  • Nuclear waste storage and environmental intergenerational externalities

    This article analyses the long–term consequences of nuclear waste storage within a general equilibrium framework. The objective is to determine the conditions for which the storage of waste, and thus the transfer of externalities towards the future, can be optimal. These conditions could explain the implementation of intergenerational externalities, justifying an intertemporal Not in My Back Yard ...

  • Rain Gauge Fixed with 12 V Regulator

    A friend came to me with a curious problem regarding the research weather stations he maintains. The Geonor rain gauges were experiencing glitches. Some of his stations exhibited only occasional problems, and others were failing almost daily. In the plot below, the rain gauge output is in blue. It should be a steady, increasing line representing the weight of the accumulated precipitation. ...

  • Controlling methanogenesis and improving power production of microbial fuel cell by lauric acid dosing

    Methanogens compete with anodophiles for substrate and thus reduce the power generation and coulombic efficiency (CE) of the microbial fuel cell (MFC). Performance of a baked clayware membrane MFC inoculated with mixed anaerobic sludge pretreated with lauric acid was investigated in order to enhance power recovery by controlling methanogenesis. In the presence of lauric acid pretreated inoculum, ...

  • Solar tunnel drier with thermal storage for drying of copra

    A natural convection solar tunnel drier integrated with rock bed as sensible heat storage material was developed to test its performance for copra drying. The experiments were carried out with and without the integration of heat storage material. The temperature gradient inside the tunnel drier is about 10–25°C during the clear day and 7–12°C during off–sunshine hours, which is quite sufficient ...

  • Control and small-signal analysis of battery and supercapacitor hybrid energy storage systems

    This paper is devoted to control strategies for an active battery and supercapacitor hybrid energy storage system using the master-slave control scheme, where the charging and discharging currents of the supercapacitor are dependent on that of battery and the current sharing ratio depends upon the load conditions. A small-signal model is proposed, which considers the variations in the currents of ...
