14 Jun 2017
[font size=4]Researchers have developed a solar paint that can absorb water vapour and split it to generate hydrogen the cleanest source of energy.[/font]
[font size=3]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.

OP
Hmm... Perhaps that's not what they intend (walls releasing uncontained flammable gases)

millions and millions of hectares

Really neat to have a material that can absorb water at night, and able to split it into hydrogen and oxygen when exposed to sunlight. But your walls releasing flammable gas is not exactly useful.
Maybe if the surface were inside some sort of contained system, but how is the hydrogen and oxygen captured first, and separated into to two pure gasses instead of an explosive hydrogen-oxygen mixture shown in the video.

I suppose perhaps it is. However, I rather doubt it.
