A system for smoking or grilling food that uses a wood pellet burner to provide the heat and smoke for the smoking/grilling process and wherein all the electrical requirements for the system are provided by a thermoelectric generator that receives thermal energy from the wood pellet burner and converts a portion of that thermal energy into electricity, and wherein a microcontroller is used to accurately regulate the smoking or grilling temperatures and the temperatures of the thermoelectric generator.

A pellet hopper for use in a pellet grill includes a first bottom panel, a second bottom panel, and a third bottom panel. Each bottom panel has an inner edge that partially defines a pellet evacuation opening. The first, second, and third bottom panels form respective first, second, and third nonzero angles relative to a horizontal plane. In this way, each bottom panel tilts downward toward the pellet evacuation opening.

A solid pellet fueled apparatus having a duel auger system and multi/high speed auger motor is disclosed. The duel auger may include first and second auger blades mounted on a single auger shaft having blade pitches configured to convey solid fuel in opposite directions towards a central burn pot. Each auger blade may service a separate solid fuel compartment provided in a single hopper. The auger motor may have a high-speed setting that may be selected for solid fuel clean out.

Devices and methods for outdoor heating. A stove device includes a fuel system attached to a combustion chamber to deliver fuel from a hopper of the fuel system to the combustion chamber for combustion in a firepot assembly positioned inside the combustion chamber. A distance between a chute of the fuel system and the firepot assembly is adjustable to change an amount of fuel for combustion and thereby control temperature of combustion. The distance may be decreased to decrease the temperature and may be increased to increase the temperature

A portable grill with a battery power system includes a primary direct-current power source and a secondary direct-current power source. The primary power source can connect onto the outside of the grill via a clip. The secondary power source, which can be disposed within the grill so as not to be exposed to outside elements, can continue to power the grill when the user removes and/or replaces the primary power source during the operation of the grill. A user feedback system can remotely alert the user with information regarding the time or power remaining in the primary power source.

A solid pellet fueled heater having a base unit with forced air blowers and a dual tube chimney structure is disclosed. The dual tube chimney structure may be used to warm incoming air for distribution around the heater. The pellet heater may also include a dual auger system and multi/high speed auger motor. The dual auger may include first and second auger blades mounted on a single auger shaft having blade pitches configured to convey solid fuel in opposite directions.
