Cars could one day run only on water

I will then be ready to update the engine in my car & add that flux capasitor.

Don't say I didn't warn you about that flux capacitor... they're a real bitch to replace aftermarket!

I took the title in totally the wrong way (as per usual). I thought the OP meant that we would only be able to drive around like this...

 

[Why Not?]

However, I am not suggesting a free lunch as I suggested that more generators on moving parts of a car would produce electricity while going down a slope instead of speeding the car or causing braking force to waste energy by dissipating heat


An efficient capture of energy esp in mountainous regions

While going uphill or on even terrain the computer could disengage the generators or direct it to the required braking force

Cars with such systems have been on the market for over a decade now. The most common one is the Toyota Prius but there are many others. Most totally elctric vehicles such as the Tesla do this.

 

[Why Not?]

....

Less than thirty percent of fuel burned in a car makes it move forward, the rest is heat,.... why does no vehicle have a system to use the heat that is wasted? Boil the water with the engine, let it run a small turbine to make electricity, condense the steam to water and boil it again... it's how a steam engine worked?, Isn't it?... Not the part about electricity, the part about the change of state from steam to water. One gram, ( one cc ) of water gives over 1800 ccs of steam... shouldn't a radiator's job be to convert the steam back to water to be boiled again?

BMW has developed such a system and is testing it now. It will recover heat from the exhaust and use that to supply electricity to the car instead of using a generator. It has not been marketed yet.

 

[Why Not?]

Turning H2O into HHO

requires too much electricity

Will not work

To my knowledge there is no such thing as HHO. HHO is H2O. If you apply electrolysis to water you get H2 molecules and O2 molecules. Compressing the two together would just create a bomb waiting to go off. H2 is highly reactive in the presence of oxygen.

As for it not working that depends. The process of electrolysis is well known and proven. Whether it "works" is a simple question of economics. How cheap is your electricity (or your source of heat to generate electricity) and how much is the hydrogen worth? Any change in either side of this equation could make it "work". Right now, in Iceland they are generating hydrogen through electrolysis from a geothermal heat source and using it to power buses.

Well given that Jesus walked on water, I guess cars could run on water, why not?
