Bielefeld University physicists have found a way called spin currents to use the energy electronic devices such as computers generate as heat that mostly goes to waste. They apply the heat to generate magnetic signals known as ‘spin currents’. In the future, these signals could replace some of the electrical current in electronic components. In […]

A new Washington State University thermoelectric generator device could one day turn the heat generated by a wide array of electronics into a usable fuel source. The device is a multicomponent, multilayered composite material called a van der Waals Schottky diode. It converts heat into electricity up to three times more efficiently than silicon – […]

VTT Technical Research Center of Finland and German company ZAE Bayern have built a pilot system emission-free, solar-powered chiller. Demand and the need for cooling are growing, the potential market is world-wide, particularly in warm countries. VTT and ZAE Bayern have developed a solar-powered 10 kW chiller. This absorption chiller works in the same way […]

Stanford University researchers led by Professor Roger Howe say new material using graphene could reignite the field of thermionic energy conversion, improving the way we produce electricity and reducing the impact the process has on the environment. The concept is based on a satellite-powering technology that was abandoned decades ago that has been reinvented to […]

Ohio State University researchers have figured out how to convert heat into electricity in a form more suitable for industry. This is the research group that pioneered the use of a quantum mechanical effect to convert heat into electricity. The engineers describe in Nature Communications how they used magnetism on a composite of nickel and […]
