Abstract
A power source employs an environmental energy extractor. The environmental energy extractor operates to extract energy from the environment and provides the extracted energy either to power an electronic device, or to a storage device coupled to a battery charger for storing the extracted energy. The environmental energy extractor can include one or more energy modules. Each energy module is for extracting environmental energy and for providing the extracted energy to either the electronic device or the storage device. When more than one energy module is employed, the energy modules are configured such that the extracted energy provided by each module is summed, and the collective extracted energy of all the energy modules is provided to the electronic device or the storage device.
