Future ..problem or not?

Question

When cars that run on water are sold..when water is used..something must b its exhaust... its other form of water..right? So that goes in the air, and causes more clouds and rain. would it just rain for almost ever? will we run out of water cuz everyone has it in their cars? will it create the world to heat up because its steam (i think)? is there a limit.. will the atmosphere adapt?

what do u think?

support your answer..im interested

Answer 1

Reducing pollution is fine and I recommend that for many reasons but cars in and of themselves are not creating enough water vapour to make clouds.  The particulates rising into the air may cause dust (hygroscopic nuclei) that super condensed water vapor attaches to.  But the water supply is not diminshed as a result.

Answer 2

While I think water cars are forever a pipe dream I will attempt to answer this one anyway....

Most water motors designs, in theory,  use electrolysis to separate the water molecules.   The result is hydrogen and oxygen which can be burned.   However, when these are burned, there would be no exhaust left over.    These current theoretical designs are flawed due to them involving the concept of a perpetual motion machine which is impossible.

By the time in the future that we could have water cars, I'm sure science will also figure out how to pull water back out of the air without waiting on a storm.   I think we are safe.
