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. This development has a range of advantages, including eliminating the need for clean or filtered water to feed the system – any place that has water vapour in the air can produce fuel.
