Reversible Thermoelectric Nanomaterials
Physicists Dr. Tammy Humphrey and Dr. Heiner Linke have discovered that a particular structure and configuration of nanowires can have remarkable thermoelectric properties. Meaning that electricity can be generated from heat differentials across materials. Even better, the thermoelectric effect is reversible. This means that the nanomaterial could operate as a heat pump, in essence transferring heat. What does this all mean? There are a few things this can bring to the table - processors that don’t require fans, precise control over temperature for labs and sensors, and refrigeration without pumps or chemicals. They also say it could have significant uses in energy production and transportation such as transferring engine heat to electricity for hybrid vehicles.
