The cost of irrigation water has been computed for two shallow-well, water-pumping windmill designs in India. An empirical relationship for variation of the overall efficiency of the windmills with wind-speed is established. Weibull parameters are computed for Indore, Madras and New Delhi and...
Indoor air pollution, caused by the combustion of four biofuels (fuelwood, dung cakes, agri-residue, and a mixture of fuelwood and dung cakes) in a traditional and an improved mud cookstove (Sugam-II), has been studied. The concentrations of three gaseous pollutants (CO, NO2, HCHO) were measured...
Steel manufacturing is energy-intensive and hence a significant contributor of CO2 emissions. We project steel demand in India using regression analysis. A linear dynamic programming model has been developed to analyse the supply options and estimate the energy demand and CO2 emissions from the...
A simple framework for the estimation of fly ash utilisation potential in India is presented. It also enables estimation of associated resource savings. Results of some typical calculations are presented and described briefly.
The suitability of using biomass briquettes to substitute coal is debatable, as a substantial amount of energy is required for briquetting of biomass. In the present work, an attempt to evaluate the energetic viability of briquetting of agricultural residues compared with the energy embodied in...
