Researchers from South Korea have recently discovered how paint can absorb heat well on surfaces.

The thermoelectric paint adopts bismuth telluride and is mixed with other particles. It is heated on a surface for better heat-to-electricity conversion properties. Power generated by the paint can be useful in roofs and walls of homes, and cars and other vessels.

The technology is said to be more advantageous compared to thermoelectric generators, for paint can be spread on surfaces, providing a wider coverage for absorption.

This is good news for the overall paint industry because these kinds of emerging technologies are expected to boost paint sales in various industries. In the US, demand for paint is predicted to jump 3.8 percent through 2019 thanks to recovery in construction and increase in environment-friendly options. Paint is not just made earth-friendly but can also be more energy-efficient soon.
