A large-size solar cooker for animal feed has been designed, developed and tested. The cooker employs locally available materials of low cost, e.g. pearl-millet husk and horse excreata. The commercial materials required for its fabrication are plain glass, mild steel angle and sheet, wood and...

Two simple solar cookers, one made of clay and locally available materials, and the other of exfoliated vermiculite and cement tiles, have been designed, fabricated and tested. The comparative performance of both cookers is described, and their efficiencies are 22.6 (clay) and 24.9%...

A lumped-parameter rainfall-runoff model is used to predict the long-term natural variability of runoff from approximately 100 years of daily rainfall temperature data. Two catchments from the Clarence Basin in Australia illustrate the simplicity and accuracy of the approach which can work quite...

This work investigates the design and modeling of fully integrated processes which utilize renewable feedstocks as raw materials by evaluating alternative technology options and possible process integrations to select the optimal configuration according to calculated process yields and economic...
