Water powered vehicles - possibly feasible?

1.Water is used to generate electricity through a hydro generator/water turbine.
2.The generated electricity is used in an electrolysis process to split water (or another hydrogen-containing substance) into hydrogen and oxygen gases.
3.The produced hydrogen gas is collected, compressed, and stored in high-pressure tanks within the vehicle.
4.The stored hydrogen gas is injected into the combustion engine, where it is ignited to power the vehicle.

potential drawbacks:
>Significant water storage space
Not a huge issue; most vehicles would have large enough space to store several gallons of water, and it would scale with size ofc (smaller car, smaller water tank)
>efficiency of hydro generator and electrolysis process to make it practical
This is more key but since cars can store several hundred gallons of water (see the size of 200 gallon water tank), it remains a matter of actually testing the system out to assess efficiency needs. (electrolysis process should be fine judging from how efficient it is based on already existing tech (70-80% efficiency in submarines etc), and mainly the initial water to electricity generation process via hydro-generator could be a concern for potential bottlenecks)

I'd like some critique on this please.

    but seriously whats the point in storing it when you can just pipe the compressed hydrogen straight into a combustion chamber and make a hydrogen jet car

    This, midwits don't understand the most basic concepts of energy, fuel, and energy density. Oil is a miracle substance because of it's insanely high energy density paired with it's super easy to transport and use nature. Nothing can compete on a physics/chemistry level nor on an economics of scale level. When you need super dense energy to power a excavation machine or fly a jumbo jet nothing gives you more energy gram for gram than oil. It's just not going to happen.

    That's why all the EV's and water cars and all that bullshit is dead on arrival. It's all fruit of a poison tree you will never be able to eat. To defeat oil as a source of energy you need to have a portable fuel that is MORE energy dense than oil and MORE available than oil and LESS expensive to capture, process, and deliver. It's basic science and basic economics. Until you find this magic fuel you will never out compete oil.

    https://en.wikipedia.org/wiki/Energy_density

    Same goes for green energy. Once you factor in all the mining, production, shipping of wind turbines across countries, destruction of wild land, and E-waste the green energy costs you more per Mw hour than oil/coal.

      I guess you could park and fill up on water and then run your h2 generator and if it’s faster and uses less electricity than an electric car then great.

    >Hydrogen
    Hydrogen is one of the most difficult to store materials because of how much pressure it needs and how easily it diffuses.

    If you have access to renewable energy and want to create fuel out of air and water, there are a variety of other energy carriers you can create that are easier to store, like synthetic Methanol or Nitrogen based fuels. Heck, even metal powders would be better and can be endlessly recycled. Liquids and solids are always less of a pain in the ass than gas.

      Indeed, it seems the objective of the hho water guys patents. Basically do the equivalent of a trampoline double bounce of its stretching vibrational modes (well deca bouncing in his patent [ i'll attest the pyramid builders did 28 double bounces)

      get the hydrogen further away, may spice things up with some solvated electron stuff (flush those lone pairs out of the solution, expose mono atomic hydrogen even more (the queens pyramid was found full of salt after all)

      get that hydrogen far enough away, maybe have a small seed stream of h2 gas, have it start reccombining, get that langmuir torch

      tell me again why i should continue script kiddiing when i could move close to a future hydrogen plant (oh look https://en.wikipedia.org/wiki/Atomic_hydrogen_welding it fell out of favour due to low cost alternatives, i wonder what that plant will do to prices,

    Why not use Hydrogen Peroxide instead of Hydrogen. It's a liquid, easy to store and can be made out of water as well. Early rockets used it as a fuel.

      >Hydrogen peroxide is an oxidizer that can help the fuel burn more completely and efficiently, leading to increased power and mileage. It can also help clean the engine and exhaust system, making them run more smoothly. However, if you put hydrogen peroxide in your gas tank, it can cause irreversible damage to the engine's metal and plastic components, leading to rust or corrosion. If you put regular hydrogen peroxide in the gas tank, the engine will not start.
      Well at least you try give example. The product have no emissions.

        I wasn't talking about using a normal combustion engine. When hydrogen peroxide comes into contact with a catalyst it turns into hot steam, so you'd need a steam engine or turbine. Obviously the parts would be made out of corrosion resistant material.

            There are plenty of modern iterations of steam engines around.
            >A literally jet for passenger car?
            Not jet engines, the kind of turbine you'd use in a power plant to generate power, but smaller.

            Also keep in mind with hydrogen peroxide you don't need a boiler or any other thing you'd need with a traditional steam engine, you just spray the hydrogen peroxide on metal catalyst and it reacts immediately turning into hot steam which expands and drives the engine. It's just another working fluid, but uses the same principle.
