D. C. Polarography * Introduction: - Polarography is a particular case of general electro analytical technique known as voltametry. These methods are used to study the decomposition and quantitative analysis of solution. Principle: - It is a rapid and accurate technique in which electrolysis of experimental solution is carried out by using one electrode of comparatively large surface area (i.e. non-polarisable electrode) and the other electrode having a very small area (polarisable electrode)

Flying Wind Generators Flying wind generators are the future of wind energy. This article talks about the replacement of wind turbines for “windmills in the sky”. Instead of using the current wind turbines‚ Bryan Roberts‚ and engineer at University of technology in Sydney‚ Australia‚ decided to fly wind turbines into the jet stream 15‚000 to 45‚000 feet into the sky with winds up to 200 miles per hour. With 600 of these producing 20 megawatts each could power two Chicago sized cities. The

markets of Sandwip are served by diesel micro-grid run by several diesel generator operators who provide services for about 5 to 8 hours per day. Besides‚ several diesel generators are used by several shop owners for captive consumption. Average tariff rate being charged to the customers by the diesel operators currently range between BDT 53 per kWh and BDT 60 per kWh. Bangladesh Power Development Board also has diesel generator that supplies electricity to mainly government offices. Several non-government
