Next-Gen CEMS: Simplifying Data Center Emissions Tracking
Innovations like laser spectroscopy are simplifying data center emissions monitoring, cutting maintenance burdens for IT-focused engineering teams.
Data centers monitor emissions from their onsite power generation through continuous emissions monitoring systems (CEMS), which measure pollutants like nitrogen oxides, carbon monoxide, and particulate matter to meet regulatory requirements. Traditional CEMS relied on extractive chemical sampling that required frequent maintenance, took up valuable space, and introduced measurement errors, creating particular challenges for data center teams with IT rather than emissions expertise. Modern CEMS use laser spectroscopy technology, which shoots lasers through gas samples to identify pollutants without needing to remove moisture or use failure-prone equipment like chillers and pumps, resulting in more compact systems that require less maintenance and reduce downtime. These advanced systems also provide real-time feedback on combustion efficiency, allowing data centers to optimize fuel burn and reduce emissions while staying compliant with environmental regulations.

Google Unveils TPU 8i Max and TPU 8tx: A Dual-Chip TPU and a Confidential TPU
Google has added two new systems to its eighth-generation TPU lineup. TPU 8i Max targets massive context windows and rack density. TPU 8tx targets secure, confidential inference. Google TPU 8i Max is a dual-chip package built from 2 TPU 8i chips. Both arrive alongside TPU 8t and TPU 8i, announced in April. TL;DR Size: TPU 8i Max = 2 TPU 8i chips in 1 package. TPU 8tx = TPU 8t silicon plus 5th Gen AMD EPYC hosts. Runs on: Google Cloud TPU systems. Performance: 8i Max doubles TPU 8

IBM Announces IBM Quantum Nighthawk r3: A New Processor to Support 10k Quantum Operations on 520 Programmable Qubits
IBM has announced IBM Quantum Nighthawk r3, its next superconducting quantum processor. It is designed to run 10,000 quantum operations accurately across 520 programmable qubits. In 2027, IBM plans to link 2 r3 chips into a single 1,040-qubit system. For developers, the announcement is speed. The current Nighthawk r2 already runs workloads up to 19x faster than IBM’s earlier processors. TL;DR Size: Nighthawk r3: 520 programmable qubits, 2,034 physical qubits, 10 l-couplers. Nightha
Why the data center you dread might never even be built
The data center boom is running into serious real-world obstacles, from widespread local opposition and permitting delays to a scramble for electricity. Before those challenges even come into play, though, there’s a more basic problem: A lot of the projects being announced may never get built in the first place. With billions of dollars in AI infrastructure […]
