Pumped Thermal Energy Storage (PTES) is an increasingly attractive area of research due to its multidimensional advantages over other grid scale electricity storage technologies. This paper built a model and numerically studied the performance Argon based Brayton type PTES system. The was used optimise total work output round-trip efficiency aspect ratio thermal tanks operation packed bed segme...

Indonesia has vast solar energy potential, far more than needed to meet all its requirements without the use of fossil fuels. This remains true after per capita consumption rises match developed countries, and most functions are electrified minimize Because relatively small potential from hydro, wind, biomass, geothermal ocean energy, it will rely mostly on for sustainable needs. Thus, require ...

Local auxin concentration maxima promote organ initiation in the plant shoot meristem, but how auxin peaks are formed has remained unclear. A new study proposes a cellular Matthew effect, where auxin is pumped into those cells that have higher concentrations.
