An apparatus includes a heater having a combustion chamber, an inlet port to provide fuel into the combustion chamber, and an outlet port to expel exhaust gases from the combustion chamber. The combustion chamber may be insulated. An exhaust channel is operably coupled to the outlet port and is configured to convey exhaust gases away from the combustion chamber. A nozzle, such as a de Laval nozzle, is incorporated into the exhaust channel and is configured to accelerate the exhaust gases through the exhaust channel. A tesla turbine is operably coupled to the exhaust channel and is configured to generate rotational power from the accelerated exhaust gases. In certain embodiments, disks of the tesla turbine are coated with a catalytic material to break apart unburned particles in the exhaust gases. A corresponding method is also disclosed.

F02C 3/26 - Gas-turbine plants characterised by the use of combustion products as the working fluid using a special fuel, oxidant, or dilution fluid to generate the combustion products the fuel or oxidant being solid or pulverulent, e.g. in slurry or suspension
F23B 80/04 - Combustion apparatus characterised by means creating a distinct flow path for flue gases or for non-combusted gases given off by the fuel by means for guiding the flow of flue gases, e.g. baffles
F01D 1/36 - Non-positive-displacement machines or engines, e.g. steam turbines characterised by non-bladed rotor, e.g. with drilled holes using fluid friction
A highly efficient indoor heating system and device is described. The device is equipped with an internal chimney, as well as vents that are configured to maximize the draft applied to the flame housed within a stove combustion area. The heater is configured to reach temperatures exceeding 300 degrees Fahrenheit in approximately ten minutes. A gravity fed fuel tube, potentially in communication with a wood pellet hopper, is configured to deliver fuel to the stove of the heater. Heat is distributed throughout the structure of the device, and a convection chamber within the device ensures that heat generated is not quickly lost via exhaust.
