Water is the elixir of life. There is life on the earth because of water. Unfortunately it is getting contaminated and scarce. Is it possible to make synthetic water?
Yes, of course you can! It is call Knallgas reaction: combustion and a lot of noise and regularly presented for chemical education in schools.
Creating water this way ...?
But I guess the point is: Removing contamination from water by filtering or destilling requires considerably less energy turnover than electrolysis and subsequent combustion.
And if water is scarce, hydrogen could still be produced by partial oxidation of hydrocarbon. But if enough hydrocarbon is available might it not be advantageous in several aspects to sell the hydrocarbon and to buy "natural" water?
Yes, Knallgas reaction: 2 H2 + O2 → 2 H2O + energy is possible. But can this used for making synthetic water and solve future water woes/wars? Can we make it economically viable?
Very good discussions, I thank everybody involved for extending their respective views. Yes, it is known that synthetic water can be produced in the laboratory, but it seems to me that it may not be economically viable to meet the future demand for all. It would probably be like artificial rainfall or saving life for the dying patient by employing artificial respiration in hospital.
