20080277263 | METHOD AND APPARATUS FOR TREATMENT OF IMPOTABLE WATER - Apparatus and method are provided for treatment of impotable water and for optionally simultaneously creating surplus electricity. Briefly, water is marshaled through a series of chambers by variances in pressure which are created as the water changes state from liquid to gas and from gas to liquid.
