Right now Ammonia is the front-runner as a carrier for Hydrogen for future fuel-cell vehicles, so the "Powerpaste" really needs to be measured up against it as they perform the same function as Hydrogen carriers. The problem with it is that the reaction to produce Hydrogen from Ammonia doesn't completely convert all the input Ammonia, and is thus very wasteful. Also the unconverted Ammonia is itself a pollutant and will thus need to be scrubbed. If a process is found to convert close to 100% of the Ammonia then it will definitely be the carrier of choice as the only output will be Nitrogen (70% of air) and Hydrogen (which is then reacted in the fuel cell to form water.). You can't factor in the price of Magnesium Hydroxide in your equation, because there is only a limited use for it in producing medicine and as a food additive. It's expensive because of the low production numbers. If it available as a by-product in huge quantities (imagine amount of depleted powerpaste cartridges that will need to be scooped out if every car uses one or two cartridges each week.), its price will crash and uses for it will be saturated, especially if it can't easily be recycled back into powerpaste. We're not even counting the cost of collecting, cleaning and transporting it. Compare that with Ammonia where the Nitrogen and water by-products can simply be released straight into the atmosphere from the vehicles (assuming 100% conversion or remaining Ammonia is scrubbed), and the Green Ammonia production plant can simply draw in air and water, add electricity generated by renewable sources, and complete the cycle. (Again assuming they can perfect the process). No return of by-product material is required except for maybe the Ammonia scrubbed during the process.
I like the ammonia solution also. Nitrogen is a great catalyst to "dirty up" the hydrogen, unlike Co2 it is not considered harmful to the environment considering the atmosphere is 80% nitrogen already. I read that Australia was going to employ this solution to incorporate solar energy into the grid. Exporting energy also becomes feasible for hydrogen producers.
Once Thorium reactors come online and they will, the ability to produce the paste will become a non problem. They operate at 600 -700 C Which would mean that they could easily produce the heat needed and power needed to produce the paste almost as a side effect. So Thorium for power grid and thorium to produce the past for the transportation sector. As for back up power for homes and hospitals again something very easily achievable .
Can you imagine how many millions of men must be crazy in love with this fantastically intelligent woman? She is by no means perfect, because nobody is, but what if all women were even half as smart as her? How great would that be a world to live in?
Man. How many hoops are they going to go through to get to a hydrogen economy? Sorry, I'm a business major. I studied alternative fuels and their probability into entering the marketplace. There was a company called Stuart Energy from Canada about 20 years ago that originally made small hydrogen generators for labs. But then they got really ambitious and imagined scaling their process up to create hydrogen vehicle fueling stations. With the help of the Canadian government they produced a demonstration fleet of hydrogen powered busses that were fueled by their "Hydrogen Appliance" from tap water. They put the tap water through a demineralizing process, but it didn't need to be distilled water. I thought they were on to something, but they were bought by a company called Hydrogenics of Canada around 2005 and I haven't heard much about anything going on with the company since. The big problem with hydrogen is that advancements are happening much slower when compared to EVs. When affordable EVs were truly introduced into the market with the Nissan, Leaf ranges were low because battery energy density was low and cost of the vehicles were high mainly due to the cost of the batteries being high. However, these were the only hurdles keeping EVs from taking over the transportation sector. Fuel distribution already existed in the electrical grid we use to run our appliances. Now that batteries have come down in price and keep dropping, and electric car prices are getting more and more affordable, while ranges have passed 200 miles as the base, the invisible hand of economics is persuading a lot of people to buy EVs. EVs are much cleaner than petrofuel cars and the grid keeps getting cleaner making them cleaner even as the vehicles themselves get older. In my educated view, EVs win because battery cars have ranges that are now comparable to gasoline cars, they charge at home which can't be more convenient and give you the full range of the battery every morning, their prices have come down to be closer to the prices of gasoline cars, the cost of fueling and repair are one tenth or less than that of regular combustion engine cars, they are quiet, contributing far less to noise pollution, there is a long distance DC fast charging station network being built out for them as we speak and one already exists for Tesla's electric vehicles, AND they are much cleaner than gasoline or diesel cars and are getting cleaner as emissions free sources of electricity, like wind and solar are added to the grid. The cleaner bit being the only real reason, mentioned in the above video, for still considering hydrogen and the goop stuff as viable. When comparing EVs to hydrogen vehicles, from a business, management and speculative future investment point of view, there is no comparison. To move to a hydrogen economy we first have to remove the problems with hydrogen, that is production, distribution, storing, compressing, dispensing, and using (the vehicles). Given all the hurdles hydrogen needs to overcome to supplant battery electric vehicles, you come to the same conclusion. Hydrogen is "A Big Pain in the ass" when compared to EVs.
You could reclaim the water coming out of the fuel cell reaction and send that back to the water tank. So you may be able to save even more weight upfront in the amount of water needed to be carried.
Sira, thanks for the sense of delight and discovery you bring to these presentations. You could do a piece on something archaic, like making paper bags, and it would go over well! FR
I can imagine a fuel manifold using ammonia as a temporary storage substance, just because of the binding capacity of nitrogen, which is in the neighborhood of oxygen, but can be stored as liquid methane relatively easily as it's closer to liquid oxygen or nitrogen for liquid storage temperatures and pressures, and temperatures not too severly different than what's needed for computer equipment and people.
i am totally a science-luddite, but it seems to me this is a perfect backup power supply. if a town or city were suddenly plunged into darkness, having a backup generator that used this stuff for medium-term power loss would be great. if it doesn't deteriorate over time then it's perfect for long-term energy storage, which typically means emergency and backup systems which do nothing for long periods of time. i suppose there could be a commercial use in refrigeration, any industry using refrigeration needs a good backup power supply, and i recall diesel is usually the choice - but diesel can expire after a time if not used. if this stuff is more long-term stable, then it may be a good replacement. it looks like it could do the job better and greener, and to refuel you just replace the cylinder of paste. a shipping container could use it as a backup. shipping containers are supposed to be powered by the ship, but if there are mechanical issues you might not know until you open it at the destination (too late). having a built-in generator in the container to take over when the primaries fail could help there, and probably lower insurance costs on refrigerated shipping too.
You included resale value of mg hydroxide in overall cost calculation becuz it has demand now and sells for more. But, at larger scale it would break this demand and cost returns would be negligible
It's how you get funding. You generate some hype by means of marketing and media. Then when you try to attract investment/grants, your attempts will be more successful. That's why nuclear fusion has a periodic surge in hype. It's usually an indication that funding in such research is starting to dry up.
You don't mention the most importaint thing - energy requirement to produce Magnesium from Magnesium hyroxide. These are enormous! Much higher than production of hydrogen by electrolysis of watter.
I read the report form the Hydrogen Congress (a scientific study) back in 1978. It discussed several methods of producing hydrogen. It talked about using extreme heat (3 Mile Island), copying nature with photosynthesis and using catalytic material to generate hydrogen. Magnesium fires can not be put out with water, hydrogen is catalyzed out and adds fuel for burning. It would be interesting if this can be developed as a fuel alternative for vehicles in the near future (before 2035).
I'm not sure why they didn't mention it but at least a partial source of the water that you mix with the paste would be that which exits the fuel cell.
Hey Sira! Great video, very informative, well presented and your humour is Spot On! I have to say you look stunning in Red ❤️ Any plans to make a video on the Ambri battery (liquid metal at very high temperatures) ? To be honest I saw a few videos about it, but I didn’t quite understand how it works and how is it economically viable. Thank you for the great content, keep up the excellent work and hope you reach 1 million subscribers. Cheers from Transylvania!
So instead of spending 20% of my salary to get to work, I would spend 200%! This is brilliant, because now working is completely off the table. If I can't afford to work I do not even need to drive! ACCELERATE!
Interesting information. Regarding 9:19, I hope you're not thinking about using sea water directly, since that would be a plumbing maintenance nightmare.
We have power pasta already! LOL But I don't think we have a power pesto yet... You are adorable and delightfully funny with a great sassy edge! Plus, you are clear and concise and fantastic at conveying information. Keep doing great!
A big problem with hydrogen storage is that it diffuses through the metal and destroys the crystalline lattice thus making it brittle.And you need very high pressure ore very cold temperatures to keep it in liquid state. So that alone is a double bonus for the power paste.
Electrolysis requires a catalyst. Could you please make an episode on the cost of catalysts for electrolysis. Excess solar and wind electricity can be applied to desalination and hydrogen production for iron/steel making, fuel cells and process heat. Thus an episode on catalysts for electrolysis would be great.
Powerpaste is perfect for the marine industry, since you don't have to carry the extra water with you. But I wonder if internal combustion with turbine generators and synthetic fuel might be clean enough for the future.
10:17 Great video! All fuel cell cars also contain a battery, much like a hybrid car. The Mirai contains a 1.6kWh li-ion battery to both get the car going and provide burst energy because the FC has to warm up and doesn't react quickly to the accelerator pedal changes. It also just as important for efficiency gives a place to recover energy as the vehicle slows down since the FC process isn't efficiently reversible.
Great video, with much food for thought. . Hydrogen + fuel cell + lithium battery + electric motor would be a good combination where the need to move heavy loads is limited by the low energy density of batteries. A hydrogen powered fuel cell can charge the battery thus eliminating the range limit of the battery alone. Range would be limited only by the amount of hydrogen in the tank. intermittent solar and wind power woul d be just fine for electrolisis.
Sorry to spoil you on @12:08 , I'm from germany and we have the highest energy prices in the world right now due completely major fails in energy politics.With the new law in place since 2022, the prices for power and gas have risen over 40%, 2€/liter for E10 fuel, 0.50cent per KW power and gas is up wopping 70% in a year so please don't say those politics are good or cheap, this has nothing to do with high energy prices like mainstream media is trying to tell people. You should not only relay on german governmental institutes as sources, because german science is sadly more and more corrupted from politics, because these institutes are 100% state owned and have ex politicians running each supervisory board. Why I know ? Because I used to work for many of them as freelancer
The two main challenges to using hydrogen for large passenger aircraft are storing compressed h2 tanks somewhere in tbe airframe, and adverse consequences of leakage. (maybe a third would be does it have sufficient energy density) Would this hydro-goop be a suitable alternative?
Not sure why we are collectively so up in arms over CO2, it’s plant food, but the delve into possible alternatives is always interesting. If recent news from applied US Navy patents is to believed, mind blowing revisions in our understanding of physics may soon bring all new technology and basically free infinite energy, while killing off the petroleum combustion engine industry. Aside of that, Sira, are you spoken for? Absolutely adorable!
As always very interesting Themes! I dont have to agree with anything but this Channel is really very intersting. Thank you very much! And Sina, i a so proud of you! Youre very competent and you dare to show the World youre grey hair you slowly get! CONGRATS!
Regarding the theory of "sell the magnesium hydroxide for more than you bought the paste"... the problem is that if more people start buying your paste and simultaneously selling the magnesium hydroxide, paste will get more expensive and hydroxide will get cheaper.
Thanks for this! A similar technology that's claiming to be pumpable is Hydrilyte, which is being commercialized by an Australian firm. Looks like they're using mineral oil as their buffer liquid!
Negative energy prices in Germany weren't really negative. The cost of producing electricity just wasn't included in the selling price but rather in the subsidies received by wind and solar power plants.
As an individual person, this would be a lot more exciting for me if they had some kit where I could generate and regenerate the goop myself. Hearing that there may be a nifty fuel available for the owners of special vehicles is interesting but not as exciting a diy energy storage.
Great video. This will solve the problem of having a wide-spread hydrogen gas network, and also requiring fuel cell cars to carry heavy reinforced tanks to hold hydrogen gas at v High pressures. BTW, I read that fuel cells can run on other fuels as well, like propane and LPG. While CO2 is still produced, this is still more efficient than ICE tech, and may be an interim solution while we work towards zero CO2. I believe here in OZ, there are people considering such measures. Keep up the good work!!!
i cannot count the number of times ive seen videos or articles "is this the future!?" the answer is no. No it is not the future. Why? Because never once has a video titled "is this the future" has actually come true. if it was the future, we wouldnt need videos on it, it'd already be happening and becoming the future.
FWIW: An advantage to using hydrogen is that EXISTING internal combustion engine powered vehicles can be converted to burn it, as well as using it in newer fuel cell vehicles.
The major problem with hydrogen is platinum for the fuel cell stack. Can't make it remotely affordable while it requires a significant quantity of one of the most expensive metals to make it work.
I've learned more from you and your videos from each video then I did it any college or university. It's the way you present and articulate the information which allows for easy digestion.
4:56 but you need to replace the battery with powerpaste tank PLUS fuel cell PLUS H2 generator PLUS Watertank. And you will still (probably) need a small battery for intermediate storage and power management. So the overall system is still more complex than just "powerpaste". Still super cool invention, I am not critical of the H2 ecosystem or the paste. EDIT: k, you mentioned all this at the end
Mazda would not agree with your estimation about thermal efficiency... "According to MDPI, gasoline engines have a thermal efficiency of between 30% and 36%, while diesel engines can reach a thermal efficiency of almost 50%". Mazda's Skyactive engines are the closest to those figures
I can see this in emergency backup systems. If the self life is indeed long, one can easily see this used as systems that need to be off the grid and provide power for some time with only maybe some mechanical activation force needed (the initial squeeze until the system can power itself). The need to swap out the cartridge makes it a no-go for any day-to-day use as that would mean you need a completely new infrastructure to distribute the pasta globally. Could also see this in military use as they have the means and infrastructure to support the replacement of the cartridges. This might be ideal backup power source for submarines, planes and drones.
Maybe, but in that case you should be pairing it with internal combustion or gas turbine. It seems like fuel cells are way to expensive to be sitting idle more than 95% of the time.
In Canada we have hydro dams producing excess amounts of electricity holding back huge water reservoirs. Isn’t that the cheapest clean way to produce hydrogen?
There is a major problem with hydroelectric dams. They flood large areas of forest that cause vegetation do die thus causing methane gas. Methane being far worse green house gas than carbon dioxide.
I think you may missed a point, the dams already exist. No methane. Also the problem can be mitigated with new dam construction by clearing the basin, . This won’t happen though due to cost compared to renewables.
good! одно из лучших видео про powerpaste, все понятно и с экономическим обоснованием, очень информативно. Интересно было бы еще увидеть цифры по уменьшению углеродных выбросов при этой технологии. Кстати, я не противник выбросов СО2 Мне больше нравится, что у таких систем больше КПД, динамические характеристики у транспорта лучше и на сколько уменьшается шум!!!

In my educated view, EVs win because battery cars have ranges that are now comparable to gasoline cars, they charge at home which can't be more convenient and give you the full range of the battery every morning, their prices have come down to be closer to the prices of gasoline cars, the cost of fueling and repair are one tenth or less than that of regular combustion engine cars, they are quiet, contributing far less to noise pollution, there is a long distance DC fast charging station network being built out for them as we speak and one already exists for Tesla's electric vehicles, AND they are much cleaner than gasoline or diesel cars and are getting cleaner as emissions free sources of electricity, like wind and solar are added to the grid. The cleaner bit being the only real reason, mentioned in the above video, for still considering hydrogen and the goop stuff as viable.
When comparing EVs to hydrogen vehicles, from a business, management and speculative future investment point of view, there is no comparison. To move to a hydrogen economy we first have to remove the problems with hydrogen, that is production, distribution, storing, compressing, dispensing, and using (the vehicles). Given all the hurdles hydrogen needs to overcome to supplant battery electric vehicles, you come to the same conclusion. Hydrogen is "A Big Pain in the ass" when compared to EVs.
I worked using Ammonia borane,it has a higher hydrogen density actually double hydrogen storage capacity of this also it is much easily available
Boron is very toxic and costly as you would already know...
@@oadka Which chemical is non toxic ,ever bought boron hydride
@@amitkumarpatel8206Clearly, you have some experience inthis area which I don't so let me not say random things. Peace.
If this get this in the ocean i Will very worried XD
You could reclaim the water coming out of the fuel cell reaction and send that back to the water tank. So you may be able to save even more weight upfront in the amount of water needed to be carried.
There would be impurities in the water, its not quite as simple as it sounds.
Always so easy to understand when you explain things. Thank you.
Sira, thanks for the sense of delight and discovery you bring to these presentations. You could do a piece on something archaic, like making paper bags, and it would go over well! FR
been a subscriber since the first video , good to see the channel and sira doing very well😊
I can imagine a fuel manifold using ammonia as a temporary storage substance, just because of the binding capacity of nitrogen, which is in the neighborhood of oxygen, but can be stored as liquid methane relatively easily as it's closer to liquid oxygen or nitrogen for liquid storage temperatures and pressures, and temperatures not too severly different than what's needed for computer equipment and people.
The way that your brain works is amazing, love your content!! We want more, we want more :)
Just found this channel and I love it already one video in.
Your commentaries and your presentation sure keep s me interested, intellectual curiosity and humor great video. Keep coming, thanks.
Very cool. Production quality is higher than expected!
i am totally a science-luddite, but it seems to me this is a perfect backup power supply. if a town or city were suddenly plunged into darkness, having a backup generator that used this stuff for medium-term power loss would be great. if it doesn't deteriorate over time then it's perfect for long-term energy storage, which typically means emergency and backup systems which do nothing for long periods of time.
i suppose there could be a commercial use in refrigeration, any industry using refrigeration needs a good backup power supply, and i recall diesel is usually the choice - but diesel can expire after a time if not used. if this stuff is more long-term stable, then it may be a good replacement. it looks like it could do the job better and greener, and to refuel you just replace the cylinder of paste.
a shipping container could use it as a backup. shipping containers are supposed to be powered by the ship, but if there are mechanical issues you might not know until you open it at the destination (too late). having a built-in generator in the container to take over when the primaries fail could help there, and probably lower insurance costs on refrigerated shipping too.
I absolutely love her sense of humor!
Or make hydrogen-powered generators and use them at Tesla charging stations.
You included resale value of mg hydroxide in overall cost calculation becuz it has demand now and sells for more. But, at larger scale it would break this demand and cost returns would be negligible
Love the channel, great spokeswoman
Every few months there's someone declaring, "new breakthrough in battery technology! This changes everything!" And then you never hear about it again.
It's how you get funding.
You generate some hype by means of marketing and media. Then when you try to attract investment/grants, your attempts will be more successful.
That's why nuclear fusion has a periodic surge in hype. It's usually an indication that funding in such research is starting to dry up.
But there has been progress.
You don't mention the most importaint thing - energy requirement to produce Magnesium from Magnesium hyroxide. These are enormous! Much higher than production of hydrogen by electrolysis of watter.
I read the report form the Hydrogen Congress (a scientific study) back in 1978. It discussed several methods of producing hydrogen. It talked about using extreme heat (3 Mile Island), copying nature with photosynthesis and using catalytic material to generate hydrogen. Magnesium fires can not be put out with water, hydrogen is catalyzed out and adds fuel for burning. It would be interesting if this can be developed as a fuel alternative for vehicles in the near future (before 2035).
What a fantastic presentation! So well done! Please do many many more.
Very good production this week, well done !
This video is 100% pure, unadulterated hype. The energy cost to manufacture the paste far exceeds the amount of energy it can produce.
I'm not sure why they didn't mention it but at least a partial source of the water that you mix with the paste would be that which exits the fuel cell.
my thoughts exactly, seems like that could make up for a lot of the water needed.
Hey Sira!
Great video, very informative, well presented and your humour is Spot On!
I have to say you look stunning in Red ❤️
Any plans to make a video on the Ambri battery (liquid metal at very high temperatures) ?
To be honest I saw a few videos about it, but I didn’t quite understand how it works and how is it economically viable.
Thank you for the great content, keep up the excellent work and hope you reach 1 million subscribers.
Cheers from Transylvania!
So instead of spending 20% of my salary to get to work, I would spend 200%! This is brilliant, because now working is completely off the table. If I can't afford to work I do not even need to drive!
ACCELERATE!
Interesting information. Regarding 9:19, I hope you're not thinking about using sea water directly, since that would be a plumbing maintenance nightmare.
Sira, is there a energy storage angle to application of this material?
We have power pasta already! LOL But I don't think we have a power pesto yet...
You are adorable and delightfully funny with a great sassy edge! Plus, you are clear and concise and fantastic at conveying information. Keep doing great!
A big problem with hydrogen storage is that it diffuses through the metal and destroys the crystalline lattice thus making it brittle.And you need very high pressure ore very cold temperatures to keep it in liquid state. So that alone is a double bonus for the power paste.
Thank you for very professional and valuable presentation.
"power pesto and power pasta", i did not see that coming 🤣
Electrolysis requires a catalyst. Could you please make an episode on the cost of catalysts for electrolysis. Excess solar and wind electricity can be applied to desalination and hydrogen production for iron/steel making, fuel cells and process heat. Thus an episode on catalysts for electrolysis would be great.
Cool! Great explanation.
Your channel's humor is A+.
This has quickly become one of my favorite channels. The subtle humor is top notch, and her accent is very pleasant.
Powerpaste is perfect for the marine industry, since you don't have to carry the extra water with you.
But I wonder if internal combustion with turbine generators and synthetic fuel might be clean enough for the future.
10:17 Great video! All fuel cell cars also contain a battery, much like a hybrid car. The Mirai contains a 1.6kWh li-ion battery to both get the car going and provide burst energy because the FC has to warm up and doesn't react quickly to the accelerator pedal changes. It also just as important for efficiency gives a place to recover energy as the vehicle slows down since the FC process isn't efficiently reversible.
Great video, with much food for thought. . Hydrogen + fuel cell + lithium battery + electric motor would be a good combination where the need to move heavy loads is limited by the low energy density of batteries. A hydrogen powered fuel cell can charge the battery thus eliminating the range limit of the battery alone. Range would be limited only by the amount of hydrogen in the tank. intermittent solar and wind power woul d be just fine for electrolisis.
A Hydrogen tank and Fuelcells were added to a model S and named HESLA. So no range anxieties, you can charge and/or refill the car on the go
Sorry to spoil you on @12:08 , I'm from germany and we have the highest energy prices in the world right now due completely major fails in energy politics.With the new law in place since 2022, the prices for power and gas have risen over 40%, 2€/liter for E10 fuel, 0.50cent per KW power and gas is up wopping 70% in a year so please don't say those politics are good or cheap, this has nothing to do with high energy prices like mainstream media is trying to tell people.
You should not only relay on german governmental institutes as sources, because german science is sadly more and more corrupted from politics, because these institutes are 100% state owned and have ex politicians running each supervisory board.
Why I know ? Because I used to work for many of them as freelancer
The two main challenges to using hydrogen for large passenger aircraft are storing compressed h2 tanks somewhere in tbe airframe, and adverse consequences of leakage. (maybe a third would be does it have sufficient energy density) Would this hydro-goop be a suitable alternative?
your channel is mainly based on energy technology .that's a good thing, considering this decade is for energy transformation
You are great at explaining power production....
This seems like what the first robot blood might look like, one of the final developments before the great robot uprising.
Negative Energy prices are just a result of demand and supply mismatch, which usually does not last long... Just saying..
Not sure why we are collectively
so up in arms over CO2, it’s plant food, but the delve into possible alternatives is always interesting. If recent news from applied US Navy patents is to believed, mind blowing revisions in our understanding of physics may soon bring all new technology and basically free infinite energy, while killing off the petroleum combustion engine industry. Aside of that, Sira, are you spoken for? Absolutely adorable!
Nice one, Sira..! Very impressive!
I love the cheekiness of this
As always very interesting Themes! I dont have to agree with anything but this Channel is really very intersting. Thank you very much! And Sina, i a so proud of you! Youre very competent and you dare to show the World youre grey hair you slowly get! CONGRATS!
Regarding the theory of "sell the magnesium hydroxide for more than you bought the paste"... the problem is that if more people start buying your paste and simultaneously selling the magnesium hydroxide, paste will get more expensive and hydroxide will get cheaper.
Nice video 👌
Thanks for this! A similar technology that's claiming to be pumpable is Hydrilyte, which is being commercialized by an Australian firm. Looks like they're using mineral oil as their buffer liquid!
Thank you. The break down of the technology and research is good. Very good
Negative energy prices in Germany weren't really negative. The cost of producing electricity just wasn't included in the selling price but rather in the subsidies received by wind and solar power plants.
As an individual person, this would be a lot more exciting for me if they had some kit where I could generate and regenerate the goop myself. Hearing that there may be a nifty fuel available for the owners of special vehicles is interesting but not as exciting a diy energy storage.
Hi Sira Happy to see you After a long time
Love the video and information. Less than 3 minutes in, have had 3 commercials.
Great video. This will solve the problem of having a wide-spread hydrogen gas network, and also requiring fuel cell cars to carry heavy reinforced tanks to hold hydrogen gas at v High pressures.
BTW, I read that fuel cells can run on other fuels as well, like propane and LPG. While CO2 is still produced, this is still more efficient than ICE tech, and may be an interim solution while we work towards zero CO2.
I believe here in OZ, there are people considering such measures.
Keep up the good work!!!
i cannot count the number of times ive seen videos or articles "is this the future!?"
the answer is no. No it is not the future. Why? Because never once has a video titled "is this the future" has actually come true. if it was the future, we wouldnt need videos on it, it'd already be happening and becoming the future.
When you joked about Hydrogen dreams and deepened your voice a touch, I got an instant feeling that you can sing really nicely. Just saying ..
FWIW: An advantage to using hydrogen is that EXISTING internal combustion engine powered vehicles can be converted to burn it, as well as using it in newer fuel cell vehicles.
This sounds like the first really alternative to the current metal-hydroxide hydrogen storage systems! Great Video !!!! Keep it real :) o.o/
Isn't ammonia as a storage medium, better?
HHO on demand with diesel engines works too . If done right .
Your delivery of the subject matter is both entertaining and informative. Very cool!
Sweet all round.
Thank you
Hello from PicoRivera
Amazing and very interesting video but I wanted to hear you saying "35 kilograms or 35 liters". 😄
Woww Sir, great to see a video after long time... Absolutely loved this one... Keep em coming...
The major problem with hydrogen is platinum for the fuel cell stack. Can't make it remotely affordable while it requires a significant quantity of one of the most expensive metals to make it work.
I've learned more from you and your videos from each video then I did it any college or university. It's the way you present and articulate the information which allows for easy digestion.
4:56 but you need to replace the battery with powerpaste tank PLUS fuel cell PLUS H2 generator PLUS Watertank.
And you will still (probably) need a small battery for intermediate storage and power management.
So the overall system is still more complex than just "powerpaste". Still super cool invention, I am not critical of the H2 ecosystem or the paste.
EDIT: k, you mentioned all this at the end
Mazda would not agree with your estimation about thermal efficiency... "According to MDPI, gasoline engines have a thermal efficiency of between 30% and 36%, while diesel engines can reach a thermal efficiency of almost 50%". Mazda's Skyactive engines are the closest to those figures
I can see this in emergency backup systems. If the self life is indeed long, one can easily see this used as systems that need to be off the grid and provide power for some time with only maybe some mechanical activation force needed (the initial squeeze until the system can power itself). The need to swap out the cartridge makes it a no-go for any day-to-day use as that would mean you need a completely new infrastructure to distribute the pasta globally.
Could also see this in military use as they have the means and infrastructure to support the replacement of the cartridges.
This might be ideal backup power source for submarines, planes and drones.
Maybe, but in that case you should be pairing it with internal combustion or gas turbine. It seems like fuel cells are way to expensive to be sitting idle more than 95% of the time.
In Canada we have hydro dams producing excess amounts of electricity holding back huge water reservoirs. Isn’t that the cheapest clean way to produce hydrogen?
There is a major problem with hydroelectric dams. They flood large areas of forest that cause vegetation do die thus causing methane gas. Methane being far worse green house gas than carbon dioxide.
I think you may missed a point, the dams already exist. No methane. Also the problem can be mitigated with new dam construction by clearing the basin,
. This won’t happen though due to cost compared to renewables.
good!
одно из лучших видео про powerpaste, все понятно и с экономическим обоснованием, очень информативно. Интересно было бы еще увидеть цифры по уменьшению углеродных выбросов при этой технологии.
Кстати, я не противник выбросов СО2
Мне больше нравится, что у таких систем больше КПД, динамические характеристики у транспорта лучше и на сколько уменьшается шум!!!
