How to repurpose abandoned railway tracks: Two projects explore driverless electric mini-trains
Autonomous rail vehicles with few seats could connect low-demand destinations at a very low cost, although Spanish legislation poses a stumbling block

Zweite Ernte beim #Rhabarber.
Er hat es dieses Jahr nicht ganz so sonnig, weil das #Balkonkraftwerk an der Seite etwas Schatten verursacht. Dadurch bleiben die Stengel anscheinend etwas dünner. Aber sonst ist die

Reverberation Mapping Data of NGC 5548 Imply a Multicomponent Broad-Line Region
Line broadening and variability are observational hallmarks of active galactic nuclei which allow us to measure supermassive black hole masses as well as constrain the geometry and kinematics of the emitting gas, with the most precise measurements requiring a degree of modeling. Two popular models of the broad-line region describe the emitting gas as either a distribution of puffed up clouds or a thin disk with strong velocity gradients. As we show in this work, key features in the reverberatio…

Reusing EV batteries for energy storage can offer greater carbon savings than direct recycling
When electric vehicle (EV) batteries reach the end of their service life, they can be recycled to recover valuable raw materials for the production of new batteries. Alternatively, retired EV batteries can be repurposed for use as stationary energy storage systems, helping to integrate renewable energy into the power grid, manage peak loads, and enhance energy security.
