Here, the focus is on screw compressors in refrigeration and the use of economizers and side loads to enhance energy efficiency. The advantages of screw compressors over reciprocating compressors are highlighted, particularly their ability to have a secondary suction port for drawing additional vapor. The economizer utilizes this port to sub-cool liquid going from the…

Fundamentals of Vibration Measurement with Screw Compressors
Screw compressors are quite large and always a vibration signature on machines. It’s important to learn what we can from those signatures to know if maintenance is needed or if a machine needs some attention. Starting with the basics today and work up to a little more specific interpretation of screw compressor details.

Small Margins, Big Risks: How Fraud Hurts Texas Energy Retailers
Fraud has quietly become one of the most existential threats in Texas’s deregulated retail electricity market—because the business runs on razor-thin margins and delayed payment. Under the non-POR system overseen by the Electric Reliability Council of Texas (ERCOT), retail energy providers assume the full risk of nonpayment. With profit margins often measured in just a…
From 30 to 1,500 Students: Scaling Mass Experiential Learning with How to Change the World
Higher education is at a crossroads. Institutions are being asked to do more with less—serve more students, prepare them for a rapidly changing, AI-shaped workforce, and prove the real-world value of a degree—all at the same time. Employers consistently note that while graduates are technically capable, many struggle to apply what they’ve learned to…
What the Future Looks Like if We Get It Right

This final episode of the five-part Health and Life Sciences at the Edge series looks ahead to what healthcare could become if patient monitoring gets it right. Intel’s Kaeli Tully is joined by Sudha Yellapantula, Senior Researcher at Medical…
AI Is Forcing a Rethink of Data Center Infrastructure at Every Level
The data center industry is being redefined by AI’s demand for faster, denser, and more scalable infrastructure. According to McKinsey, average rack power densities have more than doubled in just two years. It went from approximately 8 kW to 17 kW, and is expected to hit 30 kW by 2027. Global data center power demand is projected…
