Researchers have designed a traveling-wave engine that converts 18% of heat source energy into electricity, outperforming current thermoelectric devices. The device's high reliability and efficient energy conversion make it suitable for deep space probes.
Penn State's new thermoacoustic chiller uses helium gas to keep ice cream in delicious condition without damaging the atmosphere. The technology has potential for widespread use in applications where chemical refrigeration is difficult or banned due to global warming.
Researchers at Penn State have developed a small 'thermoacoustic refrigerator' that uses sound energy to generate cooling, potentially replacing chemical refrigerants. The device operates near resonance frequencies and achieves efficiencies as high as 89% without lubricants or sliding seals.
Researchers at Penn State have developed a compact freezer case using sound waves to substitute chemical refrigerants, reducing greenhouse gas emissions. The Navy has funded the project and is exploring its potential for distributed cooling systems on carriers.
A team of researchers at Penn State has developed a compact chiller that uses sound waves to cool ice cream, achieving temperatures below freezing point with minimal energy consumption. The innovative system, powered by high-amplitude sound energy, has the potential to revolutionize the way we produce and consume refrigerated foods.
