Purdue University scientists have developed an alloy that allows you to get hydrogen and water vapor from water

Actually, oxygen in this reaction is also released, of course, but the most valuable reaction products are exactly hydrogen and water vapor. Hydrogen is understandable because it is a fuel, and water vapor can be condensed, thus obtaining clean water. The alloy obtained by scientists includes metals such as aluminum, indium, gallium and tin. The exact ratios of the metals in the alloy are not reported, and this is understandable - after all, such an alloy is the know-how of the university, and this is quite a commercial development.

Hydrogen can be used in fuel cells, the production of which has recently intensified. Well, and the water vapor formed in the course of the reaction, you can really condense and get drinking water. At the same time, it is not necessary to clean the “primary product”, that is, the source water. In addition, water can be marine, which is even more interesting. Scientists even considered the cost of pure water production.

So, the production of clean water suitable for drinking will cost about 25 cents / liter, and the cost per kilowatt-hour of energy, which will be obtained by utilizing hydrogen, is 35 cents (as far as I know, in New York, one kilowatt-hour of energy costs 26 cents, so really, not so expensive). Yes, besides oxygen, hydrogen and steam, aluminum hydroxide is also formed, which is quite acceptable, since this compound is not toxic / harmful to the environment.

Developers hope that this technology can be applied in poor countries where electricity and clean water are rare. In addition, you can use similar technology on small vessels. It should be noted that the patent application has already been filed, so that in the near future we can expect new devices based on this technology.
