Abstract: The present invention is a multi-source powered audio playback system which integrates multiple energy charging sources that charge an internal battery, with a digital audio player and an analog audio amplifier and multiple audio outputs. In one embodiment, the present invention includes a mechanical power generating means, rectifier, solar power cell, blocking circuit, external AC/DC charger, blocking circuit, charge control circuit, at least one rechargeable battery pack, a power control circuit, a digital audio player, at least one mass memory device with secure content, voltage regulator circuit, power supply de-coupling circuit, analog audio amplifier, output circuit and a waterproof speaker. The audio content is secured by the elimination of a consumer usable data port and/or password protection. The invention optimally provides an audio output signal that is sufficient for private, room or group use.

Abstract: An apparatus and method for the creation, placement and control of an area of electrical ionization within an internal combustion engine combustion chamber or a fuel burner for a furnace is disclosed. A furnace includes a fuel source, a fuel burner, a plasma nozzle and igniter assembly, and the associated housing and flue structures. The plasma nozzle and igniter assembly is arranged so that the fuel sprayed out from the nozzle into the combustion area passes through or in close proximity to the area of plasma ionization. A fuel burner equipped with this electrical ionization device has its fuel efficiency enhanced by the complete and immediate combustion of substantially all of the fuel that passes through the area of plasma ionization. Exhaust gas recirculation using this system is also disclosed.
