    Abstract: An alpha type Stirling engine is provided and comprises an expansion cylinder and a compression cylinder, a regenerator, a cooler, and a heater. Each one of the expansion cylinder and the compression cylinder has a movable piston connected to a respective linear electric generator/motor, wherein the Stirling engine further comprises a control unit which is operatively connected to the linear electric generators/motors and which is configured to control the linear electric generators/motors individually so as to enable a different stroke length and/or motion profile of the piston in the expansion cylinder compared to the piston in the compression cylinder.

    Abstract: Provided are systems and methods for transport vehicles using recyclable metallic fuels. The method includes capturing fuel products, including a metal oxide and unburnt fuel from the combustion of a metallic fuel, storing the unburnt metallic fuel and the fuel products, and recycling the metal oxide to recreate the metallic fuel and/or byproducts. Heat generated by the combustion and/or sintering of the metallic fuel may be transferred to a working fluid to drive the production of electricity and/or to provide propulsion in land, air and water vehicles and spacecraft. Furthermore, the thermal energy harvesting system may be used to generate electricity. The system includes a thermal (heat) engine having an induction heating assembly for heating the metallic fuel. Processes for complete combustion of the metallic fuel and recycling the metallic fuel in a sintering loop are described.

    Abstract: A multi-stage Stirling cycle machine and a steady-state operating parameter control method therefor are disclosed. In the Stirling cycle machine, a mechanical energy input piston, a mechanical energy transfer double-acting free piston, and a mechanical energy output piston constitute a plurality of Stirling working units which are arranged in stages. The mechanical energy input piston is connected to a mechanical energy input apparatus. The mechanical energy output piston is connected to a mechanical energy output apparatus. When the Stirling cycle machine is used as an engine, a relatively small amount of mechanical energy is input into a mechanical energy input piston in a set of pistons, the mechanical energy is amplified by a multi-stage Stirling unit, and a relatively large amount of mechanical energy is then output by a mechanical energy output piston.
