Researchers at RMIT University in Melbourne(Australia) have developed an innovative solar paint that produces endless clean energy from water vapour. This revolutionary paint takes up moisture from the air and splits into oxygen and hydrogen. This hydrogen emitted is captured as energy.
The paint combines the titanium oxide, a white pigment used in many wall paints with a new compound called synthetic molybdenum-sulphide. This molybdenum-sulphide acts like a silica gel, helping in absorbing moisture and keep the things fresh and dry. Synthetic molybdenum-sulphide acts as a semi-conductor and also catalysis the splitting of water molecules into hydrogen and oxygen. As a result, hydrogen is captured as a fuel source.
A simple addition of new material to titanium oxide converts a wall into energy harvesting and fuel producing wall.
Researchers who worked on solar paint:
Lead researcher Dr Torben Daeneke, from RMIT University, said: “We found that mixing the compound with titanium oxide particles leads to a sunlight-absorbing paint that produces hydrogen fuel”. Another lead researcher, Distinguished Professor Kourosh Kalantar-zadeh, said “hydrogen – the cleanest source of energy could be used in fuel cells”.

Towards Future-solar paint:
Although, this paint wouldn’t be available commercially for few years. This paint is effective in a variety of climates from very dry to a very damp environment.
Solar power is not only a way to help save environment but also an economic investment. With Cityrene homes which uses solar and air from water technology you can save approximately 5 lakhs within 5 years. As a result, you can save 1 lakh per year with all the other added advantages.
Isn’t this a huge money to save? Click this to know about our completed projects.When this kind of new and eco-friendly technologies makes their way to customers, it will move the world to the future of green and sustainability.
