Results of a techno-economic feasibility evaluation of some micro-hydro power (MHP) plants being planned and implemented for remote village power supply in the state of Uttaranchal in India are presented. The capital cost of MHP plants in the capacity range of 20–100 kW (including cost of...

The top cover of a flat plate solar collector is generally exposed to wind. In indoor experiments it is necessary to simulate this wind. Correlations have been developed for the wind heat transfer coefficient over flat horizontal surfaces exposed to forced air flow, produced by industrial fans...

The thermal performance of any focussing-type solar cooker, where an unglazed/uuninsulated cooking pot is often used, depends to a great extent on wind conditions. Moreover, these cookers need frequent adjustments to track the Sun in order to keep the focus always at the bottom of the cooking...

This paper presents the results of a study undertaken for identifying niche areas in India where renewable energy based decentralized generation options can be financially more attractive as compared to grid extension for providing electricity. The cost of delivering electricity in remote areas...

A framework for financial evaluation of a box-type solar cooker, using cost functions for its capital cost, has been developed. The annual benefits accrued to the user are quantified in terms of number of meals cooked per year and monetary worth of the fuel saved per meal. Expressions for some...

The top heat-loss factor (Ut) of a box-type solar cooker varies with plate temperature, wind heat-transfer coefficient and ambient temperature. A method for correlating Ut with these variables is presented for a cooker with double glazing. A set of equations is developed for correlating data...

Thermal performance of a parabolloid concentrator solar cooker depends greatly on the wind speed. Experiments have been conducted to study the effect of wind speed on heat loss parameter F′UL and hence on thermal performance of the cooker under simulated wind conditions. Correlations have been...

Three somewhat different experimental test procedures may be employed for the determination of the optical efficiency factor, F′ηo, of a parabolloid concentrator solar cooker. The procedures are briefly described and typical results presented. The merits and drawbacks of each test procedure...
