  • Patent number: 10072240
    Abstract: Present invention relates to a modular system for fabrication of a biocolumn for generating fuel stocks. The biocolumn of independent units called modules and which function as independent units and can be assembled together to fabricate a biocolumn. These modules can be assembled together to form various zones of biocolumn. Fuel stocks can be prepared by inputting a nutrient, a renewable energy source, photon energy and a carbon source into said zones and outputting fuel stock and by products from zones. The zones are interconnected so that byproducts from each zone can be recycled as input or transformed into product.
    Type: Grant

  • Patent number: 6931848
    Abstract: The present invention provides heat exchanging elements for use in Stirling engines. According to the present invention, the heat exchanging elements are made from muliple platelets that are stacked and joined together. The use of platelets to make heat exchanging elements permits Stirling engines to run more effiecient because the heat transfer and combustion processes are improved. In one embodiment, multi-stage combustion can be introduced with platlets, along with the flexibility to use different types of fuels. In another embodiment, a single component constructed from platelets can provide the heat transfer rquirements betweeen the combustion gas/working gas, working gas in the regenerator and the working gas/coolant fluid of a Stirling engine. In another embodiment, the platelet heat exchanging element can recieve solar energy to heat the Stirling engine's working gas. Also, this invention provides a heat exchanging method that allows for multiple fluids to flow in opposing or same direction.
