it has something to do with logistics and infrastructure.

you dont build solar cells on cars (atleast not today). you build eletric cars with batteries.
Batteries from today are very expensive and not enviroment friendly and have up to 400 km range.

Hydrogen doesnt need batteries or an electric motor (no need to change the car design) - but you need a lot of energy to split h20 to h.

RESEARCHERS at Princeton University, US, have developed a new way to break down ammonia to make hydrogen, which could lead to the use of ammonia as a hydrogen fuel source.
Ammonia is a low-cost, common material. Research leader and Princeton chemistry professor Paul Chirik explained to The Chemical Engineer that ammonia has a high volumetric energy density and is relatively easy to store, unlike hydrogen. The N-H bond within ammonia is extremely strong, so ammonia has not been widely explored as a potential carrier of hydrogen. Chirik’s team’s new catalyst, however, can break that bond under relatively mild conditions.
Ammonia-metal complexes have been known for more than 100 years, but Chirik says that this is the first time that the physical properties of the bond-weakening that occurs when this happens has been understood. The researchers use a terpyridine bis(phosphine) molybdenum(I) cation, which binds to ammonia. This weakens the N-H bond to the extent that it becomes thermodynamically favourable for one of the H atoms to break away and bind to another H atom, forming H2 gas. The reaction takes place at around 60˚C.
The reaction leaves behind a molybdenum-amido complex – [Mo]-NH2. Chirik says that the complex can be converted back into the original molybdenum-amido complex – [Mo]-NH3 – using strong acids and reductants, for reuse.
“It is a demonstration of a fundamental concept in chemistry and allows chemists to realise after a century of progress, there is much to be learned about ammonia coordination and our understanding of the chemical bond,” said Chirik, adding that any applications are likely to be more in the long-term as the method is a new approach for activating the typically inert N-H bond.
He and the team are currently working on a way to alter the thermodynamics of the reaction to liberate the second and third hydrogen atoms from ammonia. At present, the N-H bond strength of NH2 is too high for that to happen

so how many wind turbines or solar panels needed to make hydrogen.


So all we need to do is find the most powerful solar panels most powerful wind turbines and do the math and work out what energy is needed and if it can be done..
Then we know if it's possible..
Example..It takes 2 turbines producing so many kilo watts to produce so many litres of hydrogen..
I not worked it out YET but some bright spark might be able to do it faster..

Specs below..

Electrolyser: 1 WFuel cell: 500 mWGas storage: 30 cm3 H2;30 cm3 O2Solar module: 2.0V / 350 mAFan: 10 mWH x W x D: 100 x 300 x 150 mmWeight: 6

Electricity needed to power up electrolyzer to produce hydrogen.

When stored as a gas at a pressure of 20MPa:

1 liter contains 0.53kWhEnergy efficiency of electrolysis - roughly 50%. 1.06kWh of electricity to produce 1 liter hydrogen.

When stored as a gas at 24.8MPa1.28kWh = 1 liter hydrogen

When stored as a gas at 30MPa1.50kWh = 1 liter hydrogen

When stored as a liquid at 20K4.72kWh = 1 liter hydrogen

When stored as a metal hydride6.36kWh = 1 liter hydrogen

The amount of energy stored in 1 kilogram of hydrogen.

One gallon of gasoline has about the same energy as one kilogram (1000 grams, which is about 2.2 lbs.) of hydrogen gas. 33.4 kilowatt hours of electricity is equivalent (in energy) to one gallon of gasoline (114,000 BTU); this means 33.4 kilowatt hours is also equivalent (in energy) to one kilogram of hydrogen gas.

After doing my sums you would just use the solar instead of wasting the energy trying to make the hydrogen gas ..YER i am good at math  ..BUT what about this below?..

The crude oil is still over-priced. It is estimated that in Russia and Saudi Arabia, it costs less than $3 to produce a barrel of crude oil. Even if you add the transportation costs and other charges, the total will be a small fraction of the current price.

In any case, in the modern world is the Internet and I think at desire it is possible to promote your working model. So far all I see online is a lie and fraud. I hope someday I will see a real working invention.

Yes maybe you are right, the first person to patent the use of water as fuel to run a car is an american, the second is a Filipino and the third is what the authors posted. They will both suffer the same fate. Oil industry leaders who has big connections on government leaders around the globe will not allow such inventions that is a threat to their business. Such as the faith of the american inventor, also the Filipino inventor from the philippines who sold his water powered car invention to Japan because the government whose being influenced by America did not support his invention. Oil industry will hinder alternative power sources for cars.

Now the world stands at the crossroads. Either oil-producing countries greatly throw off the price of oil that it was not profitable to invest in funding the development of alternative energy, or do they risk to lose the market of oil and gas.

I agree. Existing technology does not allow to reduce the cost of energy. I think that the increase in recent years, the interest of Americans to the development of resources on the moon suggests that again there was a question about cheaper energy costs.

In the early 90s in Ukraine in the city Zaporozhye, a team of scientists invented the technology very cheap heating using water of high pressure pump. Then on the same principle they were created by the car. I even saw how it went. No one wanted to do it and they emigrated to the United States. It seems Americans don't want to do it.

LOL... The boat still needs a power source (either electrical or petroleum) to move. A diesel-powered boat is just like a car. It is converting one form of the energy to another. Water is not used as a fuel here.

I heard that invented the technology of printing solar cells on an inkjet printer. While the production cost is minimal and allows them to do on any surface. And where are these technologies?

I heard that about 4-5 years ago, American students have invented a way as to increase the velocity of the electrons in the battery and achieved a full charging for the mobile phone for 10 seconds. Where is the invention?

do you understand the words "H2O is split into hydrogen and oxygen"?

If its true that is a great invention and i do have my doubts here. has he designed an engine too to run on water .i am all confused here on how the combustion happens

I ask the same question. Already had many charlatans who came in the media to lie.

In 2015 had a Brazilian who claimed to have invented a water-powered car, but later It was discovered that it was a lie when he was asked if he knew that Engine spends much more energy to separate hydrogen atoms than the energy it can generate. he did not answer.

Pretty sure a water-powered car is just called a "boat".
 

Look up superconductors.

"quickly charges and holds a charge" well if you think of it, batteries as a concept are the ones that are getting developed the slowest. Ther isn'y any more efficient way to store energy than todays battery  without increasing it's size.

I hope so too. I am afraid that in fact such development has for a long time, they're just hidden. The oil lobby doesn't want to change the order in the world. And Tesla has to reinvent the wheel.

The first part is a possibility. But I don't think that the second will be realized anytime soon. According to the laws of physics, the amount of energy required to break water in to hydrogen and oxygen is much more than what we get from burning them.

BTW.... Tesla is pumping in billions of USD in to research. Let's hope that they will get the breakthrough soon enough.
