New Ways to Turn Waste Heat into Electricity
Researchers at Penn State have developed a practical way to harness the energy from curved, hot surfaces and convert it to electricity. Devices known as thermoelectric generators have been around for some time. They use silicon and other compounds to convert heat into a small electric current. These devices have been mounted onto rigid metal […]
Immersion Cooling Technology Gaining Ground in Data Centers
Cooling of data centers is one of the US Department of Energy’s challenges and poses a real challenge for HVAC design engineers. Traditionally, this has been done by blowing large volumes of cold air through the building. Directing the air through the racks to pass over cooling fins to dedicated return air aisles behind the […]
