Microscopic water droplets jumping from one surface to another may hold the key to a wide array of more energy efficient products, ranging from large solar panels to compact laptop computers. Duke University engineers have developed a new way of producing thermal diodes to regulate heat by bleeding it away or keeping it in. The method solves several shortcomings of existing devices. While thermal diodes can be made from solid materials, these solid-state diodes are not nearly as...

What happens when electronics overheat? The short answer is: nothing good! In microgravity, natural convection does not occur, which makes cooling equipment a challenge. So how do you keep electronic and computer components from overheating in space? In satellites used for communications, global positioning systems, and defense purposes, a heat pipe is the device used to regulate temperature and keep the overall systems operating reliably. A heat pipe is a simple device that can efficiently...
