Australian National University (ANU) physicists have discovered radical new properties in a nanomaterial which could one day harvest heat in the dark and turn it into electricity. The research team has demonstrated a new artificial material, or metamaterial, that glows in an unusual way when heated. The metamaterial opens new possibilities for highly efficient thermophotovoltaic […]

Scientists at Duke University’s Pratt School of Engineering have designed a power-harvesting device with efficiency similar to that of very best solar panels using inexpensive materials configured and tuned to capture microwave signals. For now the device wirelessly converts the microwave signal to direct current voltage capable of recharging a cell phone battery or other […]
