A team of researchers from the Royal Melbourne Institute of Technology in Australia has developed a paint that can be used to generate clean energy. Combining the titanium oxide already found in many wall paints with synthetic molybdenum-sulphide, the material absorbs solar energy as well as moisture from the surrounding air. It then splits the water into hydrogen and oxygen, collecting the hydrogen for use in fuel cells. With this product any surface can be turned into an energy harvesting and fuel producing structure - houses, barns, fences, etc..
 
It will take some time before the solar paint is commercially viable, but the researchers expect that eventually it will be inexpensive to produce. Their hope is that it will play a great part in moving humanity away from fossil fuels and towards a future of renewable sources of energy. It is a good example of the increasing number of innovative technologies that are focused on powering homes with clean energy.
