Electric Power Generation with Reverse Electrodialysis

The computer simulation program of a practical scale reverse electrodialysis process has been developed based on the program for saline water electrodialysis. The program is applied to compute the performance of an industrial-scale reverse electrodialysis stack (effective membrane area S = 1 m × 1 m = 1 m2, cell pair number N = 300 pairs). The stack operatingconditions are optimized. Seaw...

On Various Geometries Giving a Unified Electric and Gravitational Theory.

1. Recently Einstein' has deduced a unified theory of electric and gravitational fields by forming the Euler equations for the integral of a certain scalar density. I show in the present paper that his new equations can be obtained by direct generalization of the equations of the gravitational field previously given by him. The process of generalization consists in abandoning assumptions of sym...

Electric Power Quality Measurement

The proliferation of non-linear and time-variant loads is causing a number of disturbances on the electric network, from a more and more significant distortion of both currents and voltages, to transient disturbances on the supply voltage. In this respect the electric network behaves as an "healthy carrier" of disturbances, so that a disturbance generated by one customer can be distributed to o...

Electric Power Generating Bicycle

It is manifest the growing interest in both personal health and environmental issues. The device described on this paper contemplates both aspects: generating environment-friendly electric power while keeping fit. A car alternator excited through a 12V battery is coupled to a mountain bicycle, and this arrangement enables the lighting of six halogen lamps, if a cyclist pedals fast enough. Such ...
