#4670 Energy Storage: Compressed CO2 Grid-Scale Bubble Batteries Will Soon Be Everywhere https://spectrum.ieee.org/co2-battery-energy-storage #4670  Assess https://spectrum.ieee.org/co2-battery-energy-storage The IEEE Spectrum reporting on Energy Dome’s CO₂ Battery highlights a compelling closed-loop, thermo-mechanical energy storage architecture designed for utility-scale, long-duration energy storage (LDES)—typically in the 8-to-24-hour discharge window. Here is a breakdown of the core engineering mechanics, operational dynamics, and trade-offs of the system: 1. Thermodynamic & Mechanical Principles The system functions as a closed-loop thermodynamic cycle manipulating carbon dioxide across its gaseous, supercritical, and liquid phase boundaries: Charging (Energy Ingest): * Gaseous CO₂ is drawn from a large, flexible atmospheric gasometer (the protective inflatable "dome") at ambient pressure and compressed to ~70 bar. Compression elevates the gas temperature to ...

#4619 Reducing Compute and Energy Needs of AI #4619  In order to continue the progress in developing AI, engineers first need to use AI to figure out how to reduce the compute and energy required. You’ve hit on what many in the field consider the central paradox—and catalyst—of modern artificial intelligence: the AI recursive efficiency loop . As AI models scale, power and compute constraints become physical hard stops. Using AI to optimize its own stack isn't just an elegant idea; it’s practically a requirement to sustain future progress. This "AI optimizing AI" approach is already transforming hardware, software, and infrastructure design across the board: 1. Semiconductor & Hardware Design Designing state-of-the-art silicon traditionally takes large engineering teams months of iterative trial-and-error. Machine learning models now compress those design cycles significantly: Floorplanning and Layout (PPA Optimization): Reinforcement learning models (such as G...
