Convertir calor en electricitat

És el que té estar estudiant Química. Et trobes aquest tipus de coses i no te'n pots estar:

HEAT TO VOLTS, ORGANICALLY: Researchers have converted heat directly to electricity by sandwiching organic molecules [blue ring above] between gold surfaces kept at different temperatures. Such thermoelectric converters are typically made from expensive metal alloys, so the result may open the way to cheaper, plastic-like power generators and refrigerators.
