If Everyone started using hydrogen as fuel, and it's only emmission is water, wouldn't that flood the Earth?

Answer 1

If you understand basic chemistry you can not create or destroy matter. You can only change it. There isn't anymore or less water (except for the water that has left the earth on space ships) on earth now than at anytime in the history of the earth

Answer 2

There are not enough "everybody" to make much of an impact. Besides the hydrogen probably would be produced by disassociating water into hydrogen and oxygen so water would be destroyed making the hydrogen fuel.

Answer 3

You've got it backwards. The hydrogen would be burned. Ideally you would pour distilled water into the fuel tank, there would be something to react with the water to decompose it into two parts hydrogen that could be burned as fuel and oxygen would be released, or you could even use the oxygen as fuel as well, but that would be even more difficult to design.

Answer 4

When you consider the global effects of Dihydrogen Monoxide (the main byproduct that is produced as a result of using hydrogen to power cars), it is shocking that scientists and engineers are even considering hydrogen as a fuel. It is criminal. At the very least, unethical and completely irresponsible.

Answer 5

i don't want to go all physics and stuff on ya, but all the water that is on earth is already here, it is just in different forms. it can be what we see as recognizable liquid in some sort, vapor,
or bound with another chemical. it's amazing that some of the
water that we use today has been used before through out history. the cycle never ends.

Answer 6

no you can change the water back to Hydrogen later with electric

Answer 7

The water would be in vapor form

Answer 8

Ever hear of evaporation?

Answer 9

No
