an electrostatic phase change generating apparatus is described . the apparatus causes a change of state to occur in an input gas , for example , ambient air . the electrostatic phase change generating apparatus removes moisture from air , and may be used to generate water from air , dehumidify air , cool air , and the like . the ability to generate water from air has global importance as the need for clean water increases each year . the electrostatic phase change generating apparatus uses high voltage but low current allowing for very energy efficient operations . the electrostatic phase change generating apparatus uses a phase change vessel containing a liquid , a bubbler immersed in the liquid for conveying a gas , and a high voltage source to bias the liquid with respect to an upper electrode .
