    Beautiful work. Anything that can run on that small flame is amazing.

      It just gently ticks away, no fuss. I'm always amazed by how little heat is needed.

    Magnum Stirling Engine
    1. Operation Overview
    The Magnum Stirling Engine uses a Stirling engine heated by a magnetic induction system. This engine converts heat into mechanical energy, which is used to generate electricity. The energy generated is stored in multiple batteries for future use. The system is efficient because magnetic induction requires little energy to heat the engine chamber, and the flywheel maintains continuous rotation to power an electric generator.
    2. Engine Operation
    2.1. Magnetic Induction Heating
    The heart of the system is magnetic induction heating. Magnetic coils are placed around the hot chamber of the Stirling engine. When fed with a small electric current, they create an alternating magnetic field that generates heat without physical contact, heating the engine chamber. The heat generated causes the gas (usually air or helium) inside the engine to expand. Magnetic induction is highly efficient, using little electrical energy. Sensors monitor the temperature inside the engine and adjust the coil current to maintain energy efficiency and prevent overheating.
    2.2. Stirling Cycle
    The Stirling engine uses the temperature difference between the hot chamber (heated by induction) and the cold chamber to move its pistons. The alternating expansion and compression of the gas inside the engine generates rotational movement on the main shaft. The gas expands when heated, pushing the piston and moving the shaft. The gas cools in the cold chamber, contracting and completing the cycle, generating continuous movement.
    2.3. Flywheel
    The flywheel is connected to the Stirling engine shaft and serves to store mechanical energy. It acts as a stabilizer of the rotational movement, ensuring that the rotation is continuous and smooth, even when the engine cycle is not at its maximum power point. The flywheel accumulates mechanical energy and provides constant torque to the system, smoothing out fluctuations in movement.
    2.4. Electricity Generation
    The flywheel is connected to an electric generator. As the flywheel rotates, it transforms mechanical energy into electricity. The generator is a permanent magnet type, efficient even at low speeds, typical of Stirling engines. The rotational movement of the flywheel is converted into electrical energy by the generator.
    3. Energy Storage and Consumption
    3.1. Battery Storage
    The energy generated by the electric generator is stored in multiple batteries, usually lithium-ion or LiFePO4, known for their durability and high storage capacity. A battery management system (BMS) is used to manage the distribution of the charge between the batteries, ensuring that none are overloaded and optimizing efficiency.
    3.2. Energy Consumption
    The energy generated can be used to power the engine systems (such as magnetic induction) or be stored for later use. The magnetic induction system uses little electricity to heat the engine chamber, creating an efficient cycle where most of the energy generated is stored or can be used for other devices.
    4. Complete Operation Cycle
    5. Initial Heating: The magnetic induction system heats the hot chamber of the Stirling engine.
    6. Stirling Cycle: The expansion and compression of the gas inside the engine generates rotational movement.
    7. Flywheel Movement: The flywheel stores mechanical energy and maintains a continuous rotation.
    8. Electricity Generation: The rotational movement of the flywheel is converted into electricity by the generator.
    9. Energy Storage: The energy generated is stored in multiple batteries for later consumption.
    10. Temperature Control: Sensors adjust the current in the induction coils to maintain the ideal operating temperature.
    This cycle makes the Magnum Stirling Engine with magnetic induction an efficient solution for converting thermal energy into electrical energy, with a focus on sustainability and low energy consumption.

I only as as I am building my own sterling engine but having difficulty building the pistons. Take care and hope to hear from you soon. Kind regards Bret

    Been researching this for a while and from what I've gathered they'd have zero torque you could put your pinky finger on a big one and bring it to a halt very neat and interesting but basically useless for anything requiring more torque than a fan, haven't seen anyone successfully power a generator with one yet

      I've seen that most Stirlings run on one atm of pressure. How high do you think we can take the pressure and, therefore, torque before it breaks?
      As far as I can tell, the cylinders are closed, which might make it possible to overpressure it irrelative to the sky.

      @robdawkins  2 роки тому +1

      I hope this helps: A Stirling engine has a sealed cylinder with one part hot and the other cold. The working air inside the engine is moved by a mechanism from the hot side to the cold side. When the air is on the hot side it expands and pushes up on a piston.
      When it moves back to the cold side it contracts.

    information. poorly designed. NO output shaft. TOO slow. in part, because of the over-long hot-side stroke length.! a thermosiphon-based cooling system in which the reservoir is not optimal located; eg., fully 'above' the hot process. a Well-designed heat engine needs no supplemental cooling. cheers
