The U.S. is estimated to lose more than half of the energy it generates – mostly because it escapes as waste heat. Scientists are now developing a new type of system to efficiently capture some of that lost heat. They have designed a surface that enhances low frequency thermal radiation, which is easier than higher […]

Professor Ian Kinloch, Professor of Material Science at the University of Manchester added a small amount of graphene to strontium titanium oxide. The resulting composite thermoelectric material was able to convert heat which would otherwise be lost as waste into an electric current over a broad temperature range, all the way down to room temperature. […]

Researchers at Temple University and the University of Maryland has discovered a new class of magnets that expand their volume when placed in a magnetic field and generate negligible amounts of wasteful heat during energy harvesting. The researchers, Harsh Deep Chopra, professor and chair of mechanical engineering at Temple, and Manfred Wuttig, professor of materials […]

Researchers at Marie Curie-SkÅ‚odowska University, in Lublin, Poland have demonstrated the importance of thermoelectric effects in nanostructures. For about 200 years physicists have sought the efficient turning of heat into electricity in the field called thermoelectrics. Scientists have long known that in conducting materials the flow of energy in the form of heat is also […]

Pacific Northwest National Laboratory (PNNL) research shows heat pump water heaters can reduce an entire home’s energy use if they’re connected to the appropriate ducting. The added ducting improves an already energy-efficient alternative to conventional electric resistance water heaters. PNNL researchers found in their example that a fully ducted a heat pump water heater reduce […]
