Why water engine not used in the automobiles?

So far no way has been found to get energy for motive power from water alone.

You can use water if you'd like - in racing, they actually use water, rather than antifreeze. There are caveats,, though. If you live in a place which experiences freezing temperatures, antifreeze is going to do much more to protect your vehicle.

Also, the problem with water is that it provides no lubrication to the water pump without additives. Antifreeze does lubricate the water pump.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
