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 […]






University of Houston researchers are reporting that they have demonstrated a step forward in converting waste heat – from industrial smokestacks, power generating plants or even automobile tailpipes – into electricity. With energy conservation expected to play a growing role in managing global demand, materials and methods that make better use of existing sources of […]






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 […]
