Brick walls can absorb light that creates energy

Researchers at RMIT University (Australia) have developed a solar paint that can absorb steam and dissociate to create hydrogen - the cleanest source of energy.

The paint contains a new compound created as a desiccant used in a desiccant package to keep food, medicine, as well as fresh and dry electronics.

But unlike moisture-proof granules, the new material - a synthetic molybdenum sulfide compound - also acts as a semiconductor, simultaneously separating hydrogen and oxygen from water atoms.

Two scientists from RMIT University are Dr. Torben Daeneke (R) and Professor Kourosh Kalantar-zadeh, working together on this new paint.

Lead researcher at RMIT University, Australia, Dr. Torben Daeneke, said: "We found that mixing the above compound with titanium oxide particles would produce a sunscreen and produce Produce hydrogen fuel from solar and humid air.

Titanium dioxide is a white substance commonly used in wall paint. This means that simple additions in the new material can turn a brick wall into a place to harvest energy and produce fuel for homes. "

"Our new development has many advantages," says Dr Torben Daeneke, "There is no need for clean water or water to maintain and operate the system. Remote areas away from water can also produce fuel. "

Professor Dr. Torben, Kourosh's colleague, said hydrogen is the cleanest and most useful source of fuel in fuel cells as well as conventional combustion boilers as replacements for fossil fuels.

"The system can also be used in very dry but hot climates near the oceans," says Kourosh Kalantar-zadeh, "steam from hot, evaporated seawater that can be absorbed to produce fuel. This is an extraordinary concept - producing fuel from the sun and air in the air. "
