not purposely released into the atmosphere. Using it as a source of hydrogen is not 'green' because it is equivalent to burning the methane in a normal furnace or engine - forming H-O-H and O=C=O, thus releasing new carbon dioxide into the atmosphere.
He is speaking rather moistly.
can't agree more... Good video... but too distracted by his moist speaking...

Therefore I am not as sure as this professor is about the tech of choice for the future of transportation, but I think that future of hydrogen is tightly bound to the adoption of renewables. The eventual raise of fusion power would most likely disrupt any development in this direction.
That is a great video but please don't kiss your mic while talking

Is the labelling correct at 2:06? Here's why I'm asking: (I am genuinely confused here, so please help someone...)
Firstly, the material that an electrode can be made of is stated to be carbon, which is labelled as the central part of the HFC. But that to me, doesn't seem to make sense, as an electrode, is a conductor where electrons enter to, or exit from, as part of travelling the alternate route to power an object. In the diagram, what is stated to be 'platinum/nickel', should be the electrode right? Furthermore, the central part is only shown to be a single object, and not two, which is the number of electrodes required for a current (along with an electrolyte) in such a setup. So that makes me think what is labelled as 'platinum/nickel' should be the electrodes. Also, (maybe this is too specific of a detail, idk) the wiring is shown to be surrounding the central part of the hsc, which would make me think more that the diagram might be wrong. (As i think it would make sense for the wiring to be after the anode, to allow for electrons to enter, and then conduct through the wire and vice versa for the cathode.) Plus, I'm a bit stuck on another thing, where I'm not sure what the layer that the protons move through (being the central object) would be called. Would it be an electrolyte? Or is it a proton exchange membrane, which is something I've seen in other stuff, or is it both? I'm not really sure on this and I don't even know if one involving the exchange membrane would even be another kind of hsc or something. Help, please...
You are right - the label 'carbon' should on the two sides supporting the platinum, not in the middle, which, as you rightly say, is the electrolyte carrying the H+ ions. The porous carbon allows the gases (H2 and O2) to reach the platinum catalyst. Sorry for the confusion and well-spotted Jens!
titanium dioxide to store hydrogen as metal, when exposed to uv gives out mostly oxygen, some hydrogen
Titanium is quite hard to mine. And maybe, it would cost more energy in order only to get the material..
Please more advance detail, such as dc voltage electrolysis minimum, electrode type and how to make. Thank you
Research further and read
Lots of processing goes into hydrogen about the only thing I didn’t like about hydrogen was the explosive effects and batteries are near solid state level with out blowing up / you can use algae to produce hydrogen and make more efficient hydrogen stations/ with discharge water disposal and electrolysis in case you need more hydrogen or algae hydrogen overflow and balance it out with ultra capacitors
Good channel
Thank you!
thank you for the explanation, recently this kept appearing in the news. but im glad the cheap electricity from solar can help with hydrogen technology
This is awesome
1:20 I am not exactly sure, but is Zinc suppose to be the cathode while Copper the anode? Thank you!
No - electrons are liberated at the anode as a metal ionises, and metals are deposited on the cathode as electrons are given to the +ve ions.
what sort of conclusion was that
Like it ❤️ I will be there at hurts
Can you pls tell me all the software that you use to create these awesome videos?
Hydrogen and oxygen are highly explosive by themselves.
Neither gas ON ITS OWN is explosive. It is the mixture allowing them to react that makes it explosive.
Hey guys, Question how pure is the byproduct Water?
doesn't the more reactive metal become the negative electrode: cathode?
The more reactive metal (eg Zn) will lose electrons and become +ve ions forming the anode. At the cathode the electrons arrive (having travelled round the circuit) and the less reactive metal (eg Cu++) will plate out as the electrons neutralise the ions.
I wonder how daniel dengil a Filipino inventor manage to run his toyota corolla with his hydrogen generator? He didnt use any tanks to store his hydrogen as his hydrogen generator provides enough gas needed by the engine. If his invention can produce large amount of hydrogen then it can be used for the fuel cell and the fuelcells product which is water can be use to its invention to separate the h2o thus making it a cycle.
Why this video so underratted
What about recycling the waste water vapour and recycling it in the car, thus eliminating the fuel cell? The water could be split inside the car, allowing you power the car on water and needing to only refuel when all the hydrogen and oxygen is either leaked or turned into byproducts and heat
Interesting
Your idea seems to be similar to that of a perpetual motion machine. The thing is that we need to split the water into hydrogen and oxygen for fuel cells. This requires energy. If you were to reuse the energy produced by the fuel cell to in turn split water molecules for the fuel cell, there would be no excess energy for any practical use.
Tl;dr
You can't get any more energy than what you put in initially for the splitting of the water molecules as that is the energy we get out of the fuel cell.
In order to turn water into hydrogen and oxygen you need large amounts of energy. So the car would need an energy source to power a machine to turn the water into gas, then it would need the fuel cells themselves to power the car. You'd also need a large amount of storage for both systems. This would create weight. the excess weight would mean needing larger amounts of energy.
It wouldn't be efficient.
a lot of energy is required to split the water molecules, so it couldn't be done within the car.
As I understand it, you're suggesting to split water (using the waste water from the fuel cell) inside the car.
The issue with this is that the fuel cell essentially produces electricity for an electric motor, and splitting water is a very energy intensive process, so I doubt there will be enough electricity "left over" for electrolysis to work as well as running the motor.
Not an expert on this field mind, but that would be my feeling
I've found a good explanation at last.
Excellent! Glad to hear it!
Why does hydrogen loses its electron while moving through membrane??
I like the video. I love learning about hydrogen fuel cells. This is the way we should go. But the thing that stopped me from watching the rest of this video is the sound of his lips smacking and all the squishy mouth noises he is making. I couldn't take it. Once you hear it you cant unhear it. Video was informative but his mouth was so moist that it was all I could hear. Sorry
ikr
I didnt even notice it until you mentioned it. Now I can't unhear it...
I shouldn't have scrolled down to see the comments...
it was satisfying
So let me get this straight we cut water into hydrogen and oxygen just so we can turn them back into water again?
remember that when hydrogen and oxygen are separated energy is STORED. Recombining them transfers the energy usefully when and where it is needed.
hope the problem of its transpotation is solved fast earth is already chocked carbon dioxide enough
Then how about we take hydrogen peroxide
Why can't we use hydrogen from electrolysis of water.
It is too expensive
you can. Your car might explode if it crashes though. Cause Hydrogen with pressure or heat is a bomb.
You can but the thing that makes fuel cells so useful is the fact that it’s BY-PRODUCT is water. And therefore doesnt need water for the actual reaction to take place.
Also water cant be an electrolyte if its not an ion with a charge because then it cant be attracted to the electrodes
We can in short, but it's not excellent energy conversion. The biggest problem by FAR and the one that is turning people away from H is the storage, creating 5 kilos of liquid hydrogen from water using electrolysis would cost (at 15c per Kwh) around 30 dollars, so 30 dollars to fill a H2 car, but it has to be stored at 200 Bar... that's the problem,. 200 bar is huge... Your average car tyre is what, around 34 to 40 PSI or around 2.4 to 2.7 Bar. The current H2 cars from Tokyo run on 200 bar or 2900 PSI... It's because H is the lightest element it takes a lot of pressure to squash it together to make it possible to get an equivalent range of a full tank of gas. Can you imagine what kind of monstrous compressor you would need in your back garden to do this for say home production, and if anything went wrong under those huge pressures and we got leaks, one spark to the equivalent of 1 litre of H of gas... and you lose your house. You cant use steel tanks either, as H turns steel brittle over time and can even leak through it, so you need a very specialized carbon\steel ceramic inlaid tank.. very expensive. That is also why it's very expensive to transport.
DON'T WATCH if you're interested in the actual fuel cell process , as out of the 5 minutes of video, only 20 seconds explain the what is going on inside a fuel cell!
can I have the script of the video please...
So not so green as they make out then. Hydrogen has to be produced which produces co2
Hopefully the hydrogen will be generated by green electricity in the future
Problem with hydrogen fuel cell it's not easy to obtain hydrogen.
On top of that splitting hydrogen from water isn't cheap either.
Unless we are using renewable energy to do that. But then arises the Question why not simply use electric car?
narrated bu Sean Connery
Even many new petrol automotive engines, like Honda L15B and Volkswagen EA888 Gen3B, achieve the thermal efficiency of 37 percent...
Why does he constantly sound like he is salivating
Same that kept bugging me the whole time
But Japan believe in using fuel cell rather than battery for their EV. Any comment?
Liquid hydrogen ignited can produce radiation
We NEED the current Internal Combustion Engine(ICE) Vehicles to Sequester Carbon!. - We can( and need to) use the world’s ICE vehicles to suck CO2 out of the atmosphere by running them on ‘Carbon Negative Algea Bio Fuel’,the Internal Combustion Engine( ICE)was responsible for much of the atmospheric CO2 due to them running on Carbon ‘Positive’( or Carbon based) fuel. Now if those same Engines were run on a Carbon Sequestering Bio Fuel it would mean the more people drive the more CO2 would be sucked out of the Atmosphere. The Algea Bio Fuel is grown using waste watert so saving lots of energy that is currently used in energy intensive waste water treatment. Plus from every gallon of Algea Bio Fuel, 10 pounds of nutrient rich( high in Omega 3 etc) Carbon residue is produced and permanently removed from the atmosphere. Photo Bio Reactors( PBR) can grow Algea Vertically in glass tubes and are easy, cheap and quick to build. It is possible to roll out PBR across the country in every village, town, neighbourhood and city in just a few years, we MUST make this transition asap. Electric Vehicles( EV) are not the answer as we don’t have the time to build billions of new vehicles( of whatever type) also the vast amount of resources and energy to make them could finish us off. Also EV are not Sustainable as they rely on non renewable Lithium, Cobalt, Manganese etc which is very destructive when mined as they use strip/open cast mining and uses large amounts of water in evaporation ‘pools’in Arid Regions. Also EV only cause emissions( in their manufacture from Mines, to Road), they can’t be used to sequester CO2 as the ICE could, and seeing as roads take up a lot land we NEED to utilise that land as a Carbon sink. Carbon Negative Algea Fuel would mean in effect we would be using the world’s ICE’s as Carbon Capturing machines. Another positive to rolling out PBRq is it would create millions of new local Green jobs and bring £millions to communities and regional economies, and could fund the transition to a Sustainable future. So Algea Bio Fuel is a viable, positive low tech solution, in every aspect its a winner!.
water exists
1:02 after electrolysis pure oxygen is released into the atmosphere. pure oxygen is toxic??!
It is not pure if its in the atmosphere it gets immediately diluted.
It is more like, 'let be free' instead of put 'em in a tank or something, fore the sake of an abundand oxygen demands..
You need to cut out mouth noises on the audio edit
А кім бар мында 😂
Good info comes along with battery propaganda :/ There s already too little Cobalt on the planet. Even just for Volkswagen.
I believe the final assumption here is premature, hydrogen technology is advancing as is technology in general. Batteries may be the solution at some time in the future, but in a form that we could scarcely imagine at present.
There is something wrong with the audio and once you notice it, it's really annoying. Clicking mouth noises are way too strong I think...
Adam Pitas Guthrie I tho
Adam Pitas I thought that was a mouse clicking
I'm sure the narrator is licking the microphone
mics a bit close to your mouth dont ya think.
I was looking for this comment
I don't think the American and OPEC oligarchs will take to kindly to their petrodollar being threatened..
@1:37 - @1:42 the illustration is incorrect. the arrow for the flow of ions should be right to left (not left to right). obviously you've got several people working on these videos, and they cant all be expected to know the science! you should employ me to fact check :0 :)
Sorry, you are wrong here - the zinc +ve ions flow from the zinc anode, through the electrolyte towards the copper cathode. Of course the -ve ions in the electrolyte will flow from right to left, but the voice over says "movement of metal ions through the solution" and these flow in the direction of the arrow.
also 2:50 methane being converted to CO2 is not adding to the greenhouse effect. methane is a much stronger greenhouse gas. your videos need a more scientific editor. #me
The methane is natural gas, and is not purposely released into the atmosphere. Using it as a source of hydrogen is not 'green' because it is equivalent to burning the methane in a normal furnace or engine - forming H-O-H and O=C=O, thus releasing new carbon dioxide into the atmosphere.
