Solar Paint Converts Moisture From the Air into Energy

Researchers created a solar paint which absorbs the moisture in air and converts it into hydrogen fuel

A team of Australian researchers found a new way to supply homes with energy. They created a solar paint which absorbs the moisture in air and converts it into hydrogen fuel. This fuel can be used to produce energy in a cheap and eco-friendly way.

A special compound absorbs moisture

The research team from RMIT University, Melbourne, developed this solar paint made up of unique components. One of them has a mechanism resembling that of silica gel, which you probably know from electronic or shoe packages. They are little grains put in tiny sachets to absorb the moisture around food or other products and help them preserve well.

However, apart from the absorbent, the solar paint also has synthetic molybdenum sulphide. This compound is a semiconductor, and is able to make the moisture split into oxygen and hydrogen atoms. While they were testing the substances, researchers discovered how to add all of these into a paint.

If you mix the sulphide with several particles of titanium oxide, you get a paint which absorbs sunlight and produces energy. The energy results from hydrogen fuel, which is easily obtained from both moist air and solar energy.

Solar paint is easy to produce and does not require many resources

Titanium oxide is, in fact, white pigment, which is already present in most paints. Therefore, adding those compounds can convert any paint or surface into an energy-producing panel. This method comes with plenty of advantages.

First of all, clean and filtered water is no longer needed to produce energy, since it can be provided by vapors in the air. Also, this solar paint is effective not only in damp areas, but also in drier regions which are closer to sea. Of course, a place doesn’t need to be near an ocean or a sea if there are enough water vapors in the air.

The solar paint is an easy and effective method to produce energy just by using sunlight and water vapor from the air. Researchers hope that the paint will soon be available together with the classic solar panels, as it can be produced at smaller prices and requires less resources.
