Enhanced Catalysts & Apparatus for Heat Generation Internal Combustion Engines and Thermoelectric Power

Background: As electronic devices become increasingly complex and widespread so does the demand for portable electric power generation. Portable electronic devices powered by traditional batteries are limited by their short lifetime energy capacity and relatively limited accessibility. Portable generators run on hydrocarbon fuels including kerosene and diesel overcome the limitations of batteries but their engine-based design results in noise pollution and recurring maintenance. An alternative to expensive and fuel-type limited fuel cells thermoelectric generators can produce power from any heat source—translating to extended lifetime high energy capacity widely accessible noiseless durable power production. Technology Description: The invention improves thermoelectric power generation in multiple ways by providing for combustion in the lean burn condition extracting more heat than existing technologies and allowing for combustion of fuels that would otherwise not be useable. In the looped-configuration combustion apparatus to achieve high efficiency the intake air and fuel is pre-heated by an integrated heat exchanger using exhaust products and the heat is extracted to the thermoelectric generator using the thermal conduction of the porous media. To burn alternative fuels a novel fuel vaporization metallic porous foam was created to uniformly and efficiently distribute it within the combustion loop apparatus. A subsequent mixing chamber incorporates the air fuel mixture to improve the fuel’s combustibility which occurs in the proceeding catalytic porous media. Applications: 1) Internal combustion engines: water heaters gas stoves boilers portable generators 2) Portable thermoelectric power generators: for camping military use natural disaster aid


1) More efficient combustion 2) Fuel flexibility: power from lean mixtures 3) Smaller equipment requirements 4) Little-to-no maintenance 5) No complicated control system needed 6) Less environmental contamination when burning low-calorific fuels
