If cars ran on sea water instead of gasoline, how long till the oceans dry up?

Question

If it were possible to run engines on sea water anyway.

Answer 1

They wouldn't.

Speaking hypothetically one would have to assume that the exhaust from such an engine would just be another form of water (water vapor). This of course would evaporate into the atmosphere and eventually rain back down into the oceans.

Answer 2

The oceans would outlast the autos which would not be able to process all of the elements and organisms in seawater. Kind of like a coffee maker that gets clogged with so much scale from the water.

Fresh water (distilled likely) on the other hand is theorized to never be diminished, as the elements that make up the compound (Hydrogen and Oxygen) would simply be liberated from each other in the process, and would eventually be condensed again in the atmosphere and returned to the earth.

Answer 3

Sorry: you are able to no longer. that's an old legend, complicated via a gadget that looks to artwork yet is definitely some thing of an phantasm. the assorted schemes you have examine all contain putting a bottle of water decrease than the hood and working present day from the battery via it. this would generate a small volume of hydrogen and oxygen gas, that's then allowed to pass for the duration of the engine. however the quantity of hydrogen and oxygen is negligible, it makes a marginally undesirable gas, and whether it did impact the working of the engine the means you get from burning the gases is decrease than the means used to offer them. human beings decide to fool themselves and others, and that i'm afraid that there is extremely some foolishness going around approximately gas-unfastened automobiles purely now.

Answer 4

Never. That water will find its way back into the circulation of the environment one way or another and eventually make its way back into the sea.
