Island Sky - Has developed low cost patented air to water making machines which draw water vapour from the air & convert into pure filtered drinking water.
Domestic model produces 50 litres per day, commercial one produces 1,100 per day.
If (big if) this company can deliver( as they all promise), could be big upside due to cost & scarcity of water. Could see the commercial model being used around the planet in emergency situations where water is cut off or contaminated. Just hook up to a generator.
Being IPO 7/12/07 @ 0.20c (down to .15c now .23c) not much volume but worth a look.
