JOHNSON AMBIENT ENERGY CONVERTER

An ambient energy converter derives energy from variations in ambient temperature and humidity. The ambient energy converter includes a controller, a first chamber containing a first hygroscopic ionic solution and a second chamber containing a second ionic solution. Each chamber includes an electrochemically reactive electrode in contact with the solution therein. The chambers are separated by an ion conductive membrane that conducts an ion species of the solutions. The first solution is coupled to ambience and maintains water vapor pressure equilibrium with changes in ambient humidity. The process results in water condensing and evaporating into and out of the solution with increases and decreases in ambient humidity respectively. The second solution is sealed within a chamber and coupled to the hygroscopic solution by an ion conductive barrier. Water vapor condensing into or evaporating from the hygroscopic solution creates a concentration differential across the ion conductive barrier that generates electricity.
