Patent ID: 6957543

Claim:
A water producing machine comprising: a first air path; a second air path; a first valve controlling flow of ambient air into said first air path; a first heat exchanger transferring heat between said first and second air paths and having a first water output; a cooling turbine expanding air passing through said first air path and having an air input connected to said first heat exchanger and an output, said cooling turbine adapted to expand the ambient air passing there through and output expanded air; a second heat exchanger transferring heat between said first and second air paths and being connected to the output of said cooling turbine, said second heat exchanger having a second water output; a compressor compressing the air passing through said first air path and having an air input connected to said second heat exchanger, said compressor compressing the expanded air passing through said second heat exchanger; drive means for driving said cooling turbine and said compressor; a second valve controlling flow of the ambient air into said second air path; and a fan connected to said second valve and adapted to blow the ambient air through said second heat exchanger and said first heat exchanger; wherein the ambient air blown by said fan through said second heat exchanger is cooled by the expanded air passing through said second heat exchanger causing condensation within said second heat exchanger and water to be output from said second water output, and wherein the ambient air blown by said fan through said first heat exchanger causes the ambient air fed into said first heat exchanger to be cooled causing condensation within said first heat exchanger and water to be output from said first water output.
