Can I run my car on water?

Topic starter

I don’t want to pay for gas to use a car now after finding out that it might be possible to drive around by using an hho engine which powers the car with water. I wanted to hear your professional feedback about the subject. Is this all true? Could you make a video explaining what you know and how to install it to have a car fully functional on water via the hho engine?

Snake oil.

You can't run a typical internal combustion engine by splitting water molecules into hydrogen and oxygen that is stored in the vehicle, then recombining them through combustion. It takes more energy from some other source to break the hydrogen-oxygen bonds in the water than you will ever recover in an engine that's recombining them in a combustion reaction. Lots of that energy is wasted as heat. Same with a gasoline or diesel engine -25% of the fuel energy in your gas actually moves the car. The other 75% is unused heat. Theoretically, a motor could run on raw hydrogen gas and only emit H20 in its exhaust, but the only easy way to obtain that is by using catalysts on natural gas, which is predominantly methane, CH4. Electrolyzing water is extremely inefficient because hydrogen and oxygen have very powerful bonds with one another-this is partly why water has extremely high surface tension and it hurts when you do a belly flop in the pool. There are fuel cells that run on hydrogen that you can put in a car, they use these in spacecraft and use the resulting water for cooling equipment and astronauts to use, but those are a ways off to being used in your everyday car.

Are you shilling for those guys? I may have heard more ridiculous things than this but if so it's hard to remember when. What you're talking about is utter and complete nonsense.

The other problem is that if you think you are going to be able to fill up your tank with the garden hose from your house, think again.  The "water" to power these cars will have to be very special and highly filtered and refined, and hence, expensive.

Try it.

Let us know how it goes.

I think here in the United states the fuel will not be one replacement for gasoline.  It will be a combination.  Hydrogen is one way and electric is another. To me the limitations of electricity are cold, and range. Hydrogen its refinement and distribution.  For now. Both will advance but I think hydrogen has the better shot for wider adaptability

Seriously?
