Earlier sources: Energy
Energy research and engineering concern how power is produced, stored, delivered, and consumed. Follow solar and nuclear power, fusion, geothermal systems, batteries, electricity grids, and changing power demand.
SYMTRI organizes observations from public sources into a living map. Connections reflect shared subject matter; they do not establish causation or endorse a source.
Open in the map ↗660 classified signals in the fourteen-day window. Recent momentum: steady. These counts include signals awaiting readable evidence.
Earlier sources
Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity. Dates distinguish paper publication, repository creation, model/dataset activity, Hacker News posts, and KEV catalog additions. “First archived” records when SYMTRI first stored the signal.

Designing a buildable optimised stellarator to confine electron–positron plasmas ↗
In this paper, the design of the plasma equilibrium and superconducting coils for the electrons and positrons in an optimised stellarator electrons and positrons in an optimized stellarator (EPOS), experiment is presented. With newly developed stellarator optimisation tools, including single-stage and stochastic optimisation, as well as high-temperature superconductor strain, this work demonstrates that it is possible to achieve key metrics for the buildability and confinement properties of the device. In particular, satisfactory quality of quasisymmetry and stellarator robustness is designed,…

Energy transition and corporate geographic expansion ↗
Accelerating the energy transition is pivotal to achieving sustainable economic development, yet localized environmental policies can profoundly reshape the spatial allocation of corporate capital. The impact of place-based energy transition policies on firms' cross-regional investment remains largely unexplored. Existing studies primarily examine the environmental and economic consequences of such policies, while paying limited attention to their influence on firms' geographic expansion strategies. Using a sample of Chinese A-share listed firms from 2006 to 2022, we examine whether and how th…

Pathways and mechanisms for layer-wise regulation during laser powder bed fusion of horizontal overhang structures ↗
Laser powder bed fusion (LPBF) enables the freeform fabrication of complex metallic components, yet stable support-free forming of horizontal overhang closure structures remains a major challenge because of severe thermal stress accumulation, insufficient transient support, and progressive closure-region instability. Here, we present a mechanism-guided strategy for overcoming this limitation. An octagonal horizontal overhang structure with closure features was designed using AlCoCrFeNi 2.1 high-entropy alloy as a model material. By integrating in-situ visible-light monitoring, Molten-pool Time…

Local electricity price effects of Bitcoin mining in renewable-rich energy systems ↗
Load-shifting is increasingly important in renewable-rich energy systems. Bitcoin mining is often cited as a large, theoretically flexible load. Despite electricity consumption rivaling medium-sized industrial economies, the energy market behavior and impacts of Bitcoin miners remain largely unexplored. We exploit the large-scale relocation of Bitcoin mining to Texas, which became the world's largest mining hub following China's 2021 ban, to estimate its effects on local wholesale electricity prices. Combining a hand-collected dataset on mining facility locations with high-frequency wholesale…

Pulsating heat pipes for sustainable energy systems: Application-specific evidence and conditional design considerations ↗
Effective thermal management is essential to the efficiency, safety, and scalability of sustainable energy systems. Pulsating heat pipes (PHPs) offer compact, passive heat transport through self-excited two-phase motion in wickless channels. Although existing reviews have extensively addressed PHP mechanisms and performance, translating this knowledge into application-specific design guidance remains challenging. This review examines PHP developments across four major domains: space systems, cryogenic cooling, solar energy utilization, and terrestrial applications. It focuses on how thermal, s…

Energy-aware hybrid artificial bee colony and reinforcement learning for multi-objective task scheduling in green cloud–fog industrial IoT systems ↗
Efficient task scheduling in Cloud–Fog computing environments remains a critical challenge in Industrial Internet of Things (IIoT) systems due to the conflicting requirements of energy efficiency, latency reduction, and Quality of Service (QoS) assurance. This paper proposes an Energy-Aware Improved Artificial Bee Colony (EA-IABC) algorithm integrated with a Q-learning-based reinforcement learning (RL) module for multi-objective task scheduling in Green IIoT infrastructures. The proposed method enhances the exploration and exploitation capabilities of the standard Artificial Bee Colony (ABC) a…

Accounting for Nanofilm Contributions in Interfacial Free Energy Calculations Using Classical Density Functional Theory ↗
Abstract Fluid nanofilms play a fundamental role in nanoscale interfacial thermodynamics, yet their interfacial behavior and treatment within classical density functional theory (cDFT) warrant further investigation. We investigate nanofilm interfacial properties using a cDFT framework built upon the perturbed-chain statistical associating fluid theory (PC-SAFT) for both fluid–fluid and fluid–solid interfacial systems. Comparison with molecular simulations shows that the long-standing numerical discrepancies regarding free-standing nanofilms persist in the PC-SAFT functional predictions, suppor…

A Dichotomy of Finite Element Spaces and Its Application to an Energy-Conservative Scheme for the Regularized Long Wave Equation ↗
Abstract. Certain energy-conservative Galerkin discretizations for nonlinear dispersive wave equations have revealed an unusual convergence behavior: optimal convergence is attained when continuous Lagrange finite element spaces of odd polynomial degree are employed, whereas the use of even-degree polynomials leads to reduced convergence rate. The present work demonstrates that this behavior is intrinsic to the structure of the finite element spaces themselves. In particular, it is shown to be closely connected to the standard [Formula: see text]-projection of derivatives, which possesses a su…

On local and non-local energy transfers in Hall magnetohydrodynamic turbulence ↗
A systematic study of inertial energy cascade in three-dimensional incompressible Hall magnetohydrodynamic turbulence is conducted to investigate the locality of energy conserving triads and the subsequent transfers.

How to assess evidence about Energy
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
