Systems, methods, and apparatus relating to the use of Stirling engine technology to convert heat, such as from solar radiation, to mechanical work or electricity. Apparatus, systems, components, and methods relating to energy converting apparatus are described herein. In one aspect, the invention relates to the field alignment of panels and the assembly of a concentrator. In another aspect, a passive balancer is used in combination with a ring frame and other moving masses to reduce engine forces and vibration on the structure of the energy converting apparatus while maintaining properly constrained alignment of various suspended masses. In yet another aspect, the invention relates to various over-insolation control and management strategy to prevent overheating of the energy converting apparatus or components and subsystems thereof.

1. A method for reducing over-insolation of a heat exchanger, the method comprising the steps of: providing a heat exchanger having a surface area for absorbing solar radiation;concentrating solar radiation on the surface area of the heat exchanger such that the concentrated solar radiation impinges on a portion of the entire surface area of the heat exchanger; andmoving the concentrated solar radiation about the surface area of the heat exchanger in a substantially circular pattern at about 1 to about 30 revolutions per minute. 2. A method for reducing over-insolation of a heat exchanger, the method comprising the steps of: providing a heat exchanger having a surface area for absorbing solar radiation;concentrating solar radiation on the surface area of the heat exchanger such that the concentrated solar radiation impinges on a portion of the entire surface area of the heat exchanger; andmoving the concentrated solar radiation about the surface area of the heat exchanger in a randomized movement of the concentrated solar radiation. 3. A method for reducing over-insolation of a heat exchanger, the method comprising the steps of: providing a heat exchanger having a surface area for absorbing solar radiation;concentrating solar radiation on the surface area of the heat exchanger such that the concentrated solar radiation impinges on a portion of the entire surface area of the heat exchanger;moving the concentrated solar radiation about the surface area of the heat exchanger in a pattern; and reducing the portion of the surface area onto which concentrated solar radiation impinges when the temperature of the heat exchanger reaches a predetermined limit, thereby reducing thermal input. 4. A method for reducing over-insolation of a heat exchanger, the method comprising the steps of: providing a heat exchanger having a surface area for absorbing solar radiation;concentrating solar radiation on the surface area of the heat exchanger such that the concentrated solar radiation impinges on a portion of the entire surface area of the heat exchanger;moving the concentrated solar radiation about the surface area of the heat exchanger in a pattern; andreducing the portion of the surface area onto which concentrated solar radiation impinges when the temperature of the heat exchanger reaches a predetermined limit, thereby reducing thermal input, wherein the heat exchanger is in thermal communication with an energy converting apparatus, the energy converting apparatus selected from the group consisting of a Stirling engine, chemical energy conversion device, a thermal energy storage device, a gas turbine, a multi-cylinder engine, a multi-piston engine, a steam turbine, a steam power tower, a fuel cell, and a water-based energy generation systems. 5. A method for reducing over-insolation of a heat exchanger, the method comprising the steps of: providing a solar concentrator;providing a Stirling engine;providing a heat exchanger having a surface area, the heat exchanger being in thermal communication with the Stirling engine; providing an aperture between the heat exchanger and the solar concentrator;aligning the solar concentrator and the aperture such that a fraction of the solar radiation from the solar concentrator passes through the aperture, wherein the fraction of solar radiation impinges on a portion of the surface area of the heat exchanger; andmoving the solar radiation about the surface area of the heat exchanger. 6. The method of claim 5, comprising the step of reducing the portion of the surface area onto which concentrated solar radiation impinges when the temperature of the heat exchanger reaches a predetermined limit, thereby reducing thermal input. 7. The method of claim 6, comprising the step of moving the concentrated solar radiation such that substantially no concentrated solar radiation impinges on the heat exchanger when a predetermined maximum temperature, power, pressure, swept volume, resistance, current, or position, is reached. 8. The method of claim 5, further comprising the steps of during non-peak solar conditions, directing most of the solar radiation from the solar concentrator through an electromagnetic radiation path; and during peak solar conditions, reducing the amount of solar radiation which passes through the electromagnetic radiation path and moving the solar radiation about the surface area of the heat exchanger, thereby reducing thermal input, spreading hot spots, reducing the rate at which the heat exchanger heats, and/or maintaining coolant temperature. 9. The method of claim 5, further comprising the step of when the heat exchanger reaches a predetermined temperature limit, reducing the amount of solar radiation which passes through the aperture, thereby reducing the amount of solar radiation impinging on the heat exchanger. 10. The method of claim 9, wherein the step of reducing the amount of solar radiation comprises misaligning the solar concentrator and the aperture.
