This invention provides a portable combustion device that provides a cleaner combustion, provides a more efficient overall combustion through the use of a fan that directs a predetermined volume of airflow over the combustible fuel—typically wood or similar cellulose-based biological solids and provides a cooking surface that is a grill top. The combustion device has a combustion chamber into which the fuel source is placed for combustion. Mounted to the side of the combustion chamber is a housing that encloses the TEG, which generates an electrical output, based on a difference in temperature on opposing sides. Mounted onto the TEG housing and protruding into the combustion chamber through a small passageway is a heat-conducting probe and heat-conducting probe base unit.

A battery charger for electronic devices and an electronic device are disclosed. In one embodiment, a battery charger housing forms a portion of an outer device shell or a protective case cover. Capacitors are located within the battery charger housing that include opposing spaced plates having contact segments thereon. An output power increasing, electrically resistive fluid is held within and partially fills an enclosed chamber that is boundaried by the contact segments. In response to movement of the electronic device, induced relative motion between the output power increasing, electrically resistive fluid and contact segments varies the fluid-contact segment contact within the enclosed chamber, thereby inversely alternating the capacitance between the pair of capacitors and triboelectrically generating an electrical charge. An electronic circuit, which is coupled to the opposing spaced plates, is configured to transfer the electrical charge to a battery associated with the electronic device.
