how can we produce water?

Question

we can produce it but not in huge amounts can any one tell a solution

Answer 1

Scientists theorize that most of the universe's water is produced as a byproduct of star formation. Gary Melnick, a scientist at the Harvard-Smithsonian Center for Astrophysics, explains: "For reasons that aren't entirely understood, when stars are born, their birth is accompanied by a strong outward wind of gas and dust. When this outflowing material eventually impacts the surrounding gas, the shock waves that are created compress and heat the gas. The water we observe is quickly produced in this warm dense gas

Answer 2

Water exists in nature in huge quantity and all the living things are produced out of water. It is the greatest sign of the nature on the globe. What a precious gift of God !!! and in what a great quantity !!! Behold, O mankind!

No doubt you can produce water in laboratory too, yet not a huge level because you simple cannot bear the expenses.

Answer 3

bare with my introduction:
we have electrolisis to separate water compound to hydrogen and oxygen to make use of those gaseous, (hydrogen economy).As we have ample of water even in some countries, they have very high humidity, water in the air. http://en.wikipedia.org/wiki/Electrolysis
if i am not mistaken in the same manner it is possible to reverse the process but it is not feasible to produce. better to use desalination process from sea water or trap the water in the air.
and water is also produced as by products for some process.

Answer 4

Many chemical reactions result in water. Burning hydrocarbons for instance.
