This one popped up in a scan I did last night, $ESIV ~ Check this out - high demand industry: "The desalination market is driven by growing demand for water and rising marginal costs of supply. Falling costs of desalination have dramatically increased the size of the potential market. Traditional desalination poses an environmental issue because it involves energy use and brine discharges. As a whole, the desalination industry is unconsolidated, with a large number of small and medium sized players serving different niches. The strongest players can expect strong market growth as well as increases in market share."
