MARTHA’S VINEYARD, MA — This geothermal rescue was for a closed loop geothermal system that was seriously overheating during the cooling season. This system had ten vertical loops that served 11 heat ...

Scientists from the United Kingdom’s University of Nottingham and China’s Southwest Jiaotong University have developed a novel hydronic closed-loop PV cooling system for hot and arid regions. “We ...

I've been doing a lot of research in preparation for going to a new computer in the next 3-4 months. The last time I built a computer was in 2010, so it's been a while and it seems like a lot has ...

• Maintaining consistent die temperature in the presence of local 1 to 2-mm 2 hot spots with power densities of 500 W/cm 2 or above • Increased system noise due to high-volume air flow • Reduced ...
