Impressive real-world numbers of EDF 🇫🇷 (with its smart charging subsidiary DREEV) for charging a fleet of electric waste collection trucks:
10 MWh of charging for 10 trucks, at a cost of minus €129, by collecting otherwise wasted energy and providing grid support

Abstract: Inspired by cephalopod jet propulsion through compliant funnels, this study investigates elastic wave propagation and energy exchange in passively deforming cylindrical nozzles through three-dimensional, two-way fluid-structure interaction simulations. Flexible nozzles with varying stiffness ($Eh = 75 - 500~\mathrm{N\,m^{-1}}$, where $E$ and $h$ are Young's modulus and nozzle thickness, respectively) are subjected to a pulsatile jet inflow at $Re \sim 4000$. Increasing nozzle flexibility reduces the deformation-wave speed in accordance with Moens-Korteweg scaling, thereby prolonging the nozzle expansion phase. This delayed expansion enhances jet entrainment and elastic energy storage while suppressing early shear-layer roll-up and vortex formation. During contraction, the stored elastic energy is released, thereby enhancing jet acceleration and vortex formation. For the most flexible nozzle, the primary vortex-ring circulation increases by 52.13%, the vortex convection distance by 9.00%, and the peak outlet kinetic energy flux by a factor of 4.62 compared with a rigid nozzle. These effects collectively yield a 61.92% increase in total hydrodynamic impulse. These findings identify passive wave-speed tuning via nozzle compliance as a mechanism to enhance pulsed-jet thrust for bio-inspired underwater propulsion.

Mark Zuckerberg was so convinced the metaverse was the next big thing that he renamed his company after it.
Meta, as Facebook is now known, bet the farm on virtual reality,
investing more than $80bn into metaverse-related ventures over the past five years alone
—only to abruptly decide it wasn’t the future after all.
In March this year it was announced that Horizon Worlds, Meta’s flagship metaverse venture, would shut down its VR operations in June, continuing only as …
