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 […]

A team of researchers from Vanderbilt University and Oak Ridge National Laboratory (ORNL) has reported a discovery of an entirely new form of crystalline order that simultaneously exhibits both crystal and polycrystalline properties. The newly found crystalline order is being described as “interlaced crystals”. The interlaced crystal arrangement has properties that make it ideal for […]

A multidisciplinary engineering team at University of California San Diego Jacobs School of Engineering (UCSD) has developed a new nanoparticle-based material designed to absorb and convert to heat more than 90% of the sunlight it captures. The new material can also withstand temperatures greater than 700º C (1292º F) and survive many years outdoors in […]

Researchers at MIT and Stanford University have found a new alternative for low-temperature waste-heat conversion into electricity. The conditions needed are where temperature differences exist at less than 100º C (180ºF). Vast amounts of excess heat are generated by industrial processes and by electric power plants simply to be lost into the atmosphere and out […]

Northwestern University (NU) scientists have discovered a surprising material that is the best in the world at converting waste heat to useful electricity. An interdisciplinary team led by inorganic chemist Mercouri G. Kanatzidis found the crystal form of the chemical compound tin selenide conducts heat so poorly through its lattice structure that it is the […]
