Purdue University researchers with an international team of collaborators have used a ‘thermal metamaterial’ to control the emission of radiation at high temperatures. The advance that could bring about devices able to efficiently harvest waste heat from power plants and factories. Generally, its known that about 50 to 60 percent of the energy generated in […]

Recovery and harvest of heat is the conservationist’s best route to reduce energy consumption.  The amounts of energy that escape use via heat is a stunning number and the heat available from solar and geothermal are huge resources.  When a new technology shows up, even if it’s at the first bright idea stage, we want […]
