Did you put the original video or just your copy?

Thank you so much! :))))

Me too buddy, its excellent and he is very good at keeping you interested

There are videos on KZfaq showing Hydrogen delivered via a plug in cartridge or a paste. Both of those methods would significantly improve the distribution process, as well as speeding up refueling (pull out the old cartridge, slide in a new one, and off you go). I could imagine said cartridges being sold in virtually any store.

@@toddprickett6376 There are production and scaling issues, but please notify us when those things become CHEAPER than PLUGGING into a wall outlet like they do in a BEV , Hydrogen = " Fuel of the Future" , maybe another hundred years?

Normal que inspires a los demás, tus videos son increíbles ❤️

There is a pretty great solution out there: Battery electric vehicles, you should give it a try.

yes, maybe an idea is to capture CO2 and combine it with H20 to produce bio fuells. Something like a Sabatier reactor, that can produce methane (CH4). If we can use solar or volcanic heat for the gas making reactor (or electric heat by wind or solar energy) wouldn't that be a great way to a CO2 neutral society?

They should add a smell to hydrogen, just like with propane or natural gas. Like that, we would know faster if there is a leak.

Hydrogen production by electrolysis is about 75% efficient. Hydrogen fuel cells are 40 to 60% efficient. Traditionally electrical motors are about 80%. Now if we are very generous and assume that all the components in the chain hit very high efficiency such as 80% for the electrolysis, 60% for the Fuel cell, and 90% for the motor (because someone will claim that) you get a combined efficiency of 43%. But if we de-rate the motor to 80% efficiency that turns into 38%. With more realistic and reproduceable numbers you get 75% x 50% x 80% and the efficiency is about 30%. Now if you were to include the generation of the electricity to drive the electrolysis then efficiency goes down drastically. But without doing that you can compare the hydrogen fuel cell technology with battery electric vehicles. When I looked for Lithium Ion battery charging efficiency the first answer I got was that it is ner 100% efficient, compared to lead acid batteries that are "only" 85% efficient when charging. Second link claims 99% efficiency while the third ling says it's 70%. The rest I saw claimed between 80 to 90 % efficiency when charging. Even if they are "only" 70% efficient that would still mean that a BEV has an efficiency of about 56% if the motor is 80% efficient. That is a whole lot more efficient than the fuel cell version. Another interesting thing is to look at range. One of the things that people often say is that with a hydrogen driven car you can just fill up the tank in seconds or minutes rather than have to wait for a battery pack to charge. And that's fair. But how far can you go between the fuel stops? And here hydrogen is at a disadvantage as the gas is so light. Even at a liquid state it has only about 20% of the energy density of gasoline when compared by volume. Number ripped from my far from reliable memory so take that with a grain of salt. That means the fuel tank has to be four to five times as large as the gas tank if you want to drive as far on a tank as you do on gasoline. And the tanks can't be simple constructions either. They are either high pressure tanks or they are low pressure isolated tanks. The later is most common in the tests I've seen, but they have the disadvantage that they can't perfectly isolate the hydrogen, so they are constantly bleeding hydrogen that cook off. A tank like that is likely to bleed off all hydrogen in a week or two even if the car never leaves the parking lot. Also the hydrogen that is bled off is a fire and explosion hazzard. High pressure tanks are heavy and expensive. How heavy I can't say as I haven't looked into it. But the fact that auto makers experimenting with hydrogen fuel cells usually don't use them suggests that they are not trivial to build right. Someone I talked to thought that solid hydrogen would be the solution. That is hydrogen chilled down to the degree or pressurized enough that it turns metallic. I did look into that, ignoring all the practical problems of actually doing this. And the results were not encouraging. Metallic hydrogen is not significantly more dense than liquid hydrogen. So it would be a lot of added complexity and cost for very little, if any, improvement in storage density.

@@blahorgaslisk7763 I'm sorry I didn't read everything but you need to include gas compression/liquefaction and transportation Wich will reduce the efficiency significantly. I've worked with hydrogen (liquid and gas) and the tanks are so heavy in comparation to the mass of hydrogen that we usually say things like "the steel truc is here". For the solid state storage it's an utopia, it is indeed possible to store a lot of hydrogen in magnesium for exemple 30% in mass approximately (you need about 1kg per 100km of hydrogen) so the storage could be only 20kg of magnesium for a good autonomy. Buuuuut we need to heat up A LOT the magnesium to recover the hydrogen which is... Not efficient at all...

@@oneilgoisot9615 Thanks for the heads up on compression. It's easy to forget a step like that when you don't work with the media. Enginering Explained did some videos on Hydrogen and talked about the low power per volume you got with hydrogen. That and the heavy tanks for liquid hydrogen was what he concentrated on before even talking about the efficiency. If you want to see some really horrible numbers look at combustion engines running on hydrogen...

@@blahorgaslisk7763 I'll check engineering explained, I also recommend engineering with rosie

fuel cell and electrolysis are also highly susceptible to corrosion ! the efficiency of a gasoline combustion engine ranges between ( 36 % - 42 % ) and perhaps more, this is more efficient than photovoltaic cells ( 18 % - 26 % ), for example.

My chemistry knowledge might not be totally right 🧐 Chat GBT didn't help enough hahaha. Anyway I didn't what to say is consumed, what I wanted to day is that is making the water more conductive.

@@ELECTRONOOBS fair enough. I think at some point you say the electrolysis of sodium hydroxide (which you more or less described), while this is just electrolysis of water. ChatGPT also answers if you make a minor error in the way you ask the question... 😬

yes possible, same as with pure oxygen.

The efficiency goes up running pure oxygen because you’re not having to compress the air plus the power ratios would be higher because oxygen is Five times more powerful than air as an oxidizer

By the way I am using Arduino nano is that causing me problems

So cool :)

Where do you live to find hydrogen stations for longer roadtrips? How often did you change the air-filters during that time? How about the fuel-cell core? How much did you spend on propulsion-system related maintainence?

@@Makatea i live in California. California which is very large. I have done a 730 mile trip in 11 hours with it. Therr has been 0 maintenance on the fuel cell. I have replaced the tires at 50,000 miles and I have replaced the IEE (ion exchange element) twice (the IEE is a consumable that protects the fuel cell and the price of that consumable is around 1.5 cents per mile.

@@homomorphic Thanks a lot for the prompt, detailed answer. What car-model do you have and what motivated you to prefer it over a BEV?

@@Makatea I have a 2016 Toyota Mirai. I have always had BEVs as well (I currentlt have a polestar 2). The Mirai is much better for trips over 150 miles because it recharges in less than 5 minutes. So I drive the Mirai on longer trips and use the polestar 2 for most local driving.

Lo publicaré pero aun no está listo

energy density in same range or more than lead-acid battery, about 80Wh/kg, a bit less then li-ion (which are up to about 200Wh/kg now)

easier containment than hydrogen, same as lead-acid batteries

no harshly toxic stuff, just salts

kinda same as mild sulfuric acid electrolyte

try baking soda instead of KOH/NaOH

You can patent stuff that doesn't work, and in this case it doesn't.

Check his Wikipedia page.

No, it's not. It's mind-boggingly inefficient and can't even remotely compete with battery-electric vehicles. You hear so much about it anyway, because the hydrogen is produced from fossile fuel, so the oil industry has PR-agencies on the job...

@hello the real reason because I don't buy an ev is that little bit too expensive, I would myself use a short range ev,and when is the time for me to change car I'm sure I'll move to ev, is not the way to convince everyone, the range is the only real, and over perceived downside of an ev for everybody,I speak about my colleagues that are hard petrol head, if there are no excuses for them not to chose an ev we can speak of a car for everyone. We need to see the other side of the argument and understand

@@matteoricci9129 in Belgium there is something called capacity tax. In short, they punish people with taxes if they consume too much energy from the grid, because otherwise they have to invest in the electricity grid... So at this moment maybe a hydrogen operated vehicle will be cheaper then driving an electric one (?). In fact that is even an argument to go for a hybrid car... and if all people in Belgium would drive electric cars at this moment, the electricity grid would go down, they warn.

@@pieterpauwelbeelaerts5995 fancy that, in Italy, there was something like that but to improve use of heat pump they removed this tariff for houses, I checked the annual uses of electricity and in Italy is in decline, maybe a 5% over 10 years, so Italian electric grid would be able to cope at least for the first 4 or 5 years of adoption. Hydrogen still uses more electricity than just charging a car, so it will only increase the amount of electricity needed, I don't see it as a solution. Hybrid is a good step in the right direction, and it was a good choice when there are no other alternatives, but you can consider that electric cars are a better step in the right direction, better still no car at all. everybody willing to do these steps will do it depending on his condition, but here we need to check the claims, like what amount of hybrid: - mild (regen breaking and slow speed) is just an ice car that uses less petrol, long therm is not going to solve anything. -plug in could be great, if you use them right.

Except you can end up with chlorine gas byproducts to deal with.

Chlorine is worst

@@AirzonesBlasters very good point! a well ventilated place is indeed necessary. still, given the amounts at play, I would say it's safe enough and easier to open a window than manipulating caustic soda, which involves proper use and disposal of PPE. NaOH just loves sweat and soft tissue.

😊😊😊😊😊😊😊😊

Your point about safety is mostly unwarranted, it's like saying that electric vehicles run on the same electricity used in electric chairs. Tech has come a long way since hindenburg...

If we always talk about inefficiency, we will never progress like today

Not saying is the best but it could be if we invest time and energy into it, in few years it could get better.

@@ELECTRONOOBS true

Punta Arenas: xD

Elaborate.

@@tomclanys Hydrogen is separated from fossil fuels and shipped around the world as ammonia. It does not come from water and electrolysis. This would be dumb to waste so much electricity to, in the end use electricity.

Hydrogen can be obtained in different ways, as it tends to bond with other elements. The most efficient way to this day to get it is by chemical reactions

@@hyundaiverna You can also get it from aluminum foil and drain cleaner. Doesn't mean it works commercially.

Maybe just change the root to your root instead of P:/ etc.... Place your root of the folder?

@@ELECTRONOOBS I just did it and it didn’t work it still says no file or difectory

@@ELECTRONOOBS can you try and follow your tutorial on the code and tell me if you get that issue? And then if you do then you can fix it and tell me please and thank you I’m really annoyed with this because I already have all the stuff solderef

@@ELECTRONOOBS I got past it but another problem went up and then another after that one please try and fix it so that I can finish making this thanks
