Researchers at the Ulsan National Institute of Science and Technology in South Korea have released a study that focuses on thermoelectric paint.
The study, which was reported upon at Phys.org, looks at converting heat from roofs, exterior walls and other surfaces into electricity. The story says that the paint differs from thermoelectric materials, which are fabricated as chips. They often, therefore, have inexact contact with surfaces from which they are gathering energy. The paint would have far more consistent and complete coverage.
The team published the research in Nature Communications, according to Phys.org. The paint contains bismuth telluride, the particles that are used in conventional thermoelectric materials, the story says.
