Wind energy has proven a best alternative to fossil fuel based energy and is environmental friendly also. In India, a small family of having 4/5 persons consumes about 1.5 Kw electricity per day. Hence there is a huge potential for mini wind mills & necessity of developing horizontal axis wind turbine machine of capacity of 200 watts to 1500 watts, which can run on average wind velocity of 2 to 3 m/s. Authors has made an attempt to resolve this problem. This paper deals with the design, manufacture and testing of HAWM of 500 W for performance evaluation for domestic application. The rotor blades are aerodynamically designed and are made up of FRP weighing 500 gm. each. The Permanent Magnet Generator is having 16 poles. The machine is dynamically balanced before fitting on pole at roof top for testing. During performance evaluation it is observed that the machine runs on 2.7 m/s, against the design cut in wind speed of 3.5 m/s. During field experiments, it has been observed that, small horizontal axis wind turbine reached maximum 957 RPM and developed 19.2 amperes current during the continuous testing period of 180 hours as per code of standards. This prototype has potential for commercializing the product for domestic application. © 2013 IEEE. Source

The paper describes the experimental results of black epoxy coated aluminium receiver with prototype parabolic trough made of fiberglass reinforced plastic with aluminium receiver, and its aperture area of collector coated with aluminum foil with reflectivity 86%. From hotter climate context, there is wide market available for low cost solar concentrating technologies. These technologies can be applicable for domestic applications as well as industrial process heat. Along with low temperature applications there are several potential fields of application for solar thermal energy at medium-high temperatures (90°C-200°C). Described aluminum receiver coated with black proxy material and glass cover and without glass cover has been tested with line focusing parabolic trough. Instantaneous efficiency of 52% and 38 % has been achieved with glass covered receiver and without glass covered receiver respectively. Performance evaluation of prototype system has been done with two flow rates 0.023kg/s and 0.030 Kg/s during month of April and May 2010 at Shivaji university, Kolhapur [Latitude: 16.42°N, Longitude: 74.13°W]. © 2013 IEEE.

The paper explores the experimental results of the prototype compound parabolic trough made of G.I and silver coated selective surface. The performance of collector has been evaluated with three kinds of receivers' coated with two kinds of receiver coatings black copper and black zinc and top cover. This line focusing parabolic trough yields instantaneous efficiency of 60 % with top cover. A simple relationship between the parameters has been worked out with the regression analysis. Actual field experimentation for performance evaluation of prototype system has been done during month of April and May 2012 at Shivaji university, Kolhapur [Latitude: 16.42° N, Longitude: 74.13°W].

Concentrated solar collectors have high efficiency. Therefore, when concentrating collectors are used for water heating application, the system yields higher efficiency. From a hot climate perspective, there is a huge potential available for low-cost solar water heating systems. With the system described in this paper, the needs of hot water in the domestic sector can be fulfilled instantly. Authors used the parabolic dish collector for instant water heating. This paper describes the effect of variation of mass flow rate on performance of the parabolic dish water heater prototype. Design of the solar parabolic dish collector consists of a novel truncated cone-shaped helical coiled receiver made up of copper at focal point. This prototype was evaluated for its performance during the month of April and May 2010. © 2013 Taylor & Francis. Source

The paper explores the experimental results of the prototype compound parabolic trough made of mild steel and silver-coated selective surface. This prototype has been tested with top cover. The performance of the collector has been evaluated with two kinds of receivers coated with three types of black coatings. First receiver is of copper coated with black copper, second receiver is of mild steel coated with black copper and third receiver is of copper coated with black zinc. From actual field experiments, it has been observed that the efficiency of the system achieved with copper receiver coated with black copper is comparatively higher than the other two types of receivers. A simple regression analysis is used to correlate the thermal performance parameters of the system. © 2016 Taylor & Francis Source
