THE INTERNET IS THINKING
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 ↗728 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.

The ePESSTO+ census of ZTF nuclear transients. I. What flares in galactic nuclei? ↗
Transients in galactic nuclei arise from distinct processes, only some of which trace the supermassive black hole (SMBH). These include tidal disruption events (TDEs), changing-look active galactic nuclei, Bowen fluorescence flares (BFFs) and ambiguous nuclear transients, alongside supernovae that appear nuclear but are unrelated to the SMBH. Reliable classification requires spectroscopy, which will not scale to the alert volumes of the Legacy Survey of Space and Time (LSST). We aim to characterise the population of nuclear transients, to identify early observables capable of distinguishing SM…

Unequal Coherent Ergotropy at Equal Interferometric Visibility and Energy in Quantum-Controlled Interferometers ↗
The ergotropy, or unitarily extractable work, of a quantum system naturally splits into incoherent and coherent contributions, respectively set by population inversion and coherences in the energy eigenbasis. We show that this split makes the coherent ergotropy of a Mach--Zehnder qubit sensitive to path predictability that the output interference fringes do not reveal. We send the path qubit, prepared as a thermal quantum battery, through two quantum-controlled interferometers built from the same elements, a fixed beam splitter and a beam splitter coherently controlled to be present or absent,…

Controlling writhe in stellarator optimization ↗
The writhe of a closed curve measures its coiling, and for a ribbon along it, writhe is the contribution to the linking number not due to twist. In stellarators, large writhe implies large helical excursion and has previously been either an uncontrolled outcome in optimization, or fixed beforehand by the choice of the coordinate system. We present a simple method to target the underlying writhe of the plasma boundary during optimization. Our method calculates writhe and linking number directly from the underlying elliptical boundary of the stellarator. It therefore does not require any propert…

Interpretable analytical surrogate modeling for building energy prediction via physically informed feature reduction ↗
Accurate prediction of building energy demand is essential for efficient HVAC system design and energy-aware building operation. Although machine learning models can achieve high predictive accuracy, their limited interpretability restricts their practical use in engineering workflows. This study proposes an interpretable analytical surrogate modeling framework that integrates data-driven learning with explicit analytical formulations for building energy prediction. A systematic feature selection strategy combining correlation analysis, mutual information, and physically informed reasoning ide…

Probing Lithium Metal Microstructures with Dynamic Nuclear Polarization from Lithium Metal ↗
Abstract Lithium metal batteries (LMBs) show strong potential for next-generation energy storage, because of their high theoretical energy density. However, their practical deployment is limited by microstructure and dendrite formation, which raises serious safety and efficiency concerns. A key factor influencing dendrite growth is the passivating film, or solid electrolyte interphase (SEI), that forms at the lithium metal surface. Gaining insight into the SEI is essential for controlling dendrite formation, yet this remains challenging due to its complex composition and disorder. Lithium meta…

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.
