Wax tiles Markedly Cut Energy use for Heating and Cooling
UCSB's adaptive roof tiles are actuated by the phase changes of wax, and can passively stabilize room temperature to radically reduce the energy cost of heating and coolingUC Santa BarbaraBy employing a temperature-sensitive "wax motor," scientists have developed a dynamic roofing tile system that maintains a comfortable room temperature of 18 °C (65 °F)....
