Performance enhancement study for simple solar still

Abstract

The population increase and economic development in addition to newlineglobal warming are creating a worldwide imbalance between supply and newlinedemand of fresh water Sources of fresh water must be found and the most newlinelikely sources are the great oceans and seas that can be distilled by various newlinemethods including the utilization of solar energy Most of the existing newlinedesalination plants use fossil fuel as a source of energy The desalination newlinetechniques such as multieffect evaporation multistage flash distillation thin newlinefilm distillation reverse osmosis electro dialysis are energy intensive and the newlineoperating cost is high On the other hand the use of conventional energy newlinesources hydrocarbon fuels to drive these technologies has a negative impact newlineon the environment newline newline
