Solar paint splits water vapor into hydrogen and oxygen

    Solar paint offers endless energy from water vapour

    Researchers have developed a solar paint that can absorb water vapour and split it to generate hydrogen – the cleanest source of energy.

    The paint contains a newly developed compound that acts like silica gel, which is used in sachets to absorb moisture and keep food, medicines and electronics fresh and dry.

    But unlike silica gel, the new material, synthetic molybdenum-sulphide, also acts as a semi-conductor and catalyses the splitting of water atoms into hydrogen and oxygen.

    RMIT lead researcher Dr Torben Daeneke said: “We found that mixing the compound with titanium oxide particles leads to a sunlight-absorbing paint that produces hydrogen fuel from solar energy and moist air.



    “Titanium oxide is the white pigment that is already commonly used in wall paint, meaning that the simple addition of the new material can convert a brick wall into energy harvesting and fuel production real estate.

    “Our new development has a big range of advantages,” he said. “There’s no need for clean or filtered water to feed the system. Any place that has water vapour in the air, even remote areas far from water, can produce fuel.”
  2. That's a cool invention. Hopefully it also comes with a kit to handle the generated hydrogen safely, because otherwise we'd be looking at a The Martian situation.

    Could take graffiti to a whole new level...

  4. That is one terrifying mental image. :wtf:

    Just a matter of time before they invent a paint that produces electricity.
